The Petite Terre natural reserve, officially created in 1998, is one of the ecological jewels of the region, both on the marine and terrestrial levels. It is indeed a major natural space for the conservation of habitats and biodiversity in the Guadeloupe archipelago.

The value of this site is due to the presence of one of the most important populations of iguana in the Lesser Antilles. It is also a spawning place for several species of marine turtles, which also shelters a stand of guaiac, a small tree protected by dense wood that has practically disappeared in the Lesser Antilles.
