2019 Keeling Pit Noxious Weed Management Plan <br /> By the Huerfano County Noxious Weed Department <br /> mix provided in the original Reclamation Permit. Doing so will prevent further <br /> site\topsoil erosion. Reseeding will need to comply with the specific herbicide product <br /> label recommendations related to grass establishment intervals by species. When using <br /> a broadcast method of reseeding, it is recommended to use twice the PLS rate as <br /> indicated for seed drilling in the original Reclamation Permit. <br /> E. MANGEMENT GOALS <br /> The overall management goal of this plan is to stop the further introduction of viable seeds <br /> and noxious plant species capable of regeneration within the site so as to comply with the <br /> Division of Reclamation, Mining, and Safety standards.The establishment of a resilient and <br /> competitive native\desirable plant community will be necessary to ensure the long term <br /> success of invasive plant exclusion. <br /> F. TIMELINE FOR COMPLETION <br /> A minimum of four years will be required to eradicate the species of greatest concern <br /> (hoary cress, leafy spurge) within the mine site given the widespread distribution of both <br /> species and the large amount of viable seed within the soil seed reserve. The other C list <br /> species found on site will not be subject to eradication being that it is not a realistic <br /> outcome given their widespread distribution throughout the surrounding area. The <br /> ultimate management goal for these C list species will be containment and suppression. <br /> Future weather conditions will greatly dictate the duration and success of needed <br /> treatments. Seasons of exceptionally high precipitation such as this year(2019)will greatly <br /> aid in the depletion of viable seed being that germination rates are higher,while an <br /> exceptional drought year like 2018 will provide an overall setback as these species are <br /> dormant and seedling depletion through germination is limited at best. <br /> G. MEASURABLE OBJECTIVES <br /> 1. The overall reduction in infested acres of hoary cress. <br /> 2. The overall reduction in infested acres of leafy spurge. <br /> 3. The overall reduction in infested acres of C list species. <br /> 4. The creation and promotion of a resilient plant community capable of self-regeneration <br /> that creates exclusion of undesirable noxious weed colonies. <br /> 5. The control\elimination of additional noxious weed species. <br />
