Abstract
Odonata is very sensitive to changes in habitat, making it a reliable bio-indicator of environmental health. This study was conducted to assess the impact of mine tailings on the species diversity of Odonata in Surigao del Sur, Philippines. Eight sampling sites were surveyed comprising four sites with mine tailings and four sites without mine tailings. Opportunistic sampling using sweep nets was conducted on August 24-27, 2013 and October 26- 29, 2013. Eighteen species were documented belonging to sixteen genera and six families. Over-all endemism was low at 22%. Seven species were recorded under sub-order Zygoptera, and eleven under sub-order Anisoptera. Species diversity and evenness were significantly different between areas with mine tailings and those without. Sites without mine tailings had higher abundance, species richness, and endemism than sites with mine tailings. Results indicate that mine tailings adversely affect species diversity of Odonata.
