Dampak Abrasi Terhadap Mangrove Di Pantai Desa Api-Api, Kabupaten Bengkalis, Provinsi Riau

---

Bengkalis Regency in Riau Province is one of the areas most affected by abrasion in recent decades. The phenomenon of abrasion has many environmental impacts, including on the remaining mangroves, such as those found in Api-Api Village. This study aims to analyze the existing condition of mangroves affected by abrasion on the coast of this village. In this study, one of the 100 m long beach segments was selected. Data collection was carried out using four transects measuring 100 m x 10 m consisting of 10 plots measuring 10 m x 10 m, which were positioned parallel to each other to form four observation zones from sea to land (zones 1, 2, 3, and 4). The results of measuring the impact of abrasion on land cliffs showed that the retreat of land cliffs that occurred varied greatly, ranging from 2-30 m, with cliff heights ranging from 0-189 cm and cliff cavity depths ranging from 0-283 cm. The results of mangrove condition measurements obtained showed the lowest tree density in zone 1 (average 3.1 trees/plot) and the highest in zone 3 (average 8.8 trees/plot). The number of uprooted or dead trees in zones 1, 2, 3, and 4 were 15 trees/plot, 22 trees/plot, 24 trees/plot, and 9 trees/plot. Based on the existing conditions at the time of the study, it is estimated that trees in zone 1 will be uprooted and lost within the next three months, while trees in zone 2 will experience the same thing in the next three to six months, and so on.

Key findings:: Number of fallen/dead/lost trees, tree density, tree species composition, damage zonation
