Human–tiger conflict arises when tigers Panthera tigris attack people or their livestock, and poses a significant threat to both tigers and people. To gain a greater understanding of such conflict we examined spatio-temporal patterns, correlates, causes and contexts of conflict in Chitwan National Park, Nepal, and its buffer zone, during 2007–2014. Data, mostly from compensation applications, were collected from the Park office. Fifty-four human casualties (32 fatalities, 22 injuries) and 351 incidents of livestock depredation were recorded, clustered in defined areas, with 75.9% of human casualties occurring in the buffer zone and 66.7% within 1 km of the Park boundary. A linear model indicated there was a significant increase in human casualties during 2007–2014. Livestock were killed in proportion to their relative availability, with goats suffering the highest depredation (55%). There was a positive correlation between livestock depredation and National Park frontage (the length of Village Development Committee/municipality boundary abutting the National Park), but not human population, livestock population, forest area in the buffer zone, rainfall or temperature. There was no relationship between tiger attacks on people and any of the correlates examined. Wild prey density was not correlated with conflict. Of the tigers removed because of conflict, 73.3% were male. The majority of attacks on people occurred during accidental meetings (77.8%), mostly while people were collecting fodder or fuelwood (53.7%), and almost half (48.2%) occurred in the buffer zone forests. We recommend the use of the conflict map developed here in the prioritization of preventive measures, and that strategies to reduce conflict should include zoning enforcement, improvement of livestock husbandry, participatory tiger monitoring, an insurance scheme, and community awareness.

Signatory states of the Convention on Biological Diversity must ‘protect and encourage the customary use of biological resources in accordance with traditional cultural practices that are compatible with conservation or sustainable use requirements’. Thus the management of traditional hunting of wildlife must balance the sustainability of target species with the benefits of hunting to traditional communities. Conservation policies usually define the values associated with wild meats in terms of income and nutrition, neglecting a wide range of social and cultural values that are important to traditional hunting communities. We elicited the community-defined benefits and costs associated with the traditional hunting of dugongs Dugong dugon and green turtles Chelonia mydas from communities on two islands in Torres Strait, Australia. We then used cognitive mapping and multidimensional scaling to identify separable groups of benefits (cultural services, provisioning services, and individual benefits) and demonstrate that traditional owners consider the cultural services associated with traditional hunting to be significantly more important than the provisioning services. Understanding these cultural values can inform management actions in accordance with the Convention on Biological Diversity. If communities are unable to hunt, important cultural benefits are foregone. Based on our results, we question the appropriateness of conservation actions focused on prohibiting hunting and providing monetary compensation for the loss of provisioning services only.

Globally, some species and habitats receive protection through local belief systems (e.g. indigenous religions) and informal institutions (e.g. social norms and taboos). Where such systems represent the only form of protection for threatened species or environments, they may be critical to the survival of those taxa and sites. We evaluated the effectiveness of long-standing social taboos protecting the Endangered Sclater's monkey Cercopithecus sclateri and forest groves in a community complex in Nigeria. Across its range (southern Nigeria), Sclater's monkey is effectively protected only through informal institutions. At our study site, we conducted a census of the monkey population; measured the area of sacred groves; and compared our findings with estimates from 2010 and 2005, respectively. We observed a 36% increase in the monkey population (from 249 to 339 individuals) in a core survey area. No groves that we assessed in 2005 had been fully cleared. Although we observed a decline in tree cover for several sacred forests, most groves used regularly by monkeys had changed little. The social taboos related to monkeys and sacred groves remain largely intact; however, other factors threaten the monkey population and remaining forests in this community complex, including the removal of tree patches to accommodate the construction of large residential buildings and the demand for cropland, as well as increased dumping of waste in forested sites. This study highlights the conservation importance and limitations of local cultural protection, as well as the challenges presented when such protection conflicts with community-perceived development needs.

Difficult terrain and inclement weather limit our knowledge of large predators, such as the tiger Panthera tigris, in the Himalayas. A lack of empirical data on large carnivores can lead to mismanagement of protected areas and population declines. We used non-invasive genetic and remote sensing data to inform the management of such high-altitude protected areas. We used the tiger as a focal species to investigate prey preference and habitat suitability in India's Buxa Tiger Reserve, which encompasses several eco-geographical regions in the Himalayan and subtropical zones. During 2010–2013, 909 faecal samples were collected, of which 372 were confirmed, using genetic analysis, to be of tiger origin. Fourteen prey species/groups were identified in 240 tiger faecal samples, largely dominated by goats Capra spp. (26.59%), rhesus macaques Macaca mulatta (22.22%) and cattle Bos spp. (20.63%). Considering only the wild prey species for which survey data are available, however, and frequency of occurrence of prey in faecal samples, hog deer Axis porcinus, sambar deer Rusa unicolor and spotted deer Axis axis were the most preferred prey species. Using faecal sample locations to examine the relationship between tiger presence and environmental features indicated that the niche for tigers is narrower than the available protected area: c. 62% of core protected area is suitable, of which only 17% is highly suitable for tigers. Tigers prefer dense vegetation, open forests, riverine vegetation and areas close to water sources. Faecal sample-based studies have the potential to generate data that can help us understand the ecology of elusive carnivore species inhabiting high-altitude landscapes.

