The remaining Indochina population of the Critically Endangered Bengal florican Houbaropsis bengalensis breeds in the floodplain of Cambodia's Tonle Sap Lake. The population has declined substantially but survival rates have not been published previously. Survival could potentially be reduced by the planned construction of high-tension power transmission lines that may begin in 2016. Using data from 17 individuals monitored by satellite transmitters over 4 years we estimated the annual adult survival rate to be 89.9% (95% CI 82.2–97.6%), which is comparable to that of other bustards. Interrogation of movement paths revealed that for the 13 individuals for which we had sufficient data for non-breeding seasons, all annual migration routes between breeding and non-breeding areas crossed the proposed route of the transmission line. The route also impinged on the margins of one important and one minor breeding concentration. A review of bustard collision rates confirmed the vulnerability of bustards to power lines, and the proposed development therefore presents an additional threat to the future of this species in Indochina.

Understanding community attitudes towards protected areas is of great importance because these attitudes are inherently linked to the long-term existence and effectiveness of protected areas. We assessed the factors that influence community attitudes towards Mole and Digya National Parks in Ghana. During June–August 2015 we conducted interviews with 346 randomly selected households, using a semi-structured questionnaire. We found that attitudes towards the protected areas were positive, with Mole residents being more positive than Digya residents. Analyses revealed that community attitudes were largely influenced by the perceived costs and benefits of the protected area, household size, occupation, level of education, and awareness of or participation in livelihood projects. The findings suggest that increasing the benefits from protected areas and minimizing the costs on fringe communities fosters positive attitudes towards the concept of protected areas and conservation in general. Additionally, perceptions of protected areas are likely to be more positive when management interventions are tailored for local communities as opposed to the adoption of universal, unspecific interventions.

Wild ungulates, and particularly deer, can cause severe damage to commercial plantations, resulting in reduced tolerance of their presence by forestry producers. The marsh deer Blastocerus dichotomus, categorized as Vulnerable on the IUCN Red List, is declining throughout South America. A population of c. 500 individuals survive within a matrix of commercial plantations in the lower delta of the Paraná River, the southernmost stronghold for the species. Local forestry producers usually report that damage to plantations is attributable to marsh deer, thus justifying persecution of the species. Seventy-six forestry producers (representing c. 33% of the total plantation area of the lower delta) were interviewed using a semi-structured questionnaire to assess perceived levels of tree damage, associated economic losses, and attitudes towards the deer. Simultaneously, plantation stands were surveyed to quantify the actual tree damage caused by this ungulate. Seventy-six percent of producers reported damage to trees by deer (i.e. browsing, fraying caused by antler rubbing) but most of them perceived low levels of damage per property (median < 0.2%), with negligible economic effects. However, 5% of producers (all of them with ≤ 2 km2 in production, usually family enterprises) perceived high levels of damage and economic losses, and supported deer hunting as a management option. Field surveys indicated that damage caused by deer could be more severe than perceived by producers, although spatially confined within the landscape. Monitoring of damage perception by forestry producers, and compensation schemes to assist small producers are necessary for adequate management of this threatened marsh deer population.

Protecting seabirds is a global conservation priority given that 29% of seabird species are threatened with extinction. One of the most acute threats to seabirds is the presence of introduced predators, which depredate seabirds at all life stages, from eggs to adults. Consequently, eradication of invasive predators has been identified as an effective and commonly used approach to seabird conservation. Seabird recovery following the eradication of predators is influenced by complex and interacting environmental and demographic factors, and there are gaps in our understanding of species-specific responses. We reflect on the recovery of seabirds on islands cleared of predators, drawing on the equilibrium theory of island biogeography, and synthesize key influences on recovery reported in the literature. We present a regionally specific case study on the recovery of seabird colonies (n = 98) in the Hauraki Gulf, New Zealand, which is a hotspot of seabird diversity (27 species), with a long history of eradications of invasive predators. We found that on islands cleared of predators seabirds recover over time, and such islands have more diverse seabird assemblages than islands that never had predators. Recovery appears to be influenced by a suite of site- and species-specific factors. Managers may assume that given enough time following eradication of predators, seabirds will recolonize an island. Although time is a factor, proximity to source populations and human activities has a significant effect on recolonization by seabirds, as do demographic traits, colonizing ability and habitat suitability. Therefore, integrating expected site and species-specific recovery responses in the planning of eradications should help guide post-eradication management actions.

