This paper presents a comprehensive forest mapping system using a customized drone payload equipped with Light Detection and Ranging (LiDAR), cameras, a Global Navigation Satellite System (GNSS), and Inertial Measurement Unit (IMU) sensors. The goal is to develop an efficient solution for collecting accurate forest data in dynamic environments and to highlight potential wildfire regions of interest to support precise forest management and conservation on the ground. Our paper provides a detailed description of the hardware and software components of the system, covering sensor synchronization, data acquisition, and processing. The overall system implements simultaneous localization and mapping (SLAM) techniques, particularly Fast LiDAR Inertial Odometry with Scan Context (FASTLIO-SC), and LiDAR Inertial Odometry Smoothing and Mapping (LIOSAM), for accurate odometry estimation and map generation. We also integrate a fuel mapping representation based on one of the models, used by the United States Secretary of Agriculture (USDA) to classify fire behavior, into the system using semantic segmentation, LiDAR camera registration, and odometry as inputs. Real-time representation of fuel properties is achieved through a lightweight map data structure at 4 Hz. The research results demonstrate the effectiveness and reliability of the proposed system and show that it can provide accurate forest data collection, accurate pose estimation, and comprehensive fuel mapping with precision values for the main segmented classes above 85%. Qualitative evaluations suggest the system's capabilities and highlight its potential to improve forest management and conservation efforts. In summary, this study presents a versatile forest mapping system that provides accurate forest data for effective management. [ABSTRACT FROM AUTHOR]

Abstract Aim The United States (US) and other affluent countries consume vast quantities of global natural resources, but contribute proportionately less to the extraction of many raw materials. This imbalance is due, in part, to domestic policies intended to protect the environment. Ironically, developed nations are often better equipped to extract resources in an environmentally prudent manner than the major suppliers. Thus, although citizens of affluent countries may imagine that preservationist domestic policies are conserving resources and protecting nature, heavy consumption rates necessitate resource extraction elsewhere and oftentimes under weak environmental oversight. A major consequence of this ‘illusion of natural resource preservation’ is greater global environmental degradation than would arise if consumption were reduced and a large portion of production was shared by affluent countries. This paper considers some implications of the consumption, management and conservation of forests and wood at a local and global scale. Location We focus on Massachusetts, the eighth most forested state in the USA (by area), the third most densely populated, and an affluent region with consumption rates that are among the highest in the country. Methods Estimates of wood production and consumption are generated, and comparisons are made with other commonly used materials (e.g. steel, concrete, aluminium). Results A comparison of the feasibility and environmental impact of various strategies for dealing with rising wood demand suggests that the US should strive to: (1) reduce per capita consumption of wood and its substitutes, (2) recycle forest products more effectively, (3) protect extensive areas of intensively managed and unmanaged forests and (4) promote sound forest management where the environmental consequences are mild. Forestry and the sustainable generation of wood in Massachusetts would allow preservation of primary forests elsewhere in... [ABSTRACT FROM AUTHOR]

The goal of this paper is to describe recent attempts to define the stewardship concept and to translate it into action on the ground. The focus is on national forest lands and the unique challenges federal land managers face in working with the public to implement a concept that has different meanings to a variety of stakeholders. Stewardship requires more flexibility than is often found under existing administrative authorities. Large, bureaucratic agencies face many barriers in applying creative and innovative solutions to existing problems, not the least of which are internal and external reward structures. While there exist some authorities that allow for the creative testing of stewardship contracting projects on the ground, a number of challenges remain. Two significant ones are: (1) the need for a clearer, consistent understanding (by both Forest Service employees and constituents) of the authorities that can be used to test stewardship concepts; and (2) a more broad-based agreement on the desired outcome of stewardship projects. Given the current lack of understanding and agreement on how to implement stewardship concepts, the most effective means of moving the issue forward will be to apply innovative tests of contracting methods under current or new temporary authorities. These tests should be designed, implemented, monitored, and evaluated using broad-based, inclusive, on-the-ground coalitions that create effective ties and linkages between local and national levels.

In their 1992 paper, Schlager and Ostrom presented a property rights framework characterized by nested, cumulative attributes. It has become arguably the most ubiquitous framework for analysis of natural resources and property rights. We revisit their contribution and discuss how the framework could evolve to address increasingly complex situations, with particular attention to institutional change. We devote increased attention to duties and liabilities associated with right allocation, tying the framework to a broader property rights literature. We conclude with an application to reducing emissions from deforestation and forest degradation (REDD+), illustrating how revisions to the framework facilitate contemporary institutional analysis.

