Conservation Value of Las Alturas
By Catherine Lindell

Las Alturas plays a unique role in the conservation of biodiversity in Central America for several reasons. First, it is located on the Pacific slope of the Talamanca Mountains in Costa Rica. This area is considered by the World Wildlife Fund to be one of the "Global 200", one of the 238 most valuable ecoregions on earth with respect to conservation of the world's biodiversity (Olson & Dinerstein 2002).

Second, the property is immediately adjacent to Las Tablas protected zone, which is part of the Amistad Biosphere Reserve, the largest tract of forest in Central America. Its proximity to the reserve means that Las Alturas plays a vital role in providing a buffer between the park and the heavily agricultural landscape beyond Las Alturas.

Third, Las Alturas is extremely large for a privately-owned property (10,000 hectares) and most of the land area is covered with mature forest. Tropical forest supports very high numbers of species of all taxonomic groups, from fungi to butterflies to birds to mammals.

Fourth, the biodiversity supported on the property is enhanced by the maintenance of open and second-growth areas which provide habitat for species not found in forest. Finally, the owner of the property is committed to conservation and the preservation of native species.


Research on birds on the property indicates its conservation value. More than 200 species of birds have been detected and, because sampling techniques often miss rare species, the actual number of species is likely more than 300. Many of these bird species successfully nest on the property. Bird species that have disappeared from areas like the Central Valley of Costa Rica, for example the white-throated robin, are found in abundance at Las Alturas. Several migratory species that are on the U.S. Fish and Wildlife Service's National List of Birds of Conservation Concern (U.S.F.W.S. 2002) have been observed on the property, including the wood thrush, the golden-winged warbler, the worm-eating warbler, the Kentucky warbler, and the Louisiana waterthrush.
