The Puerto Rico Natural Resources Ranger Corps (Spanish: Cuerpo de Vigilantes de Recursos Naturales) is the law enforcement conservation officers for the Commonwealth of Puerto Rico.
Its primary mission is to protect endemic plants and animals of Puerto Rico, prevent the introduction of invasive animals and plants and prosecute any person who violates environmental laws.
The Corps also serves as the police in all areas under the jurisdiction of the Department of Environment and Natural Resources.
Since 2004 the agency has had 310 rangers and has been unable to train new members due to lack of funds.