Geographically explicit analysis tools are needed to assess forest health indicators that are measured over large regions. Spatial scan statistics can be used to detect spatial or spatiotemporal clusters of forests representing hotspots of extreme indicator values. This paper demonstrates the approach through analyses of forest fragmentation indicators in the southeastern United States and insect and pathogen indicators in the Pacific Northwest United States. The scan statistic detected four spatial clusters of fragmented forest including a hotspot in the Piedmont and Coastal Plain region. Three recurring clusters of insect and pathogen occurrence were found in the Pacific Northwest. Spatial scan statistics are a powerful new tool that can be used to identify potential forest health problems. [ABSTRACT FROM AUTHOR]

Forests are currently a substantial carbon sink globally. Many climate change mitigation strategies leverage forest preservation and expansion, but rely on forests storing carbon for decades to centuries. Yet climate‐driven disturbances pose critical risks to the long‐term stability of forest carbon. We quantify the climate drivers that influence wildfire and climate stress‐driven tree mortality, including a separate insect‐driven tree mortality, for the contiguous United States for current (1984–2018) and project these future disturbance risks over the 21st century. We find that current risks are widespread and projected to increase across different emissions scenarios by a factor of >4 for fire and >1.3 for climate‐stress mortality. These forest disturbance risks highlight pervasive climate‐sensitive disturbance impacts on US forests and raise questions about the risk management approach taken by forest carbon offset policies. Our results provide US‐wide risk maps of key climate‐sensitive disturbances for improving carbon cycle modeling, conservation and climate policy. [ABSTRACT FROM AUTHOR]

Understanding the dynamics behind forest transitions, i.e., shifts from deforestation to forest recovery, is crucial for forest conservation and climate-change mitigation i.e., carbon (C) sequestration. We investigated the drivers of the forest transition in the United States, which was characterized by forest thickening despite surges in industrial wood extraction. We employ the concepts of Human Appropriation of Net Primary Productivity (HANPP) and Material and Energy Flow Analysis (MEFA) to quantitatively assess changes in major provisioning ecosystem services demanded from forests, i.e., industrial wood (comprising biomass used in products such as paper and pulp), grazing, and fuelwood, and analyse substitution processes from 1870-2012 at regional, sectoral, and national scales. The share of industrial wood in total annual forest biomass harvest increased from 23% to 84% over the time-period, while fuelwood and biomass grazed declined from 63% to 13%, and 14% to 3%, respectively. Reductions in demand for fuelwood and biomass grazed were enabled by shifts in feed and energy sources, consequently allowing for increases in both livestock numbers and energy use. Feed crops increased six-fold, alleviating grazing pressure on forest ecosystems, particularly in the Eastern states. Fossil fuels replaced fuelwood, especially in the residential sector. Between 1900-2012 the final energy mix increased seventeen-fold. Thus, the increase in biomass C stocks in U.S. forests was connected to substitution of forest ecosystem services with fossil fuel-based production systems, and with manifold increases in societal resource use and C dynamics. Such shifts need to be considered when assessing the positive environmental effects of forest transitions. [Display omitted] [ABSTRACT FROM AUTHOR]

Environmental regulations and public financial assistance programs are the typical "sticks" and "carrots" facing non-industrial private forest (NIPF) landowners in the U.S. this paper presents a theoretical framework and empirical evidence on the impacts of the Endangered Species Act and public financial assistance programs—cost-share programs and a tax incentive program—on reforestation investment behavior. The results indicate that NIPF landowners' reforestation investments are influenced negatively by environmental regulations and positively by public financial assistance programs. The results imply that both sticks and carrots can be used simultaneously to influence NIPF landowners' reforestation behavior. [ABSTRACT FROM AUTHOR]

The article suggests that the high cost of timber and newsprint paper can be attributed to decimation of the forests of the East. According to U.S. Secretary of Agriculture Edwin Thomas Meredith, three fifths of the original timber of the country is gone and that consumption has exceeded supply. Meredith is supporting the position taken by the forest service that the basic need is a national policy of reforestation.

