El Yunque is a tropical rainforest in northeastern Puerto Rico and is the only tropical rainforest in the U.S. National Forest Service. With an average rainfall of 120 inches a year, El Yunque has a very diverse ecosystem, hosting hundreds of unique plant and animal species, including the Island’s famous coquí frog. It’s estimated that the rainforest is home to over 240 species of plants and trees along with rare wildlife, including the Puerto Rican parrot which is one of the ten most endangered species of birds in the world with only around 30 alive in the wild. It frequently rains in El Yunque, sometimes as much as four times a day and it contains six rivers, several streams, and waterfalls. Landslides are a frequent occurrence in the rainforest and hunting is not allowed.
