Wadge Pasture 50 <br />Wadge Pasture Comparison 50 <br />Mountain Brush Reference Area 15 <br />Sagebrush Reference Area 15 <br />Native Study Area 20 <br />All shrubs, including seedlings, with root crowns found within the quadrat boundaries were <br />tabulated by species and by life stages as follows: seedling, mature, or dead. <br />Plant Species Freauencv and Density Measurements <br />During the course of cover and shrub density sampling, all plant species occurring within one <br />meter of the 50m cover sample transect were noted as a part of each sample. Frequency for <br />each plant species observed during sampling was calculated by dividing the number of sample <br />i transects in which the species was observed by the total number of samples (see cover sample <br />distrtibution by area above). As such, this value is more probably correctly known as <br />' "constancy." <br />The total number of species (within each lifeform) observed in each sample provide a measure • <br />of "species density", indicating relative species richness of different ;areas. These measures <br />provide an indication of progress toward return of diverse species cornpositign to the reclaimed <br />areas from a different perspective than is available from examination .if cover data alone. <br />Plant Species Listing <br />During the course of the field work, a list of all encountered plant sF~ecies (quantitatively plus <br />incidental observations) was compiled for each reclamation area and the two reference areas <br />plus the Native Study Area. Scientific names used follow Weber and Johnston (1979); <br />common names cited may be found in Beetle (1970), Nickerson et al. (19761, or SCS (19791. <br />Cross reference to the substantially revised scientific nomenclature for the flora of Western <br />Colorado, as set forth by Weber (19871, may be determined by reference to Wittman et al. <br />(1988). Of plant species observed, only Canada thistle (Cirsium arvense), Dalmation toadflax <br />(Linaria dalmaticah and common bindweed IConvolvulus arvensis) are listed state-wide as <br />noxious weeds (Thornton et al. 1974). Blue lettuce ILactuca oulchellal, buckhorn plantain <br />(Plantago lanceolatal, curly dock (Rumex crisousl, and pennycress (Thlasoi arvensel, all <br />' restricted noxious weeds in Colorado (Thornton et al, 1974) are also sparingly present at some <br />locations in the reclaimed areas. <br />• <br />4 <br />
