Abstract

Swamp is a unique wetland ecosystem with waterlogged conditions, overgrown with distinctive vegetation types. Swamp ecosystem in University of Lampung are freshwater swamps that are well watered throughout the year and overgrown with aquatic vegetation, making it ideal for the habitat of various types of dragonflies (Odonata). The life cycle of the dragonfly is in two environments, pre-adult phase is aquatic and adult life around the waters, so the dragonflies can be used as an environmental bioindicator. The study aims to find the species of dragonflies with conservation status and trading status, analyzing the relative abundance and diversity of dragonflies founded in the swamp ecosystem at the University of Lampung. This research conducted with exploration method or (field to field) in three locations (R1, R2, R3), the random exploration was done two times at morning and afternoon. The results showed that 12 species of dragonflies from 3 families ecountered during study. The highest abundance of dragonfly speciesis Orthetrum sabina with 20.14% and the smallest was Acisoma panorpoides and Zyxomma obtusum with 2.16%. Conservation status of the 12 species are Least Concern (IUCN), unprotected (UU / PP) and non-appendix (CITES). The value of diversity index shows a moderate scale with 2.26, which means the condition of swamp ecosystem in University of Lampung still has good productivity as a habitat to support the life of dragonfly.
