Some of these species are characteristic of wet areas xhile others <br />are rarely if ever found in xet areas and are restricted to dry slopes and <br />hilltops. The species diversity is high over the site but, with a few exceptions, <br />are generally characteristic of moderately to highly-disturbed areas usually <br />attributed to overgrazing impacts. <br />COMMUNITY DIFFERENTIATION - <br />As stated in the introduction, eight different communities are present on this <br />site. Most of the area is occupied by a community that occupies the valley plains <br />xhich are relatively level areas generally belox the hills and above the xater <br />courses. Higher areas are occupied by amore xeric community that generally is <br />found on more rocky soils. The xater coisses are occupied by two basic communities <br />of a more mesic form characterized by various species of shrubs and trees; hoxever, <br />there is insufficient differentiation to separate them into distinct map units. <br />On rocky and steep slopes two communities of shrubs are found that are very <br />similar to those found on the xestern slopes of Green Mountain. <br />Three different communities are found on the disturbed sites. On soil and <br />overburden sites are found two communities that are related to the time they have <br />been present and whether the site was originally seeded for stabilization purposes. <br />A fex stockponds and erosion control ponds occur in the xatersheds and they <br />present a different viex from the water courses and the stockpiles although they <br />are apparently related to both vegetationally. <br />Following is a complete discussion of each of these communities and their <br />species composition. These descriptions carefully follow the map units presented <br />on the vegetation map. Other units of very small scale can be found in various <br />locations, but the scale of mapping does not allox displaying these on the map. <br />Furthermore, these small areas are so small they generally are of little <br />importance and are, for the most part, variations on other larger communities <br />included in the following descriptions and shown on the map. <br />Vallev Plain Grassland: This is the largest and most diverse community and it <br />exists over a very large percentage of the affected lands. It is basically a <br />grassland containing local concentrations of small shrubs and subshrubs. It seems <br />to exhibit many variations (stand types) that, on a small scale, could be <br />separate communities but are far too small and localized to map. These stand types <br />will be described Forthwith. <br />39 <br />
