Improving the effectiveness of conservation translocations could contribute to reversing global biodiversity loss. Although evaluations of ecological factors affecting translocation outcomes are commonplace, consideration of human social factors remains rare, hindering improvements to this conservation practice. We analysed 550 translocation case s...
In 2021, the International Union for Conservation of Nature (IUCN) introduced a novel method for assessing species recovery and conservation impact: the IUCN Green Status of Species. The Green Status standardizes recovery using a metric called the Green Score, which ranges from 0% to 100%. This study focuses on one crucial step in the Green Status...
Given the scale of the current biodiversity loss, setting conservation priorities is essential to direct scarce resources to where they will be most effective. Many prioritization schemes have been described by using a wide range of criteria that vary across taxonomic groups, spatial scales, and ecological, socio-economic, and governance contexts....
Erymnochelys madagascariensis is a Critically Endangered turtle endemic to Madagascar. Anthropogenic activity has depleted the wild population by 70% in the last century, and effective conservation management is essential to ensuring its persistence. Captive breeding was implemented to augment depleted populations in the southern part of Ankarafant...
The pink pigeon (Nesoenas mayeri) is an endemic species of Mauritius that has made a remarkable recovery after a severe population bottleneck in the 1970s to early 1990s. Prior to this bottleneck, an ex situ population was established from which captive‐bred individuals were released into free‐living subpopulations to increase population size and g...
Training plays a central role in the pursuit of conservation goals, and it is vital to know if it is having the desired effect. However, evaluating the difference it makes is notoriously challenging. Here, we present a practitioner's perspective on overcoming these challenges and developing a framework for ongoing evaluation of a conservation train...
Increasing people's sense of connectedness to nature has the potential to be a powerful tool in driving pro-conservation behaviours, as well as improving physical and mental health. Multi-age cross-sectional studies have shown that nature connectedness signicantly dips after early childood before recovering in adulthood. However, the precise patter...
The use of ecological replacements (analogue species to replace extinct taxa) to restore ecosystem functioning is a promising conservation tool. However, this approach is controversial, in part due to a paucity of data on interactions between analogue species and established taxa in the ecosystem.
We conducted ecological surveys, comprehensively DN...
Robust evaluation of the impact of biodiversity conservation actions is important not only for ensuring that conservation strategies are effective and maximise return on investment, but also to identify and celebrate successful conservation strategies. This evaluation can be retrospective (comparing the current situation to a counterfactual scenari...
Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a “Green List of Species” (now the IUCN Green Status of Species). A draft Green Status framework for assessing species’ progress toward recovery, published in 2018, proposed 2 s...

Competence frameworks are widely used in many professional sectors, helping to develop capacity by defining and recognising the required skills, knowledge and personal attributes. Registers of competences have been developed within the conservation sector. A global register of competences for threatened species recovery practitioners is a register...
Aichi Target 12 of the Convention on Biological Diversity (CBD) contains the aim to ‘prevent extinctions of known threatened species’. To measure the degree to which this was achieved, we used expert elicitation to estimate the number of bird and mammal species whose extinctions were prevented by conservation action in 1993–2020 (the lifetime of th...
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, a species extinction risk assessment tool, has been guiding conservation efforts for over 5 decades. It is widely assumed to have been instrumental in preventing species from moving closer to extinction and driving recoveries. However, the impact of the IUCN R...
Comparative assessment of the relative information content of different independent spatial data types is necessary to evaluate whether they provide congruent biogeographic signals for predicting species ranges. Opportunistic occurrence records and systematically collected survey data are available from the Dominican Republic for Hispaniola’s survi...
Aichi Target 12 of the Convention on Biological Diversity (CBD) aims to 'prevent extinctions of known threatened species'. To measure its success, we used a Delphi expert elicitation method to estimate the number of bird and mammal species whose extinctions were prevented by conservation action in 1993 - 2020 (the lifetime of the CBD) and 2010 - 20...
The Critically Endangered mountain chicken (Leptodactylus fallax), found on the Caribbean islands of Dominica and Montserrat, underwent one of the fastest declines observed in any vertebrate species due to the chytrid fungus Batrachochytrium dendrobatidis. A remnant population of c.130 individuals survives on Dominica but the Montserrat population...
The climate emergency and crisis of biodiversity loss show that the human–nature relationship is failing. This paper introduces the psychological construct of nature connectedness as a measurable target for improving the human–nature relationship, and therefore helping tackle the warming climate and loss of wildlife. The ‘pathways to nature connect...
Vulnerability to habitat fragmentation
Habitat fragmentation caused by human activities has consequences for the distribution and movement of organisms. Betts et al. present a global analysis of how exposure to habitat fragmentation affects the composition of ecological communities (see the Perspective by Hargreaves). In a dataset consisting of 448...
Historical data are a valuable resource for addressing present-day conservation issues, for example by informing the establishment of appropriate recovery targets. However, while the recovery of threatened species is the end goal of many conservation programmes, data made available through the efforts of palaeoecologists and historical ecologists a...
Emerging infectious diseases are an increasingly important threat to wildlife conservation, with amphibian chytridiomycosis, caused by Batrachochytrium dendrobatidis, the disease most commonly associated with species declines and extinctions. However, some amphibians can be infected with B. dendrobatidis in the absence of disease and can act as res...

