One of the sites in the Adopt a Home for Wildlife initiative of UKOTCF & Montserrat National Trust is being used also as an experimental location for reintroduction of the Critically Endangered 'mountain chicken' frog - which occurs only on Montserrat and Dominica. Like many amphibians around the world, the survival of this species is threatened by an introduced fungus. Our 9-minute video describes the testing of the experimental manipulation of conditions to help the frogs overcome this. The latest news since this video was made is that, in July 2019, the first batch of frogs themselves have arrived so that we can see how the experiment works.
