The present lagoon is a remnant of what was once a large open expanse of water and one of the most important freshwater habitats for migrating and aquatic birds in Puerto Rico.

The lands surrounding the lagoon are being managed to convert agricultural and grazing lands to a forested area for native birds. Through water management the lagoon will be opened for aquatic birds. This challenging management project will take time to accomplish, but it's result will improve habitat for native wildlife.

Historically, almost half the birds recorded in Puerto Rico have been observed in the lagoon and adjcent hills. Visitors have a good chance of seeing a Magnificent Frigatebird, several species of herons, Smooth -billed ani and occasionally the yellow-shouldered blackbird.

In addition to the lagoon, there are uplands that include grassland, abandoned sugar cane fields, In 1996, a parcel (263 acres) of land in the adjcent Sierra Bermeja was added. These hills, geologically some of the oldest in the Caribbean, protect a native forest with many endemic plant species.