Understanding genetic structure and diversity underpins the management of isolated populations. Small populations confined to islands may require effective genetic management for population persistence due to inbreeding and reduced genetic diversity. Endemic to the offshore islands of mainland Mauritius, the Bojer’s skink (Gongylomorphus bojerii) h...
Conservation decision-making for threatened species in human-modified landscapes requires detailed knowledge about spatial ecology, but robust data derived from tracking individual animals are often unavailable, with management decisions potentially based on unreliable anecdotal data. Existing data are limited for Hispaniola's two threatened non-vo...
The Hispaniolan solenodon, Solenodon paradoxus, and Hispaniolan hutia, Plagiodontia aedium, are the Dominican Republic’s only surviving endemic non-volant land mammals, and are high priorities for conservation. The country has an extensive protected area (PA) network designed to maintain habitats and benefit biodiversity, but which faces significan...
The illegal wildlife trade is driving declines in populations of a number of large, charismatic animal species but also many lesser known and restricted-range species, some of which are now facing extinction as a result. The ploughshare tortoise Astrochelys yniphora , endemic to the Baly Bay National Park of north-western Madagascar, is affected by...
The penultimate volume of the Handbook of Mammals of the World covers all of the remaining orders (Cingulata, Pilosa, Afrosoricida, Macroscelidea, Scandentia, Dermoptera, and Eulipotyphla), other than bats (Chiroptera). From armadillos, sloths, and anteaters to shrews and moles, Volume 8 includes a wide variety of interesting small or medium-sized...

Stopping declines in biodiversity is critically important, but it is only a first step toward achieving more ambitious conservation goals. The absence of an objective and practical definition of species recovery that is applicable across taxonomic groups leads to inconsistent targets in recovery plans and frustrates reporting and maximization of co...
There is a major gap in funding required for conservation, especially in low income countries. Given the significant contribution of taxpayers in industrialized countries to funding conservation overseas, and donations from membership organisation, understanding the preferences of ordinary people in a high income country for different attributes of...

Rodents include species that have colonized almost every available habitat on earth, and others that have adapted to human beings and followed them as they also spread across the globe. Volume 7 completes the order Rodentia—which represents arguably the most important order of mammals, both in terms of number of species, and in geographic distribut...
Reflecting a global trend, freshwater wetlands in Madagascar have received little conservation or research attention. Madagascar is a global conservation priority due to its high level of species endemism but most work has focused on protecting forests. For the first time, we investigated the state of wetlands across the country to determine the ef...

The insular Caribbean is among the few oceanic-type island systems colonized by non-volant land mammals. This region also has experienced the world’s highest level of historical mammal extinctions, with at least 29 species lost since AD 1500. Representatives of only 2 land-mammal families (Capromyidae and Solenodontidae) now survive, in Cuba, Hispa...
The global amphibian crisis and current un-mitigatable threats make ex situ programmes a crucial complementary action for the conservation of many amphibians. Zoos and aquariums are some of the most important and influential groups of institutions to undertake this yet the proportion of globally threatened amphibians in zoos is just 23.9% compared...

