The institutional arrangements governing forests will be a critical factor in reducing emissions from deforestation and forest degradation (REDD) as part of the global effort to mitigate climate change. A growing body of empirical research demonstrates how local forest governance can be as, if not more, effective than centralized state-based regimes. Local forest governance can secure improvements in multiple forest outcomes such as biomass and carbon storage and livelihoods contributions for the poor, and it can do so at lower cost than is possible through centralized governance. Many national governments have implicitly recognized these findings in their pursuit of decentralized forest governance and in strengthening local rights and capacities to use and manage forests. However, such reforms are often politically resisted, particularly where the value of forest resources is high and central government bodies are able to capture the majority of benefits. Ongoing negotiations related to the design and delivery of REDD policy and practice must take into account both the importance of local forest governance arrangements and the political–economic barriers to devolving secure rights over forests to local communities. These political dimensions of forest tenure and policy create a paradox for REDD: increasing the value of forest resources through global carbon markets without attending to local governance and rights will create political incentives towards centralized governance, which could lead to greater forest loss and lower forest-related benefits for the poor.

The proposed mechanism for Reducing Emissions from Deforestation and Degradation (REDD+) offers significant potential for conserving forests to reduce negative impacts of climate change. Tanzania is one of nine pilot countries for the United Nations REDD Programme, receives significant funding from the Norwegian, Finnish and German governments and is a participant in the World Bank’s Forest Carbon Partnership Facility. In combination, these interventions aim to mitigate greenhouse gas emissions, provide an income to rural communities and conserve biodiversity. The establishment of the UN-REDD Programme in Tanzania illustrates real-world challenges in a developing country. These include currently inadequate baseline forestry data sets (needed to calculate reference emission levels), inadequate government capacity and insufficient experience of implementing REDD+-type measures at operational levels. Additionally, for REDD+ to succeed, current users of forest resources must adopt new practices, including the equitable sharing of benefits that accrue from REDD+ implementation. These challenges are being addressed by combined donor support to implement a national forest inventory, remote sensing of forest cover, enhanced capacity for measuring, reporting and verification, and pilot projects to test REDD+ implementation linked to the existing Participatory Forest Management Programme. Our conclusion is that even in a country with considerable donor support, progressive forest policies, laws and regulations, an extensive network of managed forests and increasingly developed locally-based forest management approaches, implementing REDD+ presents many challenges. These are being met by coordinated, genuine partnerships between government, non-government and community-based agencies.

Forest loss and degradation in the tropics contribute 6–17% of all greenhouse gas emissions. Protected areas cover 217.2 million ha (19.6%) of the world’s humid tropical forests and contain c. 70.3 petagrams of carbon (Pg C) in biomass and soil to 1 m depth. Between 2000 and 2005, we estimate that 1.75 million ha of forest were lost from protected areas in humid tropical forests, causing the emission of 0.25–0.33 Pg C. Protected areas lost about half as much carbon as the same area of unprotected forest. We estimate that the reduction of these carbon emissions from ongoing deforestation in protected sites in humid tropical forests could be valued at USD 6,200–7,400 million depending on the land use after clearance. This is > 1.5 times the estimated spending on protected area management in these regions. Improving management of protected areas to retain forest cover better may be an important, although certainly not sufficient, component of an overall strategy for reducing emissions from deforestation and forest degradation (REDD).

We examined the literature on animal reintroductions to assess the challenges facing individual conservation practitioners who wish to access, synthesize and interpret available evidence to inform their decision making. We undertook an extensive search in eight electronic literature databases, using seven different keyword combinations, and added the content of four bibliographies on reintroductions. We found 3,826 potentially relevant publications totalling at least 29,290 pages of text. Taxonomic bias is apparent in the distribution of general and conservation scientific literature and in reintroduction programmes. We examined whether the literature on reintroductions is biased in a similar way. Comparing the distribution of reintroduction publications to numbers of species, reintroduction programmes and the general conservation literature, there is a marked taxonomic bias favouring vertebrates, especially birds and mammals. The bias in relation to reintroduction programmes is surprising and indicates that managers working with invertebrates and amphibians are less willing and/or less able to publish their results than those working with mammals and birds. The reasons for this are unclear. The growth of the cumulative body of literature can be depicted by a sigmoid curve. Almost 40% of the items were scientific journal articles distributed across 335 journals. The large, ever-growing and dispersed evidence base results in an increased need for reviews, which must be systematic to minimize bias.

