Usa only <br />viable, high quality sped or planting stock <br />Sde preparation and seeding or planting shall be <br />done at a time and manner that best ensures <br />survival and growth of the selected spec;es. <br />Specify successful establishment criteria such <br />as mimmum percent ground canopy cover, <br />percent survival and stand densely, etc., before <br />practice application. <br />Apply facilitating practices that enhance plant <br />growth such as tertihzation and mulching to <br />accelerate establishment of selected species. <br />Fertilizer and soli amendment application <br />methods, rates and liming shall be consistent <br />with the Colorado Nutrient Management 590 <br />Conservation Pradlce Standard <br />Do not establish state listed noxous weeds In <br />critical areas.
