About Us

The Caribbean Ecological Services Field Office (CESFO) was established in 1974 as part of the U.S. Fish and Wildlife Service’s Southeast Region. We have jurisdiction on Federal Trust Species (i.e., at-risk species, federally listed species, migratory birds and inter-jurisdictional fish) in Puerto Rico and the U.S. Virgin Islands (USVI; St. Thomas, St. John, and St. Croix).

    Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.
