چکیده انگلیسی
This research evaluated the status of vegetation cover at right of way locations. Site factors that contributed to low and high ground cover along roadsides and medians were identified. Twenty-nine roadside and median study sites incorporated variability in soil type, elevation, vegetation establishment and cover, seed mixture, slope, aspect, time since planting, and climate. Vegetation cover was measured, and species distribution was identified. Slopes, aspects of the sloping face, and elevations were recorded. Soil samples were tested for nutrients, minerals, texture, and pH. Approximately 50% of the test sites met the 70% cover criteria. Locations of the worst cover (<50%) had soils with high soluble salt content (0.36-1.54 mmhos/cm) or low organic matter values (<1.7%). Vegetation cover was dominated by tall fescue (Festuca arundinacea) and crownvetch (Coronilla varia L.), two species that were included in the current seeding mixture and are considered invasive. To further promote revegetation success and persistence, both maintenance and site specific seed mixtures are needed.
