... welcome to the intriguing, but extremely important world of amphibian conservation!
Amphibians are facing a global extinction crisis, but you may not know that we’re losing species on our very own doorstep. One example is the pool frog, which disappeared from English ponds in the 1990s.
We were asked to take part in a collaborative project with Natural England and Amphibian and Reptile Conservation to reintroduce pool frogs back into England.
Reintroducing a frog that used to live here may seem fairly straight-forward, but in fact there are many hoops to go through before you can let them hop off into the sunset. The pool frogs for this project came from Swedish populations, so one of the major risks was the introduction of a foreign disease.
Wildlife disease is one of the main areas of research here at ZSL’s Institute of Zoology, so we were charged with providing Natural England with a rigorous review of all the disease risks associated with reintroducing the frogs, and screening the individual frogs intended for release.
In 2005 permission was granted to commence the reintroduction and so on a warm summer’s day that year we drove to a secret location in the east of England to examine the first frogs for reintroduction.
Over a 3 year reintroduction period and through subsequent post-release health monitoring we carried out regular health checks on the pool frogs and I am pleased to say that they are thriving in their new home.
This spring we’re revisiting the reintroduction sites to do health checks on all the native amphibians to find out whether they’ve been impacted by their new neighbours.
Stay tuned for my next post on how to health check a common frog

Our people are our greatest asset and we realise our vision for a world where wildlife thrives through their ideas, skills and passion. An inspired, informed and empowered community of people work, study and volunteer together at ZSL.
At ZSL, a key area of our work is the employment of Nature-based Solutions – an approach which both adapt to and mitigates the impacts of climate change. These Solutions, which include habitat protection and restoration, are low-cost yet high-impact, and provide multiple benefits to people and wildlife. We ensure that biodiversity recovery is at the heart of nature-based solutions.
