well, so we will be paying close attention to this draw. L. spurge on the west side was a priority during <br /> each and every visit. As mentioned before, L. spurge is prominent in the wash on the west side, as well as <br /> hill sides and on the flats,but one problem area we continue to heavily treat are the berms on both the east <br /> and west slopes. Re-growth on these berms has been heavy, but we have also seen success in controlling <br /> certain areas where the infestations were small. In my most recent application on the berms in July 2016 <br /> and September 2016, our total acres treated were roughly 50-55% less than last year's application. But <br /> with the drought we had from July through September,this#could be deceiving, so we will monitor <br /> closely and observe our results once the growing season resumes in 2017. We have attacked the berms <br /> with our John Deer Gator and the 50' hose reel the past 4 years, as well as individual applicators and <br /> backpack sprayers in an attempt to reach all plants from top to the bottom of the berms. There has also <br /> been a discovery of Diffuse Knapweed(Centaurea diffiusa) on the west side of the property. This is the <br /> first known infestation on the Holcim property and was located roughly .25 miles north of the main cut <br /> running east to west and consisted of roughly 4 plants. All plants were hand pulled to eliminate any <br /> possible seed source and monitored in the fall for potential re-growth. At this time,we did not observe <br /> any re-growth, but again,this can be deceiving with the lack of moisture inhibiting any re-growth. I <br /> highly recommend monitoring and treating accordingly in spring 2017. <br /> The Curtis Lake area was another area that had some heavy infestations in the past and is really <br /> showing good control again this year. This area was treated only 1 time this season in the late spring due <br /> to the control we observed from last years application. L.spurge that was once prominent near the old <br /> pump house and the existing 2 track leading down to it is showing excellent control at this time, and the <br /> same goes for just SE of that location along the base of the reclaimed tailing piles. There was less than a <br /> .5 acre of spurge just east of there,and a few scattered plants in this same area. Our main focus on the <br /> Curtis Lake side was the meadow due west of the lake. 3 years ago this meadow was heavily infested with <br /> L. spurge and this year's follow up showed excellent control. Continued monitoring of this area is a <br /> priority to assure we have eliminated this infestation. The Curtis Lake side of the property has also been a <br /> problem area for the growth of Tamarisk. In the past we have treated the trees with a foliar application, <br /> but have seen re-growth over the past couple of years.As I mentioned 2 years ago, treatment of all the <br /> trees would be costly, so we chose to do a Biological release 2 seasons ago with Diorhabda.Monitoring <br /> of this release took place again this year in late June and we are showing some good results. Trees are <br /> showing defoliation, and our population of Diorhabda has increased, and they are moving around to other <br /> tamarisk in the area. This will be a release site that we monitor for 3-5 more years to assure we are <br /> achieving our goal. The Tamarisk we treated in the past in the Sandstone quarry is showing no signs of re- <br /> sprouts, but we discovered a couple new tamarisk sprouts growing in a couple of the pits along the high <br /> water mark. We walked these pits and performed cut stump treatments in which we treated with Arsenal <br /> (Imazapyr). We will monitor those cuts for any re-growth and treat accordingly. Monitoring of Russian <br /> olive from last year's treatments are showing good results but we had more trees on the west side of the <br /> property on our radar from last year that we never got to. Most of these trees are smaller trees,roughly 3- <br /> 7' tall, and no more than 4"in diameter. These trees were cut and treated this fall, and will continue to <br /> monitor for re-growth. There are several older,more mature trees on the west side that we were unable to <br /> cut and treat due to our funding being exhausted so we recommend removal of those trees next season if <br /> funding allows. All trees were removed via chainsaw and/or loppers, and stumps treated with Makaze <br /> (Glyphosate). Again,monitoring and re-treating will be performed in 2017. <br />
