Conservation regulations aimed at restricting resource use are commonly used to manage and protect natural resources but their implementation depends on the compliance of resource users. The design of effective regulations should be informed by an understanding of the factors that affect compliance, considering contextual socio-economic information. Changes have been implemented in the national legislation protecting marine turtles in the Cape Verde archipelago, where historical and recent records indicate heavy human predation pressure on nesting and foraging marine turtles. We present an assessment of levels of illegal harvesting and consumption of marine turtle products on two of the islands, Boa Vista and Santiago, and an analysis of their potential drivers. Key stakeholders were interviewed to investigate the perceived impact of the main interventions employed in Cape Verde to reduce illegal harvesting, trade and consumption of marine turtles. Despite an apparent decrease in harvesting and consumption, our results suggest there has been a shift from subsistence harvesting to trade in Boa Vista. The existence of laws to protect marine turtles was perceived as a deterrent to harvesting, and awareness campaigns and a lack of availability were perceived as reasons for the decrease in consumption in Boa Vista and Santiago, respectively. Aiming to inform ongoing discussions, we recommend a multi-targeted approach focusing on both suppliers and consumers to magnify conservation effectiveness. Regular impact evaluation focusing on harvest and consumption is needed to improve the design of regulations and inform policy decision making.

A range of endemic and protected vertebrate species from Madagascar are threatened by the demand for bushmeat. We report on the number of discarded carapaces from illegally killed Critically Endangered radiated tortoises Astrochelys radiata in an urban centre in south-west Madagascar. Through covert monitoring of public rubbish dumps we observed 1,913 carapaces during July 2010–January 2014. There was notable spatial and temporal variation, with some evidence of peaks in carapace dumping during May–June and October–December. A single rubbish dump near the artisanal fishery landing beaches accounted for 93% of the observed carapaces.

Ninety-five percent of orchid species associated with fynbos shrublands of South Africa's Cape Floristic Kingdom have been assessed for the IUCN Red List, yet aspects of their demography and population biology remain poorly understood. We conducted a 6-year demographic study of the Critically Endangered Disa procera, a cryptic, terrestrial species from South Africa with a global population of c. 50 individuals known from a single location. We aimed to provide management recommendations that would facilitate its persistence. Our findings indicate that the population of D. procera is larger than previously thought, and the species occurs at two distinct locations. These orchids exhibit high interannual variation in population size and turnover of individuals, potentially indicative of a species with a short life span, and still meet the criteria for Critically Endangered status. The species benefits from disturbances, such as brush cutting along trails, or fire, which open up clearances in the vegetation. However, physical damage to plants during their aboveground growing season (September–January) is particularly detrimental and should be avoided in habitat management for the species. Fire had beneficial effects at the population and individual levels and is recommended at 10–25-year intervals, outside the orchid's growing season. The species exhibited comparatively high rates of fruit set (68%), suggesting that pollination limitation does not currently constrain its performance. Its patchy distribution may, however, indicate constraints on dispersal or recruitment. We recommend that management strategies should include continued protection and monitoring of both populations, studies on pollination, habitat requirements and mycorrhizal associates, and a prescribed disturbance regime.

The Endangered Warburgia salutaris (Bertol. f.) Chiov. (Canellaceae), a sought-after medicinal plant in southern Africa, is on the verge of extinction as a result of overexploitation for illegal trade. As part of formulating a conservation strategy for the species in Swaziland we sought to determine its distribution and population status and to revise its national conservation status. Field surveys were conducted in all physiographic regions of Swaziland. Eighteen locations of species presence were found, of which 14 were new records. Three were within protected areas, and seven were in areas worthy of protection. The largest subpopulations occurred in two of the latter areas, Ngudzeni and Sitsatsaweni (351 and 230 individuals, respectively), and one unprotected area, Bulunga (250 individuals). Warburgia salutaris has a severely fragmented distribution and an area of occupancy of 192 km2. Of 700 mature individuals 38% were ring-barked and 7% felled, and some subpopulations had ring-barked juveniles. This indicates a plausible decline in number of mature individuals. Most localities in unprotected areas are eroded and invaded by alien plants, indicating a decline in habitat quality. Our findings indicate that W. salutaris should be categorized as Endangered nationally based on criteria B2ab (iii,v). Although this status implies a lower level of threat than the previous national categorization as Critically Endangered, it does not imply an improved conservation effort in the country, but rather a more accurate assessment based on more data. We have clarified the conservation status of W. salutaris in Swaziland, discovered some previously undocumented subpopulations and identified potential conservation interventions. We recommend that this information be used in setting priorities to ensure conservation of the species.

