and Management Indicator Species analyses). Existing vegetation at two potential analysis scales <br />(Lease modification area and LAU) is shown in Table 2. Table 3 shows vegetation structural <br />stages within the lease modification area. Acreages within the lease modification area in this <br />analysis (1718.9) are slightly less than in the proposed action provided through the BLM office <br />(172 1) and represent differences in mapping versus information provided from outside the <br />agency. <br />Table 2.
