In general Chiapas has a humid, tropical weather. In the north, in the area bordering Tabasco, near Teapa, rainfall can be more than 3,000 mm (118 in) per year . In the past, natural vegetation at this region was lowland, tall perennial rainforest, but this vegetation has been destroyed almost completely to give way to agriculture and ranching. Rainfall decreases moving towards the Pacific Ocean, but it is still abundant enough to allow the farming of bananas and many other tropical crops near Tapachula. On the several parallel "sierras" or mountain ranges running along the center of Chiapas, climate can be quite temperate and foggy. This allows the development of cloud forests like those of the Reserva de la Biosfera el Triunfo, home to a handful of quetzals and horned guans.
