Review Draft Eastern Gateway Wetland Restoration Site — Annual Report <br /> site before any signs or barriers could be installed (this was in the fall of 1993 <br /> before the hydrology or any vegetation became established). This has not been <br /> a problem recently. <br /> Maintenance Vegetation Control <br /> Activities <br /> 1. Blackberry removal <br /> Youth Corps (Dal) <br /> PW Maintenance <br /> (a) Perimeter Mowing <br /> The perimeter of the site, and area comprising the roadside edges and banks <br /> leading down to the actual wetland, were mowed in May 1994: This mowing <br /> helped to prevent seed production of several species of non - native plants that <br /> occur along the edge of the site. <br /> (b) Interior mowing <br /> A portion of the restored wetland was mowed in July. This was roughly a 1 <br /> acre area in the southeast portion of the site, and includes the area within the <br /> vegetation sample plot #3. The purpose was to restrict seed production of non- <br /> native plants, and to remove competing vegetation that might otherwise be <br /> inhibiting the growth of the tufted hairgrass. <br /> 2. Reed Canary Grass Seedling Removal <br /> In October 1994, a group of volunteers spent an afternoon digging out small <br /> seedlings of reed canary grass that had become established in the restored area, <br /> particularly in the area of emergent meadow habitat. Complete removal of the <br /> seedlings is fairly easy at this stage, as their rhizome systems are not well <br /> developed. Taking such measures on a timely basis is essential to successful <br /> establishment of native plant communities. <br /> • 3. Trail Maintenance <br /> 4. Trash Removal <br /> Page 16 <br />
