The study reviews the situation regarding Protected Area extent, legal status and management constraints in each country and territory of East Asia, using a regional review and gap analysis by applying a simple GIS overlay approach. The WDPA has available a near complete GIS cover of PAs in the region and most large PAs are represented by polygons (boundary information). A few large PAs and many very small PAs are represented by circles of correct area around known centre points of the PAs held in the database.
The adequacy of the regional PA system is examined from a variety of viewpoints: altitude, national borders, ecoregions, habitat and important species ranges. The study evaluates only terrestrial and coastal land areas, not marine PA coverage apart to comment on its extent.
