SIERRA DE HUAUTLA

 
       
  General Description   Sierra de Huautla Biosphere Reserve (REBIOSH) is located in Balsas Basin and constitutes a rich reservoir of endemic species to Mexico. Its rough topography allows an altitudinal variation from 700 to 2,240 m.a.s.l. (metres above sea level) It presents a broad of ecosystem representativity, from which we can highlight due to their coverage, the following: low deciduous forest, gallery vegetation, pine-oak forest. Currently the REBIOSH, together with the Department of Environmental Education (DEA) of the Sierra de Huautla Center of Environmental Education and Research (CEAMISH) of the State of Morelos Autonomous University (UAEM) coordinate all the activities within the reserve, such as ecotourism and exploitation of non-timber products by communities inside and outside the REBIOSH.
REBIOSH is included in two physiographic provinces. The first one includes the Eje Neovolcánico, particularly the subprovince of the South of Puebla, that is located in the South and East region of the REBIOSH and composed by a great variety of volcanic rocks and continental sediments, that include lacustrine gypsum deposits from the Miocene. The second province, located in the Western region of REBIOSH, belongs to the Sierra Madre del Sur. It is represented by the subprovince of the Lakes and Volcanoes of Anáhuac, in which hills and high plains at altitudes from 900 to 2400 m.a.s.l. can be observed. Most surface runoff in REBIOSH is from storms and they only present discharge during the rainy season. The permanent rivers are Amacuzac and Cuautla, where irrigation takes place along their fertile lowlands. The discharge that comes from Cerro Frío is stored in the Emiliano Zapata dam and it enables irrigation of the Tilzapotla land. In general, water is a limiting resource in REBIOSH; the mountains of Cerro Frío and Huautla function as generators, regulators and protectors of hydrological, superficial and groundwater resources for the local inhabitants and those that live downstream in the State of Guerrero.
