Wildlife Comes First

As the name implies, this refuge is a place where wildlife always takes priority over humans. As noted below, St. Marks is a home for endangered and rare species, several of which nest and raise their young here. St. Marks’ biologists will close certain sections of hiking trails on the refuge during the breeding season to ensure that breeding activities are not interrupted. Always be respectful of wildlife and observe from a distance.

An Abundance of Wildlife

A list of 38 species of amphibians, 69 species of reptiles and 44 species of mammals have been compiled from observations, consultation with experts in respective fields, and literature research.

Some species are more common seasonally and some are nocturnal. Look for evidence such as tracks, burrows, grass tunnels and other signs of activity. Careful eyes and attentive ears can uncover numerous clues to the variety of wildlife present.

St. Marks is also an important sanctuary for birds. Over 250 species occur annually and the total number of species recorded here is over 350. Read more about the birds of St. Marks and birding in the Refuge.