Despite conservation discourses in Madagascar increasingly emphasizing the role of customary institutions for wildlife management, we know relatively little about their effectiveness. Here, we used semi-structured interviews with 54 adults in eight villages to investigate whether sacred caves and taboos offer conservation benefits for cave-dwelling bats in and around Tsimanampetsotsa National Park, south-west Madagascar. Although some caves were described as sites of spiritual significance for the local communities, most interviewees (c. 76%) did not recognize their present-day sacred status. Similarly, only 22% of the interviewees recognized taboos inhibiting bat hunting and consumption. Legal protection of bats and caves through protected areas was often more widely acknowledged than customary regulations, although up to 30% of the interviewees reported consumption of bats within their communities. Guano extraction was often tolerated in sacred caves in exchange for economic compensation. This may benefit bat conservation by creating incentives for bat protection, although extraction is often performed through destructive and exploitative practices with little benefit for local communities. In view of these results our study questions the extent to which sacred sites, taboos and protected areas offer protection for bats in Madagascar. These results support previous studies documenting the erosion of customary institutions in Madagascar, including the loss of the spiritual values underpinning sacred sites. Given that many Malagasy bats are cave-dwelling species and that most depend on the customary protection of these sites, it is important to obtain a better understanding of the complex interactions between spiritual practices, taboos and protected areas in sustaining bat diversity.

Meeting global and regional environmental targets is challenging, given the multiplicity of stakeholders and their diverse and often competing policy agendas and objectives. Relatively few studies have sought to systematically analyse the progress, or lack thereof, of institutionally complex and diffuse projects. Here we analyse one such project, which aims to protect and restore a critical landscape corridor for tigers Panthera tigris in north-western India, using a temporal–analytic framework that integrates ecological information on species population status and spatial connectivity modelling with a systematic examination of the decision-making process. We find that even with adequate ecological knowledge the tiger population is on the verge of local extinction because of weak institutional support, poor adaptive planning and ineffective leadership in a complex political arena, which has led to delays in conservation action. From the outset the conservation agencies and NGOs that were the primary drivers of the project lacked awareness of the political idiosyncrasies of coordinating the actions of disparate agencies within the decision-making process. To secure better future environmental outcomes we recommend the adoption of an improved project appraisal methodology that explicitly encompasses an evaluation of organizational incentives, to determine political buy-in, including alignment with organizational objectives and funding availability.

Madagascar is one of the most threatened biodiversity hotspots, and protection of its biodiversity is becoming increasingly urgent as deforestation of the island continues. For the long-term success of conservation efforts it is essential that key ecological processes, such as seed dispersal, are protected and restored. Therefore, the identification of ecological gaps is a vital task. For Madagascar, only little is known about plant–animal interactions, and traditional methods of ecological research are too time-consuming to provide crucial information about breakdowns in these interactions. To identify likely dispersal gaps we therefore used a theoretical approach to analyse plant–disperser interactions in Madagascar. We used data science tools to impute missing data on relevant plant traits to subsequently predict the most likely dispersal agents for each of Madagascar's endemic plant species. We found that 38% of the endemic species (N = 8,784) are endozoochorous, and among these 26–41% display a primate syndrome and 17–19% a bird syndrome (depending on the definition of syndromes). This lower percentage of endozoochorous species and higher percentage of species with a primate syndrome in Madagascar compared to other tropical areas reflects the unusual disperser guild on the island. Only five bird species but 20 lemur species are frugivorous, and 16 of those lemur species are currently threatened with extinction. The disappearance of frugivorous lemurs would significantly change the vegetation dynamics of Madagascar's ecosystems, and a high proportion of Madagascar's endemic plants would enter an extinction vortex.

Parts of southern Belize are designated as a corridor for the jaguar Panthera onca but the Maya region remains understudied. We therefore studied jaguar habitat use, activity patterns, and interactions with people in Blue Creek, a Maya village in a human-dominated tropical landscape in southern Belize. We used camera traps to detect jaguar presence, and interviews to assess local people's attitudes to and perceptions of jaguars. We recorded 28 independent photographic events during 1,200 camera-trap nights (i.e. a relative abundance index of 2.3 jaguars per 100 trap days). Seven individual jaguars were identified. Jaguars preferred lowland broad-leaf tropical forest and were detected more often during daylight, in contrast to findings from previous studies. Attitudes towards jaguars were largely positive: 88% of respondents (n = 48) did not fear jaguars living around the village, and 81% understood the positive effect that jaguars have on the ecosystem. Although 92% of respondents reported seeing a jaguar within the previous 2 years, attacks on livestock in the village were rare, with only two occurrences in the previous 3 years. Ecotourism has grown rapidly in Belize in recent years, and Blue Creek is home to several natural tourist attractions and an eco-lodge that brings tourists, school groups, and researchers to the village. Ecotourism has provided an economic incentive for village investment in conservation, and 94% of respondents stated that preservation of wildlife, including jaguars, was beneficial to their well-being.

