El Yunque National Forest

Situated on the United States island of Puerto Rico, the El Yunque National Forest was previously recognized as the Luquillo National Forest and the Caribbean National Forest. The second highest mountain peak in the forest is also the named El Yunque. It is the sole tropical rain forest in the whole of United States National Forest System.

El Yunque National Forest – History

Set up on 17 January 1903 as the Luquillo Forest Reserve by the General Land Office, the National Forest in Puerto Rico was a region originally set aside for forest land in the year 1876 by the King Alfonso XII of Spain, and it represented one of the earliest forest reserves in the Western Hemisphere. Occupying an area of 65,950 acres, it got promoted to the status of a National Forest in the year 1906. It was then renamed as Caribbean National Forest on the 4 June 1935.

El Toro

An Executive Order issued by President George W. Bush on the 2nd of April, 2007 finally altered the name of the Forest to El Yunque National Forest, a name better expressing the cultural and historical sentiments of the people of Puerto Rico. Owing to its location on the south of the Tropic of Cancer, Puerto Rico has a tropical climate and there is no wet or dry season in particular in the El Yunque as it experiences rainfall throughout the year. The temperatures as well as length of daylight are more or less same all through the year. These are the factors that contribute to the year-round growth of the forest plants.
