Scotch Thistle - This plant shows up in many places. It is a biennial plant and should <br />be controlled in the rosette stage of growth using Milestone or Redeem R&P. Spring <br />treatments will be needed to ensure no seed production.Whether this species is present <br />or not it is important in any integrated management plan to know what to keep an eye <br />out for. <br />Species which are known to exist in the surrounding areas or are upstream in the water <br />shed include Canada thistle, connrion mullien, houndstongue, musk thistle, oxeye daisy, <br />yellow toadflax, myrtle spurge, leafy spurge, spotted knapweed and diffuse knapweed. <br />Permit areas will be monitored for any and all of these species so rapid detection and <br />response can be implemented if found. <br />Tamarisk & Russian Olive <br />Management Plan <br />The Mined. Land Reclamation Board adopted an amendment to their weed policy <br />concerning Tamarisk and Russian Olive on January 19, 2005. The amendment is <br />applicable to areas disturbed by mining operations within the permit boundaries <br />reclaimed after January 19, 2005. Areas in reclamation prior to January 19, 2005 are <br />exempt from Tamarisk-Russian Olive control as far as Division of Reclamation, <br />Mining, & Safety policy is concerned. <br />The goal of this part of the plan. is to control the Tamarisk-Russian Olive density to not <br />exceed the original density prior to mining and also not to exceed the density on near by <br />non-disturbed areas, whether it be within a pen-nit boundary or on adjacent property. <br />There are two treatments that best control Tamarisk. <br />On small plants a branch and foliar leaf surface spray treatment does have limited <br />favorable impact. Spray impacts all it touches. It takes time and effort to avoid <br />spraying desirable growth. Basal Bark treatment can be effective on smaller diameter <br />plants with smooth bark.. It is time consuming to spray the bark surface being careful to <br />avoid spraying desirable growth. Should the spraying be near water the product needs <br />to be non toxic to fish and wildlife, such as Habitat herbicide. Additional herbicide <br />applications may be necessary. We monitor the successs of our weed program a <br />minimum of three times a year, spring, mid summer, and fall. It could take 3 to 4 years <br />to successfully control the growth.
