The processes that threaten 240 Indonesian threatened plants were identified and categorized based on a comprehensive review of the published literature and elicitation of information from experts. Intrinsic biological factors and habitat loss are the major causes of plant endangerment in Indonesia (affecting 83 and 82% of species respectively), followed by overexploitation (64%) and natural factors (6%). The dominant threats vary between major plant groups, with habitat loss being particularly important for palms and trees, and biological factors important for orchids. For all studied plant species three sets of inter-related threatening processes (threat syndromes) were identified that differed among the major plant groups. By identifying and evaluating the processes that threaten plants in Indonesia we provide knowledge to guide their future conservation.

The aims of this work were to verify the distribution and population size of Lamyropsis microcephala (Asteraceae), characterize its habitat, assess its conservation status and initiate conservation measures for this Critically Endangered species. Distribution was determined by field surveys and mapping. To estimate population size and density 81 permanent monitoring plots were randomly established. Ex situ conservation measures were activated by harvesting and appropriate storage of seed. We confirmed the presence of L. microcephala at two previously known sites and found it in two previously unknown localities. The areas in which the species occur vary from 200 to 240,000 m2, at altitudes of 1,450–1,820 m, on slopes of 15–45° with aspects from north to west. The estimated number of ramets per population varied from c. 2,000 to c. 2,000,000, with a mean density of 8.29 ± SD 14.3 to 10.33 ± SD 10.05 ramets m-2. Our findings confirmed the Critically Endangered status of this species, although with different criteria. This study is an example of an integrated approach for the conservation of an extremely narrow endemic plant species and may be useful for other little-known threatened species for which urgent conservation measures are needed.

The extremely rare Aquilegia paui (Ranunculaceae) was described in 1920 but was not found again until 1999, when it was discovered in the Parc Natural dels Ports in Tarragona Province, Spain. This species had been confused with the widespread A. vulgaris and consequently its taxonomic and conservation status had been misinterpreted. Based on the limited range of A. paui and the level of disturbance of its habitat we recommend that it is categorized as Endangered on the IUCN Red List. We summarize the conservation actions available for such extremely narrow endemic plant species and make appropriate recommendations for the conservation of A. paui.

We used distribution data of 121 cactus species endemic to the Chihuahuan Desert to test the effectiveness of the region’s protected area network. The analysis of species distribution using a 30′ latitude × 30′ longitude grid facilitated the identification and categorization of areas of endemism. We found a low degree of coincidence between protected areas and the areas of cactus endemism, and only 63.6% of the 121 species occur in protected areas. A complementarity analysis showed that 10 of the protected areas contain the 77 species that occur in protected areas. The four top priority areas protect 65 (84.4%) of these 77 species The 44 unprotected species are mainly micro-endemic and taxonomically distinctive taxa widely scattered in the region. The complementarity analysis applied to these species showed that all of them can be contained in a minimum of 24 grid squares, representing 32.9% of the total area occupied. Their strong spatial dispersion, along with their narrow endemism, is a major conservation challenge. We conclude that the current protected area network is insufficient to protect the rich assemblage of cacti endemic to the Chihuahuan Desert. Conservation efforts in this region should be enhanced by increasing the effectiveness of the already existing protected areas and by the creation of additional protected areas, specifically micro-reserves, to provide refuge for the unprotected species.

Threat analyses of the Boraginales were conducted and used to assess the effectiveness of Madagascar’s current and proposed protected area systems in conserving the threatened species of a group of plants widespread in Madagascar. Specimen locality data for 52 species of four families of Boraginales were analysed to provisionally assign species to IUCN Red List categories. Six species were excluded from these global analyses as they are non-native and introduced. IUCN’s criterion B, analysis of geographical range, was found to be the most reliable means of estimating threat, and predicted future decline was found to overestimate threat. Twenty-six of the 46 native species of Boraginales were found to be threatened. Sixty-five percent of these have portions of their ranges in the 2002 protected areas system. When the protected areas system was expanded in 2006 the percentage of species with some protected populations increased to 78%. More than 93% would be protected if a series of proposed priority areas for plant conservation were protected. The implications of these analyses for the conservation of plant species in Madagascar are discussed.

