Los Haitises has two Holdridge life zones: humid subtropical forest (Bh-S) and very humid subtropical forest (Bmh-S). Broadleaf species in the park include "musk wood" ("Guarea guidonia", locally "cabirma santa"), cigar-box cedar ("Cedrela odorata"), ceiba ("Ceiba pentandra"), West Indian mahogany ("Swietenia mahagoni", Spanish "caoba"), cupey ("Clusia rosea"), and grandleaf seagrape ("Coccoloba pubescens"). There are many species of orchids. Los Haitises contains the greatest abundance of Caribbean mangrove, in which species like red mangrove ("Rhizophora mangle") and white mangrove ("Laguncularia racemosa") predominate. The fauna of Los Haitises is of great variety, and due to the park's diversity of physical geographic zones, it has the greatest diversity of fauna among the protected natural areas in the country. Two endemic mammal species, the Hispaniolan hutia ("Plagiodontia aedium") and the Hispaniolan solenodon ("Solenodon paradoxus"), are threatened with extinction. Being a coastal and marine park, it contains a large variety of birds, including most of the species endemic to the country. These include the brown pelican or "alcatraz" ("Pelecanus occidentalis"), magnificent frigatebird ("Fregata magnificens"), Hispaniolan amazon ("Amazona ventralis"), barn owl ("Tyto alba"), and stygian owl ("Asio stygius"). Some of the bird species found in Los Haitises are not found elsewhere within the Dominican Republic. Los Haitises National Park is a protected virgin forest with little road access. The number of tourists allowed is limited, but since 2000 it has been a relatively popular destination for ecotourism using ecological guides from Sabana de La Mar. "Haiti" (singular) means highland or mountain range in the Taíno language, although the elevation of the park's hills ranges from . There is a multitude of caverns created by water erosion. Native Americans adorned these caverns with pictographs and petroglyphs. The culture or cultures which created these artworks remain unidentified, some of them possibly predating the Taínos. Los Haitises National Park contains spectacular landscapes like the San Lorenzo Bay, the islets (keys), and the mangroves.
