Reference Area No. 4 and Adjacent Beltline Outslope Areas <br />CONCLUSIONS <br />• Control program objectives appear to have been met. Within the reference area, cover of noxious <br />species was reduced from 41% in 1998 to 2% in 2001. <br />• A satisfactory vegetation cover has been established (47% cover in 2001), dominated by perennial <br />grasses. Forb cover and to a lesser extent shrub cover declined over the course of the control program, <br />but these categories were not major components initially. Over time, nativeforbs and shrubs from <br />adjacent undisturbed habitats would be expected to become established along this narrow disturbance <br />corridor. <br />RECOMMENDATIONS <br />• Suspend formal monitoring unless conditions change. Perform informal visual reconnaissance <br />monitoring late May /early June each year. <br />• Suspend control efforts unless conditions change, or specific problem areas are noted in annual visual <br />inspections. <br />• Document any control efforts. <br />10 <br />
