Only 5% of the native riparian, floodplain, and wetland habitats remain along the lower Rio Grande and its local tributaries.[according to whom?] However, the diversity within these fragments adds up to a significant 1,200 species of native plants, 700 species of vertebrates (including nearly 500 bird species), and 300 species of butterflies. Eleven different biological communities exist on the National Wildlife Refuge, from the Chihuahuan Desert thorn forest to tidal wetlands.
