Gastropod Community Structure in the Mangrove Ecosystem of Sukadana West Kalimantan
West Kalimantan is home to extensive mangrove ecosystems, which are widely distributed along its coastal regions, including the Sukadana Subdistrict. These ecosystems play crucial roles in coastal environments, one of which is providing habitat for a variety of aquatic organisms, including gastropods. However, the mangrove ecosystems in this area face significant challenges, particularly deforestation due to land conversion for agricultural activities. Increasing human activities continue to exert considerable pressure on these habitats. This study analyzed gastropod diversity and community structure in the mangrove ecotourism area of Sukadana, North Kayong Regency, West Kalimantan. Field sampling was conducted in September 2024 using a 10 × 10 m² transect quadrat. Within each transect, five 1 × 1 m² subplots were established—one at each corner and one in the center. A total of 12 species from 9 genera and 7 families were identified, with Pirenella alata and Chicoreus capucinus being the most dominant, contributing 33.05 and 30.63% of the total individuals, respectively. The Littorinidae family exhibited the highest species richness. Species were categorized by habitat preference: arboreal (50%), epifaunal (25%), and both arboreal and epifaunal (25%). Diversity indices (H′) indicated low to moderate diversity, with values ranging from 1.06 to 1.84, while evenness (E) ranged from 0.59 to 0.97. The highest dominance value (C= 0.42) was recorded at station 5, indicating an uneven species distribution. These findings highlight the ecological importance of the Sukadana mangroves in supporting gastropod diversity and emphasize the need for targeted conservation efforts to safeguard these valuable ecosystems.
