This is quite a complex project to precis. Run by the Area de Conservation Guanacaste under the control of the internationally respected ecologist Professor Dan Janzen of the University of Pennsylvania, it is a land and forest purchase project in the northern highlands of Costa Rica linking the established Reserve of Santa Rosa in the Pacific lowlands with the National Parks of Guanacaste and Rincon de la Vieja. This provides a continuous bridge or corridor of forest from the Pacific lowland dry gallery forest to the highland cloud forests.