As conservation resources decline and numbers of threatened species increase, prioritizing species for conservation is increasingly important, and prioritizing based on attributes may be the most efficient approach. Despite the importance of biodiversity as a legacy to future generations, children's preferences for species attributes have never been considered. We surveyed 3rd and 5th grade students, typically 8–10 years old, in North Carolina, USA, to determine how children prioritize conservation of species based on attributes. We asked the students to rank five species attributes, allocate money to species with each attribute, and choose between each species attribute and endemism in terms of their importance for conservation. Children prioritized species that are important in nature and those whose numbers are declining over species with other attributes, whereas research suggests that adults prioritize endemic species over most other types. Our results suggest children prioritize biodiversity conservation differently from adults, and in ways that may be more conducive to biodiversity conservation in cases where endemism is not directly related to species endangerment, and we suggest the perspectives of children be considered more fully within biodiversity conservation.

A gap between research and management exists in numerous natural resource fields. This can lead to management actions that are based on experience rather than evidence and may be less effective as a result. The gap may be partly attributable to research not being relevant, timely or accessible for managers. Editorial boards of peer-reviewed journals are responsible for determining the relevance of submitted manuscripts for a journal's readership. Limited representation of natural resource managers on editorial boards may make it more difficult for journals to identify the topics and findings of most relevance for management, thus contributing to the research–management gap. We quantified the representation of natural resource managers on the editorial boards of 79 conservation and applied natural resource journals. We found that 65% of editors were affiliated with universities, 13% with research institutions, 12% with government agencies and 3% with NGOs. On average, 9% of editors were affiliated with an agency or organization responsible for managing or regulating natural resources. The proportion of managers on editorial boards did not differ significantly between natural resource fields or with journal impact factor. Potential benefits of greater integration of managers into the research and publishing process include selection of research topics with greater relevance for management, clearer statements of the management implications of research studies, and more frequent publication of research evaluating the effectiveness of management interventions. Further study is needed to evaluate whether greater participation of managers in the editorial review process may contribute to achieving these benefits.

Despite much effort to promote the conservation and recovery of threatened species, the extent of the current list of threatened vertebrates (> 7,600 species) underscores the need to develop novel communication and marketing tools to raise awareness and funding for their conservation. Although flagship species have been widely used in conservation marketing, the flagship role of extinct species has been largely overlooked and the status of lost species is rarely associated with the status of extant species facing a high risk of extinction. Some extinct species (e.g. the dodo Raphus cucullatus and the thylacine Thylacinus cynocephalus) are cultural and commercial icons and therefore familiar, and may appeal to the public as conservation flagships. We propose a wider use of extinct flagships to raise awareness for the conservation of threatened species by making a direct link between already extinct species and extant species at risk of extinction. We present examples of publicly recognized and iconic extinct species that could be used in marketing for the conservation of threatened species. These extinct species are familiar and may be readily linked to threatened species or species groups. We outline a roadmap for testing their appeal under the extinct flagship concept, through market research. If research identifies that a cognitive link is made between the fate of an extinct species (i.e. they went extinct from human causes) and what may happen to threatened species (i.e. they are at risk of extinction from human causes), extinct species may well have a wider role to play as conservation flagships.

