Piedras Blancas
Piedras Blancas National Park part of the Osa Conservation Area in the south of the coastal province of Puntarenas. The National Park protects rainforests and beaches near the Golfo Dulce on the Pacific Coast. This is park is famous for its diversity in birds.
The rugged mountains and watersheds of both the Esquinas and Piedras Blancas rivers are dense rainforest which is home to a number of rare tropical trees and the habitat of many species of birds, mammals and reptiles.
Some of the park has remained in private hands, however a charitable organisation Rainforest of the Austrians (Regenwald der Osterreicher) has been raising funds and purchasing these, which up to 2008 had moved 37 km² of land in the area into public ownership. The Costa Rican government, the hydroelectric company Tenaska (carbon offset joint implementation), The Nature Conservancy and the Gordon and Betty Moore foundation have also purchased land in Piedras Blancas, bringing the total protected area within the park to more than km2 or 80%.
