Everglades National Park monitors manatees by tagging them and tracking them through aerial surveys. In 2005, scientists observed 176 adults and 7 calves in park waters. The surveys revealed that manatees frequently enter tidal creeks to obtain freshwater for drinking and refuge during cold weather. Park scientists also evaluate manatee health by capturing individuals and taking biological samples for laboratory study.

Many of the orchids found within the Everglades are "epiphytic," growing on host trees that are used for support. This adaptation allows a variety of plants to grow in an otherwise harsh environment.
