In 2005, five of the world’s leading endangered species breeding and management centers in the U.S. came together to save species in a way that’s never been done before.

Their vision became Conservation Centers for Species Survival.


The Conservation Centers for Species Survival (C2S2) cooperatively applies collective resources for the survival of threatened species with needs- large areas, natural sizes, minimal public disturbance, and research.


To provide leadership in studying and creating self-sustaining , secure populations ex situ (in human care) and in situ (in the wild) of some of the world’s most endangered species.

Since it’s inception, C2S2 has grown from 5 initial members to 16 members and we are continuing to expand. The members help protect and grow populations of C2S2’s key target species:


Nearly 50% of all animal species on earth are threatened with extinction or face decline. C2S2’s initiatives are uniquely designed to specifically address the needs of various species in peril.

Cheetah Sustainability Program

Assurance populations for endangered species

Source Population Alliance

A private/ public sector alliance creating meaningful, secured populations of herd species

Native Species Forces

Saving native species and sustaining a legacy of biodiversity in our backyards

The Members

The C2S2 Conservation Centers and Affiliates are world leaders that have recovered some of the rarest species on the planet, from the giant to the black-footed ferret to scimitar-horned oryx. The collaboration represents 100,000 acres of large, naturalist areas and decades of experience in wildlife management, recovery efforts, and reintroduction programs. These members make our entire operation possible. 

Conservation Centers

The Conservation Centers are Full Members with a land base of at least 500 acres. These institutions have a conservation history, a focus on scientific research, and are dedicated to species breeding and management, especially in naturalistic surroundings with normal group sizes and minimal public disturbance. 

Affiliate Members

The Affiliate Members are organizations (often accredited zoos, but may also be conservation-minded ranches) committed to sustainability and conservation as a priority. Each Affiliate participates in one or more of C2S2’s programs or initiatives, and a representative from the Affiliate institution serves on C2S2’s Advisory Board.

We can save species, with your help.
