The article provides information on the UN Global Indigenous Youth Forum in October 2023, held at the Food and Agriculture Organization (FAO) headquarters in U.S. It mentions that the conference was focused on addressing the challenges faced by Indigenous youth, their food systems, and knowledge, as well as climate action and biodiversity conservation.

This paper provides a review and comparison of strategies to increase forest carbon, and reduce species losses for climate change mitigation and adaptation in the United States. It compares forest management strategies and actions that are taking place or being proposed to reduce wildfire risk and to increase carbon storage with recent research findings. International agreements state that safeguarding biodiversity and ecosystems is fundamental to climate resilience with respect to climate change impacts on them, and their roles in adaptation and mitigation. The recent Intergovernmental Panel on Climate Change report on impacts, mitigation, and adaptation found, and member countries agreed, that maintaining the resilience of biodiversity and ecosystem services at a global scale is "fundamental" for climate mitigation and adaptation, and requires "effective and equitable conservation of approximately 30 to 50% of Earth's land, freshwater and ocean areas, including current near-natural ecosystems." Our key message is that many of the current and proposed forest management actions in the United States are not consistent with climate goals, and that preserving 30 to 50% of lands for their carbon, biodiversity and water is feasible, effective, and necessary for achieving them.

Participatory research involves members of interested communities who work with researchers to apply their joint skills and experience to explore issues of mutual concern. There is an increasingly explicit federal mandate for participatory research efforts involving stakeholder groups in public land management. This paper presents a case study of one effort ongoing in the Hayfork Adaptive Management Area (AMA) on the Six Rivers and Shasta-Trinity national forests of northern California. There, a network of U.S. Forest Service staff, scientists, local nongovernmental organizations (NGOs) and nontimber forest product harvesters (wildcrafters) has been working to address ecological, economic, and social aspects of harvesting nontimber forest products (NTFP) from public land. This paper discusses the challenges of NTFP management on public lands and analyzes participatory research as an approach for addressing some of these challenges. [ABSTRACT FROM PUBLISHER]

Terrestrial and ocean ecosystems are increasingly under threat from an array of anthropogenic pressures. And while threats mount, how people view and value nature is changing. In the United States (U.S.) in particular, there is a shift away from viewing nature as something to 'dominate,' as evidenced in the decline in hunting. However, it is unclear if or how opinions around environmental issues and conservation need might differ when comparing ocean versus terrestrial ecosystems, especially given the prevalence and continued importance of wild capture fishing in the U.S. We employed two national parallel surveys, one focused on oceans, the other land, receiving responses from nearly every state in the U.S. (N = 1,973). While we found only slight, but statistically significant more concern for ocean habitats and animals over terrestrial ecosystems, this did not translate to increased willingness to monetarily support more ocean conservation actions. Using Random Forest models, we also found the best predictor of conservation need was feeling most impacted by environmental issues personally (self and/or community), regardless of ecosystem type. In fact, land versus sea (survey) had the lowest rank in the models, underscoring the importance of general nature-based interactions. Instead, the number of outdoor recreational activities was a highly ranked variable explaining the level of reported impact to self/community, with people who participate in 2 or more activities scoring higher levels of impact, on average. Notably, people who hunt and fish, versus only do one or the other, reported higher levels of impact and participated in more activities overall, providing a more nuanced finding regarding the nature 'dominance hypothesis.' Voting, not political affiliation, was also important in explaining responses, and governmental mechanisms to fund conservation were favored over voluntary. Overall, our results add to the strong existing literature that access and connection to nature is key, but uniquely broad connection may "float all boats," especially when diversified.

In 1997, the US Forest Service initiated public involvement processes in three national forests in the northeastern United States-the Finger Lakes National Forest in central New York, the Green Mountain National Forest in Vermont, and the White Mountain National Forest in New Hampshire and Maine. Citizens' perspectives were sought on forest management prior to determining the changes needed for revising the Land and Resource Management Plans (Forest Plans) as well as to exchange information on management of these three forests. These processes represent a pro-active effort by the US Forest Service to engage communities of interest in dialogue about the management of these national forests. The Forest Service has emphasized the principles of ecosystem management and community partnership in developing these plans. The paper describes the policy framework for forest planning and an outline of the Plan Revision process as developed in the Northeast. It further offers a preliminary analysis of this approach, including lessons to date, their implication for subsequent phases of plan revision processes in the Northeast, and possible relevance for agencies embarking on similar public planning initiatives.

The exotic pet trade poses a major threat to biodiversity conservation. To combat biodiversity loss, it is essential to reduce demand for exotic pets and engage people in civic actions for wildlife conservation. Although messaging has been extensively used in conservation practice, little is known about how it can influence attitudes and various types of actions pertaining to the exotic pet trade. This study examined the impact of conservation messaging in the context of exotic pet ownership and wildlife entertainment visitation as common practices of the exotic pet trade. We randomly assigned participants in the United States to one of five messaging conditions: biodiversity loss and animal abuse (M1), zoonotic disease risks (M2), illegality (M3), social disapproval (M4), and neutral biological information as a control condition (M5). We found that all conservation messages (M1–M4) significantly decreased people's favorable attitudes toward the exotic pet trade and their desire to visit wildlife entertainment. However, conservation messaging did not influence the desire for exotic pet ownership or intentions to take civic actions. Our findings highlight the potential of conservation messaging for attitude change and demand reduction for wildlife entertainment, but different approaches are necessary for promoting more effortful actions such as exotic pet ownership and civic actions.

The U.S. needs a National Biodiversity Strategy (hereafter Strategy). As a nation that places a high value on domestic biodiversity and on being a global leader in biodiversity conservation, the U.S. is failing to live up to its expectations regarding a national Strategy. A Strategy should suggest both legislation and policies and guide our country toward achieving stated objectives. We first propose a process to create a Strategy that involves establishing a government task force and supporting expert advisory panel. We then identify five key elements of a Strategy. First, a Strategy should identify priorities among legislation that impacts biodiversity. At present, conflicting rules lead to administrative uncertainty and inconsistent decisions. Second, a Strategy should create a comprehensive vision for societal participation in biodiversity protection. Current practices comprise a mixture of different levels of commitment to stakeholder participation and social justice. Third, a Strategy should mandate periodic review to better provide the American public a synopsis of how we are faring with our treasured biodiversity. Fourth, a Strategy should be as comprehensive and broad as biodiversity itself, spanning organizational ranges from genes to ecosystems. Finally, a Strategy should provide a structure for achievement that incentivizes public and business and that stimulates innovation, particularly in nature‐based solutions to complex environmental challenges. To help address the biodiversity crisis at home and abroad, the United States should develop and implement a National Biodiversity Strategy to provide essential whole‐of‐government leadership and coordination.

