All eight pangolin species are threatened with extinction, largely through demand for their products including scales, meat and body parts. The demand for pangolin scales has gained attention from many conservation groups due to the large volumes involved in illegal trade. Market demand in China is one of the major drivers for international illegal trade according to confiscation reports, and many conservation interventions have been attempted to reduce this demand. The Traditional Chinese Medicine (TCM) community plays a key role in regulating legal trade and combating illegal trade in pangolin scales. However, this community has been largely overlooked by previous conservation interventions directed at the pangolin scale trade. There has also been little research into the involvement of the TCM community in pangolin scale trade in China. To fill these knowledge gaps, we interviewed TCM doctors from 41 hospitals, shop owners/assistants from 90 TCM shops, two TCM wholesalers, and 2,168 members of the general public in Henan and Hainan provinces, China. Respondents' knowledge of and attitudes towards the pangolin scale trade were investigated using semi‐structured and structured questionnaires, with a total of 2,301 respondents. Our results show that TCM practitioners generally have poor awareness of the illegal nature of their behaviours and pangolin scale products involved. Awareness is particularly poor among participants at the end of the trade chain (i.e. end sellers). The public also generally lacked understanding of pangolin products in markets. Results also show that 20 (71%) of 28 doctors believed that the use of pangolin scales in at least some, if not all, treatments could be substituted by other ingredients. These findings suggest that raising awareness of the legality of pangolin scale products and petitioning TCM communities to use alternative substitutes for these products could constitute feasible and effective pangolin conservation interventions. This study provides the first insights into the knowledge of and attitudes towards the pangolin scale trade from the perspective of TCM practitioners, and suggests that collaborating with the TCM community is necessary to combat this illegal trade.

Conservation lacks sufficient well-trained leaders who are empowered to catalyse positive change for the natural world. Addressing this need, the University of Cambridge launched a Masters in Conservation Leadership in 2010. The degree includes several features designed to enhance its impact. Firstly, it recruits international, gender-balanced cohorts of mid-career professionals, building leadership capacity in the Global South and providing a rich environment for peer learning. Secondly, teaching includes applied leadership training in topics such as fundraising, leading people and networking, as well as interdisciplinary academic topics. Thirdly, the degree is delivered through the Cambridge Conservation Initiative, a partnership of international NGOs and networks, facilitating extensive practitioner-led and experiential learning. We present details of programme design and evaluate the impact of the Masters after 10 years, using data from course records, student and alumni perspectives, and interviews with key stakeholders. The course has broadly succeeded in its design and recruitment objectives. Self-assessed leadership capabilities, career responsibilities and the overall impact of alumni increased significantly 5 years after graduation. However, specific impacts of alumni in certain areas, such as on their professional colleagues, have been less clear. We conclude by outlining future plans for the Masters in light of growing demands on conservation leaders and the changing landscape of leadership capacity development. These include reforms to course structure and assessment, long-term support to the alumni network and developing a conservation leadership community of practice.

Overexploitation is a critical threat to the survival of many species. The global demand for wildlife products has attracted considerable research attention, but regional species exploitation histories are more rarely investigated. We interviewed 169 villagers living around seven terrestrial nature reserves on Hainan Island, China, with the aim of reconstructing historical patterns of hunting and consumption of local wildlife, including the globally threatened Chinese pangolin (Manis pentadactyla) and Hainan peacock-pheasant (Polyplectron katsumatae), from the mid-20th century onwards. We aimed to better understand the relationship between these past activities and current consumption patterns. Our findings suggest that eating pangolin meat was not a traditional behaviour in Hainan, with past consumption prohibited by local myths about pangolins. In contrast, local consumption of peacock-pheasant meat was a traditional activity. However, later attitudes around hunting pangolins and peacock-pheasants in Hainan were influenced by pro-hunting policies and a state-run wildlife trade from the 1960s to the 1980s. These new social norms still shape the daily lifestyles and perceptions of local people towards wildlife consumption in Hainan today. Due to these specific historical patterns of wildlife consumption, local-adapted interventions such as promoting substitute meat choices and alternative livelihoods might be effective at tackling local habits of consuming wild meat. Our study highlights the importance of understanding the local historical contexts of wildlife use for designing appropriate conservation strategies.

Tigers are critically endangered due to deforestation and persecution. Yet in places, Sumatran tigers (Panthera tigris sumatrae) continue to coexist with people, offering insights for managing wildlife elsewhere. Here, we couple spatial models of encounter risk with information on tolerance from 2386 Sumatrans to reveal drivers of human–tiger conflict. Risk of encountering tigers was greater around populated villages that neighboured forest or rivers connecting tiger habitat; geographic profiles refined these predictions to three core areas. People’s tolerance for tigers was related to underlying attitudes, emotions, norms and spiritual beliefs. Combining this information into socio-ecological models yielded predictions of tolerance that were 32 times better than models based on social predictors alone. Pre-emptive intervention based on these socio-ecological predictions could have averted up to 51% of attacks on livestock and people, saving 15 tigers. Our work provides further evidence of the benefits of interdisciplinary research on conservation conflicts., Human-tiger conflict occurs where there is a higher risk of encountering tigers. Here, Struebig et al. use geographic profiling to predict risk of encounters in Sumatra, and show that combining risk measures with social data on tolerance could help prioritise regions for conflict mitigation efforts.

