Rebuilding wild populations How many species has Durrell helped restore through rebuilding wild 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.

Durrell’s experts have moved or released into the wild over 4,100 individual animals. That includes over 1,100 Telfair’s Skinks as part of efforts to restore the offshore islands of Mauritius which, in turn, has led to the recovery of its natural predator, the Keel-scaled Boa. 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 below show how many individual animals have been moved or released back into the wild.