Since the 1980s, the US Pacific Northwest has been shattered by a major environmental policy conflict related to the management of Federal forests. These “timber wars” were similar to forest environmental policy conflicts in several other countries, but were particularly polarized. They resulted in a significant change in Federal forest policy from timber production orientation to biodiversity conservation. The change occurred suddenly and had significant economic and social consequences within the region and beyond, but was embedded in long-term societal and institutional trends. In this paper, I adopt an interpretive approach in order to, first, understand contemporary interpretations of the 1993 policy change and, second, to reconstruct the contemporary discursive ‘landscape’ of the Pacific Northwest including the major resource management paradigms and narratives that guide policy making in this region today. Empirically, my interpretation is mostly built on 37 qualitative interviews with policy stakeholders that were conducted in the summer of 2011. Based on this evidence, the paper argues that there are four narratives circulating amongst policy stakeholders that represent different conceptualizations of the 1993 policy change. Yet, all narratives highlight the importance of environmental strategy making that mobilized the socio-institutional setting in order to prepare and finally achieve the change. Current forest policy in the region is characterized by a policy stalemate resulting from the confluence of diverse institutional, context-related factors and the inability of stakeholders to create enough contradictions or crisis by combining these factors in order to promote change-enabling narratives. Four resource management paradigms compete in the region and, within these, narratives and counter narratives on physical and social events are developed. Current forest policy is dominated by an ecosystem management paradigm, but forest management practices aim to reconcile demands arising from the different paradigms to a certain degree, for instance via the concept of “ecological restoration”. Yet, given that the material base that feeds such compromises is finite, a new crisis in Pacific Northwest forest policy in the future is likely. In conclusion, this paper offers an interpretation of Pacific Northwest forest policy (change) as a process in which social and physical events are ‘discursively mobilized’ by means of narratives that are produced against the background of major natural resources paradigms. This includes the art of ‘discourse agents’ in constructing problematizations and intervention logics to either defend the current policy state or to increase the likelihood of change.

Local extirpations of Pacific salmonOncorhynchusspp. and steelheadO. mykiss, often due to dams and other stream barriers, are common throughout the western United States. Reestablishing salmonid populations in areas they historically occupied has substantial potential to assist conservation efforts, but best practices for reintroduction are not well established. In this paper, we present a framework for planning reintroductions designed to promote the recovery of salmonids listed under the Endangered Species Act. Before implementing a plan, managers should first describe the benefits, risks, and constraints of a proposed reintroduction. We define benefits as specific biological improvements towards recovery objectives. Risks are the potential negative outcomes of reintroductions that could worsen conservation status rather than improve it. Constraints are biological factors that will determine whether the reintroduction successfully establishes a self-sustaining population. We provide guidance for selecting a recolonization strategy (natural colonization, transplanting, or hatchery releases), a source population, and a method for providing passage that will maximize the probability of conservation benefit while minimizing risks. Monitoring is necessary to determine whether the reintroduction successfully achieved the benefits and to evaluate the impacts on nontarget species or populations. Many of the benefits, especially diversity and the evolution of locally adapted population segments, are likely to accrue over decadal time scales. Thus, we view reintroduction as a long-term approach to enhancing viability. Finally, our review of published salmonid reintroduction case studies suggests that large uncertainties remain in the success of reintroduction in establishing self-sustaining populations, particularly for programs employing active methods.

Although flawed, the most powerful tool for protecting biodiversity in the United States is the Endangered Species Act, which requires the use of the best available science to ensure that endangered and threatened species are not put in jeopardy of extinction. Unfortunately, the best available science mandate is virtually meaningless and imposes no additional scientific rigor in agency decision making beyond what is normally required of administrative procedures. In this paper, we propose to define best available science in a way that shifts from a way of using science to a way of doing science, and a sound method of doing science for wildlife management and climate change is via the principles of adaptive management [1]. Adaptive management, as a means of data accumulation and continuous learning, can fulfill and give teeth to the best available science mandate while increasing the adaptive capacity of wildlife management agencies to protect biodiversity in an unpredictably dynamic environment.

We performed a bibliometric analysis of published biodiversity research for the period of 1900-2009, based on the Science Citation Index (SCI) database. Our analysis reveals the authorial, institutional, spatiotemporal, and categorical patterns in biodiversity research and provides an alternative demonstration of research advancements, which may serve as a potential guide for future research. The growth of article outputs has exploded since the 1990s, along with an increasing collaboration index, references, and citations. Ecology, environmental sciences, biodiversity conservations, and plant science were most frequently used subject categories in biodiversity studies, and Biological Conservation, Journal of Soil and Water Conservation, Conservation Biology and Biodiversity and Conservation were most active journals in this field. The United States was the largest contributor in global biodiversity research, as the U.S. produced the most single-country and collaborative articles, had the greatest number of top research institutions, and had a central position in collaboration networks. We perceived an increasing number of both internationally collaborative and inter-institutionally collaborative articles, with the latter form of collaboration being more prevalent than the former. A keyword analysis found several interesting terminology preferences, confirmed conservation's central position as a topic in biodiversity research, revealed the adoption of advanced technologies, and demonstrated keen interest in both the patterns and underlying processes of ecosystems. Our study reveals patterns in scientific outputs and academic collaborations and serves as an alternative and innovative way of revealing global research trends in biodiversity.

In this paper, we first discuss various vantage points gained through the authors’ experience of approaching conservation through a “cultural lens.” We then draw out more general concerns that many anthropologists hold with respect to conservation, summarizing and commenting on the work of the Conservation and Community Working Group within the Anthropology and Environment Section of the American Anthropological Association. Here we focus on both critiques and contributions the discipline of anthropology makes with regard to conservation, and show how anthropologists are moving beyond conservation critiques to engage actively with conservation practice and policy. We conclude with reflections on the possibilities for enhancing transdisciplinary dialogue and practice through reflexive questioning, the adoption of disciplinary humility, and the realization that “cross-border” collaboration among conservation scholars and practitioners can strengthen the political will necessary to stem the growing commoditization and ensuing degradation of the earth’s ecosystems.

Conservation science addresses the complementary goals of preventing future biodiversity loss while sustaining critical human foundations. In this paper we use two case studies focused on land management to discuss how private lands conservation can be more effective by considering how planning and decision making reflects a coupled human and natural system (CHANS). The first case study focuses on conservation easements in the temperate forests of eastern United States; the second focuses on conservation opportunities in Midwestern agroecosystems, in particular the value of agroforestry. For each case study we discuss the natural and human subsystems, how elements and interactions within and between subsystems (as organized by elements of CHANS) create challenges and opportunities for conservation, and the importance of considering relevant scales of subsystems. Review of these case studies demonstrates that additional insight gained by using a CHANS perspective, particularly given how the subsystems interact at different scales, improves identification of important points of social and ecological overlap, ultimately enhancing conservation research, planning, and practice.