Terrestrial wildlife migrations, once common, are now rare because of ecosystem fragmentation and uncontrolled hunting. Botswana historically contained migratory populations of many species but habitat fragmentation, especially by fences, has decreased the number and size of many of these populations. During a study investigating herbivore movement patterns in north-west Botswana we recorded a long-distance zebra Equus burchelli antiquorum migration between the Okavango Delta and Makgadikgadi grasslands, a round-trip distance of 588 km; 55% of 11 animals collared in the south-eastern peripheral delta made this journey. This was unexpected as, between 1968 and 2004, the migration could not have followed its present course because of the bisection of the route by a veterinary cordon fence. As little evidence exists to suggest that large-scale movements by medium-sized herbivores can be restored, it is of significant interest that this migration was established to the present highly directed route within 4 years of the fence being removed. The success of wildlife corridors, currently being advocated as the best way to re-establish ecosystem connectivity, relies on animals utilizing novel areas by moving between the connected areas. Our findings suggest that medium-sized herbivores may be able to re-establish migrations relatively quickly once physical barriers have been removed and that the success of future system linkages could be increased by utilizing past migratory routes.

Scavenging raptors have been postulated to be declining at a rate far higher than predatory raptors. To test this hypothesis we reviewed the historical and present status of the seven raptor species—three scavengers (two kites and a vulture), one partial scavenger (a buzzard) and three species (osprey and two falcons) that take live prey—that breed on the Cape Verde islands. Scavenging raptors have experienced steeper declines and more local extinctions than non-scavengers in Cape Verde, with the partial scavenger midway between the two groups. Causes of scavenger decline include incidental poisoning, direct persecution and declines in the availability of carcasses and other detritus. These findings, which highlight the conservation importance of the island of Santo Antão, indicate the priority that needs to be accorded to scavengers, particularly in Europe where many insular populations are reaching unsustainable levels.

In 1994 Alan Rabinowitz decried what he regarded as lackadaisical attempts by governments, NGOs and international funding agencies to conserve the Sumatran rhinoceros Dicerorhinus sumatrensis. Sixteen years on it is timely to evaluate whether his warnings were heeded. We review the current conservation status of D. sumatrensis throughout its range and the latest threats and challenges complicating efforts to conserve this species. Recent data from governments, NGOs and researchers indicate that the global population could be as low as 216, a decline from c. 320 estimated in 1995. Based on lessons learnt and expert opinions we call on decision makers to focus on two core strategies for conservation of D. sumatrensis: (1) the translocation of wild individuals from existing small, isolated or threatened forest patches into semi-in situ captive breeding programmes, and (2) a concomitant enhancement of protection and monitoring capacities in priority areas that have established these breeding facilities or have recorded relatively high population estimates and track encounter rates. At least USD 1.2 million is required to implement these strategies annually in four priority areas: Bukit Barisan Selatan and Way Kambas National Parks on Sumatra, and Danum Valley Conservation Area and Tabin Wildlife Reserve on Sabah. Given that conservation funds are rarely secure and D. sumatrensis is still in decline we call on potential donors to help secure and augment existing capacities of organizations in these four priority areas before committing resources to elucidate the status of the species in other areas such as Gunung Leuser and Taman Negara National Parks.

There is widespread concern for many understorey and ground-dwelling bird species in the Philippines that appear intolerant of forest alteration. We present density estimates for 18 key bird species in old growth forest, advanced and early secondary growth and active cultivation within the Puerto Princesa Subterranean River National Park in Palawan. Six species were not recorded in cultivation and the abundance of these and several others increased along the successional gradient from cultivation to old growth forest. Eleven species, including five endemics and three of four threatened species, had highest density estimates in old growth forest. However, several species had high density estimates in the heavily disturbed habitats and every habitat type held highest densities of at least one of the bird species. The commonest habitat association across the bird community was a preference for areas containing large trees, indicating the importance of retention of such trees in allowing suitable ground and understorey microhabitats to persist. Old growth forests have the highest conservation value for Palawan’s endemic birds and, while some species thrive in the anthropogenic habitats that occur within the Park, the present extent of cultivation and associated successional stages within its boundaries should not be increased. We caution against extrapolation of the abundance figures from the Park to the whole island but we suggest that population sizes for the threatened species are likely to be much greater than previously thought. We urge authorities to strengthen management within the protected area network in Palawan to ensure survival of key species.

