The geography of Puerto Rico consists of an archipelago located between the Caribbean Sea and the North Atlantic Ocean, east of the Dominican Republic or Hispaniola, west of the Virgin Islands and north of Venezuela. The main island of Puerto Rico is the smallest and most eastern of the Greater Antilles. With an area of 3,515 square miles (9,104 km2), it is the third largest island in the United States and the 82nd largest island in the world. Various smaller islands and cays, including Vieques, Culebra, Mona, Desecheo, and Caja de Muertos comprise the remainder of the archipelago with only Culebra and Vieques being inhabited year-round. Mona is uninhabited through large parts of the year except for employees of the Puerto Rico Department of Natural Resources.
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a tropical and subtropical forest habitat type defined by the World Wide Fund for Nature.
Delonix regia is a species of flowering plant in the bean family Fabaceae, subfamily Caesalpinioideae native to Madagascar. It is noted for its fern-like leaves and flamboyant display of orange-red flowers over summer. In many tropical parts of the world it is grown as an ornamental tree and in English it is given the name royal poinciana, flamboyant, phoenix flower, flame of the forest, or flame tree.
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.
Acer macrophyllum, the bigleaf maple or Oregon maple, is a large deciduous tree in the genus Acer.
Hibiscus tiliaceus is a species of flowering tree in the mallow family, Malvaceae, that is native to the Old World tropics. Common names include sea hibiscus, beach hibiscus, coastalhibiscus, coastalcottonwood, green cottonwood, native hibiscus, native rosella, cottonwood hibiscus, kurrajong, sea rosemallow, balibago (Tagalog), malabago or malbago, maribago, lambago, waru (Javanese), baru or bebaru (Malay), dhigga (Maldivian), pagu (Chamorro), hau (Hawaiian), fau (Samoan), purau (Tahitian), and vau tree. The specific epithet, "tiliaceus", refers to its resemblance of the leaves to those of the related Tilia species.
Annona squamosa is a small, well-branched tree or shrub from the family Annonaceae that bears edible fruits called sugar-apples or sweetsops. It tolerates a tropical lowland climate better than its relatives Annona reticulata and Annona cherimola helping make it the most widely cultivated of these species. Annona squamosa is a small, semi-(or late) deciduous, much branched shrub or small tree 3 metres (9.8 ft) to 8 metres (26 ft) tall similar to soursop.
The Puerto Rican amazon, also known as the Puerto Rican parrot or iguaca, is the only extant parrot endemic to the archipelago of Puerto Rico, and belongs to the Neotropical genus Amazona. Measuring 28–30 cm (11.0–11.8 in), the bird is a predominantly green parrot with a red forehead and white rings around the eyes. Its closest relatives are believed to be the Cuban amazon and the Hispaniolan amazon.
Thespesia grandiflora is a tree in the family Malvaceae of the rosids clade. Its common name is maga. This tree is widely distributed throughout Puerto Rico where it is endemic. Although originally endemic to the humid mountains of limestone in the western and north-central portions of the Island, today it grows everywhere in Puerto Rico due to its extensive cultivation. It is also grown as an ornamental tree in Florida, Hawaii, Honduras and in various Caribbean islands. The maga is mostly used as an ornamental plant, but like the related Thespesia populnea its wood is also valued for its durable timber. The flower was declared the national symbol of Puerto Rico on August 7, 2019.
The fauna of Puerto Rico is similar to other island archipelago faunas, with high endemism, and low, skewed taxonomic diversity. Bats are the only extant native terrestrial mammals in Puerto Rico. All other terrestrial mammals in the area were introduced by humans, and include species such as cats, goats, sheep, the small Indian mongoose, and escaped monkeys. Marine mammals include dolphins, manatees, and whales. Of the 349 bird species, about 120 breed in the archipelago, and 47.5% are accidental or rare.
The Puerto Rican bullfinch or comeñame in Spanish, is a small bullfinch tanager endemic to the archipelago of Puerto Rico. These were previously considered Emberizidae. The Puerto Rican bullfinch has black feathers with orange areas above the eyes, around its throat, and underneath the tail's base. The species measures from 17 to 19 cm and weighs approximately 32 grams.
The Hispaniolan amazon or Hispaniolan parrot, colloquially known as cuca, is a species of Amazon parrot in the family Psittacidae. It is endemic to Hispaniola, and has been introduced to Puerto Rico. The main features that differentiate it from other amazons are the white forehead, pale beak, white eye-ring, blue ear patch, and red belly.
The Caribbean bioregion is a biogeographic region that includes the islands of the Caribbean Sea and nearby Atlantic islands, which share a fauna, flora and mycobiota distinct from surrounding bioregions.
Ficus aurea, commonly known as the Florida strangler fig, golden fig, or higuerón, is a tree in the family Moraceae that is native to the U.S. state of Florida, the northern and western Caribbean, southern Mexico and Central America south to Panama. The specific epithet aurea was applied by English botanist Thomas Nuttall who described the species in 1846.
Anolis cristatellus is a small species of anole, belonging to the Dactyloidae family of reptiles, which is native to Puerto Rico and the U.S. and British Virgin Islands, with introduced populations in locations around the Caribbean. The males of A. cristatellus are easily recognizable by the fin running down the top of the tail, which is known as a "caudal crest". The females also have these crests, but these are smaller than those of the males. It is often quite common in many areas on Puerto Rico, where it can be seen during the day passing the time on the lower parts of tree trunks, or on fences and the walls of buildings in urban areas, sometimes venturing down onto the ground in order to lay eggs, have a snack, or do other cursorial activities. Like many anoles, this species displays the characteristic behaviour of doing push-ups as well as inflating a pizza-like flap of coloured skin on their throat, known as a dewlap, in order to show others how hip they are, and thus attract mates or intimidate rivals.
Sabal causiarum, commonly known as the Puerto Rico palmetto or Puerto Rican hat palm, is a species of palm which is native to Hispaniola, Puerto Rico, and the British Virgin Islands. As its common and scientific names suggest, its leaves are used in the manufacture of "straw" hats.
Chrysophyllum oliviforme, commonly known as the satinleaf, is a medium-sized tree native to Florida, the Bahamas, the Greater Antilles, and Belize. It is also known as damson plum, wild star-apple and saffron-tree. It gets the name "satinleaf" from the distinctive colors of the leaves. The top of the leaf is dark green while the bottom is light brown or copper. This distinctive look makes it a very aesthetically pleasing tree that is commonly used as an ornamental in yards and public spaces.
Cordia sulcata is known commonly as moral, white manjack, or mucilage manjack. It is a tree that can be found throughout the Caribbean islands from Cuba to Trinidad.
Tabebuia heterophylla is a species of tree native to the Caribbean, and is also cultivated. It is also known as Roble blanco, pink manjack, pink trumpet tree, white cedar, and whitewood.
Guilarte State Forest is one of the 20 forests that make up the public forests system in Puerto Rico. The forest is located in the eastern half of the Central Mountain Range or Cordillera Central. The main geographical feature of the forest reserve is Monte Guilarte, which is Puerto Rico's 7th highest mountain at 3,950 feet above sea level. While Monte Guilarte is located in the municipality of Adjuntas, the forest's borders also include parts of Guayanilla, Peñuelas and Yauco.
