Sergei Bereznuk - Program Director, Phoenix Fund 

Siberian (Amur) tigers are the largest and among the most critically endangered of the seven surviving tiger sub-species, and no one has done more to protect them than Sergei Bereznuk. He and his team at the Phoenix Fund, which was set up with assistance from Suwanna Gauntlett and Steve Galster, prevent poaching of tigers and leopards and work to build support for conservation throughout the Russian Far East. For his efforts, including relocating an environmentally hazardous oil pipeline away from critical leopard habitat, Sergei won the £30,000 Whitley Award for outstanding achievements in nature conservation.
