Weed Contro! <br />This area of La Plata County is known to have some weeds of concern such as the thistle group <br />and knapweed. Four Comers Materials will take extreme caze in preventing weeds from establish- <br />ing infestations in the permit area by doing the following: <br />1) Bach mid-April, a noxious weed survey will be made ofthe permit area. <br />2) If any noxious weed patches or plants have been identified, they will be sprayed by backpack <br />sprayer or ~}-wheeler using chemicals approved for use by the Weed Management Commission of <br />La Plata County. This will be done within 2 weeks after the inspection when the weeds are most <br />vuhierable. Care will be taken to spot spray where possible to avoid killing desirable broadleaf <br />plants. <br />3) After reclamation of portions of the site and after Yinal reclamation, weed surveys and spraying <br />will continue until the perennial cover and production of the site have met DMG requirements and <br />bond release has been obtained. <br />"1'he llivision and Weed Management Group of L,a Plata County will be consulted regarding any <br />weed infestation azea and any control measures prior to their initiation. The plan does not contem- <br />plate total weed removal on the property, especially the removal of some non-noxious weeds. Past <br />experience shows that some initial weed cover in the first year following retopsoiling is beneficial <br />to the reclamation effort in dry range sites. Weeds tend to provide shade for new grasses, aze a <br />means of holding snow on the seedbed longer and protect it from wind and water erosion urriil the <br />planted species gradually take over the site. <br />Cugnini 12/03 24 <br />
