LARIMER <br />COUNTY <br />),VrhII11.) 1 1 X(FIIFNJl <br />Mike Toelle <br />Senior Mining & Raw Materials Specialist - MPC <br />3500 Highway 120 <br />Florence, CO 81226 <br />Hi Mike, <br />DEPARTMENT OF NATURAL RESOURCES <br />• Parks & Visitor Services • Open Lands Program • Weed Management & Forestry <br />1800 South County Road 31 <br />Loveland, CO 80537 <br />(970) 679 -4570/ (970) 679 -4574 FAX <br />www.larimer.org /naturalresources <br />March 23, 2012 <br />It looks like spring is coming early this year and I would like to propose a continuation of the weed work we've <br />been conducting at the Boettcher Limestone Quarry, the Dilts Quarry, the Boettcher Sandstone Quarry, and <br />areas adjacent to Curtis Lake. The Larimer County Weed crew has made great progress in managing noxious <br />weeds but there are still infestations of deep- rooted perennial species such as leafy spurge and Canada thistle <br />that are never completely controlled in 1 -2 seasons. With sufficient funding the crew could again survey and <br />spray as necessary the entire property in approximately 2 weeks time. Most of the work would be conducted <br />this spring, with a final sweep in the fall of 2012. <br />The Larimer County Weed District charges $80.00 per hour for an ATV sprayer. We propose 2 ATV <br />applicators surveying and spraying weed infestations systematically across the 850 acres of the Boettcher <br />Limestone quarry. Such a project would take 10 -12 days to complete due to the uneven terrain and the <br />potential for more unforeseen weed infestations. Estimated acres actually treated -15% or about 125 acres. <br />• Two sprayers x 6 hours per day (no charge for travel time to and from quarry) = glirday <br />• Prescribed treatment of /acre x approx. 10 acres /day = <br />• Labor + herbicide cost = - /day <br />• x 8 -12 days, spring 2012 = - <br />• 'i /day x 2 -3 days, fall 2012 = 11.110 - wish <br />We would continue to use Perspective herbicide, which has been very effective for control of leafy spurge and <br />Canada thistle. If this proposal is accepted we would start at green -up this spring, surveying and spraying leafy <br />spurge, Canada thistle and possibly tamarisk along some of the water -ways. Please contact me or Bobby <br />Goeman @ 970 - 222 -5339, for information or more detailed explanation of this proposal. I look forward to <br />working with you again in 2010/2011. <br />Tim D'Amato <br />Land Stewardship Manager <br />Larimer County Department of Natural Resources <br />PO Box 1190 <br />Ft.
