U.S. Fish and Wildlife Service Mammals of Trinity River National Wildlife Refuge Established in 1994, the 25,000-acre Trinity River National Wildlife Refuge is a remnant of what was once a much larger, frequently flooded, bottomland hardwood forest. You are still able to view vast expanses of ridge and swale floodplain features, numerous bayous, oxbow lakes, and cypress/tupelo swamps along the Trinity River. It is one of only 14 priority-one bottomland sites identified for protection in the Texas Bottomland Protection Plan. This type of habitat is used during migration or nesting by nearly 50 percent of the migratory bird species listed by the U.S. Fish and Wildlife Service. Over 275 species of birds occur in the hardwood forest and associated wetlands in eastern Texas; while over 100 bird species are known to breed there. These forests also support a wide diversity of mammals, reptiles, amphibians, and fish including the federally listed bald eagle and alligator.