Asian mammal species are facing unprecedented pressures from hunting and habitat conversion. Efforts to mitigate these threats often focus on charismatic large-bodied species, while many other species or even guilds receive less attention, particularly Asian wild pigs. To address this we developed a rapid questionnaire survey and administered it to relevant experts to identify the presence, population trends and conservation needs of Asia's 11 threatened wild pig species. The results highlighted geographical differences within species (e.g. the near collapse of bearded pig populations in Peninsular Malaysia yet their widespread presence on Borneo), and knowledge gaps for many endemic species of the Philippines, notably the Critically Endangered Visayan warty pig Sus cebifrons. To support field-based conservation projects, we identified 66 medium-to-large zoos in Asia, Europe and the USA that house Asian wild pigs and have applicable conservation funding schemes. Our rapid survey method, which yielded 170 wild pig records from across Asia, proved effective in filling many of the existing knowledge gaps, and may be widely applicable in assessing the status and needs of other non-flagship threatened species.

Assessing and updating the extinction risk and conservation status of species and populations is paramount to guide management strategies. Maintaining up-to-date and realistic geographical distribution maps of individual species is one aspect of this. We report an updated distribution for an Italian island endemic amphibian, the Sardinian newt Euproctus platycephalus, categorized as Endangered on the IUCN global and national Red Lists. The distribution of E. platycephalus was reassessed by means of visual surveys, questionnaires, interviews and scientific literature. The species was found over a geographical range comparable to that used for the IUCN assessment but we recorded a significantly larger number of populations (57 vs 14). There was no appreciable difference in the species’ Extent of Occurrence between 1972–1974 and 2010–2015. Area of Occupancy increased between past (1972–1974 and 1999–2000) and present (2010–2015) distribution records. Based on this updated distribution and considering that several new populations have been found, the distribution of the species may still be underestimated. Given the novel distribution data provided here and the need for new long-term demographic data, we recommend that the conservation status of E. platycephalus be reassessed. In the Italian national Red List a potential overstatement of extinction risk is evident for other amphibian species, possibly because the information used in their assessment is deficient. Considering that monitoring rare and elusive species is costly and time consuming we recommend more extensive use of multiple sources of information for Red List assessments.

Payments for ecosystem services schemes are viewed as having the potential to achieve positive biodiversity and ecosystem service outcomes and social outcomes, and they have been widely studied since their development in the 1990s. We describe the state of payments for ecosystem services in Indonesia, where nine schemes were identified, four involving water and five involving carbon. We also assess the perceptions of stakeholders (donors, government, and non-government agencies) regarding the status of such schemes in Indonesia, and their views on what factors support or constrain their development. The main factors perceived to support payments for ecosystem services schemes were easily identifiable ecosystem services and service users, and the long-term support provided by individuals or institutions that facilitate the schemes, building on existing relationships between communities and these facilitating agencies. Stakeholders identified problems relating to regulation: the lack of regulation specifically in relation to payments for ecosystem services, but also overlap and uncertainties regarding regulations. Other constraining factors identified were the lack of recognition of environmental problems amongst potential buyers, and issues of rights and tenure for local communities. With so few operational programmes to date, covering a relatively small land area, and such constraints to further development, payments for ecosystem services schemes appear to have limited scope to supply ecosystem services successfully and sustainably at scale.

Snake farming in Asia has increased over the past decade, and conservationists have expressed concerns that farms may foster overexploitation of wild populations and create legal conduits for illegally harvested wild individuals. We conducted face-to-face interviews with snake farmers in Viet Nam and China, with the aim of describing the basic models under which snakes are farmed for meat. We synthesized this information to assess the feasibility of farming snakes for human consumption, drawing conclusions about the impact of this industry on the conservation of wild snake populations. The most commonly farmed snakes include the monocled cobra Naja kaouthia, the Chinese cobra Naja atra, the oriental rat snake Ptyas mucosus and the king cobra Ophiophagus hannah. These species have life histories that are compatible with the demands of intensive livestock production, including early maturity, rapid growth rates, high reproductive output, efficient food assimilation rates and undemanding space requirements. Snake farmers appear to be capitalizing on the unique energy-efficiency of snakes to produce meat for human consumption. We conclude that the ease and profitability of farming snakes in China and Viet Nam make farming a viable substitute for harvesting wild snakes, with apparently minimal threat to wild populations. Snake farming offers a range of novel agricultural opportunities and has the potential to play a pivotal role in sustainable development.