The snow leopard Panthera uncia is a vulnerable wild felid native to mountainous regions of 12 Asian countries. It faces numerous overlapping threats, including killings by herders retaliating against livestock losses, the illegal wildlife trade, loss of prey and habitat, infrastructure, energy and mining developments, and climate change. The species ranges over large territories that often lie outside of protected areas (PA), so coexistence with human populations across its range is key to its persistence. Human attitudes to snow leopards may be an important factor to consider in reducing overlapping threats to this species. However, this nexus has not been widely studied to date. Attitudes to snow leopard conservation, including actors and interventions, may also be a significant aspect of coexistence. These have also received limited empirical attention. This study therefore explored human attitudes to snow leopards and to snow leopard conservation, the motivations for these attitudes and the individual factors that best explained them. Using systematic sampling, a quantitative questionnaire was administered to 705 households at two sites in the Nepal Himalayas: Sagarmatha National Park, with a less decentralised governance model, and Annapurna Conservation Area, with a more decentralised model. Linear regression models were the main form of analysis. Based on these, attitudes to snow leopard conservation emerged as the strongest influence on local attitudes to snow leopards, and vice versa. This was true in both PAs, despite their differing management regimes. Other important explanatory factors included numbers of livestock owned, years of education, household livelihoods and age. Furthermore, a positive intrinsic motivation was the most common reason given by respondents to explain their attitudes to both snow leopards and snow leopard conservation. These findings demonstrate that, in addition to the usual suite of factors that influence attitudes to a species, the way in which its conservation is pursued and perceived also needs consideration. How the snow leopard is conserved may strongly influence its coexistence with local communities.

Human-wildlife conflict is increasing due to rapid natural vegetation loss and fragmentation. We investigated seasonal, temporal and spatial trends of elephant crop-raiding in the Trans Mara, Kenya during 2014–2015 and compared our results with a previous study from 1999 to 2000. Our results show extensive changes in crop-raiding patterns. There was a 49% increase in incidents between 1999 -2000 and 2014–2015 but an 83% decline in the amount of damage per farm. Crop-raiding went from highly seasonal during 1999–2000 to year-round during 2014–2015, with crops being damaged at all growth stages. Additionally, we identified a new elephant group type involved in crop-raiding, comprising of mixed groups. Spatial patterns of crop-raiding also changed, with more incidents during 2014–2015 neighbouring the protected area, especially by bull groups. Crop-raiding intensity during 2014–15 increased with farmland area until a threshold of 0.4 km2 within a 1 km2 grid square, and farms within 1 km from the forest boundary, 2 km from village centres were most at risk of crop-raiding. In the last 20 years the Mara Ecosystem has been impacted by climate change, agricultural expansion and increased cattle grazing within protected areas. Elephants seem to have responded by crop-raiding closer to refuges, more frequently and throughout the year but cause less damage overall. While this means the direct economic impact has dropped, more farmers must spend more time protecting their fields, further reducing support for conservation in communities who currently receive few benefits from living with wildlife.

Summary The United Nations recently listed illegal wildlife trade as a serious crime because of the escalating demand for highly prized species, such as tiger and rhinoceros, and the failure to effectively control the trade. In turn, this places greater urgency on reducing supply by securing source populations of these species. Yet, whether law enforcement strategies designed to mitigate poaching are succeeding remains poorly understood, despite the millions of dollars invested annually in this mainstay conservation strategy. Here, we assess the performance of one of Asia's longest running law enforcement programmes, from Kerinci Seblat National Park in Sumatra, by investigating whether forest ranger patrols reduced the occurrence of snare traps set for tiger and its ungulate prey base; local informant reports on poaching influenced ranger patrol success; and the resulting population trends of target species changed in response to these conservation actions. A total of 4433 snare traps were removed during 642 foot patrols conducted from 2000 to 2010. Controlling for the influence of varying detection probabilities, as well as accessibility and other possible determinants of illegal hunting, revealed that sites with a greater frequency of patrols, rather than the combined distance walked, had a lower occurrence of snare traps in succeeding years. Patrols conducted on the basis of local informant ‘tip-offs’ were significantly more likely to detect snare traps than routine patrols, with reports increasing detections by over 40%. There were no significant changes in the occupancy status of the tiger prey base from 2004 to 2011, suggesting that it remained stable during this period. The relatively good condition of prey and predator populations in Kerinci Seblat National Park was further supported by the results of an independent survey conducted in 2008–2009 which revealed a widespread tiger occurrence. Synthesis and applications. Our results not only demonstrate the effectiveness of the Kerinci Seblat law enforcement strategy in protecting wildlife, but highlight the benefits from cultivating a network of reliable informants. The study also represents a critical step in helping these urgently needed conservation assessments to become common place in the fight to save flagship species.

Human-wildlife conflict negatively affects farmers’ livelihoods and wildlife species that may already be threatened. In Sumatra, the sun bear Helarctos malayanus is a little-known and potentially significant conflict species. To understand the characteristics of human-sun bear conflict and local perceptions and tolerance towards the species, semi-structured interviews were conducted among 120 farmers from four study areas in west-central Sumatra. Spatio-temporal conflict patterns were then investigated in 30 farms from one selected study area. Overall, 45.8 % of respondents reported having experienced human-sun bear conflicts since occupying their farm and crop raiding characterised the majority of these conflicts. Farmers who experienced property damage and livestock depredation by sun bears were less tolerant towards the species and favoured conflict management strategies that removed sun bears from their area. Conflict events were positively correlated with rainfall and peaked when important cash crops reached maturity. With the current rate of agricultural expansion in west-central Sumatra human-sun bear conflicts are likely to increase. This study suggests that mitigation strategies should be implemented as crops mature for harvest, where such measures would no doubt lessen raids by other conflict species.

Between 1990 and 2007, 15 southern white (Ceratotherium simum simum) and black (Diceros bicornis) rhinoceroses on average were killed illegally every year in South Africa. Since 2007 illegal killing of southern white rhinoceros for their horn has escalated to >950 individuals/year in 2013. We conducted an ecological–economic analysis to determine whether a legal trade in southern white rhinoceros horn could facilitate rhinoceros protection. Generalized linear models were used to examine the socioeconomic drivers of poaching, based on data collected from 1990 to 2013, and to project the total number of rhinoceroses likely to be illegally killed from 2014 to 2023. Rhinoceros population dynamics were then modeled under 8 different policy scenarios that could be implemented to control poaching. We also estimated the economic costs and benefits of each scenario under enhanced enforcement only and a legal trade in rhinoceros horn and used a decision support framework to rank the scenarios with the objective of maintaining the rhinoceros population above its current size while generating profit for local stakeholders. The southern white rhinoceros population was predicted to go extinct in the wild