Elephants are threatened globally by habitat loss, poaching and accelerating levels of human–elephant conflict. For Elephas maximus in Cambodia, crop raiding underlies this conflict. Understanding the timing of raids and selection of crops can help design locally appropriate mitigation and management strategies. This study, using a 4-year database of events, investigated the most frequently raided crops and patterns of raids, over time and seasons and by location. Damage frequency varied significantly by crop, with rice, banana, cassava, sugar cane and papaya most frequently raided. Considering raid events per unit crop area, banana, sugar cane and pineapple were raided more than would be expected based on their availability. There were differences in both crop-raiding events and crop-damage frequencies over study years and there was a peak raiding season in October–December. Nationally, significant differences were found among provinces but not between years. Rates of damage decreased after mitigation strategies such as observation towers, deterrents and fences were implemented. We suggest further mechanisms to improve human–elephant conflict monitoring in relation to crop choice and availability.

The effect of landscape on populations is of great importance, especially given the number of species inhabiting patchy landscapes. Developments in geographical information systems are facilitating a greater application of spatial analyses to threatened species, such as the Endangered giant panda Ailuropoda melanoleuca, for which habitat patchiness and quality are key limiting factors. Of all factors that influence the suitability of habitat for the giant panda, topography is not subject to change. Here, we report a spatial and statistical analysis of the high quality topographic habitat preferred by the giant panda across its stronghold in the Qinling Mountains, China. High quality topographic habitat, as indicated by a combination of elevation, slope and aspect, covers 92,788 ha, accounting for 15% of the current range of the species. The distribution of the giant panda closely follows patterns of topography and areas with patches of high quality topographic habitat are strongly associated with areas supporting greater numbers of giant pandas. However, comparisons between our model and the existing reserve system reveals a number of inadequacies. Some of the reserves contain little high quality topographic habitat and many patches of high quality topographic habitat are unprotected. Given the importance of topography and the decisive role it plays in shaping habitat, landscapes containing high quality topographic features must be a critical consideration in the design of reserves for the giant panda. The existing system of nature reserves is heavily weighted towards judicial and administrative boundaries, to the detriment of other factors such as topography.

Habitat change has major effects on wildlife and it is important to understand how wild animals respond to changing habitats. Dashanbao National Nature Reserve, in north-east Yunnan, China, which was established for the protection of the black-necked crane Grus nigricollis, other wintering waterbirds and the upland wetland ecosystem, recently began converting farmland to grassland and woodland. With respect to this policy we studied habitat selection by black-necked cranes in the Reserve from November 2006 to April 2007. Farmland, grassland, marsh and water were used by black-necked cranes but no cranes occurred in man-made woodland. Black-necked cranes showed the least preference for grassland and no significant differences were detected in the species’ preference for the other three habitats. However, black-necked cranes exhibited different behavioural responses to the four habitats: farmland and grassland were their main foraging sites. Principle component analysis verified that a foraging-related component was the first factor determining habitat selection. Cranes used habitat close to their roosts with short grass, shallow water and less disturbance by human activity. Our results indicate that the policy of converting farmland and grassland to woodland is not beneficial for conservation of the crane. For effective conservation of the black-necked crane scientific habitat management that takes into account habitat selection by the species is required, with the retention of some farmland and restoration of wetlands.

We used transect and camera-trap surveys and DNA identification of scat samples to provide the first update since 1977 of large mammals in the montane forests of the conflict-ridden province of Nuristan in eastern Afghanistan. Nuristan contains a range of habitats from oak Quercus spp. forests to treeless alpine steppes that historically hosted populations of markhor Capra falconeri, Asiatic black bear Ursus thibetanus, grey wolf Canis lupus and common leopard Panthera pardus, among others. Surveys conducted in 2006–2009 in an area of 1,100 km2 by the Wildlife Conservation Society confirmed the presence of some of these species, and also recorded the common palm civet Paradoxurus hermaphroditus, previously unknown from Afghanistan; this extends the westernmost boundary for this species. The most commonly recorded species, as determined by direct sightings, scat identification or camera-trap photographs, were the Indian crested porcupine Hystrix indica, red fox Vulpes vulpes and a canid (grey wolf or golden jackal Canis aureus). Despite indications of significant habitat loss and unsustainable hunting, globally important species persist in the area and targeted conservation programmes are required for the protection of these species, the forests they inhabit and the surrounding communities who depend on both for their survival.

