The Only Rainforest In The US National Forest System
El Yunque National Forest is the only tropical rainforest in the United States National Forest System. Situated in northeastern Puerto Rico, it provides nearly 20% of the island's fresh water. This 28,000-acre national treasure is a vital water source that also sustains the forest's plants and wildlife. Drenched by up to 240 inches of rain each year, it is also the most biodiverse forest anywhere in that system. Its warm weather and constant rainfall shelter hundreds of species, including the Coquí frog that remains one of Puerto Rico's cherished cultural symbols.
History
Originally occupied by the Taino indigenous people, the region was considered a sacred mountain and home of the deity Yúcahu. According to Taino lore, the indigenous God, whose name means giver of yuca, served as the protector and provider of land and life. He was known for providing nourishment through yuca, calming the seas, and protecting the sacred forest from natural disasters.
The forest's name is often traced to the Taino deity and the word 'yuke,' though its exact meaning and origin remain debated. When Spanish colonizers arrived in the 15th century, Taino tradition suggests that Yúcahu could not protect the Taino people against the Spaniards' relentless efforts. However, the Taino people still used the rainforest for defense and as a retreat from Spanish colonialism. The rainforest remained relatively untouched by Spanish forces for centuries before being deemed a crown reserve by Spanish King Alfonso XII in 1876. Its unique climate, biodiversity, and environmental necessity make it worthy of being one of the earliest protected areas in the Americas.
Climate
El Yunque National Forest is known for its tropical rainforest climate, heavy rainfall, and high humidity. Temperatures range from 80°F to 68°F. The national rainforest lives up to its categorization, receiving up to 240 inches per year. Researchers note that the rainforest receives fast, heavy rainfall multiple times a day, even during sunny periods. While that much rain can seem inconvenient to many, it allows the rainforest to do its job. Its heavy rainfall supports eight major rivers and supplies significant amounts of Puerto Rico's water supply. This contribution sustains the rainforest's ecosystem and the wildlife it supports.
Plants and Wildlife
Even though El Yunque National Forest is small, it provides an ecosystem for hundreds of animals and plant life. In fact, the United States Forest Service says it has more biodiversity than any other forest in its system. The 28,000-acre forest hosts more than 240 types of trees. This plant life includes 50 species of orchids, 150 species of ferns, and 8 federally endangered plants. The rainforest is also teeming with diverse wildlife. There are more than 50 bird species, with notable populations of the endangered Puerto Rican Parrot and Emerald Hummingbirds. Plus, the Coquí Frogs, native only to Puerto Rico, are abundant and remain one of the country's most important cultural symbols.
Environmental Threats
While the rainforest is a testament to Puerto Rico's environmental strength and diversity, it has also faced immense threats. Extreme weather, climate change, and human behavior are some of conservationists' biggest concerns. As climate change pushes temperatures higher, it threatens the well-being of sensitive plants and wildlife. Threats are heightened by intense hurricanes, like Hurricane Maria in 2017, that damage habitats, displace animals, and destroy essential infrastructure. Human activity often makes these threats even worse through urban development that removes trees, pollution that endangers wildlife, and tourism that strains ecosystems. Altogether, these combined threats heighten destruction and continue to put America's only rainforest at risk.
Conservation
Protecting El Yunque National Forest is a crucial task that has spanned more than a hundred years. However, it is important to consider where it all began. After the Spanish-American War, the Spaniards were forced to give up Puerto Rico and the rainforest to the United States. After the relinquishment, United States President Theodore Roosevelt deemed it a national forest. He called it the Luquillo Forest Reserve, securing massive donations and land grants and expanding it to more than 20,000 acres.
Known as "The Caribbean National Forest," conservation took a hit during the Great Depression. Revived by President Franklin Roosevelt and the Civilian Conservation Corps, it became a modernized forest with roads, paths, and facilities. It even served as a radar site during World War II. After the war, it remained largely overlooked, visited and occupied mostly by locals. However, an executive order signed by President George W. Bush in 2007 renamed it "El Yunque National Forest," restoring the name associated with its indigenous history and establishing permanent recognition of an essential natural landmark.
However, due to natural and human forces, many of these milestones are becoming obsolete. To evade this, government organizations, like the National Forest System, have implemented several programs. These include protecting endangered species, controlling invasive species, and rebuilding damaged infrastructure. The Puerto Rican Parrot Recovery Program, led by the U.S. Fish and Wildlife Service with the Forest Service and other partners, works to protect the endangered parrots affected by natural disasters and displacement. There are also habitat, landscape, and plant management programs that work to create safety buffers, track animal populations, and clear invasive wildlife. On the human front, there are efforts to rebuild information centers and manage heavy tourism and walking trails.
Wrapping Up
It is no wonder that many marvel at the presence of El Yunque National Forest. With only 28,000 acres, it is a crucial water source and the most biodiverse forest in the United States National Forest System. Its steady warm weather and heavy rainfall make it an environmental landmark. With hundreds of species of wildlife and plants, it remains an ecosystem worthy of protection. Despite the pitfalls of climate change and human degradation, conservation efforts continue to protect the celebrated rainforest.