Biodiversity conservation outside protected areas requires cooperation from affected communities, hence the extensive discussions of trade-offs in conservation, and of a so-called new conservation that addresses human relations with nature more fully. Human–wildlife conflict is one aspect of those relations, and as land use intensifies around protected areas the need to understand and manage its effects will only increase. Research on human–wildlife conflict often focuses on individual species but given that protecting wildlife requires protecting habitat, assessments of human–wildlife conflict should include subsidiary impacts that are associated with ecosystem conditions. Using a case study from Laikipia, Kenya, where conservation outside protected areas is critical, we analysed human–wildlife conflict from a household perspective, exploring the full range of impacts experienced by community members on Makurian Group Ranch. We addressed questions about four themes: (1) the relationship between experienced and reported human–wildlife conflict; (2) the results of a high-resolution assessment of experienced human–wildlife conflict; (3) the relative impact of high-frequency, low-severity conflict vs high-severity, low-frequency conflict; and (4) the effect of experienced conflict on receptivity to the conservation narrative. Our results show that high-frequency, low-severity conflict, which is often absent from reports and discussion in the literature, is a significant factor in shaping a community's perception of the cost–benefit ratio of conservation. Local, ongoing, high-resolution monitoring of human–wildlife conflict may facilitate more realistic and effective incorporation of the experienced impacts of human–wildlife conflict in conservation planning and management. Such monitoring could help to define locally appropriate trade-offs in conservation and thereby improve conservation outcomes.

In 2001 sport hunting was reintroduced in Uganda around Lake Mburo National Park, and in 2008 at Kabwoya and Kaiso-Tonya Game Management Area, to derive economic benefits for communities and thus reduce human–wildlife conflict and change communities’ attitudes towards wildlife. We used the policy arrangement approach to analyse and compare the development of the two sport hunting policy arrangements. Through interviews and document review we learned that the arrangement at Lake Mburo changed considerably over time, whereas that at Kabwoya remained relatively stable. The two policy arrangements started with small constellations of actors but turned out to be complex arenas, mainly involving disagreement regarding the benefits. Land ownership proved to be a crucial factor in explaining the differences between the arrangements. Our results also show that benefits do not change communities’ attitudes towards conservation, thus questioning incentive-based policies for conservation. We argue for a careful analysis of the complex social, cultural and political contexts in which conservation and development policies are implemented, to better understand their outcomes.

The incidence of human–crocodile conflict is increasing, and fear of injury and loss of life is affecting public and political support for crocodile conservation. We studied conflicts between people and estuarine crocodiles Crocodylus porosus across socio-economic dimensions, using a spatio-temporal database. We collected data on 127 crocodile attacks that occurred during 2000–2013, through questionnaires including open- and close-ended questions, administered in 30 villages of five blocks of the Indian Sundarban. Most of the attacks (42%) occurred during winter (December–February), followed by the early monsoon (May–July; 27%). Almost 80% of victims were prawn seed collectors and were 11–50 years old, and 61.16% of victims died as a result of the attacks. Female victims accounted for a higher percentage of deaths (55.12%) than male victims (44.88%). Crocodile attacks were more common in the daytime than at night, with 76.35% of the killings occurring during 08.00–17.00. Most of the cases were recorded from Gosaba (34%), followed by Patharpratima (25.24%) and Namkhana (18.45%) blocks. The mean number of incidents per year was 9.07, with vulnerability and mortality rates of 0.07 and 0.04, respectively, per 10,000 persons. Existing management practices are insufficient to eliminate the risk of crocodile attacks and ensure the conservation of the Sundarban ecosystem. A comprehensive management plan for reducing dependency on forest resources is needed to minimize human–crocodile conflict.

The orang-utan Pongo spp. is protected by national and international legislation, yet populations continue to decline. Many reports implicate local people in the poaching and illegal trade in orang-utans, yet community participation has been promoted as an alternative conservation strategy. To explore how community-based orang-utan conservation could be developed, we conducted a study to understand informal institutions, particularly local people's perceptions, traditional beliefs, taboos, norms and knowledge, related to orang-utan conservation within and around the wetlands of Danau Sentarum. The majority of Dayak communities interviewed practised traditional taboos, which supported the protection of orang-utans and their habitat. Statistical analysis using generalized linear modelling indicated that more orang-utan nests were found in areas with both good habitat condition and strong informal institutions. Despite applying traditional systems that are similar to conservation, local people have negative perceptions about the term ‘conservation’. We describe the underlying causes of these negative perceptions and highlight their implications for conservation programmes and policies. We conclude that conservation of orang-utans and other species should not focus on single species but on maintaining social and natural capital, cultural diversity and ecological functions at various institutional levels and across geographical scales.

