Without drought and irrigation,the grass cover should be close to baseline <br /> coverage in 5 years. <br /> Weed control: The berm shall be maintained in compliance with the Chaffee County <br /> Noxious Weed Management Plan and Colorado Noxious Weed Act. Annual weeds, Kochia (Bassia <br /> scoparia), Russian Thistle (Salsola spp) Tumblemustard (Sisymbrium altissimum) and Cheatgrass <br /> (Bromus tectorum) should be mowed right before seed set to reduce spread or controlled with herbicides <br /> early in the growing season. Kochia and cheatgrass should be controlled to prevent takeover of the site. <br /> Weed growth is to be expected during the first year and should be monitored. There will be native weeds <br /> that do not present long term problems and should be allowed to grow and replenish their seed banks. All <br /> noxious weeds as well as the above annual weeds should be controlled through mowing and/or herbicides <br /> and affected areas replanted afterwards. Weeds will always exist on site since wind deposited seed <br /> cannot be prevented, however, weed cover should not exceed 15% of total plant cover after the <br /> establishment period. <br /> Milestones: A baseline vegetative cover assessment should be done before topsoil removal to <br /> determine the naturally occurring cover. Vegetative cover should be within 5-10% of the baseline cover <br /> by year 5. Vegetative cover in years 1-4 will depend on precipitation. Monitoring the vegetation should <br /> occur at least twice a growing season so that problems can be addressed in a timely manner. <br /> Permanent Revegetation: <br /> Native topsoil from the berms will be applied over all disturbed areas at a depth of 6-12". All <br /> slopes will be established with a maximum steepness of 31-1:1 V final grade. Once finish grade has been <br /> established, tilling of chiseling will occur to loosen the soil surface. Drill seeding will be used to apply <br /> the seed. After seeding,soil conditioning may be used, such as straw mulch. <br /> The current use of the property is agricultural grazing land. To return the area to previous <br /> conditions,all disturbed areas should be reseeded with a permanent seed mix. Based on observations of <br /> the existing plant cover, I would recommend the following mix for the reclaimed areas: <br /> Permanent Seed Mix <br /> • 40%Blue Grama(Bouteloua gracilis),variety Alma, Bad River or a local ecotype <br /> • 15%Sleepygrass(Achnatherum robustum)or if unavailable Green Needlegrass(Nassella <br /> viridula)Cucharas or Lodorm <br /> • 15%Needle and Thread grass(Hesperostipa comata) <br /> • 10%Rocky Mountain Beeplant(Cleome serrulata) <br /> • 5%Narrowleaf Yucca(Yucca glauca) <br /> ACA Products, Inc•702 Gregg Drive; PO Box 1887.
