Corcovado
Corcovado National Park protects major habitats including a montane forest, which covers more than half the park; a cloud forest, located in the highest region, richly populated by oaks and tree ferns; swamp forests, flooded practically year-round; a holillo forest, predominated by palms; a mangrove swamp, located on the estuaries of the Llorona, Corcovado and Sirena Rivers; and a freshwater herbaceous swamp. The park is home to some 500 species of trees-equivalent to a quarter of all the tree species in Costa Rica. Some of the larger trees include the purple heart, poponjoche, nargusta, banak, cow tree, espave and crabwood.
