Areas that qualify for protection under Indonesian law
Year:
2011
Author:
Riccardo Pravettoni, UNEP/GRID-Arendal
Description:
Under Indonesian law, areas that qualify for protection are based on slope (>40%), sensitive soil types, elevation (above 2000m), and peat land (>3m), thereby preventing any man-made development within most of the Sumatran orangutan’s habitat. Certain sensitive soil types, including deep peat, buffer zones along river banks and around other water sources, and the upper reaches of water catchment areas.
