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...
Article
Full-text available
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...
Article
Full-text available
1. 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. 2. We conducted ecological surveys, comprehensiv...
Article
Full-text available
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...

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...
Conference Paper
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...
Article
Full-text available
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...
Article
Habitat loss is the primary driver of biodiversity decline worldwide, but the effects of fragmentation (the spatial arrangement of remaining habitat) are debated. We tested the hypothesis that forest fragmentation sensitivity-affected by avoidance of habitat edges-should be driven by historical exposure to, and therefore species' evolutionary respo...
Article
Full-text available
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...