As domestic affluence increases, nations advocate for conservation policies to protect domestic biodiversity that often curtail natural resource production activities such as fishing. If concomitant consumption patterns remain unchanged, environmentally conscious nations with high consumption rates such as the U.S. may only be distancing themselves from the negative environmental impacts associated with consuming resources and commodities produced elsewhere. This unintended displacement of ecosystem impacts, or leakage, associated with conservation policies has not been studied extensively in marine fisheries. This paper examines this topic, drawing on case studies to illustrate the ways in which unilateral marine conservation actions can shift ecosystem impacts elsewhere, as has been documented in land use interventions. The authors argue that the U.S. should recognize these distant ecological consequences and move toward greater self-sufficiency to protect its seafood security and minimize leakage as well as undertake efforts to reduce ecosystem impacts of foreign fisheries on which it relies. Six solutions are suggested for broadening the marine conservation and seafood consumption discussion to address leakage induced by U.S. policy. [ABSTRACT FROM AUTHOR]

Coincident with international movements to protect 30% of land and sea over the next decade ("30×30"), the United States has committed to more than doubling its current protected land area by 2030. While publicly owned and managed protected areas have been the cornerstone of area‐based conservation over the past century, such lands are costly to establish and have limited capacity to protect areas of the highest value for biodiversity conservation and climate change mitigation. Here we examine the current and potential contributions of private land for reaching 30×30 conservation targets at both federal and state scales in the United States. We find that compared to publicly owned and managed protected lands, protected private lands (conservation easements) are more often in areas designated as high conservation priority, hold significantly higher mean species richness, and sequester more vulnerable land‐based carbon per unit area. These and related findings highlight the necessity of mechanisms that engage private landholders in enduring conservation partnerships. [ABSTRACT FROM AUTHOR]

Maintaining regional‐scale freshwater connectivity is challenging due to the dendritic, easily fragmented structure of freshwater networks, but is essential for promoting ecological resilience under climate change. Although the importance of stream network connectivity has been recognized, lake‐stream network connectivity has largely been ignored. Furthermore, protected areas are generally not designed to maintain or encompass entire freshwater networks. We applied a coarse‐filter approach to identify potential freshwater corridors for diverse taxa by calculating connectivity scores for 385 lake‐stream networks across the conterminous United States based on network size, structure, resistance to fragmentation, and dam prevalence. We also identified 2080 disproportionately important lakes for maintaining intact networks (i.e., hubs; 2% of all network lakes) and analyzed the protection status of hubs and potential freshwater corridors. Just 3% of networks received high connectivity scores based on their large size and structure (medians of 1303 lakes, 498.6 km north–south stream distance), but these also contained a median of 454 dams. In contrast, undammed networks (17% of networks) were considerably smaller (medians of six lakes, 7.2 km north–south stream distance), indicating that the functional connectivity of the largest potential freshwater corridors in the conterminous United States currently may be diminished compared with smaller, undammed networks. Network lakes and hubs were protected at similar rates nationally across different levels of protection (8%–18% and 6%–20%, respectively), but were generally more protected in the western United States. Our results indicate that conterminous United States protection of major freshwater corridors and the hubs that maintain them generally fell short of the international conservation goal of protecting an ecologically representative, well‐connected set of fresh waters (≥17%) by 2020 (Aichi Target 11). Conservation planning efforts might consider focusing on restoring natural hydrologic connectivity at or near hubs, particularly in larger networks, less protected, or biodiverse regions, to support freshwater biodiversity conservation under climate change.

Forest resources and the flow of ecosystem services they provide play a key role in supporting national and regional economies, improving people's lives, protecting biodiversity, and mitigating the impacts of climate change. Based on the ISI (Institute of Scientific Information) Web of Science (WoS) database, we used a bibliometric approach to analyze the research status, evolution process, and hotspots of forest ecosystem services (FES) from a compilation of 8797 documents published between 1997 and 2019. The results indicated that: (1) research on forest ecosystem services has developed rapidly over the past 23 years. Institutions in the United States and other developed countries have significantly contributed to undertake research on the topic of ecosystem services. (2) The 11 hotpot key focus areas of completed research were payments for ecosystem services, biodiversity conservation, forest governance, ecosystem approaches, climate change, nitrogen, ecosystem management, pollination, cities, ecological restoration, and policy. (3) The trade-off relationships among ecosystem services, ecosystem resilience and stability have become the research frontier in this field. (4) Future research on FES will likely focus on the formation and evolution mechanism of ecosystem services; the interaction, feedback and intrinsic connections of ecosystem services at different scales; analysis of the trade-offs and synergies; unified evaluation standards, evaluation systems, model construction and scenario analyses; in-depth studies of the internal correlation mechanism between forest ecosystem services and human wellbeing; and realization of cross-disciplinary and multi-method integration in sustainable forest management and decision-making.

Natural habitats on private lands are potentially important components of national biodiversity conservation strategies, yet they are being rapidly lost to development. Conservation easements and other means of protecting these habitats have expanded in use and will be most effective if they target private lands of highest biodiversity value and risk of loss. We developed a Biodiversity Conservation Priority Index (BCPI) based on ecological value and risk of habitat loss for remaining areas of natural vegetation cover (NVC) in the northwestern United States and addressed two questions: (1) Which remaining NVC on private lands is the highest priority for biodiversity conservation based on ecological value and risk of development? And (2) are conservation easements in NVC placed preferentially in locations of high biodiversity conservation priority? Drawing on the concept of ecological integrity, we integrated five metrics of ecological structure, function, and composition to quantify ecological value of NVC. These included net primary productivity, species richness, ecosystem type representation, imperiled species range rarity, and connectivity among "Greater Wildland Ecosystems." Risk of habitat loss was derived from analysis of biophysical and sociodemographic predictors of NVC loss. Ecological value and risk of loss were combined into the BCPI. We then analyzed spatial patterns of BCPI to identify the NVC highest in biodiversity conservation priority and examined the relationship between BCPI and conservation easement status. We found that BCPI varied spatially across the study area and was highest in western and southern portions of the study area. High BCPI was associated with suburban and rural development, roads, urban proximity, valley bottom landforms, and low intensity of current development. Existing conservation easements were distributed more towards lower BCPI values than unprotected NVC at both the study area and region scales. The BCPI can be used to better inform land use decision making at local, regional, and potentially national scales in order to better achieve biodiversity goals. [ABSTRACT FROM AUTHOR]