Trophy hunting can provide economic incentives to conserve wild species, but it can also involve risk when rare species are hunted. The anthropogenic Allee effect (AAE) is a conceptual model that seeks to explain how rarity may spread the seeds of further endangerment. The AAE model has increasingly been invoked in the context of trophy hunting, increasing concerns that such hunting may undermine rather than enhance conservation efforts. We question the appropriateness of uncritically applying the AAE model to trophy hunting for 4 reasons. First, the AAE assumes an open-access resource, which is a poor characterization of most trophy-hunting programs and obscures the potential for state, communal, or private-property use rights to generate positive incentives for conservation. Second, study results that show the price of hunting increases as the rarity of the animal increases are insufficient to indicate the presence of AAE. Third, AAE ignores the existence of biological and behavioral factors operating in most trophy-hunting contexts that tend to regulate the effect of hunting. We argue that site-specific data, rather than aggregated hunting statistics, are required to demonstrate that patterns of unsustainable exploitation can be well explained by an AAE model. Instead, we suggest that conservation managers seeking to investigate and identify constraints that limit the potential conservation role of trophy hunting, should focus on the critical governance characteristics that shape the potential conservation role of trophy hunting, such as corruption, insecure property rights, and inadequate sharing of benefits with local people.

The Guassa area of Menz in the Central Highlands of Ethiopia is an Afro-alpine ecological community with an indigenous resource management system. The local community harvest different resources including collecting grass and firewood from the Guassa area. Cattle and other livestock are also grazed in the Guassa area, especially during the dry season. Several sympatric species of endemic rodents dominate the small mammal ecological communities in the Guassa area, and form most of the diet of the endangered Ethiopian wolf. This study aimed to determine if current levels of resource use by the local community through the indigenous resource management system had any discernible effect on rodent community structure. We found that the structure of the rodent community differs between habitat types, and that different species of rodents show diurnal variations in their patterns of activity. We also found that populations of different species show variable responses to each type of resource use in different habitats; some species show increases in abundance in relation to use while others show decreases. Although the indigenous resource management system was not specifically designed to conserve wildlife, it has nevertheless allowed wildlife, specifically small mammals or rodent communities, to co-exist alongside the ongoing resource use by the local community. We conclude the Guassa area represents an interesting model of community-led resource management of an Afro-alpine habitat which supports populations of endemic and threatened species. © 2012 Ashenafi et al.

