Conservationists develop novel way of choosing perfect new homes for species struggling in changing climate

Posted September 6, 2013

Scientists at the Zoological Society of London (ZSL) have devised a novel method to identify suitable new homes for animals under threat from climate change.

Conservation scientists used their knowledge on species ecology to create habitat suitability maps and correctly identify sites that will remain viable in the future regardless of changing climate. However, the key for success is to understand, and account for, the link between variation in species population size, climate and how the climate may change.

Almost half of all bird and amphibian species are believed to be highly vulnerable to extinction from climate change. Species in extreme or rare habitats such as the emperor penguin in the Antarctic and American pika in the USA have already experienced drastic declines in populations due to the impact of climate change on their home.

As climate changes, many species will need to move to a different location in order to survive. For species that aren’t able to do this naturally, the only chance of survival is a helping hand through the use of translocations.

The research is published today (6 September) in the Journal of Applied Ecology.

Dr Nathalie Pettorelli, ZSL’s climate change coordinator and senior author on the paper, says: “Climate change poses a worrying threat to many animals, and relocating vulnerable species to new and more suitable habitats may be the only way to protect them. However, this is an extreme conservation action, which needs to be thoroughly justified, and requires clear guidance on where threatened populations should be moved. Our research shows how these key requirements can be met.”