The Livingstone's fruit bat Pteropus livingstonii is endemic to the small islands of Anjouan and Mohéli in the Comoros archipelago, Indian Ocean. The species is under threat from anthropogenic pressure on the little that remains of its forest habitat, now restricted to the islands’ upper elevations and steepest slopes. We report the results of the...
Amphibian chytridiomycosis has caused precipitous declines in hundreds of species worldwide. By tracking mountain chicken (Leptodactylus fallax) populations before, during and after the emergence of chytridiomycosis, we quantified the real-time species level impacts of this disease. We report a range-wide species decline amongst the fastest ever re...
The outcomes of species recovery programmes have been mixed, with high-profile population recoveries contrasting with species-level extinctions. Although each conservation intervention faces its own challenges, it is imperative to assess whether such lessons have wider general applicability. To contribute towards evidence-based improvement of futur...
Understanding how fishers make decisions is important for improving management of fisheries. There is debate about the extent to which small-scale fishers follow an ideal free distribution (IFD) – distributing their fishing effort efficiently according to resource availability rather than being influenced by social factors or personal preference. U...
Proportions of catch and effort observed across all gear types at fishing locations in Lake Alaotra, calculated for all fishers who also participated in background interviews (n = 788 catch interviews with 151 individual fishers). The pattern shown is similar to Fig. 2a and so justifying the use of the background interview dataset for all future an...

To determine the evolutionary history, relationships and distinctiveness of allopatric populations of Hispaniolan solenodon ( Solenodon paradoxus ), a highly threatened Caribbean ‘relict’ mammal, to understand spatio‐temporal patterns of gene flow and the distribution of diversity across complex large island landscapes and inform spatial conser...
The outcomes of species recovery programs have been mixed; high-profile population recoveries contrast with species-level extinctions. Each conservation intervention has its own challenges, but to inform more effective management it is imperative to assess whether correlates of wider recovery program success or failure can be identified. To contrib...
Abstract Continued uncertainty persists over the taxonomic status of many threatened Caribbean mammal populations. Recent molecular analysis has identified three genetically isolated allopatric hutia populations on Hispaniola that diverged during the Middle Pleistocene, with observed levels of sequence divergence interpreted as representing subspec...
Global amphibian declines are one of the biggest challenges currently facing the conservation community, and captive breeding is one way to address this crisis. Using information from the International Species Information System zoo network, we examined trends in global zoo amphibian holdings across species, zoo region, and species geographical reg...
Artisanal fisheries are a key source of food and income for millions of people, but if poorly managed, fishing can have declining returns as well as impacts on biodiversity. Management interventions such as spatial and temporal closures can improve fishery sustainability and reduce environmental degradation, but may carry substantial short-term cos...
Although birds are among the best studied taxa, many of the globally threatened species lack the information required to fully assess their conservation status and needs. One such species is the Anjouan Scops Owl Otus capnodes which was presumed extinct until its rediscovery to science in 1992. Based on the limited extent and decline of the moist f...
Experimental evidence of the interactions among mammalian predators that eat or compete with one another is rare, due to the ethical and logistical challenges of managing wild populations in a controlled and replicated way. Here, we report on the opportunistic use of a replicated and controlled culling experiment (the Randomised Badger Culling Tria...
Habitat fragmentation studies have produced complex results that are challenging to synthesize. Inconsistencies among studies may result from variation in the choice of landscape metrics and response variables, which is often compounded by a lack of key statistical or methodological information. Collating primary datasets on biodiversity responses...
The rapid global growth of conservation schemes designed to incentivize local communities to conserve natural resources has placed new importance on biological monitoring to assess whether agreements and targets linked to payments are being met. To evaluate competence in natural resource monitoring, we compared data on status and trends collected i...
Madagascar still retains extensive wetlands important for fishing, hunting and
agriculture. They also support a high proportion of the island’s globally threatened
endemic birds. However, as a result of widespread modification through human
activity, wetlands are under severe pressure across the island, resulting in the decline
of many waterbird sp...
Mammals are a disparate group, but large mammals in particular have similar conservation needs. They tend to need large areas and to be relatively slow growing, making them less resilient. They are more likely to be killed by humans for their meat, trophies, or because they are a danger or a nuisance. Conservation efforts for mammals particularly f...
We describe the conservation history of the Angonoka, or Ploughshare Tortoise (Astrochelys yniphora), that has led to its current status as the world’s rarest tortoise. Because of the scale of poaching that threatens this tortoise and the fact that individuals are illegally sold around the world, conservation of this species is a truly global probl...
Waterbirds are a globally-distributed, species-rich group of birds that are critically dependent upon wetland habitats. They can be used as ecosystem sentinels for wetlands, which as well as providing ecosystem services and functions essential to humans, are important habitats for a wide range of plant and animal taxa. Here we carry out the first g...
Understanding the dynamics of the Late Quaternary Caribbean mammal extinction event is complicated by continuing
uncertainty over the taxonomic status of many species. Hispaniola is one of the few Caribbean islands to retain native
non-volant mammals; however, there has been little consensus over past or present levels of diversity in Hispaniolan h...
Tourism development is one of the main contemporary drivers of habitat loss and fragmentation within the Caribbean Islands biodiversity hotspot. In Saint Lucia, construction of a hotel and golf course within coastal dry forest is directly threatening the largest known subpopulation of the Endangered White-breasted Thrasher Ramphocinclus brachyurus....
The Caribbean Islands Biodiversity Hotspot is exceptionally important for global biodiversity conservation due to high levels of species endemism and threat. A total of 755 Caribbean plant and vertebrate species are considered globally threatened, making it one of the top Biodiversity Hotspots in terms of threat levels. In 2009, Key Biodiversity Ar...
Reduced Emissions from Deforestation and Forest Degradation in Developing Countries (REDD+) is a policy mechanism now agreed under the United Nations Framework Convention on Climate Change (UNFCCC). It aims to reduce carbon dioxide emissions from developing countries through the sustainable management of forests, while providing co-benefits of biod...
A rapidly developing tourism industry, concentrated in coastal regions, is suspected to seriously impact upon biodiversity in the global conservation priority of the insular Caribbean. In St Lucia, construction of tourism infrastructure in the coastal dry forest threatens the Endangered White-breasted Thrasher Ramphocinclus brachyurus. Long-term pr...
The Alaotran gentle lemur Hapalemur alaotrensis is a Critically Endangered lemur, which exclusively inhabits the marshes around Lac Alaotra in northeast Madagascar. In the past decades the population of H. alaotrensis has experienced a dramatic decline due to poaching, habitat destruction and degradation. Surveys have been carried out periodically...