In our paper [1xBanning trophy hunting will exacerbate biodiversity loss. Di Minin, E. et al. Trends Ecol. Evol. 2016; 31: 99–102Abstract | Full Text | Full Text PDF | PubMed | Scopus (1)See all References[1] we discussed the importance of trophy hunting as a conservation tool provided it can be done in a controlled manner to benefit biodiversity conservation and local people. To address some of the concerns about trophy hunting, we proposed adopting 12 new recommendations that embrace the guiding principles on trophy hunting promoted by the International Union for the Conservation of Nature. Ripple et al.’s comment [2xDoes trophy hunting support biodiversity?. Ripple, W. et al. Trends Ecol. Evol. 2016; 31: 495–496See all References[2] on our paper argues that greater consideration needs to be given to the ecological and evolutionary effects of trophy hunting to evaluate it fully as a conservation tool. Most of the concerns that they raise have already been raised and are not restricted to trophy hunting. In fact, these same concerns also apply to conservation areas where ecotourism is the primary land use. In addition, their reply is limited in scope because their concerns apply mainly to a single country – South Africa – and have been discussed in detail elsewhere [3xAn Assessment of the Economic, Social and Conservation Value of the Wildlife Ranching Industry and its Potential to Support the Green Economy in South Africa. Taylor, A. et al. See all References[3].In this reply, we restate the importance of trophy hunting to create incentives for biodiversity conservation, preventing habitat loss, and highlight how improvements in conservation policy can be used to address some of the concerns raised. Ripple et al. [2xDoes trophy hunting support biodiversity?. Ripple, W. et al. Trends Ecol. Evol. 2016; 31: 495–496See all References[2] state that ecotourists account for ‘… an extremely small fraction of total global greenhouse gas emissions, and these emissions cannot be linked to biodiversity at trophy hunting sites’. However, not only did they neglect to quantify this fraction but they also overlooked the problem that the contribution of emissions from tourism to climate change sets a potentially major challenge for the sustainability of international tourism. Indeed, tourism transport, accommodation, and associated activities contributed an estimated 5% of global anthropogenic CO2 emissions in 2005 [4xClimate Change and Tourism. Responding to Global Challenges. Scott, D. et al. See all References[4]. Climate change is already threatening the persistence of biodiversity at trophy-hunting sites, as demonstrated by the increasing frequency of extreme El Nino events (e.g., the current drought threatening southern Africa) [5xIncreasing frequency of extreme El Nino events due to greenhouse warming. Cai, W. et al. Nat. Clim. Chang. 2014; 4: 111–116Crossref | Scopus (133)See all References[5]. Ripple et al. [2xDoes trophy hunting support biodiversity?. Ripple, W. et al. Trends Ecol. Evol. 2016; 31: 495–496See all References[2] also mentioned how maintaining large populations of targeted species, especially large herbivores, can affect biodiversity via overgrazing/browsing, but this issue is not restricted to areas where trophy hunting is the main land use; rather, it is common to most small, fenced conservation areas where ecotourism is the dominant activity [6xShort term effects of single species browsing release by different sized herbivores on Sand Forest vegetation community. Lagendijk, G. et al. South Afr. Biotropica. 2012; 44: 63–72Crossref | Scopus (8)See all References[6].Despite already raising the issue in our paper and providing recommendations to avoid such consequences [1xBanning trophy hunting will exacerbate biodiversity loss. Di Minin, E. et al. Trends Ecol. Evol. 2016; 31: 99–102Abstract | Full Text | Full Text PDF | PubMed | Scopus (1)See all References[1], Ripple et al. [2xDoes trophy hunting support biodiversity?. Ripple, W. et al. Trends Ecol. Evol. 2016; 31: 495–496See all References[2] stated how trophy hunting can disrupt community structure and functioning, with evolutionary-scale consequences when ‘… less [economically] valuable species are replaced by more [economically] valuable species, or where predators are persecuted to protect [economically] valuable large herbivores’. However, this concern is mainly limited to South Africa where many wildlife populations are artificially managed within fenced reserves. The full range of species needed to create a functional ecosystem might not be available at trophy hunting sites (this is also the case of conservation areas where ecotourism is the main land use and where many species have been historically extirpated). The main weakness of this critique is that unless harvest is intensive and affects a large proportion of the adult population (i.e., decidedly not the case for most trophy-hunted species in Africa), negative evolutionary consequences of harvest are unlikely. Our recommendation for population viability analyses [1xBanning trophy hunting will exacerbate biodiversity loss. Di Minin, E. et al. Trends Ecol. Evol. 2016; 31: 99–102Abstract | Full Text | Full Text PDF | PubMed | Scopus (1)See all References[1] that include the evolutionary consequences of harvest are certainly advisable in cases where rare or small-population species are trophy-hunted. Additionally, species richness and community structure are higher in these intensively managed sites compared with agricultural and other competing land uses [7xAgricultural expansion and its impacts on tropical nature. Laurance, W.F. et al. Trends Ecol. Evol. 2014; 29: 107–116Abstract | Full Text | Full Text PDF | PubMed | Scopus (110)See all References[7]. Predator persecution is indeed an issue in South Africa, although national and local conservation authorities are responding to this problem by implementing evidence-based conservation actions (e.g., [8xImpact of conservation interventions on the dynamics and persistence of a persecuted leopard (Panthera pardus) population. Balme, G.A. et al. Biol. Conserv. 2009; 142: 2681–2690Crossref | Scopus (43)See all References[8]). Additionally, a year-long ban on leopard hunting has been imposed in 2016 to gather more evidence on the size of South Africa's leopard population [9xSee all References[9].Even though the problem applies equally to ecotourism, the issue with managed species derived from elsewhere in South Africa can be addressed by improving current policies (e.g., the Biodiversity Act in South Africa) to prevent introductions of such ex situ species. However, there is considerable debate globally regarding what constitutes a species’ ‘previous’ range, and whether this should be the dominant consideration when deciding whether to assist migration in light of shifting climates [10xAssisted migration: part of an integrated conservation strategy. Vitt, P. et al. Trends Ecol. Evol. 2009; 24: 473–474Abstract | Full Text | Full Text PDF | PubMed | Scopus (40)See all References[10]. Furthermore, the South African Hunters and Game Conservation Association have strongly denounced selective and intensive game breeding practices (e.g., enhancing or altering genetic characteristics of game species for commercial purposes, including artificial and unnatural manipulation to achieve unusual coat colors and excessive horn lengths), and they have called upon the South African government to implement conservation strategies in the interest of protecting the country's biodiversity [11xHunting Body Calls for Regulation of Intensive Commercial Game Breeding Practices. South African Hunters and Game Conservation Association. See all References[11].In conclusion, we reiterate how the lack of incentives generated from trophy hunting will worsen biodiversity loss, but that compared with ecotourism, trophy hunting can provide much greater area-based returns to funding conservation and have fewer negative impacts in terms of emissions and ecosystem functioning. Our recommendations [1xBanning trophy hunting will exacerbate biodiversity loss. Di Minin, E. et al. Trends Ecol. Evol. 2016; 31: 99–102Abstract | Full Text | Full Text PDF | PubMed | Scopus (1)See all References[1] require that resources generated from trophy hunting are used to monitor targeted (and even non-targeted) species and ecosystems. Without doubt, there is a need to improve and enforce national policies that consider the ecological, social, and economic issues around trophy hunting. Furthermore, we support the notion that the conservation community would benefit from a better understanding of the ethics of trophy hunting [12xEmotions and the ethics of consequence in conservation decisions: lessons from Cecil the Lion. Nelson, M.P. et al. Conserv. Lett. 2016; CrossrefSee all References[12].

Mammalian carnivores have suffered the biggest range contraction among all biodiversity and are particularly vulnerable to habitat loss and fragmentation. Therefore, we identified priority areas for the conservation of mammalian carnivores, while accounting for species-specific requirements for connectivity and expected agricultural and urban expansion. While prioritizing for carnivores only, we were also able to test their effectiveness as surrogates for 23,110 species of amphibians, birds, mammals and reptiles and 867 terrestrial ecoregions. We then assessed the risks to carnivore conservation within each country that makes a contribution to global carnivore conservation. We found that land use change will potentially lead to important range losses, particularly amongst already threatened carnivore species. In addition, the 17% of land targeted for protection under the Aichi Target 11 was found to be inadequate to conserve carnivores under expected land use change. Our results also highlight that land use change will decrease the effectiveness of carnivores to protect other threatened species, especially threatened amphibians. In addition, the risk of human-carnivore conflict is potentially high in countries where we identified spatial priorities for their conservation. As meeting the global biodiversity target will be inadequate for carnivore protection, innovative interventions are needed to conserve carnivores outside protected areas to compliment any proposed expansion of the protected area network.

It is argued that trophy hunting of large, charismatic mammal species can have considerable conservation benefits but only if undertaken sustainably. Social-ecological theory suggests such sustainability only results from developing governance systems that balance financial and biological requirements. Here we use lion (Panthera leo) trophy hunting data from Tanzania to investigate how resource ownership patterns influence hunting revenue and offtake levels. Tanzania contains up to half of the global population of free-ranging lions and is also the main location for lion trophy hunting in Africa. However, there are concerns that current hunting levels are unsustainable. The lion hunting industry in Tanzania is run by the private sector, although the government leases each hunting block to companies, enforces hunting regulation, and allocates them a species-specific annual quota per block. The length of these leases varies and theories surrounding property rights and tenure suggest hunting levels would be less sustainable in blocks experiencing a high turnover of short-term leases. We explored this issue using lion data collected from 1996 to 2008 in the Selous Game Reserve (SGR), the most important trophy hunting destination in Tanzania. We found that blocks in SGR with the highest lion hunting offtake were also those that experienced the steepest declines in trophy offtake. In addition, we found this high hunting offtake and the resultant offtake decline tended to be in blocks under short-term tenure. In contrast, lion hunting levels in blocks under long-term tenure matched more closely the recommended sustainable offtake of 0.92 lions per 1000 km2. However, annual financial returns were higher from blocks under short-term tenure, providing $133 per km2 of government revenue as compared to $62 per km2 from long-term tenure blocks. Our results provide evidence for the importance of property rights in conservation, and support calls for an overhaul of the system in Tanzania by developing competitive market-based approaches for block allocation based on long-term tenure of ten years.