Many global efforts to decrease deforestation have focused on community-based conservation programmes to reach their goals. However, many such programmes are lacking a potentially helpful population, women. We employed key-informant interviews to examine attitudes towards, and barriers to, women's participation in a community-based conservation programme prior to implementation. We conducted 47 semi-structured interviews in January 2015 in communities adjacent to the Vaca Forest Reserve in the Cayo District of Belize. Results indicated that the benefits of involving women in community-based conservation activities included them learning more about the forest and conservation, transferring this knowledge to their family and community, and helping the environment. Some possible barriers to participation included lack of time and motivation to participate. However, there were notable differences between men's and women's responses relating to women's available time and their willingness to participate, with men not mentioning time as a barrier and stating that women would need more motivation to participate. The results will be used to work with local women to collaboratively develop and implement a community-based conservation programme around the Vaca Forest Reserve.

Extinction is the complete loss of a species, but the accuracy of that status depends on the overall information about the species. Dracaena umbraculifera was described in 1797 from a cultivated plant attributed to Mauritius, but repeated surveys failed to relocate it and it was categorized as Extinct on the IUCN Red List. However, several individuals labelled as D. umbraculifera grow in botanical gardens, suggesting that the species’ IUCN status may be inaccurate. The goal of this study was to understand (1) where D. umbraculifera originated, (2) which species are its close relatives, (3) whether it is extinct, and (4) the identity of the botanical garden accessions and whether they have conservation value. We sequenced a cpDNA region of Dracaena from Mauritius, botanical garden accessions labelled as D. umbraculifera, and individuals confirmed to be D. umbraculifera based on morphology, one of which is a living plant in a private garden. We included GenBank accessions of Dracaena from Madagascar and other locations and reconstructed the phylogeny using Bayesian and parsimony approaches. Phylogenies indicated that D. umbraculifera is more closely related to Dracaena reflexa from Madagascar than to Mauritian Dracaena. As anecdotal information indicated that the living D. umbraculifera originated from Madagascar, we conducted field expeditions there and located five wild populations; the species’ IUCN status should therefore be Critically Endangered because < 50 wild individuals remain. Although the identity of many botanical garden samples remains unresolved, this study highlights the importance of living collections for facilitating new discoveries and the importance of documenting and conserving the flora of Madagascar.

Throughout its range in Latin America the jaguar Panthera onca is threatened by habitat loss and fragmentation, and conflict with humans. Protected areas in Panama harbour some of the last remaining suitable habitat for jaguars and are vital to conservation. However, no previous studies had assessed which factors in particular affect the tolerance of rural Panamanians towards jaguars and National Park conservation, which is important to jaguar persistence. Whether these factors are consistent with previous research on human–carnivore coexistence is unclear. To address this we estimated the number of instances of depredation of cattle by jaguars, and assessed attitudes and perceptions of rural Panamanians. We conducted semi-structured interviews in two disparate study areas: Cerro Hoya National Park and Darién National Park. Depredation events were more frequent in the latter, but only residents of the former reported conflict between people and coyotes Canis latrans. Positive perceptions of jaguars and National Parks, and criticism of park management, increased with level of education and land ownership. Men were more open to receiving help on their farms to mitigate impacts of jaguars, and more tolerant of the presence of jaguars, than women. Residents from both study areas indicated high appreciation for their respective National Parks. We provide recommendations to improve community outreach and education initiatives, and suggest priority areas for future mitigation efforts concerning human–jaguar interactions in Panama.

The bush dog Speothos venaticus is a medium-sized Neotropical canid. It is considered to be rare and its biology and population parameters are still poorly understood. The Amazon is one of the main strongholds of this species and is important for maintaining viable populations, as the region still holds extensive tracts of pristine habitat. We gathered field data from camera-trap studies throughout the Brazilian Amazon to estimate the relative abundance of the species and gain an understanding of its rarity, and how this compares with estimates from other vegetative formations and for sympatric hypercarnivores. We focused on three pristine or partially disturbed sites and one fragmented site. The estimated relative abundance of the species was 0.060–0.185 individuals per 100 trap-days, confirming that the species is rare. The bush dog's abundance in the Amazon is equivalent to that in all other areas outside the Basin. The mean group size recorded was c. 2.5 individuals. There were no differences in group sizes between forests in the Amazon and in other regions of Central America; however, there were significant differences between forests and open habitats. A combination of competition/predation, habitat structure/integrity, and disease may be acting synergistically in determining the abundance and rarity of bush dogs.

The plant Mollinedia stenophylla Perkins (Monimiaceae) is endemic to southern Brazil and, until 2015, had not been seen for 122 years. We located a single population of the species on the margin of a watercourse in the mountainous region of Rio de Janeiro state. We describe the location of the species, comment on its morphology, ecology and conservation, assess its conservation status, propose conservation measures, and discuss the potential value of local action plans for this and other narrow endemic plant species. Mollinedia stenophylla has whorled leaves, clonal reproduction and a low height, unusual traits in the genus Mollinedia. Using the IUCN Red List criteria we assess the species as Critically Endangered. This example highlights the importance of investing time in plant surveys and taxonomy, especially in megadiverse countries such as Brazil.
