In using coverage classes which are ground cover percent estimates, as <br />recca~¢cended by Daubenmire (1959), total cover (vegetation plus bare <br />ground plus litter-rock) seldom sums to 1000 due to the fact that ranges <br />of cover classes are estimatesi and only range mid-points are used in the <br />analysis of Grover data. <br />Fre3uency data were derived from the recorded occurrence of each species <br />in the quadrats established in each vegetation type. The maxim~en height <br />of each shrub encountered in the quadrats was recorded in inches with <br />a stick ruler. <br />All cover, frequency and shrub height data were collected during the <br />period August 9 through September 5, 1979. Sample locations are shown <br />on N1ap 1, entitled "vegetation Type Distribution and Sample Site <br />location" (Appendix A). <br />Pdditional shrub height data were collected using a transect technique <br />in mixed brush, upland sagebrush and aspen subtype vegetation types. <br />Besides suppletrenting the shrub height data base, a primary purpose of <br />C• this technique was to evaluate the potential for areas within each of <br />the twv major vegetation types to be incorporated into the topsoil <br />during mining operations. Shrubs greater than 1; inches in diarteter <br />at the base and greater than 5 feet total height are too bulky to be <br />incl~3ed with topsoil stockpiles. Each transect consisted of 10 points <br />placed at 20 m intervals. At each point, the closest representative of <br />each of four different species was selected and its height and <br />circ~anference at the base measured. If four different species were not <br />represented within 10 m of the point, the next closest individual of <br />any species was measured. Ten transects were surveyed in both aspen <br />subtype and mixed brush type and four Caere established in upland <br />sagebrush (D3ap 1, Appendix A). <br />L. -9- <br />
