The Biological Research Station is located inside Palo Verde National Park.
[1] Palo Verde National Park was declared a Wildlife Refuge during the 1970s; over 60 different species of birds used the Laguna, or wetland, as a migratory stop.
In the 1990s, the park was put on the Ramsar list of wetlands of international importance and also on the Montreux Record.
[2] Mammals found near the station include the mantled howler monkey, the white-throated capuchin, and the collared peccary.
Professors from the United States and the University of Costa Rica offer courses at the station, and ecologists give tours for visitors.
