Ecology
The range is noted for its very high biodiversity and large number of endemic species.
The Sierra Madre del Sur pine-oak forests occupy the higher reaches of the range. These forests are part of a chain of Mesoamerican pine-oak forests that stretch from the Southwestern United States to Costa Rica along the American Cordillera.
Lower elevations of the range are covered by tropical dry forests, ecoregions in the Tropical and subtropical dry broadleaf forests Biome. The Jalisco dry forests occupy the western end of the range's Pacific slope. The Southern Pacific dry forests occupy most of the Pacific slope of the range, from Michoacan in the west through Guerrero and Oaxaca. The basin of the Balsas River, north of the Sierra, is home to the Balsas dry forests.
