Chiapas' rainforests are home to thousands of animals and plants, some of which cannot be found anywhere else in the world. Natural vegetation varies from lowland to highland tropical forest, pine and oak forests in the highest altitudes and plains area with some grassland. Chiapas is ranked second in forest resources in Mexico with valued woods such as pine, cypress, "Liquidambar", oak, cedar, mahogany and more. The Lacandon Jungle is one of the last major tropical rainforests in the northern hemisphere with an extension of . It contains about sixty percent of Mexico's tropical tree species, 3,500 species of plants, 1,157 species of invertebrates and over 500 of vertebrate species. Chiapas has one of the greatest diversities in wildlife in the Americas. There are more than 100 species of amphibians, 700 species of birds, fifty of mammals and just over 200 species of reptiles. In the hot lowlands, there are armadillos, monkeys, pelicans, wild boar, jaguars, crocodiles, iguanas and many others.

The coastal areas have large quantities of fish, turtles, and crustaceans, with many species in danger of extinction or endangered as they are endemic only to this area. The total biodiversity of the state is estimated at over 50,000 species of plants and animals. The diversity of species is not limited to the hot lowlands. The higher altitudes also have mesophile forests, oak/pine forests in the Los Altos, Northern Mountains and Sierra Madre and the extensive estuaries and mangrove wetlands along the coast.
