Shrubs which extended above <br />the plot frame which were less than 4 Feet in height were clipped <br />as part of the plot. Plants were separated by species, clipped, <br />and oven dried for weighing. <br />Results and Range Site Descriptions <br />Site Characteristics <br />Eight range sites were identified on the Energy Mines No. 1 and 2 <br />study as shown in Energy Mines No. 1 and 2 Vegetation (Map 15), and <br />Eckman Park Vegetation (Map 16). <br />A range site is characterized as a plan community displaying a <br />definite floristic composition, physiognomy, and structure. A <br />particular range site may occur across the landscape at a number of <br />• locations all possessing similar envioonmental conditions, i.e., <br />slope, aspect, and soil. It is usually accepted (Cook and Bonham, <br />1977), (Kuchler, 1964, 1968), (Clements, 1916), (Livingston and <br />Shreve, 1921), (Gleason and Cronquist, 1964), that a range site <br />occurring at more than one location will respond similarly to <br />changes in environmental factors such as precipitation, temperature, <br />or air movement. Consequently, vegetation data collected from one <br />location may be extrapolated to the same type of range site occurring <br />at another location in the general vicinity. This is the premise <br />used to establish the "reference areas" described in Section 816.116, <br />Revegetation, Standards of Success. The particular range sites <br />encountered in the mine plan and adjacent areas are described in <br />detail below. <br />Aspcn Range Site <br />Physiographic Features.
