One in four of our native mammals is threatened with extinction, and many others are in decline. With Britain now recognised as one of the most nature-depleted countries in the world, urgent action is needed. Our charity is trying to change this. Unlike most organisations monitoring British wildlife, we receive no central government funding for our core work. Our activities to halt the decline of threatened species, monitor their conservation status and advise on issues affecting British mammals, depends entirely on the generosity of our supporters!
