14 Reve eg tation The focus and goal of revegetation at the site will be the establishment of effective vegetation cover that will provide a stable self-sustaining vegetation community that compliments the native vegetation on the surrounding areas. To this end, replacement of vegetation will focus on establishment of a vigorous herbaceous community with scattered low shrubs and half-shrubs. Two specific seed mixes have been developed for the site; one seed mix will be planted adjacent to the pond within disturbed areas. The second seed mix is specifically designed to minimize erosion from wave and wind action along the east shoreline and margins of the pond. Seeding Herbaceous revegetation of the reclaimed area is proposed to minimize impacts to the physical environment by reducing wind and surface water erosion, and impacts to the biologic community by providing wildlife habitat, as well as food and shelter in the immediate area. Revegetation of the disturbed area is proposed with the two attached diverse seed mixtures. All of the species included in the seed mixes are commonly encountered in Colorado, are palatable for wildlife, and are proven revegetation species. All of the species included in the seed mixes aze native to Colorado or naturalized through range or agricultural plantings. The seed mixes include representatives of cool and warm season species to maximize cover and seed production throughout the summer months. The seeding rate was determined from the selected plant species to ensure placement of a minimum of 40 seeds per square foot, consistent with Natural Resource Conservation Service recommendations for reclamation of disturbed sites. Seeding will be conducted employing drill or broadcast seeding methods, with seed being covered using machine methods or raked in by hand. Planting and seeding of vegetation will occur during the first normal planting season after completion of backfilling and regrading, but no later than November 15 of the year in which the prior activities are completed. To take advantage of climatic fluctuations, two seeding windows are proposed, March 15-July 1 and September 1 to November I5. Shrub Planting To promote development of wildlife habitat, minimize erosion along the pond margins (particularly the east shoreline) and provide additional species diversity, planting of willow stakes in natural groupings along the pond shoreline is proposed. Coyote willow (Salix exigua) stakes will be planted to encourage development of willow copses and retard erosion. Willow stake planting locations will be determined in the field, with each planting comprising from 25 to 50 willow stakes. Irri ap lion Irrigation maybe employed during revegetation in areas where fluctuating water levels adjacent to the pond may cause drought stress to seeded or planted species. The irrigation will be of a sprinkler irrigation type and will be employed only through the first two growing seasons as required. 2RR app CDMG 112
