The reclamation seed mixture was provided by the Natural Resources Conservation Service for
<br /> mine land reclamation in the region of the proposed permit area and is listed below.
<br /> Revegetation Seed Mix
<br /> Species Rate
<br /> (lbs PLS/acre)
<br /> Wheatgrass, Western 4.80
<br /> Grama, Sideoats 1.82
<br /> Grama, Blue 0.50
<br /> Green needlegrass 1.92
<br /> Buffalograss (bur) 1.65
<br /> TOTAL 10.69
<br /> Rates are for drill seeding. If broadcast seeding is used, double
<br /> seeding rates.
<br /> If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before
<br /> they can go to seed. The areas will be mowed periodically for additional control as needed.
<br /> Mechanical control will be used as a first priority. Chemical methods will only be used if no
<br /> other alternative produces acceptable results.
<br /> Periodic inspection for noxious weeds, at least once a year early in the season, will be done. The
<br /> weed inspection will search for not only the expected species but also any new List A or B
<br /> species introductions. It is likely that non-noxious and List C species will also be found. Non-
<br /> noxious weeds, which are often native invaders, do not need to be controlled, but if the
<br /> population of a List C species is controllable then it will be included in the control program.
<br /> List C noxious species are problematic but are usually not as serious as List B species. List B
<br /> species in Colorado and utilized for Weld County weed management include: Absinth
<br /> wormwood, Black henbane, Bouncingbet, Bull thistle, Canada thistle, Chinese clematis,
<br /> Common tansy, Common teasel, Corn chamomile, Cutleaf teasel, Dalmatian toadflax, Dame's
<br /> rocket, Diffuse knapweed, Eurasian watermilfoil, Hoary cress, Houndstongue, Jointed goatgrass,
<br /> Leafy spurge, Mayweed chamomile, Moth mullein, Musk thistle, Oxeye daisy, Perennial
<br /> pepperweed, Plumeless thistle, Quackgrass, Russian knapweed, Russian-olive, Salt cedar,
<br /> Scentless chamomile, Scotch thistle, Spotted knapweed, Spurred anoda, Sulfur cinquefoil,
<br /> Venice mallow, Wild caraway, Yellow nutsedge, and Yellow toadflax.
<br /> All List A species must be eradicated by law. These weeds include African rue, Bohemian
<br /> knotweed, Camelthorn, Common crupina, Cypress spurge, Dyer's woad, Elongated mustard,
<br /> Giant knotweed, Giant salvinia, Hydrilla, Japanese knotweed, meadow knapweed, Mediterranean
<br /> sage, Medusahead, Myrtle spurge, Orange hawkweed, Purple loosestrife, Rush skeletonweed,
<br /> Squarrose knapweed, Tansy ragwort, and Yellow starthistle. The current complete list of
<br /> noxious weed species and local management plans is available from the Weld County Weed
