Colowyo, 01981 -019, PR3 adequacy No. 3 1s July 22, 2011 <br />Page 111, paragraph 2 — Colowyo Mine has had shrub establishment success with the direct <br />seeding method; however, some desired plant species that have a high wildlife value did not <br />respond to the direct seeding method in the field trials as reported in the 2008 report by <br />Paschke. Two species in particular Chokecherry (Prunes virginiana) and serviceberry <br />(Amelanchier alnijolia) are present in the Collom expansion area and should be included in the <br />tall shrub vegetation plan as containerized stock. Please include a plan to plant containerized <br />stock in wildlife exclosures that includes these two species. <br />Page 113, last paragraph — Chokecherry and serviceberry (highly desired plant species for <br />wildlife) did not respond to the direct seeding method in the field trials at the Colowyo Mine as <br />reported by Paschke ( "Establishing Shrubs to Achieve Bond Release on Colorado Coal Mines — <br />A Demonstration of Methods ", 2008. CSU, Fort Collins, CO). Please include a plan for <br />containerized stock in wildlife exclosures that includes these two species. <br />( CC prodded a copy of the Colormlo Division of VA'ldhfd. letter Ianxl Mary 17, '01 I, lion[ <br />Vh: Rill de%crgie.Amt AA ddlite Akuwger.

Include the seed mix used and explain the use of species. <br />Also, this paragraph was written in the past tense as if the roads have been cut and stabilized. <br />Please re -write this paragraph in the present or future tense to prevent confusion as to what has <br />been accomplished and what will be performed. <br />This item has been resolved <br />10. Page 111, paragraph 5 — The use of elk proof fencing is to prevent the browsing and destruction <br />of planted shrubs (by large game animals) to ensure their establishment. The Division would <br />like to see a more proactive fencing plan to prevent the destruction of the shrubs rather than a <br />reactive approach after "excessive damage (severe hedging) to those populations is noted." <br />Please submit a comprehensive fencing plan which addresses: location of exclosure (include a <br />map), size of the exclosure and plant community in the exclosure. <br />
