This unique Tamaulipan Matorral ecoregion lies in Northern Mexico with its southern limit along the line between the nearctic and neotropical realms.
The Tamaulipan matorral constitutes a unique assemblage of plant and animal species, and due to the geological history of the region, has outstanding biodiversity features.
Of the 151 species of endemic agavaceae that live in Mexico, 75 have restricted distributions in areas that served as "ecological" islands in the past; the Tamaulipan matorral is one of these areas.
