熱帯雨林
There are four principal ecosystems in the state: tropical rainforest, tropical savannah, beaches and wetlands. Tropical rainforest dominates most of the state due to the high levels of rainfall the area receives. However, what exists today is only a fraction of what used to be, as much of the forest area has been over-exploited by man, mostly through logging and slash-and-burn agriculture. Most of the intact rainforest is found in the municipalities of Tenosique, Balancán, Macuspana, Teapa, Tacotalpa, Cárdenas and Huimanguillo.
