Geography
The Chimalapas region is in the Isthmus of Tehuantepec, and the region's mountains form part of the divide between Mexico's Pacific watersheds to the south and Gulf of Mexico watersheds to the north. The montane forests are bounded by the lowland Petén–Veracruz moist forests on the north. The Chiapas Depression dry forests lie to the northeast. The montane forests adjoin the Sierra Madre de Oaxaca pine–oak forests on the west, and the Central American pine–oak forests to the east. The Southern Pacific dry forests lie to the south between the mountains and the Pacific Ocean.Climate
