Sierra Madre del Sur pine-oak forests
|Sierra Madre del Sur pine-oak forests|
|Biome||Tropical and subtropical coniferous forests|
|Borders||Balsas dry forests, Tehuacan Valley matorral, Sierra Madre de Oaxaca pine-oak forests and Southern Pacific dry forests|
|Area||61,200 km2 (23,600 sq mi)|
The pine-oak forests occupy the higher slopes of the Sierra Madre del Sur range, which runs east and west parallel to Mexico's southern Pacific Coast. The forests are surrounded by tropical dry forests at lower elevations; the Jalisco dry forests to the west; the Balsas dry forests to the north, in the basin of the Balsas River, and the Southern Pacific dry forests to the south and east along the Pacific coast.
The chief plant communities are oak forests, cloud forests, pine-oak forests, and fir forests. The plant communities vary with elevation and rainfall.
The oak forests occur between 1900 and 2500 metres elevation (6,200-8,200 feet). Cloud forests grow at 2300 metres (7,500 feet); pine-oak forests grow at 2400–2500 metres (7,900-8,200 feet); and fir forests grow above 3,000 metres (9,800 feet).
