Competition from annual weed, primarily Cheatgrass, needs to be addressed. This appears to <br />be the main limiting factor for establishing successful vegetation at the Refuse Area. Several <br />other topsoil stockpiles indicate that other areas may be susceptible to Cheatgrass invasions as <br />well. While no clear answer is currently available to address this issue several approaches are <br />worth trying. These include: <br />1. Chemical weed control. In the case of Cheatgrass, Oust may provide the needed <br />control to limit annual grass competition in [he first several yeazs of seedling <br />establishment. For best results the soil stockpile should be treated to eliminate the <br />potential seed source. This should allow sufficient time for the seedlings to establish <br />before the weeds can repopulate themselves and the new site. Once the seedlings have <br />become established they are less susceptible to damage from an additional application <br />of Oust if needed. / ~ / / <br />P -L/~ ~J~ (~ ~ ~ 10 fir/ 6N 4K 4 f S4.-SJe. ~ ~~'ryr K~f...c /) ir, <br />Z.E S~-, r T- <br />2.