Several studies suggest that protected areas conserve forests because deforestation rates are lower inside than outside protected area boundaries. Such benefits may be overestimated when deforestation rates within protected areas are contrasted with rates in lands where forest conversion is sanctioned. Here, we reexamine protected area performance by disentangling the effects of land use regulations surrounding the 110,000 km 2 protected area network in Sumatra, Indonesia.

Conflicts between protected-area managers and local people are common, but the drivers of conflict are rarely analyzed. This limits opportunities to identify strategies that reduce conflict and the magnitude of resulting threats to conservation. Integrated conservation and development (ICD) was adopted at Bwindi Impenetrable Forest, Uganda, to reduce conflict during gazettement of the national park, but the success of this approach remains contested. We retrieved documents of conflict written by park staff and local people from 1986 through 2000 (before, during, and after gazettement). We extracted data on 48 incidences of violent conflict and categorized them by gazettement period, area, instigator, and type to undertake a historical analysis of the triggers of violent conflict at Bwindi. Before and during gazettement, local villagers instigated most of the conflict incidents when law-enforcement efforts sought to halt commercial activities within Bwindi. No conflict arose from the arrest of villagers collecting subsistence resources during these periods. After gazettement, prohibitions on commercial activities continued to drive conflict even though villagers collecting subsistence resources were arrested more frequently than before gazettement, and local attitudes toward the park had improved following receipt of ICD benefits. Law-enforcement efforts targeted commercial activities to reduce this threat to Bwindi's mountain gorillas (Gorilla beringei beringei), although the activities remained important income sources for people in villages near Bwindi. Losing commercial income following gazettement therefore appeared to be their primary motivation for instigating conflict with park rangers. Prohibitions on subsistence resource use triggered conflict less often. Our use of typologies for a multivariate conflict analysis demonstrates that by identifying differences between effects of conservation as drivers of conflict, conflict analysis can enable a more strategic deployment of conflict-resolution measures that could further conservation efforts. At Bwindi targeting ICD toward individuals who lost benefits from commercial activities may strengthen the role of ICD in conflict resolution and conservation.

Curtailing overharvest, whether illegal or legal, is often a critical conservation objective. Yet even if overexploitation can be stopped, subsequent rates of population recovery can be highly variable due to Allee effects, alterations to age and sex structure and disruptions of animal social systems. Moreover, understanding the influence of density dependence can be difficult but important for long-term management. Here, we investigate the dynamics of black rhinoceros Diceros bicornis in the Kunene region of Namibia as they recover from illegal hunting. We use multi-strata mark–recapture models to examine survival and stage-transition rates from 1992 to 2005. Survivorship estimates ranged from 0.793 for calves to 0.910 for adult males and 0.944 for adult females. The annual reproductive rate in adult females was estimated at 0.315. Model selection showed that these vital rates were time invariant, suggesting that Allee effects and transient dynamics did not have an important effect upon population dynamics, even in the early stages of recovery. Relative population density increased significantly from 1992 to 2005 once illegal hunting had ceased in Kunene. However, the best-fit models did not include relative density in the estimation of survival or stagetransition rates. We then used the vital rates generated from our mark–recapture analysis to build matrix projection models that assessed overall population dynamics. The female-only model gave a population growth rate estimate of l = 1.011. Two-sex models suggest that the growth rate of the population could range from 0.990 to 1.012. The relatively slow growth rate of this population, even without hunting or density dependence, could stem from the low productivity of the region. Adult females had the highest reproductive value and their survival had the highest elasticity among vital rates. Translocating adult females would lead to the fastest initial population growth rate in founder populations but would have the most impact on the source population.

Religious beliefs and spiritual connections to biodiversity have the potential to reduce animosity towards wildlife that might otherwise present a real or perceived threat to local people. Understanding this social dynamic can therefore be important for formulating locally-appropriate species-specific conservation strategies. Using semi-structured interviews which incorporated human-tiger conflict scenarios, we investigated how beliefs towards tigers varied between ethnic groups living around a large protected area that is home to the largest tiger population in Sumatra. We gathered this information to determine the degree to which cultural tolerance may contribute to the survival of the tiger in the Kerinci Seblat landscape, Indonesia. From 154 interviewees, 133 respondents came from three main ethnic groups, Minangkabau, Kerincinese and Melayu. The majority (73.5%) of Minangkabau interviewees cited that their ethnic group had customary laws regarding tigers, as did 52% of Melayu and 44% of Kerincinese. Irrespective of ethnicity, most participants did not perceive there to be a connection between Islam and tigers. All participants acknowledged the existence of zoological tigers and two groups (Minangkabau and Kerincinese) held a strong common belief that different types of spirit tigers also existed. From presenting different human-tiger conflict scenarios, with varying levels of severity towards livestock or human life, an unprovoked tiger attack in the village elicited the most calls for the tiger to be killed. Yet, if a village or family member was killed by a tiger whilst hunting in the forest then most respondents across all ethnic groups said to do nothing. The frequency of this response increased if a tiger killed someone in the village who had committed adultery, reflecting beliefs associated with the role of the tiger as an enforcer of moral rule. Our study highlights the importance of consulting with local communities who live in close proximity to large and potentially dangerous carnivores when developing conflict mitigation strategies, which hitherto has not been the case in Sumatra.

