6.10 Revegetation <br />The focus and goal of revegetation at the site will be the establishment of effective <br />vegetation cover in the area that will provide a transition azea from the hydric area <br />along the St. Vrain River and ponds to the more mesic upland areas to the south. To <br />this end, replacement of vegetation will focus on placement and establishment of <br />scattered shrub clumps, trees, and a vigorous herbaceous community. <br />Seed Mixture and Seeding Rate <br />Herbaceous revegetation of the reclaimed azea is proposed to minimize impacts to the <br />physical environment by reducing wind and surface water erosion, and impacts to the <br />biologic community by providing wildlife habitat, food and shelter in the immediate <br />area. Currently, the area is dominated by inland saltgrass (Distichlis stricta), western <br />wheatgrass (Agropyron smithii), cheatgrass (Bromus tectorum), and weedy species <br />(Kochia and Crisium spp. ). The weedy species aze not suitable for revegetation of the <br />area. <br />Revegetation of the reclaimed area is proposed with two seed mixtures, one for upland <br />mesic azeas and one for marshes and wet meadows. The proposed seed mixtures for <br />each of these environments aze listed in Tables 6.2 and 6.3. (These tables have been <br />modified from those in the current permit.) All of the species included in the seed <br />mixes currently grow on the site, are adapted to the conditions that will exist on the <br />reclaimed azeas, aze desirable species for wildlife use, or aze species that have been <br />successfully used for revegetation of disturbed sites. All of the species included in the <br />seed mixes aze native to Colorado. The seed mixes include representatives of cool and <br />warm season species that are commonly encountered in native grasslands. <br />The seeding rates listed in Tables 6.2 and 6.3 will ensure the placement of a minimum <br />of 40 seeds per squaze foot, consistent with Natural Resource Conservation Service <br />recommendations for reclamation of disturbed sites. <br />Seeding will be conducted employing broadcast or drill seeding methods, with seed <br />being covered using machine methods or raked in by hand. Planting and seeding of <br />reclaimed area will occur during the first normal planting season after completion of <br />backfilling, regrading, and topsoil replacement, but no later than November 15 of the <br />year in which the prior activities are completed.