Population change impacts almost every aspect of global change from land use, to greenhouse gas emissions, to biodiversity conservation, to the spread of disease. Data on spatial patterns of population density help us understand patterns and drivers of human settlement and can help us quantify the exposure we face to natural disasters, pollution, and infectious disease. Human populations are typically recorded by national or regional units that can vary in shape and size. Using these irregularly sized units and ancillary data related to population dynamics, we can produce high-resolution gridded estimates of population density through intelligent dasymetric mapping (IDM). The gridded population density provides a more detailed estimate of how the population is distributed within larger units. Furthermore, we can refine our estimates of population density by specifying uninhabited areas which have impacts on the analysis of population density such as our estimates of human exposure. In this study, we used various geospatial datasets to expand the existing specification of uninhabited areas within the United States (US) Environmental Protection Agency's (EPA) EnviroAtlas Dasymetric Population Map for the conterminous United States (CONUS). When compared to the existing definition of uninhabited areas for the EnviroAtlas dasymetric population map, we found that IDM's population estimates for the US Census Bureau blocks improved across all states in the CONUS. We found that IDM performed better in states with larger urban areas than in states that are sparsely populated. We also updated the existing EnviroAtlas Intelligent Dasymetric Mapping toolbox and expanded its capabilities to accept uninhabited areas. The updated 30 m population density for the CONUS is available via the EPA's Environmental Dataset Gateway (Baynes et al., 2021, 10.23719/1522948) and the EPA's EnviroAtlas (https://www.epa.gov/enviroatlas , last access: 15 June 2022; Pickard et al., 2015).

One of the most pressing questions in ecology and conservation centers on disentangling the relative impacts of concurrent global change drivers, climate and land‐use/land‐cover (LULC), on biodiversity. Yet studies that evaluate the effects of both drivers on species' winter distributions remain scarce, hampering our ability to develop full‐annual‐cycle conservation strategies. Additionally, understanding how groups of species differentially respond to climate versus LULC change is vital for efforts to enhance bird community resilience to future environmental change. We analyzed long‐term changes in winter occurrence of 89 species across nine bird groups over a 90‐year period within the eastern United States using Audubon Christmas Bird Count (CBC) data. We estimated variation in occurrence probability of each group as a function of spatial and temporal variation in winter climate (minimum temperature, cumulative precipitation) and LULC (proportion of group‐specific and anthropogenic habitats within CBC circle). We reveal that spatial variation in bird occurrence probability was consistently explained by climate across all nine species groups. Conversely, LULC change explained more than twice the temporal variation (i.e., decadal changes) in bird occurrence probability than climate change on average across groups. This pattern was largely driven by habitat‐constrained species (e.g., grassland birds, waterbirds), whereas decadal changes in occurrence probabilities of habitat‐unconstrained species (e.g., forest passerines, mixed habitat birds) were equally explained by both climate and LULC changes over the last century. We conclude that climate has generally governed the winter occurrence of avifauna in space and time, while LULC change has played a pivotal role in driving distributional dynamics of species with limited and declining habitat availability. Effective land management will be critical for improving species' resilience to climate change, especially during a season of relative resource scarcity and critical energetic trade‐offs.

Abstract: Conflict over endangered species conservation on military lands is becoming increasingly important as militaries attempt to balance an increased operational tempo with endangered species conservation. Successfully managing this conflict has major implications for biodiversity conservation given the US military alone manages over 12 million ha of land providing habitat to hundreds of at risk species, 24 of which are endemic to military installations. This paper provides the first assessment of this issue with a qualitative study of military trainers and civilian natural resource professionals who are employed by the Department of Defense (DoD) at the interface of endangered species conservation and troop training on installations throughout the Southeastern US. Emerging conflicts over endangered species conservation on DoD lands differed from non-military contexts because military structure forced interactions into strict protocols allowing avoidance, but not direct contention. Although all informants officially stated nothing impacted training, training area supervisors described endangered species conservation the greatest threat to training they faced. Despite pointed efforts to avoid engagement and official denial that conflict existed, interactions between the groups were characterized by deindividualization and communication breakdown, residues typically associated with highly escalated conflicts. These findings suggest suppressing conflict may create the same negative outcomes typically associated with prolonged direct conflict, by denying parties the ability to resolve differences. These negative outcomes can be addressed by both acknowledging biodiversity conservation conflict exists and allowing dissent during decision-making. Improved cooperation between TASU and NRECM can help reduce impacts of warfare on wildlife conservation, while ensuring sustainability of military training on lands critical to biodiversity conservation.

Climate BufferNet is an educational, visual simulation designed to engage higher education students in the Midwestern United States with ideas for improving rural landscape planning outcomes. Past and present social and economic forces shaping the midwestern agricultural landscape have fundamentally transformed its natural systems, impacting food security, biodiversity, and community and ecosystem resilience to climate change. However, the lack of specific knowledge concerning these socioecological and economic forces and their feedback loops constitutes an information barrier to stakeholders new to the decision-making frameworks that shape this complex socioagricultural landscape. This article presents a serious socioecological gaming simulation case study as a framework for familiarizing landscape architecture students with the complex interactive characteristics of these systems. The Climate BufferNet study immersed students in an interactive, co-learning visual media environment that confronted them with real-world challenges of balancing economic priorities with the degraded ecological feedback loops now prevalent in this multifunctional landscape. The results of student evaluations from initial playtesting, presented here, revealed that the simulation accurately demonstrates the difficulty in balancing environmental and economic goals. Further, qualitative coding of student responses shows that players were using the simulation to actively experiment with spatial configurations of conservation practices and decipher rules for targeting their actions. The results of these initial pilot tests, documented here, demonstrate both the potential for engaging landscape architects in rural landscape planning and the need for greater attention to the complexities of environmental and economic tensions between biodiversity, climate change, and ecosystem services.

Achieving ambitious goals to conserve at least 30% of U.S. lands and waters by 2030 ("30 × 30") will require a multiscale baseline understanding of current protections, key decisionmakers, and policy tools for moving forward. To help conservationists and decisionmakers support the science‐based call to address the biodiversity and climate crises, we analyze the current spatial patterns of biodiversity and carbon in the United States relative to protected areas and present a typology for classifying land contributions toward the 30 × 30 goals. Analyses demonstrate that 30% is achievable nationally, but spatial heterogeneity highlights the need for tailored approaches from a mix of authorities at federal, regional, and state scales. Current land protections rarely overlap with areas essential for conserving imperiled species biodiversity and mitigating climate change. One‐fifth of unprotected biodiversity hotspots and over 8% carbon‐rich areas face a higher risk of land conversion by 2050. In contrast, 3.6% of key biodiversity areas and 15.6% of carbon‐rich areas may experience higher climate exposure. Policy considerations for making practical, substantive progress toward ecologically meaningful achievement of 30 × 30 goal include the need for significant investments in public and private lands conservation.