A ratio-based logistic model developed to assess elephant harvest rates, based on a study at Nagarhole Tiger Reserve in India, was recommended as a management tool to control human–elephant conflict through culling. Considering this reserve among others violates an assumption of the logistic model: isolation. Nevertheless, assuming this violation was irrelevant, we re-evaluated the model, with minor modifications, for the neighbouring Mudumalai Tiger Reserve, where we used data from 13 elephant Elephas maximus population surveys to derive bootstrapped sets of population ratios, and mortality records. We generated arrays of harvest regimes and examined which ratio outputs were closest to the bootstrapped ratios. Our results indicated that (1) model outputs corresponded best with the Mudumalai population structure when harvest regimes were extreme and unlikely, (2) there were significant differences in population structure and harvest regimes between Nagarhole and Mudumalai, and (3) only 49% of adult male deaths predicted by model outputs were recorded in official governmental records. The model provides significantly different results among reserves, which invalidates it as a tool to predict change across the entire elephant population. Variability in survey data and inaccuracies in transition probabilities are sufficiently large to warrant caution when using them as a basis for deterministic modelling. Official mortality databases provide a weak means of validation because poaching incidents are poorly recorded. We conclude that the model should be based on validated transition probabilities and encompass the entire regional population.

Protected areas across the range of the African savannah elephant Loxodonta africana are increasingly being surrounded and isolated by agriculture and human settlements. Conflicts between people and crop-raiding elephants regularly lead to direct reprisals and diminish community support for conservation. We report on field trials in northern Tanzania that employed a new, humane way for wildlife managers to move elephants away from conflict zones, from distances of > 100 m, thereby enhancing the safety of wildlife managers, farmers and elephants. We deployed 10 unmanned aerial vehicles (drones) piloted by five trained teams of wildlife managers in the Tarangire–Manyara and Serengeti ecosystems. Game Scouts deployed the drones opportunistically during crop-raiding events at the peak of the maize ripening period in 2015 and 2016. In 100% of trials (n = 51) elephants responded to the presence of a drone by departing rapidly from crop fields (n = 38) and settlements (n = 13). The cost of five teams responsible for 617 km2 in Tarangire–Manyara was estimated to be USD 15,520 for 1 year, and all drones remained operational for the duration of the study. The initial success of this tool warrants further testing of the utility of small unmanned aerial vehicles as part of the toolbox for wildlife managers and communities dealing with high levels of conflict with wildlife.

Little is known about the Endangered Grevy's zebra Equus grevyi in far northern Kenya, where the species exists in small, isolated populations at the periphery of its range. Understanding the threats facing this species is a prerequisite for effective conservation planning but its rarity makes obtaining accurate information challenging. We set out to establish the current status of, and attitudes towards, Grevy's zebra in northern Kenya using local knowledge as the primary source of information. Pastoralists perceived Grevy's zebra to be in decline as a result of drought, lack of pasture and water, and hunting for consumptive use. There was also evidence of competition with livestock. Attitudes towards Grevy's zebra were predominantly positive, influenced by a range of perceived benefits of living alongside the species, and an absence of severe costs. Coupled with evidence of local conservation efforts in several locations, this is a positive starting point for community-based conservation.

We assessed the impacts of crop raiding by wild mammals on the livelihoods of smallholding farmers in south-western Ethiopia. Data were generated through participatory field mapping, interviews and focus groups. The results indicated that wild mammals, mainly olive baboons Papio anubis and bush pigs Potamochoerus larvatus, were raiding most crops cultivated in villages close to forests. In addition to the loss of crops, farmers incurred indirect costs in having to guard and cultivate plots far from their residences, sometimes at the expense of their children's schooling. Raiding also undermined farmers’ willingness to invest in modern agricultural technologies. Various coping strategies, including guarding crops and adapting existing local institutions, were insufficient to reduce raiding and its indirect impacts on household economies to tolerable levels, and were undermined by existing policies and government institutions. It is essential to recognize wild mammal pests as a critical ecosystem disservice to farmers, and to identify ways to mitigate their direct and indirect costs, to facilitate local agricultural development and livelihood security, and integrate wildlife conservation and local development more fully in agriculture–forest mosaic landscapes.

