Karakteristik Sisa Hutan Alam Di Lingkungan Gambut Pulau Bengkalis

---

Bengkalis Island is one of the islands where 85% of the landscape consists of peatland, originally covered by native peat swamp forests. Over the past five decades, deforestation in this area has led to the near-total loss of this native vegetation. This study aimed to analyze the remaining fragments of peat swamp forest and characterize their ecological features. Field data were collected in two villages within Bengkalis District: Pematang Duku Timur and Kelemantan Barat. In each village, two forest fragments were surveyed, with three 20 × 20 m plots established per fragment (totaling 12 plots).The results showed that tree density in the remaining forest patches ranged from 125 to 230 trees/ha, averaging 188.5 trees/ha. The basal area (BA) of trees ranged from 0.43 to 2.31 m²/ha, with a mean of 1.75 m²/ha, indicating dominance by small-sized trees. Tree species richness varied from 4 to 39 species per location (average: 11 species/location), and the Tree Species Diversity Index (H') ranged from 0.77 to
3.32. Geronggang (Cratoxylum arborescens), a characteristic peat swamp species, was among the most frequently encountered trees. Although all surveyed forest fragments were legally designated as state-managed forest zones, they were de facto under local community control, casting uncertainty on their long-term sustainability.
Key findings: peatswamp forest degradation, forest fragmentation metrics, native species, comunity-state forest conflict, bengkalis island biodiversity
