Mangrove Conservation

Mangrove ecosystems at the estuary of Teleng River, Pacitan Bay, call for preservation, protection, and development as a natural vegetative defense against tsunami impacts. Limited availability of potential land for mangrove growth poses a challenge to sustainable mangrove management. To anticipate land acquisition for another use, it is necessary to study land suitability for mangrove and mangrove conservation priorities in the Pacitan Bay. The land suitability parameters consisted of landform, slope, soil texture, and tidal fluctuation, while the mangrove conservation priority was determined based on several aspects: mangrove land cover reduction, mangrove damage level, beach ridge and riparian zone, and land suitability. The results indicate that lands with high potential for mangroves are distributed along Teleng and Grindulu Rivers but not precisely at the estuary. Based on the suitability results, highly potential and potential lands are proposed for mangrove planting, while existing mangroves are for protection and preservation zones, especially on the sides where relatively young mangroves grow for their roots are not strong enough to withstand river currents.

The utilization of the coastal environment is still dominated by-products and has not yet switched to ecosystem service products, such as the use of mangrove ecosystems as ecotourism. This study aims to assess the local community's perception of the potential diversity that becomes an object for the community's economy. The research method uses surveys, observations, and interviews for social data, while the ecological data use transect and quadratic methods. Furthermore, data analysis used descriptive statistics. In addition, ecological data were analyzed using density (Ki), relative frequency (FR), diversity (H') of mangroves, and ecological indexes (Diversity (H'), Evenness (E), Dominance (D)). The results of the study found six mangrove species, ten echinoderm species, and thirteen bivalves. The highest diversity index (H') was in Poton Bako 1.80 and the Evenness index ranged from 0.80 – 0.98 with a stable category. Biota relative dominance the association index of echinoderms is high 0.79–0.11. Meanwhile, the bivalves Dominance index of 0.03-0.11 was low. In addition, local community's perception of mangrove conservation for ecotourism, 63% of the community stated, 7% is not possible and 30% is not. The feasible value of mangrove development is 62%, 17% is not feasible and 21% does not know. The priority developed by Eduwisata is 48%, Bird Watching is 20% and Tracking is 32%. The conclusion is that the choice of using mangrove ecosystem services can be developed as a policy in overcoming economic threats and the vulnerability of marine biota as well as solutions for local communities.
