The Abundance of Odonata Insect in Lebak Swamp, Bukit Baru, Palembang, Indonesia

Abstract

Lebak swamp in Bukit Baru has been lost largely degraded and lost through reclamation activity. Lebak swamp plays important role as land resource in Bukit Baru, Palembang. The study was sonducted to study the composition of Odonata in lebak swamps in Bukit Baru, Palembang, Indonesia. The transect line (1 km) was used to collect odonata in the study area. This study recorded 8 species during the study period. 8 species were found at Site A1, 6 species at site A2, 3 species at site A3, and 6 species at site A4. The highest diversity of odonata was found in site A1, however the other sites have lower odonata diversity. The highest abundance of odonata was recorded at site A2 and A4 and dominated by Ceriagrion coromandelianum and Orthetrum sabina. Neurothemis ramburii had the lowest abund ance at site A1 and A2, but absent at site A3 and A4. The occurrence of odonate species are lower at site around anthropogenic activity suggests the need to protect the lebak swamp so that such uncommon species will not go into local extinction. Neurothemis ramburii can become potential species to evaluate the rate of disturbed environment.

Diversity of Odonata in Langsa Urban Forest, Langsa, Aceh, Indonesia

“…The species number of Odonata species from LUF is higher than Ketambe Forest, Aceh (with only nine species reported) (Wirdjoatmodjo & Atmowidjojo, 1985). Also, this result is higher than the number of species found from other area in Indonesia, such as six species from Watu Gajah Tuban (Sonia, 2022); 8 species from Rawa Lebak Palembang (Teristiandi & Riyanto, 2021); 11 species from Batubolong West Lombok (Zulhariadi, 2022); 12 species from Urban Forest Pontianak (Hartika et al, 2017); 14 species from Tanjung Persada Urban Forest Kalimantan (Soendjoto et al, 2016); and 16 species from the lakes of Universitas Indonesia West Java (Akbar & Basukriadi, 2018). This result was influenced by various factors, including the time of observation, length of observation period, site area, and conditions of the study site.…”
