Conservation is a key component of Cosley Zoo’s mission.

We demonstrate our commitment to conservation on a daily basis by participating in environmentally friendly practices such as recycling, using a rain barrel to collect water for plants, re-purposing materials rather than buying new ones, minimizing plastic waste by providing plastic bags and straws to guests on request only, and installing energy-efficient lighting. We also participate in several large-scale conservation initiatives.

The World’s Tallest Mammal

In the past few years, giraffe numbers in the wild have decreased by 40% due to illegal hunting and habitat destruction. Once numerous there are now less than 100,000 giraffe left throughout Africa. AZA-accredited zoos and their partners are working collectively to help save giraffe through education, scientific research, fieldwork, and public awareness.

One of the Most Endangered Canids in the World

The red wolf is the only canid solely native to the United States. Currently, 27 facilities accredited by the Association of Zoos & Aquariums (AZA) are working together to increase the wild population of the red wolf through captive breeding and reintroduction programs implemented by AZA’s Species Survival Plan program and partnerships with government agencies, non-profits, and research facilities.

Illinois Endangered Reptile

Due to illegal capture, loss of habitat, predation, and vehicle and fishing accidents, this once-numerous local resident is now struggling to survive. Your donations will help Cosley Zoo and its local partners, like The Forest Preserve of DuPage County, in efforts to rear young turtles for release and improve the quality of their natural wetland habitat. Donations will fund continued research and purchase food and equipment vital to the long-term success of this project.
