Natural Resources Conservation Service seed mixture recommendations for lands in the region
<br /> of the proposed permit area are listed below.
<br /> Revegetation Seed Mix
<br /> Species Rate
<br /> (lbs PLS/acre)
<br /> Wheatgrass,Western 4.00
<br /> Grama, Sideoats 2.70
<br /> Grama, Blue 0.45
<br /> Green needlegrass 2.00
<br /> Switchgrass 0.40
<br /> TOTAL 9.55
<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 Larimer County weed management include, but may not be
<br /> limited to: Absinth wormwood, Black henbane, Bouncingbet, Bull thistle, Canada thistle,
<br /> Chinese clematis, Common tansy, Common teasel, 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, Russian knapweed, Russian-olive, Salt cedar, Scentless
<br /> chamomile, Scotch thistle, Spotted knapweed, Sulfur cinquefoil, Wild caraway, Yellow
<br /> 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 /> Flowering rush, Giant knotweed, Giant reed, Giant salvinia, Hariy willow-herb, Hydrilla,
<br /> Japanese knotweed, Meadow knapweed, Mediterranean sage, Medusahead, Myrtle spurge,
<br /> Orange hawkweed, Parrotfeather, Purple loosestrife, Rush skeletonweed, Squarrose knapweed,
<br /> Tansy ragwort, Yellow starthistle, and Yellow flag iris. The current complete list of noxious
<br /> weed species and local management plans is available from the Larimer County Weed Division.
