Palo Verde is one of the areas of greatest biological diversity in Costa Rica. It contains about 15 distinct habitats, which are created by the topology of the area, the physical conditions, the chemistry and geology of the ground, including drainage, water retention, and the effect of the tides.
The natural hydrologic system of Palo Verde creates conditions that, from September to March, support the most important concentration of aquatic and wading birds in Central America, both resident and migratory. Monkeys, white-tail deer, and coatimundis can all be seen in this zone.
We are working with Costa Rican and international volunteers to protect one of the most diverse forests in Costa Rica, one of world-wide renown and importance, according to the Ramsar Convention. We do maintenance of trails and installations, repair of the roads, and cleaning. We support the officials responsible for the area. Volunteers also are in charge of visitor service, and of watching and care of the area to help prevent environmental damage and illegal activities.