The Vulnerable clouded leopard Neofelis nebulosa is believed to be one of the most threatened felid species in Nepal. Information on its status and population size in the country mostly comprises crude estimates. We compiled information on the species’ status and distribution from published papers, grey literature, camera-trap images, direct observations, pelt, zoo and museum records, wildlife seizures and verified newspaper reports. All confirmed records of the species (three museum specimens, one dead specimen, 13 live records (including from camera traps), and 14 pelts) were from eastern and mid-central Nepal. Two unconfirmed reports from the western and far-western regions of the country need to be verified. Although the status of the species is still uncertain, the frequency of confirmed and unconfirmed reports and the extent of the area of occurrence indicate that it is not as rare as previously assumed. The main threats to the species are habitat loss and illegal wildlife trade.

Feral swine Sus scrofa have been implicated as a major threat to sensitive habitats and ecosystems as well as threatened wildlife. Nevertheless, direct and indirect impacts on threatened species (especially small, fossorial species) are not well documented. The decline of the U.S. federally endangered reticulated flatwoods salamander Ambystoma bishopi, categorized as Vulnerable on the IUCN Red List, has been rapid and there are few remaining breeding locations for this species. The flatwoods salamander depends on complex herbaceous vegetation in all life stages, including eggs, larvae and adults. Historically sets of hog tracks have been observed only occasionally in the vicinity of monitored reticulated flatwoods salamander breeding wetlands, and damage to the wetlands had never been recorded. However, during the autumn–winter breeding season of 2013–2014 we observed a large increase in hog sign, including extensive rooting damage, in known flatwoods salamander breeding wetlands. Our objective was to assess the amount of hog sign and damage in these wetlands and to take corrective management actions to curb additional impacts. Of 28 wetlands surveyed for hog sign, presence was recorded at 68%, and damage at 54%. Of the 11 sites known to be occupied by flatwoods salamanders in 2013–2014, 64% had presence, and 55% had damage. We found that regular monitoring of disturbance in wetland habitats was a valuable tool to determine when intervention was needed and to assess the effectiveness of intervention. Habitat damage caused by feral hogs poses a potentially serious threat to the salamanders, which needs to be mitigated using methods to control and exclude hogs from this sensitive habitat.

One of the major threats to tropical forests throughout the world is the frequency and intensity with which local people use forests for subsistence. Kakamega Forest in Kenya is one such forest, in which fuelwood harvest is a primary use. The Kenya Forest Service and Kenya Wildlife Service have tried to regulate subsistence harvesting in this forest. However, high human population density (c. 542 people per km2) and extreme poverty leave local people little choice but to use forest resources to survive. We investigated patterns of wood use by people across Kakamega Forest. Our results indicate that wood harvesters prefer indigenous as opposed to non-indigenous wood, as the former sells for a premium price. Harungana madagascariensis and Psidium guajava were the most harvested indigenous and non-indigenous woods, respectively. Our data suggest that because market economies seem to drive forest use, perhaps they can be used to incentivize forest conservation. Proper integration of economic forest conservation interventions, economic diversification, and effective forest management are needed to protect Kakamega Forest.

We examined attitudes towards forest and wildlife among Rabha, Bodo and Rajbongshi communities from three villages in the Chakrashila Wildlife Sanctuary of western Assam, India. The study was conducted through open-ended and structured interviews, focus group discussions, and participatory rural appraisal. The respondents identified availability of forest products, biodiversity conservation and the aesthetic beauty of the forest as the major justifications for the establishment of Chakrashila as a protected area. They also believed that people and wildlife could coexist peacefully, although some respondents did not have a cordial relationship with Forest Department staff. Most respondents were favourably disposed towards the golden langur Trachypithecus geei because it did not harm anybody or damage crops, and because of its shining coat and its exalted status in their religious beliefs. They were antagonistic towards the rhesus macaque Macaca mulatta because of its crop-raiding habits, although they were averse to killing it. Most respondents did not want to relocate because they lacked skills and resources and had associations with the forest, where they maintained sacred groves and observed taboos on hunting and plant resource extraction. Thus, the attitudes of the communities were governed not only by their material needs and priorities but also by their deep-rooted cultural–religious bond with the forest. These matters would benefit from being incorporated into forest management strategies in developing countries.

