Abstract

Sukamade Resort, located within Meru Betiri National Park, is a conservation management area. Dragonflies have significant diversity and extensive spread. The presence of dragonflies in conservation areas is intricately linked to the availability of ecological resources. Conservation areas with robust vegetation surrounding aquatic habitats influence the presence of dragonflies. This study seeks to ascertain the composition of the dragonfly community in Sukamade Resort, Meru Betiri National Park, particularly as foundational data for conservation area management. The study utilized four locations as sampling sites using purposive sampling. Dragonfly sampling was carried out through road sampling using an insect net. Community structure was analyzed using density, diversity (Shannon-Wiener), richness (Margalef), dominance, evenness, and importance value index (IVI), while species–habitat relationships were evaluated using Canonical Correspondence Analysis (CCA). Seventeen species of dragonflies were recognized. Orthetrum sabina and Pseudagrion microcephalum are the species with the greatest population density across all locales. The diversity index indicated a moderate level, the Margalef index demonstrated low requirements, the dominance index was low, and evenness was strong. The significant value index indicates that Neurothemis ramburii, Orthetrum sabina, and Libellago lineata possess the essential value index (IVI 0.38). Canonical correspondence analysis indicates that the taxa Pseudagrion microcephalum, Zyxomma obtusum, Ischnura senegalensis, Diplacodes trivialis, and Trithemis festiva are associated with air humidity characteristics at the Muara besar location. Therefore, it can be concluded that the presence of dragonflies is influenced by habitat factors such as aquatic substrate composition, abiotic parameters (light, temperature, humidity), and riparian vegetation. Protecting riparian habitats and maintaining good water quality are crucial for the conservation of dragonflies, which reflect healthy ecological conditions and support the sustainability of aquatic ecosystems.
