City of Arvada <br /> Weed Management Plan-Report <br /> Page 3 <br /> ASSESMENT/SITE VISITS <br /> Multiple Site Visits were conducted during 2016 <br /> VMI made multiple site visits most of which to determine application timing, conduct <br /> applications, view results from prior applications, and (per usual) several visits which <br /> were made with the intention of conducting spray efforts but were thwarted due to <br /> high winds. <br /> 2016 TREATMENT DETAILS <br /> Pioneer (North Parcel) <br /> Treatments were conducted on the following dates: <br /> Spring: May 21, May 28 <br /> Summer: June 26, August 7 <br /> Fall: September 11 with one more treatment due this fall <br /> For a total of 158.5 Acres to be treated in 2016 <br /> The following weeds were found and treated: Knapweed, Thistles, Leafy Spurge, Kochia, <br /> Dalmation Toadflax, Tamarisk, Common Mullein and Bindweed. <br /> Refer to Data sheet and/or Map for specific details and infestation areas and densities. <br /> OVERALL COMMENTS/RECOMMENDATIONS <br /> With the prior and still fairly regular soil disturbance caused by equipment traveling <br /> around this parcel it creates prime situations for weeds to thrive. VMI's methodology <br /> has been to first focus on areas along all roadways in an effort to reduce the <br /> potential seed which might be moved inadvertently by tires and the wind created by <br /> motorists. This year in particular heavy infestations of Diffuse Knapweed were <br /> present along with heavy to moderate amounts of Mullein and scattered heavy to <br /> light infestations of Thistles with Kochia & Russian Thistles appearing in mid-late <br /> summer especially along roadways and adjoining areas along with light to moderate <br /> Bindweed. <br /> Several infestations of Tamarisk located primarily in Areas A, B, D & E were located <br /> and treated. <br /> Prairie Dogs are re-infesting Area C along the section of fence which separates the <br /> Pioneer parcel from the Arvada/Blunn Reservoir parcel just inside the gate to the <br /> retail yard E of the Water Tank. It is highly recommended these Prairie Dogs be <br /> controlled as this colony is increasing in size. <br />
