NATURAL RESOURCES CONSERVATION SERVICE <br />CONSERVATION PRACTICE STANDARD <br />CRITICAL AREA PLANTING <br />(Acres) <br />CODE 342 <br />DEFINITION <br />Establishing permanent vegetation on sites that <br />have or are expected to have high erosion rates, <br />and on sites that have physical, chemical or <br />biological conditions that prevent the <br />establishment of vegetation with normal <br />practices. <br />PURPOSE <br />• Stabilize areas with existing or expected <br />high rates of soil erosion by water. <br />• Stabilize areas with existing or expected <br />high rates of soil erosion by wind. <br />• Rehabilitate and revegetate degraded sites <br />that cannot be stabilized through normal <br />farming practices. <br />• Stabilize coastal areas, such as sand dunes <br />and riparian areas. <br />CONDITIONS WHERE PRACTICE APPLIES <br />This practice applies to highly disturbed areas <br />such as active or abandoned mined lands, <br />urban conservation sites, road construction <br />areas, conservation practice construction sites, <br />areas needing stabilization before or after <br />natural disasters such as floods, hurricanes, <br />tornados and wildfires and other areas degraded <br />by human activities or natural events. <br />CRITERIA <br />General Criteria Applicable To All Purposes <br />Conduct a site investigation to identify any <br />physical, chemical or biological conditions that <br />could affect the successful establishment of <br />vegetation. <br />Species selected for seeding or planting shall be <br />suited to current site conditions and intended <br />uses. <br />342-1 <br />Do not establish plants on the state noxious <br />weeds list in critical area plantings. <br />Selected species will have the capacity to <br />achieve adequate density and vigor within an <br />appropriate period to stabilize the site <br />sufficiently to permit suited uses with ordinary <br />management activities. <br />Specify species, rates of seeding or planting, <br />minimum quality of planting stock such as pure <br />live seed (PLS) or stem caliper, method of <br />seedbed preparation, and method of <br />establishment, before application. Use only <br />viable, high quality seed or planting stock. <br />Complete seeding or planting at a time and in a <br />manner that best ensures establishment and <br />growth of the selected species. Specify what <br />constitutes successful establishment, e.g. <br />minimum percent ground/canopy cover, percent <br />survival, stand density, before application. <br />Use Colorado Plant Materials Tech Note 59, <br />Table 2, to schedule planting dates for the <br />selected species, while optimizing soil moisture <br />for germination and/or establishment. <br />Apply soil amendments (e.g. lime, fertilizer, <br />compost) according to a nutrient management <br />plan, at rates necessary to insure stand <br />establishment. <br />Protect plantings from pests (e.g. weeds, <br />insects, diseases, livestock, wildlife) as <br />necessary to ensure stand establishment. <br />All soil amendment, nutrient and pest <br />management applications shall follow the <br />requirements in the Colorado Field Office <br />Technical Guide. <br />Conservation practice standards are reviewed periodically and updated if needed. To obtain <br />the current version of this standard, contact the Colorado Natural Resources Conservation <br />Service State Office or visit the Colorado electronic Field Office Technical Guide. <br />NRCS, CO <br />November 2007 <br />
