Is a large region in eastern Honduras and Nicaragua that encompasses the largest wilderness area in Central America. It has one of the earth's last great tracts of primary forest. An area of biological and cultural variety, La Mosquitia includes diverse ecosystems: mangrove swamps, lagoons, river, savannas, and tropical rain forest. Since 1972 biologists, forestry workers, and conservationists have been working to develop a system of parks and reserves in Honduras. One of these parks, the Rio Platano Biosphere Reserve, was declared a World Heritage site by UNESCO in 1976. The Reserve will keep intact one of the most valuable tracts of primary tropical forest left in Central America