Human–wildlife conflicts, such as crop-raiding, increase as people expand their agricultural activities into wildlife habitats. Crop-raiding can reduce tolerance toward species that are already threatened, whereas potential dangers posed by conflicts with large-bodied species may also negatively influence local attitudes. Across Asia, wild pigs and primates, such as macaques, tend to be the most commonly reported crop raiders. To date, reports of crop-raiding incidents involving great apes have been less common, but incidents involving orangutans are increasingly emerging in Indonesia. To investigate the interplay of factors that might explain attitudes toward crop-raiding by orangutans (Pongo abelii), focal group discussions and semi-structured interviews were conducted among 822 farmers from 2 contrasting study areas in North Sumatra. The first study area of Batang Serangan is an agroforest system containing isolated orangutans that crop-raid. In contrast, the second area of Sidikalang comprises farmlands bordering extensive primary forest where orangutans are present but not reported to crop-raid. Farmers living in Batang Serangan thought that orangutans were dangerous, irrespective of earlier experience of crop-raiding. Farmers placed orangutans as the third most frequent and fourth most destructive crop pest, after Thomas' leaf monkey (Presbytis thomasi), wild boar (Sus scrofa), and long-tailed macaque (Macaca fascicularis). Although most (57%) farmers across both study areas were not scared of wildlife species, more than a quarter (28%) of the farmers' feared orangutans. Farmers in Batang Serangan were generally more tolerant toward crop-raiding orangutans, if they did not perceive them to present a physical threat. Most (67%) Batang Serangan farmers said that the local Forestry Department staff should handle crop-raiding orangutans, and most (81%) said that these officials did not care about such problems. Our results suggest that efforts to mitigate human–orangutan conflict may not, per se, change negative perceptions of those who live with the species, because these perceptions are often driven by fear.

Tolerance may lessen when wildlife adversely impacts people. Models from psychology can help elucidate how people make judgments, why they act accordingly, and whether beliefs and norms influence support for policy and intervention. Working in a globally important region for tigers, we estimated hunting prevalence for this endangered species and three sympatric taxa using methods for asking sensitive questions. We also investigated the relative strength of ethnicity and social‐psychological predictors in influencing intention to hunt. Men's behavioral intention and perceptions differed by species: proconservation values were most prevalent for tiger, weakest for wild boar. Perceived behavioral control was the strongest predictor of hunting‐intention; affect and injunctive norms were also important. The prominence of affect in determining intention suggests increasing environmental knowledge is unlikely to curb hunting. However, existing norms could be leveraged to incentivize behaviorchange. Integrating behavior‐change models into conservation science is crucial where strategies require changes in people's actions.

Across Africa, national policies that established protected areas (PAs) typically limited local use of wildlife and other resources. Over time, these policies have raised tensions with rural communities and today threaten to undermine conservation goals. This article examines community–PA relationships at four important sites in Ethiopia—a country of rich tradition with an unusual colonial past. Using focus groups and household surveys, we found that despite local tensions, most respondents held positive views toward wildlife and nearby PAs. Factors influencing positive views included receiving PA benefits, good relations with PA staff, higher education levels, being older, having a large family, diversified income sources, owning fewer livestock, and fewer incidents of wildlife conflicts. In contrast, the devolved control of PAs from federal to regional levels has not influenced community–PA relations as intended. Our results suggest that relations could be improved through involving communities in co-ma...

Aim This study determines whether the establishment of tropical protected areas (PAs) has led to a reduction in deforestation within their boundaries or whether deforestation has been displaced to adjacent unprotected areas: a process termed neighbourhood leakage. Location Sumatra, Indonesia. Methods We processed and analysed 98 corresponding LANDSAT satellite images with a c. 800 m2 resolution to map deforestation from 1990 to 2000 across 440,000 km2 on the main island of Sumatra and the smaller island of Siberut. We compared deforestation rates across three categories of land: (1) within PAs; (2) in adjacent unprotected land lying with 10 km of PA boundaries; and (3) within the wider unprotected landscape. We used the statistical method of propensity score matching to predict the deforestation that would have been observed had there been no PAs and to control for the generally remote locations in which Sumatran PAs were established. Results During the period 1990–2000 deforestation rates were found to be lower inside PAs than in adjacent unprotected areas or in the wider landscape. Deforestation rates were also found to be lower in adjacent unprotected areas than in the wider landscape. Main conclusions Sumatran PAs have lower deforestation rates than unprotected areas. Furthermore, a reduction in deforestation rates inside Sumatran PAs has promoted protection, rather than deforestation, in adjacent unprotected land lying within 10 km of PA boundaries. Despite this positive evaluation, deforestation and logging have not halted within the boundaries of Sumatran PAs. Therefore the long-term viability of Sumatran forests remains open to question.