Carbon-based payments for ecosystem services solely consider afforestation and reforestation to assess sequestration. However, political ecology researchers demonstrate that tropical forests are complex socioecological systems where humans and institutions play an integral role in shaping landscapes. The current framing overlooks the net effect of traditional subsistence agriculturalists leaving behind low emission lifestyles, despite the likelihood of a significant increase in per capita emissions over time. In this case study, we use the history of forest use in the Pueblos Mancomunados—a commonwealth of indigenous communities in Oaxaca, Mexico—to explore sequestration through a socioecological systems lens. As negative emissions programs consider afforestation, we triangulated semistructured interviews, an unsupervised GIS classification of land cover, and a review of carbon dioxide emissions to consider out-migration, abandonment, and lifestyle change. We find that communities are struggling to maintain livelihoods as migration to urban centers and the United States continues. Meanwhile, spatial analysis revealed 800 ha of afforestation. Our analysis of out-migration scenarios and per capita emissions changes identified a tipping point in which no net-sequestration would occur from afforestation due to the changing lifestyles of the migrants and recommend improved local development to avoid this form of "leakage" when assessing global carbon stocks.

Landscape context is an important factor in restoration ecology, but the use of landscape context for site prioritization has not been as fully developed. We used morphological image processing to identify candidate ecological restoration areas based on their proximity to existing natural vegetation. We identified 1,102,720 candidate ecological restoration areas across the continental United States. Candidate ecological restoration areas were concentrated in the Great Plains and eastern United States. We populated the database of candidate ecological restoration areas with 17 attributes related to site content and context, including factors such as soil fertility and roads (site content), and number and area of potentially conjoined vegetated regions (site context) to facilitate its use for site prioritization. We demonstrate the utility of the database in the state of North Carolina, U.S.A. for a restoration objective related to restoration of water quality (mandated by the U.S. Clean Water Act), wetlands, and forest. The database will be made publicly available on the U.S. Environmental Protection Agency's EnviroAtlas website () for stakeholders interested in ecological restoration. [ABSTRACT FROM AUTHOR]

In the United States, over 191 million acres of land is managed by the United States Department of Agriculture Forest Service, a federal government agency. In several western U.S. states, organized collaborative groups have become a de facto governance approach to providing sustained input on management decisions on much public land. This is most extensive in Oregon, where at least 25 'forest collaboratives' currently exist. This affords excellent opportunities for studies of many common themes in collaborative governance, including trust, shared values, and perceptions of success. We undertook a statewide survey of participants in Oregon forest collaboratives to examine differences in motivations, perceptions of success, and satisfaction among Forest Service participants ('agency participants'), who made up 31% of the sample, and other respondents ('non-agency') who represent nonfederal agencies, interest groups, citizens, and non-governmental groups. We found that agency participants differed from non-agency participants. They typically had higher annual incomes, and were primarily motivated to participate to build trust. However, a majority of all respondents were similar in not indicating any other social or economic motivations as their primary reason for collaborating. A majority also reported satisfaction with their collaborative-despite not ranking collaborative performance on a number of specific potential outcomes highly. Together, this suggests that collaboration in Oregon is currently perceived as successful despite not achieving many specific outcomes. Yet there were significant differences in socioeconomic status and motivation that could affect the ability of agency and nonagency participants to develop and achieve mutually-desired goals.

The old-growth endemic Imeretian oak [Quercus robur subsp. imeretina (Steven ex Woronow) Menitsky, 1968] is a protected relict Tertiary period tree still preserved in Ajameti Managed Reserve (Republic of Georgia). For a long time, these forests were experienced to the strong anthropogenic influence. The old-age oak trees and the development of root and stem rot have promoted the settlement of great capricorn beetle [Cerambyx cerdo Linnaeus, 1758 (Coleoptera: Cerambycidae)]. Both of species are protected under the EU Habitats Directive and listed in the IUCN Red List of Threatened Species. The investigation of settling degree of C. cerdo was conducted at two areas, Ajameti and Vartsikhe, on the edge and in the middle of oak forests in June and October 2014. On both the areas, the number of trees with fly exit holes of great capricorn beetle was higher on the margin of forests where plantations suffer greater of human impact. The number of fly exit holes of imago is significantly increased due to deterioration of sanitary condition of forests. The measures of management conservation at Ajameti Managed Reserve were proposed. [ABSTRACT FROM AUTHOR]

