The establishment of the Luquillo Forest Reserve marked a significant step in the conservation efforts of the early 20th century. Covering an area of approximately 28,000 acres in the northeastern region of Puerto Rico, the forest is renowned for its rich biodiversity, featuring numerous species of flora and fauna native to the Caribbean. The decision to designate this area as a federal reserve stemmed from the increasing recognition of the importance of environmental conservation among U.S. policymakers and scientists. The tropical rainforest environment of El Yunque harbors unique ecosystems, including cloud forests and limestone forests, which had been threatened by deforestation and exploitation by agricultural practices.

The designation as a U.S. National Forest not only aimed to protect the natural landscapes but also to promote sustainable land use and recreation. This legislative move underscored the commitment of the United States to environmental stewardship at a time when the conservation movement was gaining momentum on the mainland. It set a precedent for the formation of other national forests across the country, showcasing a balance between natural resource utilization and conservation.

The area also plays a vital role in the cultural heritage of Puerto Rico, being a source of both natural beauty and resources for the local communities. Beyond its ecological significance, the Luquillo Forest Reserve has become an important site for research and education, promoting awareness about environmental issues and the importance of conservation to new generations.
