Understanding the status of endangered species

Woodland Park Zoo is home to more than 50 threatened species. These wildlife ambassadors remind us what’s at stake in a world under pressure, and inspire us to take action. While browsing this website, you’ll encounter the following terms used to describe the state of species populations in the wild:

When terms such as "endangered", "threatened" or "extinct" are used, they refer to the current state of conditions a population of a species exists in in the wild.

Categories used for status on this site

Facing a high risk of extinction in the wild.

Does not qualify for one of the other categoires, but is close to qualifying or likely to qualify in the near future.

Does not qualify for any other category and is currently widespread or abundant.

Not evaluated, or not enough data exists to make an accurate determination of status.

Zoos are responding to species decline and are leading the way in preserving animal populations. Captive breeding of threatened and endangered animals is conducted through the Species Survival Plan (SSP). The goal of each SSP is to maintain and enhance genetic in order to maintain healthy captive populations. SSPs are coordinated through the Association of Zoos & Aquariums (AZA).

Accredited zoos today play an irreplaceable role in the species survival equation. Scientific research being conducted in zoos on species’ health, social behavior and reproduction are major contributions to the knowledge base on which field conservation relies.
