The International Primate Protection League (IPPL) is a not-for-profit animal welfare organization founded in 1973 in Thailand by Shirley McGreal.
[1] IPPL's main focus is to promote the conservation and protection around the world of all non-human primates (NHP), including apes, monkeys, and lemurs.
Coordinating an international network of 15,000 members, IPPL works to curb illegal primate trafficking, intervene in abusive practices, and encourage the efforts of sanctuaries and protection groups worldwide.
[3] In countries where NHPs live, IPPL helps create and preserve national parks and sanctuaries and lobbies for bans on hunting and trapping.
Over the years, IPPL has exposed illegal animal smuggling rings and poaching operations, as well as challenged major universities, corporations, and even the U.S. military regarding their treatment and use of NHPs.