As with many islands, Christmas Island in the Indian Ocean has suffered severe biodiversity loss. Its terrestrial lizard fauna comprised five native species, of which four were endemic. These were abundant until at least the late 1970s, but four species declined rapidly thereafter and were last reported in the wild between 2009 and 2013. In response to the decline, a captive breeding programme was established in August 2009. This attempt came too late for the Christmas Island forest skink Emoia nativitatis, whose last known individual died in captivity in 2014, and for the non-endemic coastal skink Emoia atrocostata. However, two captive populations are now established for Lister's gecko Lepidodactylus listeri and the blue-tailed skink Cryptoblepharus egeriae. The conservation future for these two species is challenging: reintroduction will not be possible until the main threats are identified and controlled.

Management and monitoring of community-based protected areas in Madagascar remain challenging because of a lack of financial, human and technical resources, and capacity. At Lake Alaotra, conversion of marshland for rice cultivation and a lack of effective habitat protection have pushed the locally endemic Alaotra gentle lemur Hapalemur alaotrensis to the brink of extinction. The highest density of the species is found in the locally managed Park Bandro, a high-priority conservation zone within the Lake Alaotra New Protected Area. We evaluated local awareness and perceptions of Park Bandro, and discussed preferred management options with local communities. Two questionnaire surveys were carried out, one with 180 participants at six sites around the lake and marsh, and another with 50 participants in the village adjacent to Park Bandro. The majority of participants knew of the existence of Park Bandro but most did not know its purpose or size. Values and perceptions of local communities were influenced by occupation and distance to the Park, with fishers being most aware of the Park. We found that local people had a high level of environmental awareness and were willing to discuss zonation and alternative resource management strategies as long as these activities could provide a tangible livelihood benefit. Lack of awareness among local resource users regarding the purpose and status of protected areas such as Park Bandro is a challenge that needs to be addressed, and one that is relevant for environmental education and management of protected areas throughout Madagascar.

Livestock depredation has particular significance in pastoral societies across the Himalayas. The dynamics of depredation by the snow leopard Panthera uncia and wolf Canis lupus were investigated by means of household surveys in the Hushey Valley, in the Karakoram Mountains of Pakistan. During 2008–2012 90% of the households in the valley lost livestock to snow leopards and wolves, accounting for 0.8 animals per household per year. The cost of depredation per household was equivalent to PKR 9,853 (USD 101), or 10% of the mean annual cash income. The majority (41%) of predation incidents occurred in summer pastures, predominantly at night in open spaces. Of the total number of predation incidents, 60% were attributed to snow leopards and 37% to wolves; in 3% of cases the predator was unknown. As an immediate response to predation the majority of the local people (64%, n = 99) opted to report the case to their Village Conservation Committee for compensation and only 1% preferred to kill the predator; 32% did not respond to predation incidents. The perceived causes of predation were poor guarding (77%), reduction in wild prey (13%), and livestock being the favourite food of predators (10%). The most preferred strategies for predator management, according to the respondents, were enhanced guarding of livestock (72%), followed by increasing the availability of wild prey (18%), and lethal control (10%). Livestock depredation causing economic loss may lead to retaliatory killing of threatened predators. For carnivore conservation and livestock security in this area we recommend improved livestock guarding through collective hiring of skilled shepherds and the use of guard dogs.

Traditional activities that potentially threaten biodiversity represent a challenge to conservationists as they try to reconcile the cultural dimensions of such activities. Quantifying the impact of traditional activities on biodiversity is always helpful for decision making in conservation. In the case of snake charming in Morocco, the practice was introduced there 500 years ago by the religious order the Aissawas, and is now an attraction in the country's growing tourism industry. As a consequence wild snake populations may be threatened by overexploitation. The focal species for snake charming, the Egyptian cobra Naja haje, is undergoing both range and population declines. We estimated the level of exploitation of snakes based on field surveys and questionnaires administered to Aissawas during 2003–2014, and compared our results with those of a study conducted 25 years previously. Aissawas use four venomous and four non-venomous species for snake charming and we estimate they harvest a minimum of 4,500 individuals annually, mostly venomous snakes. For exhibition purposes they selectively remove the largest specimens from the wild (i.e. those that could have the highest reproductive output). Compared to the previous data, we detected (1) a reduction in the number of species collected, (2) an increased distance to collecting fields, and (3) an increase in the market price for snakes, after correction for accumulated inflation, signifying a higher demand for these animals.

