| Abstract/Contents: | "A plant community assessment on Virginia roadways was conducted to indicate the most common native plants that colonize roadsides and available information that may support their suitability for roadside vegetation establishment. At 490 sites, we identified 67,330 plants comprising 616 unique species. The Shannon Diversity Index was calculated for 2,450 10-m transects, and indicated that plant biodiversity was higher on low-maintenance distal backslopes compared to high-maintenance road edges, shoulders, and ditches. Plant biodiversity was also higher on secondary roads compared to primary roads. The unique introduced species encountered were relatively stable across Virginias seven ecoregions, but unique native species were more ecosystem dependent. Unique native species increased from about 114 species on the road edge and shoulder to 281 species on the distal backslope. Likewise, the likelihood of encountering a native plant increases from 1 in 4 on the road edge to 1 in 2 on the distal backslope. Among native plants that were most frequently encountered, seed for most were either unavailable or price prohibitive. Festuca rubura was the most frequently observed native grass. Although native to North America, much of the commercial varieties for this species were probably introduced from Europe. Andropogon virginicus, Tridens flavus, Dichanthelium clandestinum, Tripsacum dactyloides, and Sorghastrum nutans have desirable attributes as native roadside grasses and are among the top 20 most commonly encountered native grasses on Virginia roadsides. All but A. virginicus could be seeded with conventional spreaders or drills. The average cost of seed for these grasses was $59 per pound compared to $2.40 per pound for tall fescue. Among grasses that are currently not commercially available, Setaria parviflora, Eragrostis pectinacean, Dichanthelium laxiflorum, and Panicum anceps were among the top ten most commonly encountered native grasses and have characteristics that would be desirable for roadside vegetation." |
