Descripción
West Kalimantan has a high diversity of biodiversity. In Betung Kerihun National Park, at least 1,216 flora species are identified, 75 species of them are endemic to Kalimantan. The area also has at least 48 mammal species, including orangutan and honey bear. Conserving this biodiversity is important to sustain the ecological function. The Assisted Natural Regeneration, introduced by the Forest Investment Program-1 with the objective to provide alternative methodology for conserving biodiversity, improve natural wilding growth, and support in sustainin genetic resources. Vegetation analyses were conducted in several transects representing different forest habitat in West Kalimantan. Both flora and fauna were recorded and analyze on their protection status, abundance, and diversity. A 2,000 Ha within the Danau Sentarum National park area was targeted for the ANR program. Flora/fauna plots were distributed at the peat forest in Pulau Majang Village. At the seedling stage, 5 species were identified. Dichilante borneensis dominated the seedling stage. At the tree stage, a species of Shorea balangaran dominates the strata with more than 1,000 individuals per Ha. Mother trees of Shorea balangaran and Gonystylus bancanus were also identified and marked for future seeds collection. During the forest patrol in the period of September 2020, seedlings were checked and any disturbance (grasses, climbers, tree falls) were removed. ANR focused on liberating seedlings and poles from these disturbances. Additionally, observation on fauna were conducted. Mammal species, reptile, and bird species were identified, in which all of them are protected (CITES I & II and according to the Indonesian regulation).
