At a time when the world’s wildlife is in great peril, Conservation Centers for Species Survival (C2S2), a 501(c)(3), and its member institutions are securing populations of endangered species for assurance of survival and eventual reintroduction. Currently, eight Full and six Affiliate, national and international, members have joined in C2S2's mission to: “to provide leadership in studying and creating self-sustaining, secure populations in captivity (ex situ) and in nature (in situ) of some of the world’s most endangered species.”
