La Selva was originally established in 1954 by Dr. Leslie Holdridge as a farm dedicated to experimentation on mixed plantations for the improvement of natural resources management. It was purchased in 1968 by the Organization for Tropical Studies and declared a private biological reserve and station. Since then, it has become one of the most important sites in the world for research on tropical rainforest. Over 240 scientific papers are published yearly from research conducted at the site.