Although biodiversity has value for the global community, biodiversity protection often imposes costs on local communities. Correcting this misalignment requires appropriate local incentives. Conservation agreements (i.e. negotiated transactions in which conservation investors finance social benefits in return for conservation actions by communities) are a form of direct incentive. The results of this approach depend on effective monitoring of ecological and socio-economic impacts to verify that environmental and development objectives are met. Monitoring is also needed to verify that parties to the agreements comply with their commitments. Ecological monitoring results for agreements between Conservation International and communities in the Colombian Amazon show positive conservation impacts. These agreements are designed to protect forest areas and two threatened fish species that are important to local livelihoods and have high commercial value. We show how effective monitoring is essential for identifying long-term sustainability options. Lessons learned from this project inform reflection on emerging frameworks for scaling up the approach to the national level.

The proposed legalization of international trade in rhinoceros horn is a hotly debated topic. South Africa is home to a large proportion of Africa's black Diceros bicornis and white rhinoceroses Ceratotherium simum populations. Private owners are custodians of c. 25% of the country's rhinoceroses, and the introduction of legal trade in horn harvested from live rhinoceroses may therefore have significant implications for the private conservation industry. This study explores perceptions of legal trade in rhinoceros horn, and its potential implications for reserve management, among rhinoceros owners and conservation practitioners from private game reserves in the Eastern Cape Province of South Africa. Twenty-five semi-structured interviews were conducted with key informants from 17 private game reserves (c. 37% of the total number of reserves with rhinoceroses). Whereas rhinoceros owners were mostly in favour of trade, opinion among non-owners was more nuanced. Owners expressed more interest in trading in live rhinoceroses, and stockpiled horn from natural mortalities, than in sustainably harvesting rhinoceros horn for trade. Informants therefore predicted that they would not change their practices significantly if the trade were legalized. However, most informants had little confidence that CITES would lift the trade ban. The perspectives of private reserve owners and managers should be taken into account in South African and international policy discussions relating to the legal trade in rhinoceros horn.

The Antillean manatee Trichechus manatus manatus is a cryptic mammal that inhabits, among other areas, murky rivers and estuaries of Central and South America. The difficulty in detecting and counting manatees is an obstacle to monitoring their population status, as traditional count sampling is unsuitable. We conducted a quantitative analysis of the distribution and abundance of the manatee across its known range in the rivers and estuaries of French Guiana, based on data from a range-wide line transect visual survey combined with a side-scan sonar survey, identification of feeding sites, and silent observations at fixed points. A total effective effort of 248 hours and 1,129 km of boat survey was completed. We used two relative abundance indices: the combined encounter rate, which combines encounters per km from either visual or side-scan sonar surveys, and the global detection index, which is defined as the sum of all evidence per unit time. Manatees were detected in all nine study units. Niche modelling was used to analyse the space selection by manatees, and helped to detect differential use of habitats according to the season. The model predicted that coastal areas are used more extensively during the dry season. In the absence of better techniques to detect wild manatees in complex habitats this monitoring protocol may be relevant and replicable in hydrological systems where manatee detectability is constrained by biogeographical characteristics.

Illegal hunting is a widespread problem, with motivations varying across regions. We investigated the patterns and reasons for hunting in Afghanistan, where it is generally illegal but pervasive in the wake of decades of civil war. To assess motivations for hunting, firstly we conducted a systematic review of the literature, extracting information from 32 studies that discuss the relative importance of various reasons for hunting in Afghanistan; we analysed findings from these studies using the meta-analytic method of vote-counting. Secondly, using face-to-face interviews or a web-based questionnaire, we surveyed key informants in Afghanistan about the motivations identified in the literature. We obtained responses from 57 people familiar with hunting, including government officials, vendors in wildlife markets, and hunters. Findings from the meta-analysis and the survey were broadly consistent, both identifying the market for fur and other by-products as one of the most important motivations for hunting. However, much of the published literature focuses on hunting of carnivores, and emphasizes retaliation as a motivation for hunting. Key informants were more likely to cite subsistence consumption and to suggest that providing education and livelihood alternatives would reduce hunting. Our results highlight the importance of a multi-pronged policy response that recognizes variation in motivations for hunting different species.
