The Tehuacán Valley matorral ecoregion occupies the Tehuacán Valley, Oriental Basin, and adjacent valleys, covering parts of the states of Tlaxcala, Puebla and Oaxaca. The valleys lie in the rain shadow of the surrounding mountain ranges, and are drier than the surrounding ecoregions.
The Tehuacán Valley matorral is a center of plant diversity, with over 2700 species, of which approximately 30% are endemic. It is a center of diversity for species of Agave, Hechtia, Salvia, and cactus.
The ecoregion has a number of distinct plant communities.
The ecoregion is notable for its diversity of birds and bats. Of the 90 species of birds present, 10 are endemic, including the ocellated thrasher (Toxostoma ocellatum), and bridled sparrow (Aimorphilla mystacalis). 34 species of bats inhabit the ecoregion, of which 18 are endangered, vulnerable, or rare.
A 2017 assessment found that 1,594 km², or 16%, of the ecoregion is in protected areas.[3] Protected areas include the Tehuacán-Cuicatlán Biosphere Reserve.
