Author Location ? Dye Creek Preserve
Location Narrative ? The stand is located within the TNC Dye Creek Preserve, in the NE corner of the parcel. The plot is about equidistant between Lost Wallet Road and the power lines SE of the North Main Road. The stand and the plot face SE on a 20 degree slope below the ridge top. At this point in the season Calycadenia, Centaurium, and Navarretia dominate the cover, while other herbs are standing dead or otherwise difficult to identify. Bedrock and large rocks occur with Selaginella and moss on the ground surface.
