Kajian Stok Karbon Tinggi (SKT) di Areal Hutan Desa Sungai Pelang, Sungai Besar dan Pematang Gadung, Kabupaten Ketapang, Provinsi Kalimantan Barat

Abstract

The Sungai Pelang, Sungai Besar and Pematang Gadung Village Forests (VF) are village forests managed by community groups in the villages of Sungai Pelang, Sungai Besar and Pematang Gadung, South Matan Hilir District, Ketapang Regency, West Kalimantan Province. Community groups managing the Sungai Pelang, Sungai Besar and Pematang Gadung VFs have a strong commitment to sustainable forest management. To minimize the negative impact of forest exploitation on High Carbon Stock (SKT) areas in the area, it is necessary to carry out an inventory of HCS forests, threats, as well as efforts to manage and monitor SKT areas. This research aims to identify High Carbon Stock (HCS) areas in the Sungai Pelang, Sungai Besar and Pematang Gadung VF areas, Ketapang Regency, West Kalimantan Province. Based on the results of the SKT forest inventory, it was found that in the >50 cm diameter class, 1 tree/ha was found including 1 tree/ha in Medium Density Forest (HK2); in the 30-49.9 cm diameter class, 6 trees/ha were found including 4 trees/ha in Medium Density Forest (HK2), 1 tree/ha in Low Density Forest (HK1), and 1 tree/ha in Young Regeneration Forest ( HRM). The distribution of trees in the diameter classes 15-29.9 cm and 5-14.9 cm was found in each land cover class. The highest estimated carbon stocks in the Sungai Pelang, Sungai Besar and Pematang Gadung VF areas were found in the High Density Forest (HK3), Medium Density Forest (HK2), Low Density Forest (HK1), and Young Regeneration Forest (HRM) cover classes at 9,151. 09 tC/ha; while the lowest was in the Plantation-agriculture land cover class (AGRI) at 481.77 tC/ha. Area estimates for vegetation stratification show that the potential SKT class in the Sungai Pelang, Sungai Besar and Pematang Gadung VF areas is 9,151.09 ha, while the non-SKT class in the area is 4,907.85 ha. Based on the results of the FGD and field observations, there are 4 threats to the HCS area in the Sungai Pelang, Sungai Besar and Pematang Gadung VF areas, namely (1) Illegal logging, (2) area encroachment, (3) and (3) Forest and land fires. HCS area management activities in the Sungai Pelang, Sungai Besar and Pematang Gadung VF areas that need to be carried out include boundary marking, internal and external outreach, prevention and protection of HCS areas, as well as coordination with related agencies and the community. Monitoring activities for HCS areas that need to be carried out include carrying out an inventory of HCS forests, preventing and controlling disturbances to HCS areas effectively, and monitoring the intensity of disturbances to HCS areas.
