Way back last year I wrote a quick article about one of my favourite conservation organisations the Durrell Wildlife Conservation Trust. One of Durrell's major goals is to establish captive breeding colonies, ecosystem conservation / restoration and release into the wild. A lot of conservationists are still sceptical about the usefulness or effectiveness of captive breeding / release programs.
I pulled some interesting stats from the Durrell website which advertises their success with captive breeding. Some of their programs have had staggering effects on the species they work with in the wild.
For more information about how Durrell conservation projects work, have a peek at the Durrell Wildlife Conservation Trust Index which describes their ongoing process.
