What Can You Do? Population & Range

 Report Suspicious Activities Study Taking from the Parks is illegal, and can ( peninsularis) threaten population health. Report any suspected activity to Park officials.

 Conserve Natural Resources Central Florida Water is a precious resource, and is not unlimited. Freshwater We must all do our part to conserve and preserve (Pseudemys concinna such resources so that they are available in the fu- Research Group suwanniensis) ture.

 Donate Time or Money Parks rely on external funding not only to expand their programs, but to continue those already in Florida Redbelly Cooter place. Research done by many groups is often paid (Pseudemys nelsoni) for by the researchers involved. Even small dona- tions of time or money add up!  Educate Yourself, Speak Out, & Get Creative!
