SIERRA DE MANANTLÁN

 
       
  General Description   The reserve is located in the transition of the Nearctic and Neotropical realms and encompasses parts of the Sierra Madre del Sur, with a wide range of altitudes, climates and soils. The effects of tectonic and volcanic activities and erosion are notable within the reserve. Different types of forests are present in the reserve including mesophytic, cloud, and dry deciduous and semi-deciduous tropical forests. Anthropologists know the region as ‘Zona de Occidente’, an area notably different to the rest of Mesoamerica. Some ceramic remnants, figurines and graves have been found, but there is little other material evidence. More than 40,000 people (2002) live in the Sierra de Manantlán, engaged mainly in agriculture (corn, beans, tomatoes, sugarcane, watermelon, mangoes), livestock grazing, timber production, and extraction of wood for fuel and mining of coal or minerals. Their living conditions are poor and marginal. Being one of the forgotten groups in Jalisco, their land rights have been ignored by commercial timber companies and by local administrators. The biosphere reserve with its focus on people as an integral part of the ecosystem would appear well fitted to address the challenges of conserving wild relatives of important crops. An example is the wild maize (Zea diploperennis), discovered in the 1970’s that led to the biosphere reserve designation in 1988. Populations of the wild annual relative (Mays ssp. parviglumis) and the ‘Tabloncillo’ and ‘Reventador’ races of maize, traditional for this area, are further targets for conservation .The major goal of the reserve is to implement an alternative productive diversification of agrarian communities in ecotourism, sustainable forest management, agriculture and handicraft.