Negotiations for a new international legally binding instrument under the United Nations Convention on the Law of the Sea for the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction (ABNJ) have commenced. For the new agreement to be fair and effective, it is vital that all States are able to participate in the long-term sustainable use and conservation of the ocean beyond national jurisdiction. This includes participation in marine scientific research and the utilization of marine genetic resources (MGR) through subsequent innovation processes. Open access to MGR, such as data, coupled with capacity building, can promote the equitable sharing of benefits associated with MGR. In this paper, it is hypothesized that an 'inclusive innovation' approach may facilitate participation and promote enhanced engagement in the conservation and sustainable use of biodiversity beyond national jurisdiction. A number of existing genetic resource initiatives provide examples of efforts to foster inclusivity in the innovation process, including BioBricks, Open Source Drug Discovery, GenBank and the Global Genome Biodiversity Network. An analysis of these examples enables clear identification of common elements that are adopted by such initiatives, whereby inclusive innovation either develops naturally or is promoted actively through measures for open access, capacity building, and collaboration. By empowering more States and stakeholders to participate in research and innovation processes, global potential in terms of enhanced scientific knowledge and opportunities associated with biodiversity of ABNJ can be promoted and the overall objective of the conservation and sustainable use can be best pursued.

Beef production is a major driver of biodiversity loss and greenhouse gas emissions globally, and multiple studies recommend reducing beef production and consumption. Although there have been significant efforts from the biodiversity conservation sector toward reducing beef‐production impacts, there has been comparatively much less engagement in reducing beef consumption. As a first step to address this gap and identify leverage points, we conducted a policy Delphi expert elicitation. We asked 16 multidisciplinary experts from research and practitioner backgrounds to propose interventions for reducing beef consumption in the United States. Experts generated and critiqued 20 interventions, creating a qualitative dataset that was thematically analyzed to allow the interventions to be prioritized. Effective, feasible interventions included changing perceived social norms, targeting food providers, and increasing the availability and quality of beef alternatives. This work introduces a conservation research agenda for reducing beef consumption and explores a structured process for prioritizing behavioral interventions. [ABSTRACT FROM AUTHOR]

Using the US Agency for International Development's environmental program in Madagascar as a lens, I offer a historically grounded, relational, and multi‐sited methodology for understanding the transnational processes that constitute political forests in the contemporary era. I argue that neoliberal reforms conditioned the emergence of a public–private–non‐profit alliance, which promoted biodiversity conservation as a US foreign aid priority. As these reforms weakened state capacity and liberalised economies, the downsized Madagascar and US governments became reliant on conservation actors to mobilise political support for their programs. This reinforced the need to maintain strategic relationships with capital‐city actors, undermining prior efforts to devolve forest management to local communities. By isolating deforestation as a peasant problem "over there" and by expanding protected areas to meet global biodiversity targets, the conservation alliance created an avenue to be green that did not threaten extractive industries or key constituents. In this manner, saving the environment via protected areas expansion offered politicians a pathway through the inherent contradictions of green neoliberalism. [ABSTRACT FROM AUTHOR]

Protected areas represent a key strategy to conserve biodiversity. However, human land use and other impacts outside protected areas boundaries significantly influence species and ecosystems within protected areas. Therefore, identifying and delineating important lands surrounding protected areas may be critical to developing conservation strategies to sustain biodiversity. Here, we identify greater ecosystems of protected areas in the contiguous United States by delineating permeable wildlands located adjacent to protected area borders using the global human footprint map as the basis for estimating permeability. We evaluated how elevating the conservation status of greater ecosystems could help achieve aspirational targets for protecting additional terrestrial land area while better representing ecological diversity. We then assessed the feasibility of elevating conservation in greater ecosystems by quantifying the composition of land ownership and existing conservation status. Greater ecosystems of different protected areas often occur as large complexes that could be used to manage protected areas and monitor their status under regional conservation strategies. Elevating the conservation status of greater ecosystems could aid in achieving international targets while increasing the representation of vegetative types within conservation reserves. The most connected and permeable lands surrounding protected areas are dominated by public land (managed by the U.S. federal and state governments), though the amount of public land within greater ecosystems decreased with distance from protected areas. Public lands may provide opportunities to elevate the conservation status of greater ecosystems surrounding protected areas through policy and management changes. We focused on the contiguous United States, but our methods could be applied globally (which we demonstrate). To achieve bold international conservation goals, identifying the greater ecosystems around protected areas and developing conservation strategies of their landscape context will ultimately benefit species and ecosystems in protected areas.

Import of wood pellets to the EU from the southeastern United States has increased almost ten‐fold over the past seven years, driven largely by mandates under the Renewable Energy Directive. While the displacement of fossil fuels with biomass can offer significant energy diversity and climate benefits, these must be balanced against the potential detriment from unsustainable extraction of biomass resources. This study projects the scale of the sustainable biomass resource base in the US southeast through 2030 under various scenarios of industry development and domestic market dynamics. We characterise this resource base at the county level, disaggregating it by material type and spatially constraining it to ensure biodiversity conservation. Our analysis shows that there could be as much as 70 million green metric tons of sustainable export potential from the US Southeast in 2030. However, we also show the extent to which sustainable sourcing criteria applied only to EU biomass energy imports could create leakage across biomass markets, erasing gains from any sustainability mandate. This leakage risk was fairly consistent across our study scenarios and time periods, ranging from 50 to over 63 million green tons of biomass per year. Meaningful biodiversity protections can only be achieved if sustainability criteria for biomass import to the EU are combined with more comprehensive support for sustainable sourcing across biomass industries in exporting regions. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd [ABSTRACT FROM AUTHOR]

The ability to respond to the challenges posed by climate change depends on the adaptive capacities of social and ecological systems. However, the term adaptive capacity is ill defined, and applications often ignore social dimensions. Furthermore, the dominant frameworks conceptualizing adaptive capacity terminate with a vulnerability assessment, without considering how such assessments help inform decisions to undertake adaptation actions. We propose a framework that links social and ecological adaptive capacity to conservation decisions. We illustrate our framework in the context of the Sky Islands ecoregion of the southwestern United States. Supporting a transdisciplinary approach, we outline four recommendations for incorporating social and ecological adaptive capacity into adaptation decisions that include convening key actors, the coproduction of science, and ultimately providing a means for decision-makers to learn from adaptation efforts. These measures to better define and leverage social and ecological adaptive capacity will support conservation decision-making in a world of rapid socioecological change. [ABSTRACT FROM AUTHOR]

