One major land-use development in the Gunung Tarak Landscape (GTL) in West Kalimantan Province, Indonesia has been the expansion of oil-palm plantations since the early 2000s, at the expense of forest and secondary regrowth areas.
The areas of High Conservation Value (HCV) identified at the landscape scale in GTL show a substantial decline between 2000 and 2016, with the relatively stable areas being only in official Protected Areas and Protection Forests; some of the losses resulted in ecological disconnection.
Identified HCV areas in GTL are a useful reference for further conservation planning, including the establishment of ecological corridors at a landscape scale and also for more detailed HCV identification in OPMUs.