We conducted surveys in the Trans-Himalayan Tso Lhamo plateau in Sikkim, India, to ascertain the status and distribution of some of India’s last surviving populations of wild ungulates (numbers in brackets are estimates for Sikkim): Tibetan argali Ovis ammon hodgsoni (c. 177 individuals), Tibetan gazelle Procapra picticaudata (c. 77), and kiang Equus kiang polyodon (c. 18). Topography appears to have an important influence on ungulate distribution, and populations of these species are aggregated in a small region along the northern boundary of the plateau. Persistence of the wild ungulates in this area can be attributed to the non-hunting tradition of local residents and to the seasonal absence of livestock (yak Bos grunniens and domestic sheep Ovis aries) and grazing. Nonetheless, wild ungulates remain vulnerable because of their small populations and anthropogenic pressure on their habitats. We recommend that conservation be prioritized in important wildlife habitats through partnerships with local communities.

In this study I estimate population densities and biomass of the major prey species of tiger Panthera tigris, leopard Panthera pardus and dhole Cuon alpinus in Bhutan’s temperate ecosystem and recommend measures for reducing crop damage whilst simultaneously protecting ungulate populations. Thirty-two transects totalling 849 km were walked to estimate densities and biomass of ungulates and primates in Bhutan’s Jigme Singye Wangchuck National Park during 2005–2006. Adequate detections (> 40 sightings) for analysis using Distance were obtained for wild pig Sus scrofa (n = 54), muntjac Munticus muntjac (n = 102) and sambar Cervus unicolor (n = 48). Because of similarity in morphology and habitat use, density of serow Capricornis sumatraensis was estimated using the detection probability for sambar. Detections for langur Trachypithecus geei and macaque Macca mulatta were combined (n = 39) to estimate primate density. Mean estimated densities were 3.68 wild pig, 2.17 muntjac, 1.19 sambar, 2.37 primates and 0.36 serow km-2. The three primary prey species of large predators, wild pig, sambar and muntjac, provided a biomass of 379 kg km-2, which could support up to 1.2 tigers per 100 km2. However, the presence of other sympatric carnivores competing for prey in the same area suggests that the actual number of tigers that could be supported is lower. Livestock (density, 6.0 km-2; biomass, 615 kg km-2) apparently supplement prey availability. Ungulate density in the study area is generally low compared to other areas in the Indian sub-continent, and this may be due to conflicts with farmers, excessive grazing of livestock in the forest and the rugged terrain.

We evaluated the status of tigers Panthera tigris and their prey in Panna Tiger Reserve using occupancy surveys, camera-trap mark-recapture population estimation, and distance sampling along foot transects, in 2006. Forest Range tiger occupancy in the Panna landscape (3,500 km2) estimated by 1,077 surveys of 5 km each was 29% ± SE 1. Within occupied Ranges of the Reserve a mean of 68% ± SE 7 of forest Beats had tiger signs. A total of 800 camera-trap nights yielded 24 captures of seven individual adult tigers within an effective trap area of 185.0 ± SE 15.8 km-2. The best model incorporating individual heterogeneity (Mh) estimated the tiger population to be 9 ± SE 2. Tiger density was 4.9 ± SE 1.5 per 100 km2 and was lower than that reported in 2002 (6.49 tigers per 100 km2). Both occupancy and density indicated a decline of the tiger population in the Reserve. Mean ungulate density was 42.4 ± SE 8.4 km-2 and comparable to other tiger reserves. Since our survey in 2006 tiger status in Panna has deteriorated further because of poaching. Panna was occupied by dacoits in late 2006 and anti-insurgent activities caused further disturbances. In late 2008 there was a single male tiger left in Panna but he has not been seen since January 2009. The Madhya Pradesh Forest department has reintroduced three tigers to Panna from neighbouring tiger reserves. Panna, along with Sariska Tiger Reserve, exemplifies the vulnerability of small, isolated tiger populations to local extinctions caused by poaching, even in areas with suitable habitat and sufficient prey.

