#re-edenization

"After the research showed the extinct pool frog to be a native British species, the ARC and its collaborators went to work. They started by restoring its habitat and implementing rigorous biosecurity protocols so they could safely fly a group of frogs across the North Sea to re-establish a native population. They then captured pool frogs, tadpoles and spawn in Sweden, where its closest relatives still live, and brought them to a secret location in Norfolk in 2005, hoping to re-establish a small colony there. Tadpoles produced by that secret population were relocated and released in Thompson Common in 2015. Thompson Common is perfect for these frogs: it’s filled with small glacial relict ponds, known as ‘pingos’ (from an Inuit word for a conical hill). Pingo ponds hold fresh water throughout the year and thus, are an ideal location for sun-loving pool frogs."
