Mexico: Oaxaca and Chiapas

This montane forest are found in the Chimpalapas mountains of Mexico. The climate is tropical and subtropical, but varies with altitude. These forests are the largest undisturbed cloud forests in Mexico and Central America (WWF and IUCN 1997). An array of vegetation provides for high diversity of fauna. There are few protected areas in the ecoregion; land clearing for agriculture and human settlements is a major threat to the region.

Justification of Ecoregion Delineation
The delineation’s for these montane forests were derived from several sources. Initial linework follows current landcover maps of Mexico (INEGI 1996). In this case we traced existing montane mesophile forests, pine forests, and pine-oak forest of the NW Sierra Madre de Chiapas in Oaxaca and Chiapas states and lumped together all human modified landscapes which occur within this broader region. In general the linework follows the distributions of montane flora and fauna on an elevational gradient, which is distinct from the surrounding lowland and dry forests (Rzedowski 1978 and pers. comm.). Linework was reviewed and modified at an ecoregional priority setting workshops (CONABIO 1996 and 1997).