Two issues of central importance to conservation are developing an improved understanding of the relative roles of state protected areas and local institutions and developing effective strategies for creating community-based incentives for conservation. We provide a case study of northern Tanzania’s Maasai Steppe to explore these issues in the context of a savannah ecosystem where wildlife is mobile and depends extensively on community lands for seasonal habitats. We compare the impacts and outcomes of four approaches to developing local incentives for wildlife conservation on community lands: protected area benefit-sharing, trophy hunting donations, village–private tourism concession contracts, and a direct payment scheme for habitat conservation. Tourism and direct payment concession areas have resulted in large areas of community land being protected for wildlife by villages as a result of the conditional and contractual nature of these ventures. By contrast, other approaches that provide economic benefits to communities but are not conditional on defined conservation actions at the local level demonstrate little impact on wildlife conservation on community lands. In spatially extensive ecosystems where protected areas cover limited areas and wildlife relies heavily on community and private lands, strategies based on maximizing the direct income of communities from wildlife are fundamental to the sustainability of such systems.

The aim of this study was to determine the minimum conservation area needed to conserve vegetation types and their landscape and to apply it to an area in KwaZulu-Natal, South Africa, which is within the Maputaland Centre of Plant Endemism and part of the Maputaland–Pondoland–Albany biodiversity hotspot. Outside conservation areas this Centre of Plant Endemism is under threat from human utilization. We used a method initially designed to determine minimum conservation areas for rare plant species, which we adapted from its original country and context, to determine minimum conservation areas for landscape species in Maputaland’s little-documented environment. The minimum area required for conservation was established for the Sand Forest and Woodland vegetation types in the region. We found that sufficient habitat is presently conserved to preserve the Sand Forest but not the Woodlands. The method holds promise to provide answers to critical conservation issues in lesser-known environments and, although relatively difficult to establish for the first time, is an efficient and easy to use tool that can be refined once more knowledge becomes available.

We assessed the consumption and hunting of wild animals by people in urban areas of western Madagascar using structured questionnaires in households and direct observations. Six wild mammal and five wild bird species were reported, or observed, to be sources of bushmeat although fish and domestic animals were the preferred and cheapest sources of animal protein. Bushmeat accounted for 10% of the meat consumed the day before our questionnaires were completed. Common tenrec Tenrec ecaudatus and bush pig Potamochoerus larvatus were the preferred wild meat and the former was also the most expensive type of meat. Taboos and strong dislikes limited the consumption of domestic pigs, bush pigs, goats, lemurs and fruit bats. Game species were hunted according to their availability, which coincided with the legal hunting season for fruit bats but only partly so for the other game species. Illegal hunting of Verreauxi’s sifaka Propithecus verreauxi is cause for concern and assessments of primate consumption may have been underestimated because of reluctance of interviewees to admit illegal activities.

