Area B - 1985, Central Between Two Roads <br /> This area was similar to A in its overall low diversity of species. <br /> However, the total vegetation cover was much lower due mostly to the lack <br /> of warm season grass cover (prairie sandreed was not intercepted) and <br /> reduced cover of alfalfa. Cool season grasses dominated (most notably <br /> smooth brome (Bromus inermis) and crested wheatgrass, while alfalfa <br /> remained an important contributor to overall cover. <br /> Area C - 1986, West of Road <br /> This stand is very diverse (13 total species in sample data) and is <br /> dominated by warm season grasses (46.5% relative cover). Dominant <br /> individual species include switchgrass (Panicum virgatum) and russian <br /> thistle with intermediate levels (3-5% absolute cover) of prairie <br /> sandreed, crested wheatgrass, western wheatgrass (Agropyron smithii ), <br /> slender wheatgrass (Agropyron trachycaulum) and prairie sunflower. No <br /> perennial forb species were sampled. <br /> Area D - 1986, Central Between Two Roads <br /> This area is also relatively diverse (11 total species) and again is <br /> dominated by warm season grasses (57.9% relative cover) , though russian <br /> thistle is the dominant individual species. Prairie sandreed and sand <br /> bluestem (Andropogon hallii ) are the most important grasses, with blue <br /> grama (Boutelova gracilis) and western wheatgrass present in intermediate <br /> amounts. Again no perennial forb species were present. <br /> Area E - 1986, East of Road <br /> Fourteen species were sampled. Warm season grasses heavily dominated <br /> (73.2% relative cover) . Blue grama, prairie bluestem, and prairie <br /> sandreed were dominant species. Russian thistle was present in small <br /> amounts and was the only annual species sampled. Alfalfa was also <br /> present, though in small amounts. <br /> Area F - 1987, West of Road <br /> The diversity of warm and cool season grasses is low, though warm species <br /> grasses (blue grama, prairie sandreed, and sand dropseed (Sporobolus <br /> cryptandrus) ) did account for 34.4% relative cover. However, the stand <br /> is heavily dominated by russian thistle (51 .5% relative cover) . Cool <br /> season grasses accounted for only 6% of the total plant cover. <br /> Area G - 1987, Central Between Two Roads <br /> This area has the same warm season species as Area F; however, these <br /> species contribute much less absolute and relative cover. Russian <br /> thistle accounts for 84.0% of the total plant cover. Cool season grasses <br /> contribute 2.5% total relative cover. <br />
