Nature Reserve (Culebra National Wildlife Refuge)

Isla Culebrita (little Culebra, little snake) is a small, uninhabited island off the eastern coast of Culebra, Puerto Rico and is part of the Puerto Rico Archipielago. Together with Cayo Botella off the northwestern point, and Pelá and Pelaita to the west, it belongs to the barrio Fraile of Culebra. It is a nature reserve and is part of the Culebra National Wildlife Refuge. The island is home to Culebrita Lighthouse, one of the oldest lighthouses in the Caribbean. Culebrita is only accessible by private boat from the main island of Culebra.[1]

Culebrita is a coral island approximately 1 mile in length. It is roughly y-shaped with three branches extending from the island's center.

There are six beaches on Culebrita, the chief one being Playa Tortuga (Turtle Beach) on the north side of the island. The beach is named for the many sea turtles that use the beach for breeding grounds and the surrounding waters for grazing. Sea turtles Tina and Ike call Playa Tortuga home. The other two large beaches are Trash Beach and West Beach. Because Trash Beach is located on the windward side of the island, debris is often blown onto this beach. This is how the beach gets its name. West Beach is where the water taxis from Culebra Island dock.[2]

There are also large tidal pools on the east side of the island where people lounge as if they were large baths. The pools trap small sea life at low tide. The west side of the island contains two lagoons. The Culebrita Reef lays off the southern coast of the island.


Isla Culebrita has two shallow lagoons, the largest of which, Laguna de Molino (Mill Lagoon), is located in northwest branch of the island. It covers approximately 5.5 acres (2.2 ha) and is about 3 feet (0.91 m) below sea level. The second lagoon, referred to as the eastern tidal flat, is located near the middle of the island's west coast and covers about 0.9 acres (0.36 ha). Both lagoons are bordered on the seaward-side by a small mangrove fringe.[3] These wetlands are an important habitat for some of the local wildlife.

Flora and fauna[edit]

In 2006, an environmental and cultural resource survey of Culebrita was carried out by Southeastern Archaeological Research (SEARCH) of Jonesville, Florida and Ellis Environmental Group, LC, in conjunction with the U.S. Army Corps of Engineers (USACE), Huntsville in order to identify “cultural resources, sensitive habitats, and endangered plants and animals that may exist” on Isla Culebrita. During the survey, a total of 97 plant species were recorded, none of which are state or federally threatened or endangered species. In addition, 32 birds, 4 reptiles, and 2 mammikhhjre recorded. Of these animals, one federally endangered species, the brown pelican (Pelecanus occidentalis) and one threatened species, the white-cheeked pintail (Anas bahamensis) were observed. Endangered green sea turtles (Chelonia mydas) were also observed on the island.[3]
