The Saint Louis Zoo has been involved in saving endangered species and their habitats around the world for many years - and with much success. We have witnessed dozens of cheetah births at the Zoo, hatched and reared endangered Micronesian kingfishers and returned Puerto Rican crested toad tadpoles to ponds in their native homeland - to name only a few successes. However, the rising need to sustain wildlife in wild places required the Zoo to take this involvement to another level. In recent years, we have established two institutes dedicated to creating a sustainable future for wildlife and people around the world.

WildCare Institute

In 2004, the Saint Louis Zoo established the WildCare Institute. From the streams of the Missouri Ozarks to the Sahara desert in North Africa, the Zoo is pledged to support critical initiatives in places where animals are threatened by shrinking habitats, poaching and disease.

Institute for Conservation Medicine

The Saint Louis Zoo Institute for Conservation Medicine takes a holistic approach to research on wildlife, public health, and sustainable ecosystems to ensure healthy animals and healthy people.


Just one family making the change to reusable bags can keep 1,500 plastic bags out of the ocean each year! By saying #byetobags, you can make a difference for the world’s oceans.  

Do-It-Yourself Conservation

You can personally help protect wildlife by doing earth-friendly activities in your home and at your work every day, and when you travel.

We Conserve Resources

The Zoo recognizes that reducing water, energy, and material resources in our own operations is critical to our conservation mission as is educating our visitors about things they can do to reduce their impact.