Monarch butterflies ( Danaus plexippus), other pollinators, and Greater Sage-Grouse ( Centrocercus urophasianus) are currently the focus of increased conservation efforts. Federal attention on these fauna is encouraging land managers to develop conservation strategies, often without corresponding financial resources. This could foster a myopic approach when allocating resources and setting restoration priorities, and at best, allow for inefficiencies in the usage of land management resources, or, at worst, pit one species (or suite of species, e.g., pollinators) against another (e.g., sage-grouse). Instead, investing holistically by linking conservation of these fauna may provide improved leverage of available resources and more benefit to the landscape. Fortunately, on the western US rangelands, these fauna can all benefit from restoration that increases the abundance and diversity of forbs. Establishing high density islands of outplanted forb seedlings may be a way to expedite restoration. Managers establishing forbs for pollinators (including monarchs) would further increase food availability for greater sage-grouse and vice versa. Adding milkweeds ( Asclepias spp.) in appropriate areas to forb mixtures for restoration is warranted because they are excellent nectar sources for pollinators in general and the sole host for monarch larvae in particular. Here, we provide an overview of why forb species are keystone for monarch butterflies, other pollinators, and Greater Sage-Grouse and how seeding and outplanting seedlings of specific forbs are critical to restoration efforts.

The liberalization of marijuana policies, including the legalization of medical and recreational marijuana, is sweeping the United States and other countries. Marijuana cultivation can have significant negative collateral effects on the environment that are often unknown or overlooked. Focusing on the state of California, where by some estimates 60%-70% of the marijuana consumed in the United States is grown, we argue that (a) the environmental harm caused by marijuana cultivation merits a direct policy response, (b) current approaches to governing the environmental effects are inadequate, and (c) neglecting discussion of the environmental impacts of cultivation when shaping future marijuana use and possession policies represents a missed opportunity to reduce, regulate, and mitigate environmental harm.

The article looks at the temperate prairie region of the eastern United States, offering a geographic description of its scope and vegetation at the time of the arrival of Europeans, the 17th and 18th centuries, based on historical sources. Topics include descriptions of meadows and grasslands and maps from the period, and sources include a survey by Geographer of the U.S. Thomas Hutchins. The value of such information in the context of the preservation of biological diversity is cited.

In the face of global environmental change, the importance of protected areas in biological management and conservation is expected to grow. Birds have played an important role as biological indicators of the effectiveness of protected areas, but with little consideration given to where species occur outside the breeding season. We estimated weekly probability of occurrence for 308 bird species throughout the year within protected areas in the western contiguous USA using eBird occurrence data for the combined period 2004 to 2011. We classified species based on their annual patterns of occurrence on lands having intermediate conservation mandates (GAP status 2 and 3) administered by the Bureau of Land Management (BLM) and the United States Forest Service (USFS). We identified species having consistent annual association with one agency, and species whose associations across the annual cycle switched between agencies. BLM and USFS GAP status 2 and 3 lands contained low to moderate proportions of species occurrences, with proportions highest for species that occurred year-round or only during the summer. We identified two groups of species whose annual movements resulted in changes in stewardship responsibilities: (1) year round species that occurred on USFS lands during the breeding season and BLM lands during the nonbreeding season; and (2) summer species that occurred on USFS lands during the breeding season and BLM lands during spring and autumn migration. Species that switched agencies had broad distributions, bred on high-elevation USFS lands, were not more likely to be identified as species of special management concern, and migrated short (year-round species) to long distances (summer species). our findings suggest cooperative efforts that address the requirements of short-distance migratory species on GAP status 2 lands (n = 20 species) and GAP status 3 lands (n = 24) and long-distance migratory species on GAP status 2 lands (n = 9) would likely benefit their populations. Such efforts may prove especially relevant for species whose seasonal movements result in associations with different environments containing contrasting global change processes and management mandates.

Management for biodiversity and other ecosystem services from North America's rangelands has received increasing attention as recognition of the societal value of those services and payment mechanisms for them have grown. This, combined with adverse effects of livestock management on North American rangeland biodiversity and predictions of a warmer and drier climate reducing rangeland productivity, has led some rangeland scientists to call for a paradigm shift from utilitarian-driven management to biodiversity conservation management. A challenge for rangeland science is to describe management changes required for this shift and to elucidate consequent ecological and economic tradeoffs. On the basis of two criteria, direct alteration of biodiversity and alteration of one or more drivers of biodiversity, a framework of ten ecological conditions is proposed for making the transition from livestock-centered management toward biodiversity-centered management on Great Plains rangelands: (1) composition and productivity of plant communities; (2) herbivory patterns; (3) fire regimes; (4) habitat contiguity; (5) stream hydrology; (6) temporal ecological variability; (7) herbivorous mammal communities; (8) fate of ungulate production; (9) apex predators; and (10) size of management units. Reflecting trends in rangelands elsewhere around the world, a shift toward management for biodiversity on the Great Plains may be facilitated by changes underway in land ownership and by a potentially increasing number of landowners for whom livestock production is of secondary importance to lifestyle and natural amenity benefits from the land.

Many protected areas may not be adequately safeguarding biodiversity from human activities on surrounding lands and global change. The magnitude of such change agents and the sensitivity of ecosystems to these agents vary among protected areas. Thus, there is a need to assess vulnerability across networks of protected areas to determine those most at risk and to lay the basis for developing effective adaptation strategies. We conducted an assessment of exposure of U.S. National Parks to climate and land use change and consequences for vegetation communities. We first defined park protected-area centered ecosystems (PACEs) based on ecological principles. We then drew on existing land use, invasive species, climate, and biome data sets and models to quantify exposure of PACEs from 1900 through 2100. Most PACEs experienced substantial change over the 20th century (>740% average increase in housing density since 1940, 13% of vascular plants are presently nonnative, temperature increase of 1°C/100 yr since 1895 in 80% of PACEs), and projections suggest that many of these trends will continue at similar or increasingly greater rates (25℃ increase in housing density by 2100, temperature increase of 2.5C-4.5°C/100 yr, 30% of PACE areas may lose their current biomes by 2030). In the coming century, housing densities are projected to increase in PACEs at about 82% of the rate of since 1940. The rate of climate warming in the coming century is projected to be 2.5-5.8 times higher than that measured in the past century. Underlying these averages, exposure of individual park PACEs to change agents differ in important ways. For example, parks such as Great Smoky Mountains exhibit high land use and low climate exposure, others such as Great Sand Dunes exhibit low land use and high climate exposure, and a few such as Point Reyes exhibit high exposure on both axes. The cumulative and synergistic effects of such changes in land use, invasives, and climate are expected to dramatically impact ecosystem function and biodiversity in national parks. These results are foundational to developing effective adaptation strategies and suggest policies to better safeguard parks under broad-scale environmental change. [ABSTRACT FROM AUTHOR]