Although not categorized as threatened on the IUCN Red List, the African forest buffalo Syncerus caffer nanus is declining across its range. In Nigeria its distribution, abundance and status are virtually unknown. We conducted interviews with experienced hunters, and field surveys (linear and recce transects), to study the buffalo's distribution and ecology in the montane forests of Cross River State. General linear modelling indicated that the number of individuals varied significantly across survey areas and habitat types but not with the survey period, and there was no study area × study period interaction. Buffalo were found most commonly in mature and secondary forests. Given the species’ scattered distribution, fragmentation of its habitat, and the relatively low numbers observed, Nigerian populations require a separate, regional categorization on the IUCN Red List.

Madagascar is an important foraging ground for marine turtles in the Western Indian Ocean, yet the status of the country's nesting aggregations remains poorly documented. We assess the current status and trend in nesting throughout Madagascar, including data recorded by a community-based monitoring project in the Barren Isles (western Madagascar). We contextualize the findings in comparison with data from Madagascar's closest neighbouring states. Reports indicate that nesting levels have declined at many coastal sites, with no known recordings since 2000 at > 40 nesting sites. We estimate there are a minimum of 1,200 nests per year in Madagascar, with the largest recorded nesting aggregation (< 1,000 nests per year) found on islands off the west and northern coasts. The majority of nesting aggregations, including those recorded by the community-based monitoring project in the Barren Isles, are relatively small, in the order of < 50 nests per year, yet they are potentially important sources of regional genetic diversity. Nesting on many of the islands (e.g. Tromelin, Europa) around Madagascar has increased over the last 20 years, despite the fact that thousands of turtles probably originating from these sites are taken by fishers in the waters of Madagascar annually. We discuss the importance of protecting small nesting populations, and how community-based monitoring could be an important tool for conserving remote and vulnerable populations and building capacity for natural resource management.

Reintroduction practitioners must often make critical decisions about reintroduction protocols despite having little understanding of the reintroduction biology of the focal species. To enhance the available knowledge on the reintroduction biology of the warru, or black-footed rock-wallaby Petrogale lateralis MacDonnell Ranges race, we conducted a trial reintroduction of 16 captive individuals into a fenced predator and competitor exclosure on the An̲angu Pitjantjatjara Yankunytjatjara Lands in South Australia. We conducted seven trapping sessions and used radio-tracking and camera traps to monitor survival, reproduction and recruitment to the population over 36 months. Blood samples were collected pre-release and during two trapping sessions post-release to assess nutritional health. The survival rate of founders was 63%, with all losses occurring within 10 weeks of release. Post-release blood biochemistry indicated that surviving warru adapted to their new environment and food sources. Female warru conceived within 6 months of release; 28 births were recorded during the study period and 52% of births successfully recruited to the population. Our results suggest that captive-bred warru are capable of establishing and persisting in the absence of introduced predators. However, the high mortality rate immediately post-release, with only a modest recruitment rate, suggests that future releases into areas where predators and competitors are present should use a trial approach to determine the viability of reintroduction. We recommend that future releases of warru into unfenced areas include an intensive monitoring period in the first 3 months post-release followed by a comprehensive long-term monitoring schedule to facilitate effective adaptive management.

The giant anteater Myrmecophaga tridactyla is categorized as Vulnerable on the IUCN Red List, and is extinct in several locations as a result of environmental pressures. We present the first records of the giant anteater in the largest continuous expanse of the Atlantic Forest biome, in southern Brazil, highlighting its occurrence in the highlands of the Serra do Mar mountain range. During a camera-trapping survey of medium and large mammals we obtained two records of the species, one in 2013 and the other in 2014. These records from dense rainforest highlands indicate the importance of this environment for the giant anteater and highlight these areas as possible foci for future studies of the species. In addition, we present a review of the species’ occurrence in protected areas in Brazil, to provide a resource for the conservation of this species and for future re-evaluations.
