In Borneo, ‘Forest’ are areas that area mainly composed of closed-canopy (>90% cover) evergreen Dipterocarps. In some highland regions, ‘Forest’ may also include Kerangas and in coastal areas, mangroves. ‘Intact Forest‘ include pristine old-growth forests, i.e. forests that have never been disturbed by humans, or for which disturbances were too localized to be detected by satellites. ‘Logged Forest‘ are areas of old-growth forest that have been impacted by industrial-scale mechanized selective logging at some point since 1973. They have lost their original structure, but have remained in good condition and regenerate quickly. ‘Regrowth Forest’ are areas of forest that were likely young regrowth in 1973 and resemble old-growth forest in 2015. In 1973, before extractive industries began, forests were mainly Intact (old-growth). ‘Forest’ excludes young forest regrowth, scrublands, tree plantations, agricultural land, and non-vegetated areas. The latter are clumped into ‘Non-Forest’. Method: To map 1973 forest area we analyzed 61 LANDSAT MSS satellite images acquired during the 1970s and spanning the whole Borneo.
