Big Thicket National Preserve is located in Southeast Texas, near the city of Beaumont and 75 miles northeast of Houston. The preserve consists of nine land units and six water corridors encompassing more than 113,000 acres. The Big Thicket often referred to as a "biological crossroads," is a transition zone between four distinct vegetation types - the moist eastern hardwood forest, the southwestern desert, the southeastern swamp, and the central prairies. Species from all of these different vegetation types come together in the thicket, exhibiting a variety of vegetation and wildlife that has received global interest.

The Big Thicket Association, a 501(c)3 organization, founded in 1964, was formed to save remnants of the once extensive historic Big Thicket forests with its remarkable diversity. The Association's efforts led to the establishment of the Big Thicket National Preserve in 1974 (a National Park System Unit, the first National Preserve). Threats to the fledgling Preserve have proliferated over the years and in 2003 the Preserve was designated by the National Parks Conservation Association as one of America's Ten Most Endangered National Parks, and in 2007, the Neches River (part of the Preserve) was named by the American Rivers Association as one of America's Most Endangered Rivers.
