The Heishan, or Grand Black Mountain of Menglian, is a large expanse of primary mid-montane moist evergreen broad-leaved forest at the border between Lafu Village of Pu ‘er City, Yunnan Province, and Myanmar. Revered as a mountain god by the local Lahu community, it’s home to clouded leopards and lar gibbons, key national protected species. However, it has yet to be included in the country’s official protected area system. In September 2018, as part of our plan to address this issue we conducted a pre-survey on the locality and, through consultation with the community, prepared a survey report.
