Primate Specialist Group
The Primate Specialist Group is a network of scientists and conservationists who stand against the tide of extinction which threatens humanity’s closest kin.

Active throughout the tropical world, working in dozens of nations in Africa, Asia and Latin America, the PSG promotes research on the ecology and conservation of hundreds of primate species — monkeys, apes, lemurs and their many nocturnal relatives.
Now more than ever before primates need our intervention: one in every four primate species is threatened or endangered, and the double hammer of overhunting and forest devastation has brought some species to within a few dozen heads of final extinction.

The PSG works on behalf of these and all other primates by supporting field research, conservation measures and educational programs in those regions where primates still occur.