For more than 100 years, the US government has conducted lethal control of native wildlife, to benefit livestock producers and to enhance game populations, especially in the western states. Since 2000, Wildlife Services (WS), an agency of the US Department of Agriculture, has killed 2 million native mammals, predominantly 20 species of carnivores, beavers, and several species of ground-dwelling squirrels, but also many nontarget species. Many are important species in their native ecosystems (e.g., ecosystem engineers such as prairie dogs and beavers, and apex predators such as gray wolves). Reducing their populations, locally or globally, risks cascading negative consequences including impoverishment of biodiversity, loss of resilience to biotic invasions, destabilization of populations at lower trophic levels, and loss of many ecosystem services that benefit human society directly and indirectly. Lethal predator control is not effective at reducing depredation in the long term. Instead, we recommend that WS and its government partners involved in wildlife conflict management emphasize training livestock producers in methods of nonlethal control, with sparing use of lethal control by methods that are species-specific, and cease all lethal control in federal wilderness areas and for the purpose of enhancing populations of common game species.

If conservation of biodiversity is the goal, then the protected areas network of the continental US may be one of our best conservation tools for safeguarding ecological systems (i.e., vegetation communities). We evaluated representation of ecological systems in the current protected areas network and found insufficient representation at three vegetation community levels within lower elevations and moderate to high productivity soils. We used national-level data for ecological systems and a protected areas database to explore alternative ways we might be able to increase representation of ecological systems within the continental US. By following one or more of these alternatives it may be possible to increase the representation of ecological systems in the protected areas network both quantitatively (from 10% up to 39%) and geographically and come closer to meeting the suggested Convention on Biological Diversity target of 17% for terrestrial areas. We used the Landscape Conservation Cooperative framework for regional analysis and found that increased conservation on some private and public lands may be important to the conservation of ecological systems in Western US, while increased public-private partnerships may be important in the conservation of ecological systems in Eastern US. We have not assessed the pros and cons of following the national or regional alternatives, but rather present them as possibilities that may be considered and evaluated as decisions are made to increase the representation of ecological systems in the protected areas network across their range of ecological, geographical, and geophysical occurrence in the continental US into the future.

In Europe and North America, there is growing concern that biodiversity declines associated with agricultural intensification will adversely impact the functioning and sustainability of agricultural ecosystems. Enhancing habitat heterogeneity in agricultural landscapes promotes biodiversity and, whilst erecting fences adjacent to watercourses is widely advocated as a means of mitigating diffuse pollution, associated biodiversity benefits have been largely overlooked., A range of riparian margins and their adjacent grassland fields were investigated to determine the effects of riparian management on the diversity and functional structure of carabid assemblages. Carabid assemblages of fields and open margins (i.e. unfenced watercourses) were more diverse and species rich than those of fenced margins., The functional structure of carabid assemblages in fenced margins differed from grassland fields and open margins. This disparity was greater in wide margins (i.e. fences erected over 5·4 m from watercourses) than narrow margins (i.e. fences erected within 2·6 m of watercourses). Wide margins had the highest relative proportions of carabids which had pushing body forms, were flightless, very small in size and Collembola specialists. During early summer, wide margins also had the highest proportion of carabids that overwinter as adults., The taxonomic and functional structure of carabid assemblages was more sensitive for detecting impacts of agricultural management than measurements of diversity. It is likely that this also applies to other taxa, thus emphasising the need to consider a wide range of assemblage attributes when investigating agricultural impacts on biodiversity., Synthesis and applications. Fenced riparian margins, particularly those over 5·4 m wide, harbour carabids with poor dispersal ability which are vulnerable to habitat fragmentation. While lack of management benefits sedentary species, a wider range of taxa (e.g. pollinators, foraging birds and flowering plants) are enhanced by management to obtain a more open vegetation structure (e.g. restricted grazing or mowing). It is important that management practices are implemented at a sufficiently fine spatial scale to allow recolonisation of species with restricted dispersal from adjacent undisturbed habitats. Wide riparian margins have the potential to enhance taxonomic and functional diversity at the landscape scale. Management actions must, however, be carefully balanced to ensure that they promote a wide range of taxa without unduly interfering with the margin's ability to mitigate diffuse pollution.

Background: Private land conservation is an essential strategy for biodiversity protection in the USA, where half of the federally listed species have at least 80% of their habitat on private lands. We investigated the alignment between private land protection conducted by the world's largest land trust (The Nature Conservancy) and the science driven identification of priority areas for conservation. This represents the first quantitative assessment of the influence of defining priority areas on the land acquisitions of a conservation non-governmental organization (NGO). Methodology/Principal Findings: The lands acquired by The Nature Conservancy (TNC) were analyzed using GIS to determine to what extent they were in areas defined as priorities for conservation. The spatial analysis of TNC lands was broken up into land known to be acquired in the last five years, five to ten years ago, prior to ten years ago, and anytime during the last sixty years (including previous sets of data plus acquisitions lacking a date). For the entire history of TNC the proportion of TNC lands within the priority areas was 74%. Prior to 10 years ago it was 80%, 5-10 years ago it was 76%, and in the last five years it was 81%. Conservation easements were found to have lower alignment with priority areas (64%) than outright fee simple acquisitions (86%). Conclusions/Significance: Overall the location of lands acquired was found to be well aligned with the priority areas. Since there was comparable alignment in lands acquired before and after formalized conservation planning had been implemented as a standard operating procedure, this analysis did not find evidence that defining priority areas has influenced land acquisition decisions.

