Remote Detection Of Disturbance From Motorized Vehicle Use In Appalachian Wetlands, Walter Smith
Remote Detection Of Disturbance From Motorized Vehicle Use In Appalachian Wetlands, Walter Smith
Virginia Journal of Science
Wetland disturbance from motorized vehicle use is a growing concern across the Appalachian coalfields of southwestern Virginia and portions of adjacent states, particularly as both extractive industries and outdoor recreation development expand in regional communities. However, few attempts have been made in this region or elsewhere to adapt approaches that can assist researchers and land managers in remotely identifying and monitoring wetland habitats disturbed by motorized vehicle use. A comparative analysis of wetlands impacted and unimpacted by off-road vehicle activity at a public recreation area in Tazewell County, Virginia was conducted to determine if and how a common, satellite-derived index …

Oviposition Sites And Emergence Habitats Of 13-Year Periodical Cicadas (Brood Xix) In Eastern Virginia, Heather F. Sahli, Stewart Ware
Virginia Journal of Science
While much research has been done on periodical cicadas, apparently no quantitative studies have been carried out to determine the vegetational structure of periodical cicada brood emergence sites or oviposition sites. We determined large tree and small tree densities and dominance in five forest stands which experienced high densities of Brood XIX cicada emergence in 1998. Paired observations were made at one of these sites to determine whether there was a preference for egg deposition in woodland edges versus the forest interior. A list was compiled of all the tree species which exhibited evidence of egg deposition. We found that …
