The Puerto Rican dry forests are a tropical dry forest ecoregion located in southwestern and eastern Puerto Rico and on the offshore islands. They cover an area of 1,300 km2 (500 sq mi). These forests grow in areas receiving less than 1,000 mm (39 in) of rain annually. Many of the trees are deciduous, losing their leaves during the dry season which normally lasts from December to April.
The Guánica State Forest, popularly known as the Guánica Dry Forest is a subtropical dry forest located in southwest Puerto Rico. The area was designated as a forest reserve in 1919 and a United Nations Biosphere Reserve in 1981. It is considered the best preserved subtropical dry forest and the best example of dry forest in the Caribbean.

The Northeast Ecological Corridor Nature Reserve (NECNR) refers to an area designated as a protected Nature Reserve located on the northeast coast of Puerto Rico, between the municipalities of Luquillo and Fajardo. Specifically, the lands that comprise the NEC are located between Luquillo's town square to the west and Seven Seas Beach to the east, being delineated by PR Route # 3 to its south and the Atlantic Ocean to its north. It was decreed as a protected area by former Puerto Rico Governor Aníbal S. Acevedo-Vilá in April 2008, a decision reversed by Governor Luis G. Fortuño-Burset in October 2009, although he later passed a law in June 2012 re-designated as nature reserve two-thirds of its lands, after intense lobbying and public pressure. Later, in 2013, Governor Alejandro García-Padilla signed a law declaring all lands within the NEC a nature reserve. The area comprises 2,969.64 acres, which include such diverse habitats as forest, wetlands, beaches, coral communities, and a sporadically bioluminescent lagoon. The Corridor is also home to 866 species of flora and fauna, of which 54 are considered critical elements, meaning rare, threatened, endangered and endemic species classified by the Puerto Rico Department of Natural and Environmental Resources (DNER), some even designated as critically endangered by the International Union for Conservation of Nature and Natural Resources (IUCN). These include, among others, federally endangered species such as the plain pigeon, the snowy plover, the Puerto Rican boa, the hawksbill sea turtle and the West Indian manatee. The beaches along the NEC, which are 8.74 kilometers long are important nesting grounds for the leatherback sea turtle, which starts its nesting season around April each year.
Rio Abajo State Forest is a forest preserve in Puerto Rico owned by the Department of Natural Resources and one of the 20 state forests in the island. It was designated a National Natural Landmark in 1980 and constitutes an area of 3,590 acres. It consists mostly of subtropical wet and moist karst forest. Mogotes and sinkholes fill the landscape. The forest preserve is located in the municipalities of Arecibo and Utuado. In addition to its ecological value the forest also contains a number of archaeological sites.
Cerrillos State Forest is one of the 21 state forests in Puerto Rico. It is located in barrio Maragüez, in the municipality of Ponce, and covers 200 cuerdas of valleys and mountains in the foothills of the Cordillera Central mountain range.

John Jeffrey Ewel is an emeritus professor and tropical succession researcher in the department of biology at the University of Florida. Most of his research was conducted through experimental trials to understand ecosystem processes in terrestrial and tropical environments. The results of the research provided the ability to further comprehend forest structure and management, as well as its nutrient dynamics. The primary research conducted dealt with the beginning stages of the regrowth and recovery following agriculture practices. Ewel also participated in studies regarding invasive species and restoration ecology.
Elvira Cuevas Viera is a Puerto Rican ecologist. She is a professor in the department of biology at University of Puerto Rico, Río Piedras Campus where she serves as director of the Center for Applied Tropical Ecology and Conservation.
Caño Tiburones is a wetland and nature reserve located in the northern coast of Puerto Rico in the municipalities of Arecibo and Barceloneta. This is one of the largest wetlands in Puerto Rico, covering almost 7,000 acres. A large portion of the swamp, located in Arecibo, is protected as the Caño Tiburones Nature Reserve.

This forest is located in the southeastern foothills of the Central Mountain Range or Cordillera Central, in the municipalities of Sabana Grande and Yauco. Most of the forest, particularly the lower parts, are of secondary growth as the land had originally been deforested and used for cattle grazing, timber production and agriculture. The forest is an important habitat for the endangered Puerto Rican nightjar.
Boquerón State Forest is one of the 20 forestry units that make up the public forest system of Puerto Rico. Despite its name, the Boquerón State Forest is not only located in Boquerón, Cabo Rojo but also spans almost 5,000 acres across the municipalities of Cabo Rojo, Lajas and Mayagüez. The forest area is also known for its limestone cliffs, the lighthouse, and the salt flats which have been a source of salt since the pre-Hispanic era and, dating to 700 C.E., they are considered to be one of the oldest industries in the Americas.
Frank Howard Wadsworth was an American forester, conservationist and researcher. He made important scientific contributions to forestry, through his work in Puerto Rico where he lived from 1942 until his death.