Climate change is one of several threats that will increase the likelihood that forest tree species could experience population-level extirpation or species-level extinction. Scientists and managers from throughout the United States Forest Service have cooperated to develop a framework for conservation priority-setting assessments of forest tree species. This framework uses trait data and predictions of expected climate change pressure to categorize and prioritize 339 native tree species for conservation, monitoring, management and restoration across all forested lands in the contiguous United States and Alaska. The framework allows for the quantitative grouping of species into vulnerability classes that may require different management and conservation strategies for maintaining the adaptive genetic variation of the species within each group. This categorization is based on risk factors relating to the species' (1) exposure to climate change, (2) sensitivity to climate change, and (3) capacity to adapt to climate change. We used K-means clustering to group species into seven classes based on these three vulnerability dimensions. The most vulnerable class encompassed 35 species with high scores for all three vulnerability dimensions. These will require the most immediate conservation intervention. A group of 43 species had high exposure and sensitivity, probably requiring conservation assistance, while a group of 69 species had high exposure and low adaptive capacity, probably needing close monitoring. This assessment tool should be valuable for scientists and managers determining which species and populations to target for monitoring efforts and for pro-active gene conservation and management activities.

The mesosphytic forests of eastern North America represent a forest region characterized by dramatic 20th century changes in disturbance regimes, notably the exclusion of fire. Tree-ring reconstructions of forest disturbance can inform restoration and management plans by placing these changes into a historical context. This study examined forest disturbance with regard to land use change and drought in the New River Gorge region of West Virginia. I developed a 182-year pitch pine ( Pinus rigida) growth chronology (1833-2014) using samples collected from 33 trees along 2 km of southand southwest-facing slopes at Babcock State Park. Samples cut from fire-scarred pitch and Virginia pine ( Pinus virginiana) were used to generate a fire chronology for the site. Temporal trends in pitch pine growth variability were assessed using regime shift and growth release detection methods. There was no change in pitch pine growth during the transition from the early settlement to industrial era (ca. 1885), while a significant decrease in annual growth variability characterized the post-industrial era (1963-2014). Seventeen fire events were recorded between 1887 and 1968. Growth releases displayed a temporal relationship with fire and there was a strong, but not significant, association between drought and fire years. These results suggest a coupled system in which anthropogenic fires driven by periodic drought maintained pitch pine before and during industrialization. Reintroducing fire to the post-industrial forest may not meet management objectives as decades of fire exclusion have altered forest fuels and species composition such that its effects would be difficult to predict.

Approximately 20 years ago, the preeminent goal for management of the federal forests of the Pacific Northwest shifted suddenly and permanently from sustained timber harvest to conservation of biodiversity and ecological processes, following a series of court cases over protection of species in decline that were associated with old forests. While old growth harvest has largely ceased, some key species are still in decline and forest management has been restricted more than intended. Creation of openings, even those based on disturbance processes, has been especially difficult. Some lessons from this experience include the difficulty of adaptive management, the importance of ecological foundations for management, and the need for stakeholder collaboration. In addition, it is essential to provide society with a vision of ecologically-based forestry, including field demonstrations, and to communicate this approach and its scientific foundation in the popular media.

This study situates environmental discourses and practices within a dialectical framework, identifying how contradictory, double-bind messages can promote 'schizophrenic' environmental meaning systems. I position this study through a qualitative examination of a U.S. state forest conservation education program, where K-12 students take field trips to forests to learn about nature. Adults frame environmental issues within a core stay away-get close double bind, sending conflicting messages to protect and appreciate trees, yet ultimately cut them down for human hyperconsumption. These tug-and-pull, double-bind messages enable what I call ecocultural schizophrenia, a condition that ultimately decreases connectivity and sustainability. Through alternative practices, dialectical thinking is needed to help reject ecocultural double binds and create more sustainable possibilities. [ABSTRACT FROM AUTHOR]

This study focuses on the relationships of watershed runoff with historical land use/land cover ( LULC) and climate trends. Over the 20th Century, LULC in the Southeast United States, particularly the North Carolina Piedmont, has evolved from an agriculture dominated to an extensively forested landscape with more recent localized urbanization. The regrowth of forest has an important influence on the hydrology of the region as it enhances ecosystem interaction with recent climate change. During 1920-2009, the amount of precipitation in some parts of the North Carolina Piedmont forest regrowth area showed increasing trends without corresponding increments in runoff. We employed the Soil and Water Assessment Tool ( SWAT) to backcast long-term hydrologic behavior of watersheds in North Carolina with different LULC conditions: (1) LULC conversion from agricultural to forested area and (2) long-term stable forested area. Comparing U.S. Geological Survey-measured stream discharge with SWAT-simulated stream discharge under the assumption of constant 2006 LULC, we found significant stream discharge underprediction by SWAT in two LULC conversion watersheds during the early simulation period (1920s) with differences gradually decreasing by the mid-1970s. This model bias suggests that forest regrowth on abandoned agricultural land was a key factor contributing to mitigate the impact of increased precipitation on runoff due to increasing water consumption driven by changes in vegetation.

