Abstract

The Patoka River National Wildlife Refuge and Management Area (hereafter Patoka River Refuge or the Refuge) represents one of the largest intact bottomland hardwood forests in southern Indiana, with meandering oxbows, marshes, ponds, managed moist-soil units, and constructed wetlands that provide diverse and suitable habitat for wildlife. Refuge personnel strive to protect, restore, and manage this bottomland hardwood ecosystem and associated habitats for a variety of wildlife. The Patoka River National Wildlife Refuge Comprehensive Conservation Plan (CCP) lists many species of management priority (McCoy 2008), but Odonata are not included, even though they are known to occur on the Refuge. The absence of Odonata from the CCP is the result of lack of information about this ecologically important group of organisms. Therefore, we conducted a survey, from May to October 2009, to document their presence, with special attention being paid to rare, threatened, and endangered species. A total of 43 dragonfly and damselfly species were collected and identified. No threatened or endangered species were found on the Refuge, but three species were found that are considered imperiled in Indiana based on Nature Serve Ranks (Stein 2002). Additionally, 19 new odonate records were documented for Pike County, Indiana. The results of this survey will be used by Refuge personnel to assist in management decisions and to help establish priorities for the Patoka River Refuge activities and land acquisition goals.
