| Abstract/Contents: | "Vegetation management practices that maintain or enhance the integrity of native plant communities are desirable. Recently, extensive botanical surveys conducted within powerline rights-of-way in Kentucky have discovered numerous native plant communities within these corridors. Many of these communities are havens for sensitive and rare plant species. New populations of orange crested orchid, yellow fringed orchid, spreading pogonia, little ladies' trees, and rattlesnake master were discovered. This study was developed to add insight into how utilities may better manage their powerline corridors to protect these communities of sensitive and rare plant species. Five powerline corridors were selected for this study to observe the response of the plant communities to the three vegetation management practices: mowing, prescribed burning, and herbicide treatment. The experiment was conducted as a randomized complete block design with three replications of each treatment with a plot size of 15 m by 30 m. Three 10 m permanent line transects were established within each plot, and species data were recorded at 1 m intervals within each transect in late August or early September of 1998 and 1999. The surveys were conducted in 1998 to establish the existing components of these communities. Treatments were initiated after the 1998 growing season. The mowing treatment was conducted in November and September of 1998, while prescribed burning was conducted in February or March of 1999. The herbicide treatment consisted of a broadcast application at 20 GPA of an imazapyr/glyphosate (0.5%/2% v/v) tank mixture with a non-ionic surfactant (0.5% v/v) implemented in May 1999. Square root transformations of the species per plot and total plants per plot data were analyzed with the general linear model procedure and fisher's protected LSD. In 1998 there were no significant differences in species numbers or plant numbers before treatment initiation. A significant descrease in species numbers and plant numbers were detected in the herbicide treatment of 1999. No statistical differences for species per plot or total plants per plot were detected within the mowing and burning treatments for 1999." |
