New study offers hope that conservation can help nature adapt to climate change
05 Apr 2022 | No. 2022-17
A new study, reviewing a suite of published scientific research, provides evidence that conservation action can help species adapt to a changing climate. This offers hope that conservation can play a key role in safeguarding species and their populations.
Climate change is increasingly affecting natural ecosystems around the world, fuelling growing concern about its potential to drive many species towards extinction. Whilst limiting greenhouse gas emissions will reduce the magnitude of future climate change, there is also an urgent need to understand whether effective conservation action can also help vulnerable species to cope with climate change (termed ‘adaptation’).
A newly published study, led by the British Trust for Ornithology (BTO), addresses this gap by reviewing the conservation literature, including that collated by Conservation Evidence, to identify studies which test the effectiveness of conservation actions on species’ populations also affected by climatic factors. Out of the 77 studies identified (from the thousands examined), 62 (81%) reported at least one beneficial response to the conservation actions taken, highlighting growing evidence that conservation actions can indeed help vulnerable species cope with climate change. Successful measures included restoring native vegetation to reduce the negative impacts of drought, maintaining an effective protected area network to help species shift their distribution in response to climate change, and actively managing vulnerable populations so they can cope with climatic extremes such as flooding or high temperatures.
Conservation interventions targeted at the recovery of individual species were estimated to be the most effective, demonstrating benefit on three quarters of occasions. Although wider conservation interventions, such as the establishment of protected areas or habitat management, were estimated to be less beneficial for individual species, the fact that such measures are likely to influence a larger number of species than more targeted actions means that they are also worthwhile in a changing climate. Within the UK, for example, the network of protected areas has facilitated the expansion of the Dartford Warbler, a species of conservation concern, while more widely across Europe such networks have been important for the conservation of migratory waterbirds affected by climate change.
Dr Katharine Bowgen of the British Trust for Ornithology and lead author of the report said “It was really encouraging to see the number and range of conservation interventions that were identified as helping species cope with a changing climate. Our study provides more evidence that conservation action can help nature adapt to climate change.”
Professor James Pearce-Higgins, British Trust for Ornithology’s Director of Science who oversaw this research said “This study provides much needed evidence to show how conservation organisations should respond to climate change and to support investment in climate change adaptation. Targeted adaptation may help the most vulnerable species persist in a changing climate, whilst promoting effective protected area networks and improving the condition of degraded habitats is likely to benefit large numbers of species."
Dr Wendy Foden, co-author of this study and Chair of the IUCN SSC Climate Change Specialist Group said “This study should spur conservation organisations to action. However, it is important that they monitor the effectiveness of their actions so we can build on this study and better understand what works, where and when. This is particularly the case in the tropics and Southern Hemisphere where far more studies are needed.”
Co-author Dr Georgina Magin from Fauna & Flora International said "Over recent years the complex inter-relationships between climate change and biodiversity loss have become increasingly evident; the impact of a changing climate on biodiversity also has wider implications for the broader services that nature provides. This study highlights the significant opportunity for targeted measures to support the adaptation of individual species in the face of climate change, an important finding for the planning of conservation responses in the context of future climate scenarios.”

BTO is the UK's leading bird research charity. A growing membership and up to 60,000 volunteer birdwatchers contribute to BTO's surveys, collecting information that underpins conservation action in the UK. BTO maintains a staff of 100 at its offices in Thetford, Stirling, Bangor (Wales) and Belfast (Northern Ireland), who analyse and publicise the results of surveys and projects. BTO's work is funded by BTO supporters, government, trusts, industry and conservation organisations. www.bto.org
Summer migrants stay for longer as the UK climate warms
Data collected by volunteer citizen scientists have been used to show how the timing of bird migration to and from the UK has changed since the 1960s.
