Barranca de Metztitlán Biosphere Reserve, Mexico

The State of Hidalgo delimits physiographic provinces of Sierra Madre Oriental and Eje Neovolcánico. Its irregular boundaries delimit the biosphere reserve, although the latter is mainly situated within the Sierra Madre Oriental physiographic province. The shape of the site is quite long and irregular.
The mild climate is related to altitude. While the mountains to the east and northeast reach 1,800 to 2,600 m, in the plain the elevation is approximately 1,200 to 1,300 m. The factors contributing to higher temperatures in the Barranca are the latitude and the adiabatic gradient.
