| El Yunque’s biodiversity makes it unique among other forests in the United States National Forest System. Frequent rain showers generate close to 100 billion gallons of rainwater a year and conspire with Puerto Rico’s warm tropical climate to accommodate over 240 species of native trees, 50 species of orchids, and 150 species of ferns. Almost a third of the tree species are native to Puerto Rico and the Virgin Islands, and 10 percent of them are endemic to El Yunque and cannot be found anywhere else in the world. The forest’s animal life is dominated by reptiles, amphibians, and birds, including the endangered ‘Higuaca’ or Puerto Rican Parrot. The forest attracts over a million visitors each year, who come to hike its more than 13 miles of trails while enjoying the lush scenery and fresh mountain air. |