1. Statistical modelling of habitat suitability is an important tool for planning conservation interventions, particularly for areas where species distribution data are expensive or hard to collect. Sometimes however the predictor variables typically used in habitat suitability modelling are themselves difficult to obtain or not meaningful at the g...
Although monitoring is an essential tool for biodiversity conservation, monitoring programmes are often poorly designed and thus unlikely to produce results that are meaningful for management. Monitoring is especially challenging when dealing with rare and elusive species in areas where conservation resources are particularly limited. In such cases...
Habitat destruction and predation by invasive alien species has led to the disappearance of several island populations of Darwin's finches but to date none of the 13 recognized species have gone extinct. However, driven by rapid economic growth in the Galápagos, the effects of introduced species have accelerated and severely threatened these iconic...
The Critically Endangered Montserrat galliwasp is found only on Montserrat and, even here, is known only
from a tiny area – Woodlands Estate – of a few hectares. With funding from the Overseas Territories Environment
Programme (OTEP), this SAP was developed at a participatory workshop in Montserrat, as a fiveyear
plan of action to ensure the future...
The Endangered Madagascar giant jumping rat, Hypogeomys antimena, has suffered a major decline in distribution and is now restricted to two seemingly unconnected sub-populations in the largest remaining fragment of deciduous, seasonally dry forest in Menabe, western Madagascar. In a previous study a rapid decrease in numbers of H. antimena was obse...
The Madagascar flat-tailed tortoise Pyxis planicauda is threatened with extinction through loss of its deciduous, dry forest habitat and illegal collection for the pet trade. Little is known of the population status of this species as no systematic survey across its range has previously been conducted. Surveying P. planicauda is problematic as it h...
The amphibian fauna of the Central Menabe region in Western Madagascar is important in respect to their extraordinary adaptations to the dry forest habitat. This habitat is highly threatened. Until 1990, the dry forest in the west of the island was thought to have been reduced to only 3% of its original extent. New analyses show that this deforesta...
Changes in the relative abundance of sympatric carnivores can have far-reaching ecological consequences, including the precipitation of trophic cascades and species declines. While such observations are compelling, experimental evaluations of interactions among carnivores remain scarce and are both logistically and ethically challenging. Carnivores...