For many citizens and policymakers, the empirical relationship between economic growth and biodiversity conservation has not been sufficiently established for purposes of identifying the types of economic policies amenable to biodiversity conservation. Some think economic growth conflicts with biodiversity conservation; others think economic growth conduces biodiversity conservation. With panel data from 1997-2011, encompassing US continental states, we developed a series of statistical models to investigate the relationships among species endangerment, human population, and economic growth as indicated by GDP and per capita GDP. Species endangerment is highly correlated with population and GDP, and per capita GDP is a significant regressor of species endangerment. Across US continental states, competitive exclusion of non-human species occurs via human economic growth and population growth. [ABSTRACT FROM AUTHOR]

Forest plantations support several ecosystem services including biodiversity conservation. Establishment of a forest biomass-based industry could significantly change the age structure of forest plantations located in its vicinity and thus, could lead to a possible loss of biodiversity. Therefore, this study assesses spatiotemporal impacts of a forest biomass-based power plant on the age structure of surrounding forest plantations at landscape level. A cellular automata approach was adopted and interactions between economic objectives of forest landowners and a power plant owner punctuated by forest growth and management characteristics were considered. These spatiotemporal impacts were jointly assessed for four separate scenarios and four different power plant capacities using appropriate landscape-level indices. Slash pine ( P inus elliotti L.) was selected as a representative species. Results indicate that the age structure of surrounding forest plantations continuously fluctuates with respect to each year of power plant operation. However, the age structure, once disturbed, never becomes comparable to the original age structure. We also found that the mature plantations were harvested during early years of power plant operation and were never observed again for the remaining years of power plant operation. This was particularly true for high capacity power plants. Similarly, high value of selected spatial index at the end of power plant life for a high capacity power plant relative to the original low value of the same index indicates aggregation of remaining plantation ages at landscape level. Establishment of low capacity forest biomass-based power plants and adoption of an integrated regional level planning approach could help in maintaining original age structure characteristics of surrounding forest plantations to a large extent. This might help in sustaining various ecosystem services including biodiversity conservation obtained from forest plantations in a long run. [ABSTRACT FROM AUTHOR]

Nonprofit organizations play a critical role in efforts to conserve biodiversity. Their success in this regard will be determined in part by how effectively individual nonprofits and the sector as a whole are structured. One of the most fundamental questions about an organization's structure is how large it should be, with the logical counterpart being how concentrated the whole sector should be. We review empirical patterns in the size, concentration, and growth of over 1700 biodiversity-conservation nonprofits registered for tax purposes in the United States within the context of relevant economic theory. Conservation-nonprofit sizes vary by six to seven orders of magnitude and are positively skewed. Larger nonprofits access more revenue streams and hold more of their assets in land and buildings than smaller or midsized nonprofits do. The size of conservation nonprofits varies with the ecological focus of the organization, but the growth rates of nonprofits do not. [ABSTRACT FROM AUTHOR]

For more than a decade, the U.S. government has promoted integrated pest management (IPM) to advance sustainable agriculture. However, the usefulness of this practice has been questioned because of lagging implementation. There are at least two plausible rationales for the slow implementation: (1) growers are not adopting IPM-for whatever reason-and (2) current assessment methods are inadequate at assessing IPM implementation. Our research addresses the second plausibility. We suggest that the traditional approach to measuring IPM implementation on its own fails to assess the distinct, biologically hierarchical components of IPM, and instead aggregates growers' management practices into an overall adoption score. Knowledge of these distinct components and the extent to which they are implemented can inform government officials as to how they should develop targeted assistance programs to encourage broader IPM use. We address these concerns by assessing the components of IPM adoption and comparing our method to the traditional approach alone. Our results indicate that there are four distinct components of adoption-weed, insect, general, and ecosystem management-and that growers implement the first two components significantly more often than the latter two. These findings suggest that using a more nuanced measure to assess IPM adoption that expands on the traditional approach, allows for a better understanding of the degree of IPM implementation.

The US. Forest Service and other federal agencies often face tough choices about how to reconcile competing congressional mandates for multiple use and environmental protection of public lands. The balance they achieve will determine the long-term health of many of our nation's ecosystems and the sustainability of the invaluable services they perform. Providing agency scientists and managers with the flexibility and systemic incentives to intelligently address the questions they face is therefore crucial. As the Forest Service actively reworks its planning rule, past failures provide valuable lessons about where improvements to biodiversity protections are needed and what forms they should take. The 2010 decision by the Ninth Circuit in Native Ecosystems Council v. Tidwell highlights some of the problems inherent in the current system, including a management indicator species mandate that lacks scientific support, front-loaded environmental analysis which fails to facilitate learning and perpetuates unsuccessful practices, and a lack of transparency in Forest Service decision making that can render the National Forest Management Act's biodiversity mandate judicially unenforceable. The new planning rule should address these deficiencies with strong requirements for native species viability, use of the best available science (including full disclosure of uncertainties), and a truly adaptive management framework based on ongoing monitoring, frequent reevaluation, and changed practices when failures occur. While the draft rule issued in Februaiy 2011 takes tentative steps in this direction, it does not achieve the meaningful, enforceable changes needed. [ABSTRACT FROM AUTHOR]

Restoration and management activities targeted at recovering biodiversity can lead to unexpected results. In part, this is due to a lack of understanding of how site-level characteristics, landscape factors, and land-use history interact with restoration and management practices to determine patterns of diversity. For plants, such factors may be particularly important since plant populations often exhibit lagged responses to habitat loss and degradation. Here, we assess the importance of site-level, landscape, and historical effects for understory plant species richness and composition across a set of 40 longleaf pine Pinus palustris woodlands undergoing restoration for the federally endangered red-cockaded woodpecker in the southeastern United States. Land-use history had an overarching effect on richness and composition. Relative to historically forested sites, sites with agricultural histories (i.e. former pastures or cultivated fields) supported lower species richness and an altered species composition due to fewer upland longleaf pine woodland community members. Landscape effects did not influence the total number of species in either historically forested or post-agricultural sites; however, understory species composition was affected by historical connectivity, but only for post-agricultural sites. The influences of management and restoration activities were only apparent once land-use history was accounted for. Prescribed burning and mechanical overstory thinning were key drivers of understory composition and promoted understory richness in post-agricultural sites. In historically forested sites these activities had no impact on richness and only prescribed fire influenced composition. Our findings reveal complex interplays between site-level, landscape, and historical effects, suggest fundamentally different controls over plant communities in longleaf pine woodlands with varying land-use history, and underscore the importance of considering land-use history and landscape effects during restoration.

The article reports on how the U.S. can save the fish stocks in Antarctica. It mentions that the change rate in fishing technology and rules are large, and the competition among fishing groups' interests led a split stakeholder community. It notes that lawmakers have raised network international agreements and tools to protect the biodiversity of the continent. It adds that its treatment as a global commons has brought a trend of discovery, exploitation and collapse in natural resources.

The article focuses on the importance of scanning for solutions to environmental approach to conserve biological diversity in the U.S. It states that the approach can give people a sense of the quality and quantity of solutions and the conservation priorities and to provide the groundwork for assessing the solution's effectiveness. It mentions that three main threat to test the practicality and usefulness of solution scanning including the creation of oceanic dead zones.