The International Union for Conservation of Nature (IUCN) Red List of Threatened Species was increasingly used during the 1980s to assess the conservation status of species for policy and planning purposes. This use stimulated the development of a new set of quantitative criteria for listing species in the categories of threat: critically endangered, endangered, and vulnerable. These criteria, which were intended to be applicable to all species except microorganisms, were part of a broader system for classifying threatened species and were fully implemented by IUCN in 2000. The system and the criteria have been widely used by conservation practitioners and scientists and now underpin one indicator being used to assess the Convention on Biological Diversity 2010 biodiversity target. We describe the process and the technical background to the IUCN Red List system. The criteria refer to fundamental biological processes underlying population decline and extinction. But given major differences between species, the threatening processes affecting them, and the paucity of knowledge relating to most species, the IUCN system had to be both broad and flexible to be applicable to the majority of described species. The system was designed to measure the symptoms of extinction risk, and uses 5 independent criteria relating to aspects of population loss and decline of range size. A species is assigned to a threat category if it meets the quantitative threshold for at least one criterion. The criteria and the accompanying rules and guidelines used by IUCN are intended to increase the consistency, transparency, and validity of its categorization system, but it necessitates some compromises that affect the applicability of the system and the species lists that result. In particular, choices were made over the assessment of uncertainty, poorly known species, depleted species, population decline, restricted ranges, and rarity; all of these affect the way red lists should be viewed and used. Processes related to priority setting and the development of national red lists need to take account of some assumptions in the formulation of the criteria.La Lista Roja de Especies Amenazadas de la UICN (Union Internacional para la Conservacion de la Naturaleza) fue muy utilizada durante la decada de l980 para evaluar el estatus de conservacion de especies para fines politicos y de planificacion. Este uso estimulo el desarrollo de un conjunto nuevo de criterios cuantitativos para enlistar especies en las categorias de amenaza: en peligro critico, en peligro y vulnerable. Estos criterios, que se pretendia fueran aplicables a todas las especies excepto microorganismos, eran parte de un sistema general para clasificar especies amenazadas y fueron implementadas completamente por la UICN en 2000. El sistema y los criterios han sido ampliamente utilizados por practicantes y cientificos de la conservacion y actualmente apuntalan un indicador utilizado para evaluar el objetivo al 2010 de la Convencion de Diversidad Biologica. Describimos el proceso y el respaldo tecnico del sistema de la Lista Roja de la IUCN. Los criterios se refieren a los procesos biologicos fundamentales que subyacen en la declinacion y extincion de una poblacion. Pero, debido a diferencias mayores entre especies, los procesos de amenaza que los afectan y la escasez de conocimiento sobre la mayoria de las especies, el sistema de la UICN tenia que ser amplio y flexible para ser aplicable a la mayoria de las especies descritas. El sistema fue disenado para medir los sintomas del riesgo de extincion, y utiiza cinco criterios independientes que relacionan aspectos de la perdida poblacional y la declinacion del rango de distribucion. Una especie es asignada a una categoria de amenaza si cumple el umbral cuantitativo por lo menos para un criterio. Los criterios, las reglas acompanantes y las directrices utilizadas por la UICN tienen la intencion de incrementar la consistencia, transparencia y validez de su sistema de clasificacion, pero requiere algunos compromisos que afectan la aplicabilidad del sistema y las listas de especies que resultan. En particular, se hicieron selecciones por encima de la evaluacion de incertidumbre, especies poco conocidas, especies disminuidas, declinacion poblacional, rangos restringidos y rareza; todas estas afectan la forma en que las listas rojas deberian ser vistas y usadas. Los procesos relacionados con la definicion de prioridades y el desarrollo de las listas rojas nacionales necesitan considerar algunos de los supuestos en la formulacion de los criterios.

Wild bird conservation in the UK is a widely regarded as a success story. The populations of many endangered species have grown or at least stabilised, birds that were last seen in the UK over 100 years ago have been successfully re-introduced, and bird watching makes an increasingly important contribution to the rural economy in terms of employment and income. Nevertheless, some wild birds also generate costs and some deep rooted conflicts persist with other rural activities such as farming and game shooting. This paper describes a conceptual framework for understanding the costs and benefits of wild birds and, using wild goose conservation in the island of Islay as a case study, explores whether continued public investment in wild goose conservation is worthwhile from an economic perspective. The paper concludes with a discussion about future options for integrating wild bird conservation with sustainable rural development.

Many of the large, donor-funded community-based conservation projects that seek to reduce biodiversity loss in the tropics have been unsuccessful. There is, therefore, a need for empirical evaluations to identify the driving factors and to provide evidence that supports the development of context-specific conservation projects. We used a quantitative approach to measure, post hoc, the effectiveness of a US$19 million Integrated Conservation and Development Project (ICDP) that sought to reduce biodiversity loss through the development of villages bordering Kerinci Seblat National Park, a UNESCO World Heritage Site in Indonesia, We focused on the success of the ICDP component that disbursed a total of US$1.5 million through development grants to 66 villages in return for their commitment to stop illegally clearing the forest. To investigate whether the ICDP lowered deforestation rates in focal villages, we selected a subset of non-ICDP villages that bad similar physical and socioeconomic features and compared their respective deforestation rates. Village participation in the ICDP and its development schemes had no effect on deforestation. Instead, accessible areas where village land-tenure had been undermined by the designation of selective-logging concessions tended to have the highest deforestation rates. Our results indicate that the goal of the ICDP was not met and, furthermore, suggest that both law enforcement inside the park and local property rights outside the park need to be strengthened. Our results also emphasize the importance of quantitative approaches in helping to inform successful and cost-effective strategies for tropical biodiversity conservation.

Crop raiding can reduce farmers' tolerance towards wildlife. Despite higher human population densities in rural areas, and more rapid conversion of forest to farmland, much less is known about crop raiding in Asia than in Africa. Over 14 months, we identified perceived and actual crop pests, and their patterns of crop raiding from farmland in and around Kerinci Seblat National Park, Sumatra. Farmers named either the wild boar Sus scrofa (80%) or the pig-tailed macaque Macaca nemestrina (20%) as the two most destructive crop pests. From 5125 crop raids by 11 species of mammal, most raids were indeed made by the wild boar (56%) and the pig-tailed macaque (19%). For all species combined, temporal crop raiding peaks were positively correlated with periods of high rainfall. Spatially, most crop raids occurred nearest to the forest edge and the local guarding strategies used were ineffective. However, raids by wild boars were more extensive than raids by pig-tailed macaques, which caused much greater crop damage (73%) than wild boars (26%), contrary to farmers' perceptions. Our research suggests that alternative mitigation strategies need to be trialed over dry and rainy seasons to identify the most effective strategies and that guarding effort should be increased during the rainy seasons and tailored towards specific crop raiding species based on their unique spatial patterns.

International pressure to ban trophy hunting is increasing. However, we argue that trophy hunting can be an important conservation tool, provided it can be done in a controlled manner to benefit biodiversity conservation and local people. Where political and governance structures are adequate, trophy hunting can help address the ongoing loss of species.

