Sunday, 20 August 2006, ten folks with naturalist bents ranging to professional biologists, and including botanists, lepidopterists, odistas, birders, herpers, malacologists, and aquarists, gathered to conduct the first of a series of surveys of a 7500-acre Ranch on the headwaters springs of the Frio River in Real County (there was a previous survey done around the turn of the millennium, but this is the first of the current series).

I am in the process of compiling faunal and floral lists for the day, but the number of Odistas and our overall combined interest in the odonate fauna has made it relatively easy to compile our ode list for the day. The numbers appended here are estimates based on my own observations and numbers from Mike Overton (Greg has provided a list of his vouchers; and the photo list is my own and what i know of others’ work) -- our group estimates will be a part of the final report, but these numbers should represent a fair sampling of what we found. -- tg

Other noteworthy species found on the property include: Mournful Duskywing (Overton; vp), Yellow-angled Sulphur (Overton), Ringed Kingfisher (Overton and Heindel; all three kingfishers in fact), Louisiana Waterthrush (Heindel, Gallucci et al.; p), Mexican Tetra (Heindel et al.; p), and Stream Loosestrife (Sander and Dorman; v).
