fluctuations, two seeding windows aze proposed, Mazch 1-May 1 and September 1 to <br />November 15. Seeding at Peschel will occur between September 1 and Mazch 1. <br />Tree and Shrub Planting <br />The approved setback of 100 feet during mining will enable preservation of tree- and <br />shrub-covered areas adjacent to St. Vrain Creek. To promote development of wildlife <br />habitat within the property and to provide additional species diversity, planting of trees <br />in natural groupings azound the reclaimed areas is anticipated. As mature trees cannot <br />be successfully or feasibly replanted, the replacement trees will be smaller in caliper <br />than those currently on site. Tree species to be replanted will include plains <br />cottonwood (Populus sargentii), narrowleaf cottonwood (Populus angustifolia), and <br />peachleaf willow (Salix amygdaloides). In order to establish a more nafive tree <br />overstory and community, the majority of the planted trees will be cottonwood. Trees <br />will be planted in clumps or in association with other woody vegetation to maximize <br />overstory near standing water and to maximize survival through proximity with <br />alluvial groundwater.Tree transplanting is most successful when undertaken during <br />tree dormancy; therefore it is anticipated that all transplanting will occur after leaf fall <br />and dormancy onset in the autumn or before bud-break in spring. <br />To provide a vaned structure and species composition to the revegetated azea, seeding <br />of several woody shrub species is proposed in areas within the reclamation. The shrub <br />species selected are native to Colorado, are found in the general vicinity of the project, <br />and represent species adapted to a wide variety of environmental conditions. These <br />species aze also commonly used in the revegetation of disturbed lands. The species <br />selected are skunkbush sumac (Rhus trilobata), Arkansas rose (Rosa azkansana), <br />western snowberry (Symphoricarpos occidentalis), and rubber rabbitbrush <br />(Chrysothamnus nauseosus <br />Additionally, in selected areas adjacent to ponds or cattail mazshes, coyote willow <br />(Salix exigua) stakes will be planted to encourage development of willow copses. Six <br />to twelve willow stake planting locations aze proposed, with each planting comprising <br />from 50 to 100 willow stakes. <br />6.11 Mulch <br />In order to minimize impacts from wind and water erosion and to protect newly <br />revegetated azeas, a native hay or straw mulch is proposed. Mulch will be applied at a <br />ansnooa <br />
