National System of Conservation Areas

National System of Conservation Areas or SINAC, (—SINAC), is part of the Ministry of Environment and Energy or MINAE of Costa Rica. It is the administrator for the nation's national parks, conservation areas, and other protected natural areas.
Created in 1994, it combined previously three separate organisations that had previously managed laws relating to national parks, wildlife, and forestry. 
Scope.
SINAC oversees over 160 protected areas, of which 26 are designated National Parks. Other areas are designated wildlife refuges, biological reserves, national monuments, forest reserves, national wetlands, and protected zones.
The entire country of 12,596,690 acres (50,977 km²) is under the jurisdiction of eleven large Conservation Areas which were created in 1998, overseen by divisions of SINAC. Over 25% of the national territory i.e. 3,221,636 acres (13,037 km²) is included in the national parks, refuges, and protected zones within these eleven Conservation Areas.
Costa Rica's progressive policies on environmental protection and sustainable eco-tourism in the National Parks System have been lauded as a model for other countries. The rainforests, tropical forests, marine areas and wetlands of Costa Rica are the subject of many university and scientific organization studies. The enrichment of the world's knowledge of these important habitats is an invaluable contribution from the conservation efforts of the various organisations involved.
