treatments in this area of the property to assure optimum control. The more north on the east side of <br /> property you go,the cleaner the property looks,with minimal patches of re-growth from existing <br /> infestations already treated, all the way up to the northern boundary of the property adjacent to the large <br /> meadow. One area of concern on the east side that I want to mention are the pits. Each pit with water in <br /> them on the east side of the property has mixed results for control of L. spurge. These pits to date show <br /> only small signs of L.spurge being found in them,but have caused issues in applications in the past due to <br /> the steepness of the pits,and the unstable ground caused by loose rocks and debris. Treatments were <br /> performed in the pits in 2016, and past infestations have decreased,but current observations are still <br /> showing small,random infestations throughout the pits and continue the need to be monitored and treated <br /> accordingly. L.spurge throughout the east side is showing better control as a whole,but there are still <br /> smaller infestations appearing in problem areas near the property line, and require continued monitoring <br /> and treatments as necessary. <br /> The west side of the quarry, running from South to North is where we focused roughly 80% of <br /> our time again this year due to the amount of L.spurge,C.thistle, S.thistle, and Houndstongue, that <br /> showed re-growth, and due to the discovery of new infestations of I.spurge, c.thistle, Bull thistle and, the <br /> increase in growth of an infestation of scotch thistle discovered 3 seasons ago (Onoporduni acanthium),In <br /> 2015 we started observing more D.toadflax on the west side in random patches and I suspect it is due to <br /> the moisture and the seed bank in the soil at these locations from previous years, but we are also noticing <br /> it along the fence line which leads me to believe issues with control are also a direct result of infestations <br /> on adjacent private properties.. These infestations were treated in both the early spring and fall, but will <br /> continue to monitor and treat accordingly. Working from the most southern end of the property on the <br /> west side, all the way to the northern boundary at the meadow had mixed results for past treatments and <br /> new re-growth. Leafy spurge is holding strong in many locations along the west property line in which we <br /> treated heavily in the past, and again this season. But, I feel this will continue to be a problem due to <br /> adjacent properties and their weed issues. We sent letters of recommendation to the property owners to <br /> pressure them into maintaining these noxious weeds in the early spring and had some good responses <br /> from the land owners. We have noticed an awareness of noxious weed control from these landowners and <br /> some management of their lands has started show decent results. Bull thistle and Scotch thistle have <br /> become more of an issue on the west side as well. We discovered these infestations roughly 3 years ago, <br /> and began treating immediately. We believed to have it isolated to the main draw on the west side, but <br /> upon further scouting this year, it has started moving east over the main berm and north. We have located <br /> the main seed source of these infestations coming from heavily infested private properties by the <br /> Boettcher Sandstone Quarry, and have begun the process of sending letters to the surrounding <br /> community. We have noticed some good control on the c.thistle on the west side of the property,but have <br /> also noticed the re-growth of existing infestations in more low lying areas and along adjacent property <br /> fence lines. Most of these infestations are located on the west side of the berms along the wash, and north <br /> of the main ditch that runs through the property. Our crew performed an application of the c.thistle and <br /> treated an existing infestation of scotch thistle that was discovered last year.This infestation last season <br /> was roughly 25-30 small to large size rosettes along with roughly 5-6 plants that were near seeding. We <br /> revisited the location in the early fall and discovered roughly 75% control. We hand pulled any plant that <br /> had matured and set seed and disposed of offsite and performed and application on the S.thistle rosettes. <br /> We will monitor area in spring,but as I mentioned earlier, infestations from adjacent properties will cause <br /> issues with eliminating this weed from the property. This area is a hot spot for C.thistle and L.spurge as <br />
