Little Sandy National Wildlife Refuge protects 3,802 acres of Sabine River floodplain in Wood County, Texas, preserving a bottomland forest of oxbow lakes, shrub swamps, and one of the last substantial blocks of old-growth bottomland hardwood forest in the state. Unlike most national wildlife refuges, it is not open to the public and remains privately owned under a conservation easement rather than direct federal ownership. Its origins trace to land assembled between 1898 and 1902 for the Little Sandy Hunting and Fishing Club after Dallas sportsmen discovered the area near Little Sandy Creek. The protected area was established as a national wildlife refuge in 1986.
