The Puerto Rican moist forests are a tropical moist broadleaf forest ecoregion in Puerto Rico. They cover an area of 7,544 km2 (2,913 sq mi).[2]
Lowland forests
Lowland forests are found throughout the island's coastal lowlands except for the dry southwest. Characteristic tree species include Hymenaea courbaril, Palma de Coroso (Acrocomia media), Nectandra coriacea, and Zanthoxylum martinicense. Trees reach a height of 24 m (79 ft) in the northern portions, but are shorter elsewhere. Several species are adapted to dry periods by being deciduous or semi-deciduous.[2]

Fauna
Puerto Rican moist forests are home to a variety of endemic animal species such as the
Ecological processes
As with most mountainous areas, the forest types change with elevation, exposure and rock type. Superimposed upon these physical factors are forms of natural disturbance such as landslides and hurricanes that allow light-demanding plant species to regenerate.[4] A study in the Luqillo Mountains found that between 1936 and 1988, there were 46 landslides associated with heavy rain, and these created gaps that allowed ferns such as Dicranopteris pectitnata to proliferate.[5]
Conservation and protected areas
A 2017 assessment found that 406 km2, or 5%, of the ecoregion is in protected areas. Forty-two percent of the unprotected area is still forested.[1] Protected areas include El Yunque National Forest, Cambalache Forest Reserve, Maricao State Forest, Monte Choca State Forest, Río Abajo State Forest, and Toro Negro State Forest. The Northeast Ecological Corridor Nature Reserve includes both lowland moist forest and dry forest.
