means that United Companies must include in our tamarisk and Russian Olive <br />mana;;ement mine site areas that have been affected any time during the life of the mine <br />but not yet 100% reclaimed. <br />The goal of this part of the plan is to control the tamarisk/Russian Olive density to not <br />excet:d the original density prior to mining and also not to exceed the density on nearby <br />non-disturbed areas, whether it be within the permit boundary or adjacent property and <br />also to meet the approved post mining use. Shown below is an explanation of the <br />company Tamarisk and Russian Olive Management Plan. <br />United Companies will treat tamarisk and Russian Olive as follows: <br />Basal bark treatments will be employed on trees that aze less than 4 inches in diameter <br />with. a 33% mixture of Gazlon 4 +JLB oil as carrier. This treatment will be a dormant <br />treatment undertaken between the months of November and April. Trees over 4 inches in <br />diameter will be controlled through the use of Cut Stump method. These trees will be cut <br />neap: ground level and promptly sprayed with the Gazlon 4 +JLB mixture. The following <br />fall the treated areas will be reassessed. Any re-growth will be treated with Habitat at a <br />rate of 1% with a high quality surfactant. These areas will be assessed on a regulaz basis. <br />Any re-growth will be retreated in the fall of each year. The Habitat treatment will be a <br />foliaz treatment concentrating on the apical ends of the branches. <br />According to Dr. Tim Duncan, University of New Mexico, foremost expert in Tamarisk <br />control, the dormant treatment of Tamarisk in the winter gives roughly 90% control if <br />carried out in the proper fashion and is much more selective in nature than the Habitat or <br />Araenal treatment. Most of the treatment aeeas have native willow and cottonwoods <br />growing next to the Tamarisk and Russian Olive. Strictly foliage treatments will not <br />provide adequate selectivity to retain the existing native species. Russian Olive re- <br />spxouts, if any, will be will be treated with Habitat in the fall when trees are smaller, <br />therefore less over-spray, more selectivity, resulting in zero to minimum damage to <br />desirable undergrowth. <br />Success of this weed program will be monitored a minimum of three times a year, <br />spring, mid summer, and fall. It will probably take several years to successfully control <br />the growth <br />Ir: conclusion, United Companies is committed to control of noxious weeds at all of our <br />locations. Sometimes it's hazder to do knowing your neighbors are not as committed to <br />a~ntrol as you are. United Companies will monitor the success of weed control a <br />minimum of three times a yeaz and follow suggestions from the weed specialist that <br />handles the spraying. I will start showing the areas sprayed -treated on the annual <br />report maps. The annual reports usually mention the existence of our weed program. I <br />v/ill explain in more detail the weed situation and treatments since the last report. <br />Brent W. Ken <br />Resource Manager <br />2 <br />
