Species Survival Plan®

There are over 107 species survival plans covering 161 species administered by the Association of Zoos and Aquariums (AZA).

Species range from lions and rhinos to toads and toucans. You can find out more about SSPs at

captive population
of over 360 gorillas
in North America.

The Gorilla SSP®


The Gorilla Species Survival Plan (SSP) serves 51 zoos across the United States to help guide the management of the gorilla population. Although our primary role is in population management, we are ultimately interested in the health and well-being of ALL gorillas, including those living outside accredited zoos and in the wild. The Gorilla SSP is administered under the Ape Taxon Advisory Group (TAG).
The primary goals of an SSP are to treat an entire population of animals as a single unit
and promote cooperation among holding institutions to ensure the long term survival of the species in captivity. A minority of SSP populations support wild populations through reintroduction programs, but the majority of SSP programs exist solely to create a sustainable captive population to advance the mission of zoos for many years to come. Holistic SSP programs extend beyond captive management to encompass scientific research, conservation, and education programs that support populations in zoos and in the wild.

On 12 September 2007, Western gorillas - the only species seen in zoos - were re-classified from "Endangered" to "Critically Endangered" by The World Conservation Union (IUCN). Only a decade ago scientists estimated there were more than 100,000 Western gorillas in Africa, but threats from the bushmeat crisis (illegal, unsustainable hunting of
wild animals) and Ebola virus have wiped out so many gorillas that current estimates
are closer to 30,000. Many of the gorillas killed by humans or disease were in protected areas like national parks, but limited resources make it difficult for people to adequately protect gorillas and support the people who live near them. This tragic news
underscores the importance of zoos in educating North Americans about the essential
role of wildlife in maintaining the health of the planet, the plight of wild animals and
nearby human populations, and what we here in North America can do to stop current trends toward extinction worldwide.


Program Goals

  • Research: Science guides much of the management practices of the SSP.
    Find out more about what research projects are currently being conducted or supported by the SSP.
  • Education: Public outreach is vital to increasing awareness about the status of gorillas in zoos and in the wild. Find out more about gorillas and how you can get involved.
  • Advocacy: Great apes face a myriad of challenges in today's world.
    The Gorilla SSP is committed to taking a stand on some of the critical issues facing apes as well as promoting optimal care in zoos.
  • Conservation: Critically endangered in their native Africa, gorilla populations are perilously low due to several factors including deforestation, disease and the bushmeat crisis. The SSP supports in situ activities that address these issues.
  • Husbandry: The people that look after gorillas in accredited zoos have
    some of the most rewarding yet challenging jobs around. The SSP serves these institutions by providing contemporary information about the proper care and management of gorilla groups in a variety of settings.

The SSP is a completely volunteer organization administered by a group of professionals
that care about gorillas and gorilla issues. Find out more about the people behind the
SSP here.


Although programmatically supported by AZA and our member zoos, any funding for our efforts is from independent granting programs or from the sales of our official Gorilla SSP merchandise. Please check out our products and support our program!
