Strengthening remaining populations

This indicator tracks the number of animal species Durrell has returned to the wild following captive breeding programmes, or moved between field sites, in order to save them from extinction.

Durrell strengthens the last remaining populations of endangered species through long-term recovery programmes. It also creates new populations where a species has died out due to a threat that has now been removed.

From Mauritius Kestrels to Mallorcan Midwife Toads to Pygmy Hogs and, most recently, Keel-scaled Boas: Durrell leads or supports projects that are working to rebuild wild populations of 23 species.

Round Island skink

Durrell’s experts and our key in-country partners have moved or released into the wild over 5,297 individual animals. That includes over 1,640 telfair’s skinks as part of efforts to restore the offshore islands of Mauritius. Closer to home, we've also released the agile frog back to Jersey, but we did this through releasing thousands of tadpoles that had been reared in captivity. On average, 4,100 tadpoles were released every year between 2006 and 2014.

Our programmes to rebuild wild populations have prevented almost certain extinctions of a number of the world’s most threatened animals and aided the recovery of many others.

The numbers above show how many individual animals have been moved or released back into the wild.
