Murici Ecological Station an average of . The dominant vegetation is dense rainforest in the Atlantic Forest biome. In the best preserved areas, mostly at the higher elevations, the forest forms a fairly uniform closed canopy up to high that provides shade and retains moisture. Tree species include murici ("Byrsonima sericea"), "Schefflera morototoni", "Parkia pendula", "Tabebuia" species, "Pseudobombax" species, "Bowdichia virgilioides", "Tapirira guianensis", "Handroanthus impetiginosus" and "Protium" species. The understory contains seedlings of trees, palms such as "Euterpe catinga", and many lianas and epiphytes, such as "Araceae", "Orchidaceae" ("dimerandra" species, "Dichaea" species, "Rodriguezia" species, "Cattleya labiata", "Pleurothallis" species, "Epidendrum" species, "Oncidium" species and