Conflicts with human interests have reappeared following recovery of large carnivores in Europe. Public acceptance is higher than historically but there is a need to identify effective, acceptable techniques to facilitate coexistence. We present a case study of predation on livestock in Slovakia. Damage, mitigation measures and public opinion were assessed using compensation records, analysis of farm conditions, questionnaire surveys, semi-structured interviews, diet analysis and on-farm trials of livestock-guarding dogs. Economic damage was inconsequential on a national scale but high locally: c. 80% of reported losses occurred at 12% of sheep flocks. Grey wolves Canis lupus were held responsible for four to six times more damage than brown bears Ursus arctos, although livestock occurred in only 2 of 78 wolf faeces during spring–autumn, when sheep and cattle were most vulnerable. Losses to Eurasian lynx Lynx lynx were negligible. Compared to other sectors of society shepherds had the most negative attitudes, particularly towards wolves, despite compensation payments. Appropriate use of livestock-guarding dogs was associated with fewer losses: median loss at trial flocks with predation was 70% lower than at control flocks. We conclude that identifying vulnerable farms and targeting them for mitigation could reduce damage, although lack of motivation and awareness are obstacles. This study shows that damage levels need not be excessive despite high predator densities in human-dominated landscapes. Conflicts were unevenly distributed, with much of the variation explained by local conditions and husbandry practices, especially preventive measures. Livestock-guarding dogs are particularly appropriate where wolves are present in proximity to unfenced pastures.

To trace the local extinction of the Eurasian otter Lutra lutra in Latium, central Italy, and examine the causes of the species’ disappearance, we reviewed and classified information from both the scientific and grey literature according to the reliability and geographical accuracy of the records. The temporal and spatial patterns of 160 records from 23 geographical subunits from 1832 to 2006 suggest that the species collapsed between 1960 and 1975; two different extinction patterns were revealed by a set of multivariate analyses. In northern Latium the species collapsed because of several independent local threats. In central and southern Latium the species collapsed because of catastrophic habitat alteration (land reclamation during the 1930s) that negatively affected the source population. After this event the species went extinct in hilly and mountainous areas, where several population sinks occurred. We presume that this latter process drove the remnant otter subpopulations to extinction in central Italy, emphasizing the role of an extinction vortex in causing the collapse of this metapopulation rather than the classical threats recognized for this species. The value of the grey literature for a posteriori historical analysis of local extinction dynamics is highlighted by this research.

The Critically Endangered black-faced lion tamarin Leontopithecus caissara has a restricted distribution consisting of small mainland and island populations each with distinct habitats in coastal south-eastern Brazil. The conservation action plan for the species recommends translocation to increase population size and promote genetic exchange among threatened isolated populations, measures that require an understanding of habitat and resource requirements. We investigated habitat selection by the black-faced lion tamarin, comparing habitats and examining frequency of use by two insular groups and two mainland groups. Using this understanding of habitat preferences we were able to refine current estimates of the carrying capacity (K) for this species. Habitats preferred by mainland groups were swamps and inundated areas and secondary forest. Submontane forest was avoided, as were hydromorphic lowland forest and urbanized areas. Island groups used mainly tall lowland forest and arboreal restinga (forest on sandy soil). The finding that L. caissara avoids montane forest sheds light on its restricted distribution to low elevation coastal plains. An estimate of K indicated c. 700 individuals, which could be increased to c. 1,500 with appropriate conservation management measures. Findings agree with the supposition that lion tamarins are typical of mature Atlantic forest, with little altitudinal variation but flexible in their use of successional stages. Future conservation management measures should account for differences in habitat use, selection and differences between island and mainland habitats.

The Near Threatened maned wolf Chrysocyon brachyurus is a South American endemic canid occurring mainly in grassland-dominated regions. We compiled and mapped recent and historical data to compare the species’ present and historical distributions and propose hypotheses for range shifts. There has been recent range expansion in eastern Brazil associated with the deforestation of the Atlantic Forest and conversion of habitat to grasslands for cattle range. The northern, north-eastern and eastern sectors of the species’ range have not yet experienced significant modifications, and the species persists in central Brazil, northern and eastern Bolivia, and south-eastern Peru. The largest range contractions have occurred at the species’ southern limits but maned wolves are still present in north-eastern, central and eastern Argentina, and there are a few records of the species' occurence from Uruguay and north-eastern and southern Rio Grande do Sul, southern Brazil. Historically the species occupied nearly all of Rio Grande do Sul, Uruguay and south to at least the 38th parallel in Argentina. The probable causes of the southern range loss are intense anthropogenic pressure combined with limiting abiotic factors such as temperature and humidity. We highlight the need to revise the view of how habitat modifications are influencing the range of C. brachyurus so as to improve and coordinate range-wide conservation strategies.