1. Crop raiding by African elephants Loxodonta africana erodes local tolerance for elephants and thereby impedes conservation efforts, so solutions are urgently required. Within conflict zones, crop raiding is not distributed equally amongst farms, which may be a result of variation in local physical or geographical factors, or in farmers' efforts to defend their fields. Understanding the efficacy of local conflict mitigation methods is important, but few quantitative evaluations exist. 2. Using a comparative survey of raided and non-raided farms in Transmara District, Kenya, and multivariate logistic and linear regression analyses, we explored a range of factors affecting (i) the susceptibility of farms to elephant crop raiding and (ii) the amount of crop damage once elephants had entered a field. 3. The results revealed that farms that had been habitually raided in the past were more likely to be raided during the study period, as were those that were larger and bordered by hedges or fences. Greater guarding effort increased the likelihood that elephants were detected prior to entry and decreased the likelihood of successful crop raiding, as did the use of fire and noise. 4. However, there was an interaction between physical and human factors; larger farms used more advanced barrier methods at the expense of guarding effort. Farmers' efforts did not appear to diminish the damage inflicted once elephants had entered a field. 5. A subsequent experimental test confirmed these results; the application of enhanced early warning and guarding effort on previously raided farms reduced incidents of crop raiding by 89.6% over 2 years in comparison with a control group of farms. 6. Synthesis and applications. These results suggest that early detection of elephants approaching fields, increased guarding effort, and the use of active deterrents could form the basis of an effective mitigation strategy regardless of location and the physical attributes of a farm. Validating the results of predictive models through participatory mitigation trials serves to demonstrate effective solutions to farmers themselves. Researchers and practitioners should be encouraged to replicate such field trials over broader spatial and temporal scales and to find means to encourage farmers to take up appropriate solutions.

A better understanding of common property resource management systems and institutions is important for conservation and development, as fortress-based approaches towards conservation are increasingly questioned. This paper examines how an indigenous resource management system has operated and supported the protection of an Afro-alpine area in the Central Highlands of Ethiopia. The community was mainly concerned to regulate their own use of natural resources, including collection of firewood and thatch, and grazing by livestock. The original common property resource management system operated under a previously undescribed indigenous institution known as the Qero system, which was enforced through sanctions and punishments imposed by the community. The Qero system was suspended following the Agrarian Reform in 1975, which resulted in the breakdown of the traditional land tenure and land rights systems within Ethiopia. In the Central Highlands, user rights and management responsibility shifted to include formerly marginalized groups. Nevertheless, the common property management system has shown sufficient resilience to withstand these changes and pressures, and is still functioning with defined user groups and byelaws to regulate resource use and manage the area. Nevertheless, attitudes to current and future management are polarized between former and present managers of the common property regime.

Many protected area (PA) systems have developed in response to socio-economic and aesthetic criteria and need to be modified to increase their conservation value. National gap analyses are an important step in describing and addressing this problem, so we sought to determine the representativeness of English PAs devoted to biodiversity conservation by using Natural Areas (NAs), elevation and PA boundary data. We found that National Nature Reserves (NNRs) and Sites of Special Scientific Interests (SSSIs) cover only 6.3% of England and are generally small, with respective median areas of 1.1 and 0.2 km2. The English PA system under-represents lowland areas and provides a median level of 2.5% protection for the NA types, with seventy nine per cent of NA types having less than 10% protection. Therefore, we suggest that England's PA system needs to be expanded, although this would probably entail modification of existing legislation to increase involvement by landowners. We also compare our results with previous appraisals that used species distribution record data and suggest that landscape-level analyses may give a more accurate and less positive assessment.

Protected area managers have limited resources and so need fine-scale information to decide where to focus their budgets for law enforcement and community outreach. This study used satellite imagery to map and analyse forest loss in an area that overlaps with Kerinci Seblat National Park, Sumatra, to identify areas most susceptible to illegal logging. Between 1985 and 1992, forest located at lower elevation and close to roads was most vulnerable to clearance. These factors were also significant between 1992 and 1999, along with distance to newly created logging roads. The presence of these roads probably explained why the deforestation rate increased from 1.1% per year to 3.0% per year over the two study periods. The accuracy of the 1985-1992 model was measured in the field and successfully predicted subsequent deforestation patterns, suggesting that this methodology could be used to identify where future patrolling effort and community outreach programmes should be focussed. In addition, this approach could be used more widely in conservation planning to prioritise the protection of vulnerable sites.

1. Human-elephant conflict (HEC) in Africa occurs wherever these two species coincide, and poses serious challenges to wildlife managers, local communities and elephants alike. Mitigation requires a detailed understanding of underlying patterns and processes. Although temporal patterns of HEC are relatively predictable, spatial variation has shown few universal trends, making it difficult to predict where conflict will take place. While this may be due to unpredictability in male elephant foraging behaviour (the male behaviour hypothesis) it may also be due to variations in the data resolution of earlier studies. 2. This study tested the male behaviour and data resolution hypotheses using HEC data from a 1000-km(2) unprotected elephant range adjacent to the Masai Mara National Reserve in Kenya. HEC incidents were divided into crop raiding and human deaths or injuries. Crop raiding was further subdivided into incidents involving only male elephants or family groups. A relatively fine-resolution, systematic, grid-based method was used to assign the locations of conflict incidents, and spatial relations with underlying variables were explored using correlation analysis and logistic regression. 3. Crop raiding was clustered into distinct conflict zones. Both occurrence and intensity could be predicted on the basis of the area under cultivation and, for male elephant groups, proximity to major settlements. Conversely, incidents of elephant-induced human injury and death were less predictable but were correlated with proximity to roads. 4. A grid-based geographical information system (GIS) with a 25-km(2) resolution utilizing cost-effective data sources, combined with simple statistical tools, was capable of identifying spatial predictors of HEC. At finer resolutions spatial autocorrelation compromised the analyses. 5. Synthesis and applications . These results suggest that spatial correlates of HEC can be identified, regardless of the sex of the elephants involved. Moreover, the method described here is fully transferable to other sites for comparative analysis of HEC. Using these results to map vulnerability will enable the development and deployment of appropriate conflict mitigation strategies, such as guarding, early warning systems, barriers and deterrents. The utility of such methods and their strategic deployment should be assessed alongside alternative land-use and livelihood strategies that limit cultivation within the elephant range.
