      Biosphere Reserve Information



  General Description   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.
The site includes the municipalities of Acatlán, Atotonilco el Grande, Eloxochitlán, Huasca de Ocampo, Metztitlán, San Agustín Metzquititlán, Zacualtipán de Ángeles y Metepec. They include 135 communities and ranchers: 78 from Metztitlán, 10 from Eloxochitlán, 13 from St. Augustine Metzquititlán, 10 Huascar de Ocampo, 11 Atotonilco el Grande, 13 Acatlan, and 3 from Zacualtipán de Ángeles y Metepec.
There are five communities within the biosphere reserve that are considered as indigenous, since more than 25% of their population speaks the native Ñha-Ñhu language. They are located in the municipality of Metztitlán and belong to the ethnic group Otomi.

  Brief description   Research activities are extremely important because they provide reliable information for decision-making regarding the management of natural resources. The biosphere reserve regularly receives research results from the studies conducted in the site, and a Forum for Conservation Research, including meetings of a Research Council that is composed of all academic and research institutions working in the biosphere Reserve meets annually. The Research Council is part of the Advisory Council and is thus actively involved in communication of scientific information, decision-making and planning for the local and regional development of the communities living in the biosphere reserve.