Flying foxes of the genus Pteropus are predominantly island taxa, with high levels of endemism, and face high risks of extinction. Their ecological and economic importance in island ecosystems has been widely recognized. Here we investigate the population size and conservation status of the Vulnerable Pteropus voeltzkowi, endemic to the western Indian Ocean island of Pemba, Tanzania. Direct counts and patch counts were used to determine abundance of flying foxes at roost sites, supplemented with evening dispersal counts, which were conducted to test accuracy of counting techniques under varying conditions of visibility. We estimate that the population size is now a minimum of 18,200–22,100, thus validating reports of annual increases by in-country monitoring teams since the last documented population survey of 4,600–5,500 bats in 1995. Taking into account differences in the counting methodologies for roosting bats we estimate that the population size could be as high as 35,600 individuals. We identified 44 occupied roosting sites, with just four of these supporting up to 87% of the population. Roost disturbance represents a continuing threat to this species and was found to influence roost occupancy and colony size. The implications of the population increase for the local human community are discussed and recommendations provided for continued monitoring and future management of this species on Pemba Island.

Identifying threats to declining species and prescribing ways of preventing their extinction are basic challenges for biodiversity conservation. We analysed the causes underlying the loss of territories of the Endangered Egyptian vulture Neophron percnopterus in a key population at the north-western edge of its distribution in Europe by developing multi-scale models that combined factors from nest site to landscape. We used generalized linear models and an information-theoretic approach to identify the optimal combination of scales and resolutions that could explain territorial abandonment. Those models combining nest-site and landscape scales considerably improved prediction ability compared to those considering only one scale. The best combined model had a high predictive ability (96.9% of correctly classified cases). Small cliffs at high altitudes in rugged areas with declining livestock (especially of sheep and goats) increased the likelihood of territory abandonment. Our findings highlight the importance of developing region-specific multi-scale models to determine reliably the factors driving territory loss and of designing effective conservation strategies accordingly. Conservation measures for the studied population should be developed at two spatial scales. At the smaller scale it is necessary to closely control nest sites to avoid direct disturbances. At a larger scale it is essential to implement policies that can support traditional pastoralism.

The Egyptian vulture Neophron percnopterus is categorized as Endangered on the IUCN Red List, as well as on the European and Spanish Red Lists. Spain is home to the most important breeding population of Egyptian vultures in Europe but this population has differing trends at a regional scale. We present data for the Egyptian vulture population in the Cantabrian Mountains, north-west Spain, during the last 3 decades and assess the main threats to the species there. The Egyptian vulture population in the Cantabrian Mountains was estimated to be 175 breeding pairs in 2008, which comprised 13–14% of the Spanish population. This population has been stable, or increasing slightly, since 2000. During 2000–2008 4.3% of the Cantabrian Egyptian vulture population was affected by the use of illegal poison. During the same period the number of sheep and goats reared (which contributes to the maintenance of Egyptian vulture territories) was reduced by 27.4%, which could lead to food shortages for the vultures in the near future. Currently 32 breeding pairs (18.3% of the population) have wind turbines within their foraging areas, with an average of 59 wind turbines per territory (range 1–176). During the next few years this number will increase to 110 turbines per territory within 69 vulture territories (39.4% of the population). Nearly a third (32.6%) of breeding territories are located outside protected areas. Better coordination between administrative areas is needed to guarantee the conservation of the Cantabrian Mountains population of Egyptian vultures through effective surveillance and protection in the numerous existing protected areas.

Estimations of the population sizes of threatened species are fundamental for conservation. The current estimate of the population of the Andean condor Vultur gryphus is based on limited local counts. Simultaneous censuses of 10 condor communal roosts were therefore conducted during 2006–2008 in north-west Patagonia, Argentina, to obtain a minimum population number, to estimate the size of the local population, and to describe use of the roosts by season and age classes. I fitted the data to two asymptotic models to calculate the population of condors as a function of the number of communal roosts surveyed. In an area of c. 6,300 km2 I obtained a minimum population size of 246 individuals by direct observation, and a population estimate of 296 condors (range 260–332) by applying the models. This population, the largest known of this species, comprises 68.5% adults and 31.5% immatures. Condors had large aggregations in some communal roosts and used the area seasonally, increasing in numbers from autumn to spring and decreasing in summer. Long-term monitoring of communal roosts across the Andean condor’s range is essential for the monitoring of this rare and vulnerable species.
