Despite an abundance of marshy, often inaccessible areas, the Chesapeake Bay region supports a surprising number of land mammals. The array of species includes white-tailed deer, sika deer, black bear, coyote, red fox, gray fox, skunks, opossum, groundhogs, beavers, muskrats, and others.
Herps are common throughout the watershed although most species’s ranges are habitat specific. The upper portions of the watershed contain amphibians, with frogs and salamanders being common. High salinity habitats contain higher numbers of turtles.