A century ago, the US Congress passed legislation that authorised the Secretary of Agriculture 'to purchase forested, cutover or denuded lands within the watersheds of navigable streams'. Known as the 1911 Weeks Act, the bill had an enormous impact on the newly created national forest system. The purchase authority eventually added nearly 20 million acres to the national forest system east of the Mississippi River but its influence goes far beyond the boundaries of the national forests. In addition, the Weeks Act provided funding and authority for the US Forest Service to enter into cooperative agreements with state and private forest owners, thus extending federal forest conservation practices across the nation. This article traces the events and context surrounding forest management in the US that led to passage of the Act. After decades of efforts, a coalition of public interest and congressional support combined to pass one of the foundational pieces of legislation in American forest management whose influence continues today.

The current conditions of many seasonally dry forests in the western and southern United States, especially those that once experienced low- to moderate-intensity fire regimes, leave them uncharacteristically susceptible to high-severity wildfire. Both prescribed fire and its mechanical surrogates are generally successful in meeting short-term fuel-reduction objectives such that treated stands are more resilient to high-intensity wildfire. Most available evidence suggests that these objectives are typically accomplished with few unintended consequences, since most ecosystem components (vegetation, soils, wildlife, bark beetles, carbon sequestration) exhibit very subtle effects or no measurable effects at all. Although mechanical treatments do not serve as complete surrogates for fire, their application can help mitigate costs and liability in some areas. Desired treatment effects on fire hazards are transient, which indicates that after fuel-reduction management starts, managers need to be persistent with repeated treatment, especially in the faster-growing forests in the southern United States.

Information on the rates, characteristics, and drivers of land-use change are vital for addressing the impacts and feedbacks of change on environmental processes. The U.S. Geological Survey's Land Cover Trends project is conducting a consistent, national analysis of the rates, causes, and consequences of land-use change. In this article we assess change in the Atlantic Coastal Pine Barrens ecoregion from 1973 to 2000. Urban lands expanded by more than 900 square kilometers during the study period. Land-use change in the ecoregion followed the tenets of 'Forest Transition Theory' ( ftt) prior to the study period, but forest lands experienced consistent declines from 1973 to 2000. Increasing government regulation during the study period, consistent with concept of the 'Quiet Revolution' ( qr), mitigated forest loss during the latter half of the study period. Generalized theories, including ftt and the qr, are valuable, but local and regional determinants of comparative land rents ultimately drive land-use change at this scale. [ABSTRACT FROM AUTHOR]

Economic and political realities present challenges for implementing an aggressive climate change abatement program in the United States. A high-efficiency approach will be essential. In this synthesis, we compare carbon budgets and evaluate the carbon-mitigation potential for nine counties in the northeastern United States that represent a range of biophysical, demographic, and socioeconomic conditions. Most counties are net sources of carbon dioxide (CO2) to the atmosphere, with the exception of rural forested counties, in which sequestration in vegetation and soils exceed emissions. Protecting forests will ensure that the region's largest CO2 sink does not become a source of emissions. For rural counties, afforestation, sustainable fuelwood harvest for bioenergy, and utility-scale wind power could provide the largest and most cost-effective mitigation opportunities among those evaluated. For urban and suburban counties, energy-efficiency measures and energy-saving technologies would be most cost effective. Through the implementation of locally tailored management and technology options, large reductions in CO2 emissions could be achieved at relatively low costs. [ABSTRACT FROM AUTHOR]

Large-scale sell-offs of industrial timberlands in the United States have prompted public and private investments in a new class of "working forest" land deals, notable for their large size and complex divisions of property rights. These transactions have been pitched as "win-win-win" deals that provide social, economic, and ecological benefits. Despite hundreds of millions of dollars invested in these transactions, we found a paucity of evidence that their supposed benefits are being realized. Monitoring programs necessary to gather such evidence tend to be underfunded, short term, and focused on a limited set of indicators. The few projects with more comprehensive monitoring programs had long-term funding sources, formal mechanisms for incorporating data into subsequent management decisions, and combined multidisciplinary monitoring techniques. We propose that a relatively modest allocation of funds to monitoring could help assess—and hopefully improve—the effectiveness of current and future transactions, to see if the promise of "win-win-win" is actually delivered.
