Keanekaragaman Hayati Tumbuhan Di Areal PBPH PT. Wana Hijau Pesaguan Kabupaten Ketapang, Provinsi Kalimantan Barat

Abstract

PT. Wana Hijau Pesaguan (PT. WHP) is a company operating in the field of industrial forest plantations in Ketapang Regency, West Kalimantan Province. The company has a strong commitment to sustainable forest management. To minimize the negative impact of forest exploitation on plant biodiversity in the area, it is necessary to identify the existence of protected and/or rare plant species, their threats, as well as efforts to manage and monitor biodiversity that need to be carried out. This research aims to identify habitat conditions and plant biodiversity in the PBPH area of PT. WHP, Ketapang Regency, West Kalimantan Province. In the PBPH area of PT. WHP consists of 440 species which can be grouped into 98 families, where the highest plant species richness is found in secondary dryland forests (381 species) and the least is found in shrubs (24 species). Based on its protection status, in the PBPH area of PT. WHP did not find any protected plant species according to Minister of Environment and Forestry Regulation (Permen LHK) No. P.106 of 2018; However, 5 types of endemic plants were found; found 3 types of plants included in the CITES Appendix II List; and found 12 (twelve) types of plants which are classified as VU/Vulnerable according to IUCN, 1 (one) type which is classified as EN/Endangered according to IUCN, and 4 (two) types of plants which are included in the CR category /Critically Endangered according to IUCN. There are 4 threats to plant biodiversity in the PBPH area of PT. WHP are (1) Illegal logging, (2) Area encroachment, (3) Availability of resources to manage and monitor plants is still lacking, and (4) Forest and land fires. Plant biodiversity management activities in the PBPH area of PT. WHP needs to do are boundary marking, internal and external outreach, prevention and protection of plant biodiversity, further surveys of plant species population status, and coordination with related agencies and the community. Plant biodiversity monitoring activities in the PBPH area of PT. WHP that needs to be carried out are plant diversity and density, the effectiveness of preventing and controlling disturbances to plant biodiversity, as well as monitoring the intensity of disturbances to plant biodiversity.
