Boquerón State Forest is one of the oldest forests in the Puerto Rico state forest system. It was proclaimed and designated a forest preserve in 1918 by Puerto Rico governor
Arthur Yager with the purpose of preserving the
mangrove biomes in Cabo Rojo and Lajas. Two additional segments, the Guayacán and Cuevas Keys, were added in 1943. The areas of the Molino mangroves, Los Morrillos (famous for its
lighthouse) and the
Guaniquilla Lagoon and surrounding mangroves were annexed to the Boquerón State Forest in 1980. • Mangrove forest of
