They will include seedbed preparation, nutrient enhancement, temporary- seeding, permanent seeding, and erosion control. ?Methodology for planting sod mats, live stakes, and trees will also be presented. Herbaceous Vegetation Seed Seedbed Preparation: On sites where equipment can be operated safely the seedbed shall be adequately loosened and smoothed. This may require disking and dragging. On sites where equipment cannot operated safely, the seedbed shall be prepared by hand scarifying to provide a roughened surface so that seed will stay in place. If seeding is done immediately following construction, seedbed preparation may be required only on areas where heavy equipment has caused compaction of the ground. Seeding: Temporary seeding - Use where needed for erosion control, when permanent vegetation cannot be established due to planting season and where temporary ground cover is needed to allow native or woody vegetation to become established. Apply the following vegetation at the listed rates. Fall, Winter, and Spring Seeding Per 1000 sq ft Per Acre Millet '/2 lb. 20 lbs. Winter Wheat 1 lbs. 40 lbs. Summer Seeding Per 1000 sa ft Per Acre Sudangrass I lb. 401bs. Browntop Millet 1 lb 40 lbs Permanent Seeding - Use in combination with woody plantings on This mixture can be planted at any time but will do best in spring or late fall. Spring planted seed should be treated with a cold wet chill process to maximize germination. Fall plantings should be planted with a lightly sown cool season annual to hold soil and does not need to be chilled. Seeding should be done evenly over the area using a mechanical or hand seeder. A drag should be used to cover the seed with no more than '/2 inch of soil. Where a drag can not safely be utilized the seed should be covered by hand raking. All seasons: WNC Wetland Diversity Mix (as described on the attached sheet) '/4 lb. per 1000 sq. ft. and 25 lbs. per Acre Erosion Control: All seeded areas, areas disturbed by heavy equipment, or other areas disturbed by mitigation activities should be protected from erosion by installation of erosion control blankets or matting. Woody Vegetation Live stakes (uprooted material) Live stake material should be dormant and gathered locally or purchased from a reputable commercial supplier. Stakes should be % to 3 inches in diameter and living based on the presence of young buds and green bark. Stakes should be kept cool and moist to improve survival and to maintain dormancy. Stakes should be driven into the ground using a rubber hammer or by creating a hole and slipping the stake into it. The ground around the stake should be firmed against the stake after planting. Stakes should be placed so that 75% of the stake is below the ground and 2 or 3 buds are above ground. Stakes should be planted on a 2 - 3 foot spacing and at a density of 160 - 360 stakes per 1000 sq. ft. Bare rooted or potted stock Care and handling: Desirable trees and shrubs on the construction site should be dug and stored. These plants should be stored in a cool moist environment or heeled in. Roots of bareroot stock should be kept moist during planting operations. Bareroot material should only be planted during Winter and early Spring. Container or potted stock shall be kept moist at all times. Do not let roots freeze or dry out prior to planting. Site Preparation: The soil in the area of tree planting should be loosened to a depth of at least 1 foot. This is only necessary on hard compacted soil. Planting: On site material - Transplants should be replanted to the same depth they were originally growing. Potted stock - Planting should be done mechanically or by hand using a shovel. The planting trench or hole must be deep enough and wide enough to permit roots to spread out and down without J-rooting. Potted stock should be planted in a hole 2-3 times the diameter of the root ball and at the same depth as the root ball. When setting plants, be certain to plant them high. Locate the root ball on solid soil and not loose backfill. Wire baskets do not need to be completely removed from large field grown trees. Be sure to remove plastic liners or synthetic burlap materials. Construct an earthen dam 4-6 inches high around the drip zone area of the plant after planting. This will allow for self watering and runoff will be minimized. 2 Bare rooted stock - Bare rooted material can be planted using a hoedad or a dibble bar (see diagram below). Planting slits for bare rooted material should be 6-8 inches in diameter and should be at least 8-12 inches deep. Damaged roots should be trimmed. Plants should be placed with the root collar slightly below the soil surface. Holes and slits should be closed completely, including and especially at the bottom of the hole. Spacing of rooted Woody Vegetation - the following guidelines should be used for spacing rooted woody vegetation. Type sp acing # per 1000 sq. ft. Shrubs, less than 10 ft. in height 3 -6 ft. 27-111 Shrubs and Trees, 10 -25 ft. in height 6 - 8 ft. 15 - 27 Trees greater than 25 ft. in height 8 -15 ft. 4-15 Minimum 420 stems per acre Guidelines for Planting Bare-Root Plan# M#e trar,6port mss, keep the Mts dam arxd gilt, of the sue.

These plantings will take place in the winter or early spring. Spacing suggestions should be used as guidelines, but can be varied depending on species requirements and landscape objectives. For example species that are commonly found growing in clumped distributions should be planted that way. It is desirable for the final distribution of trees and shrubs to have a more natural, random appearance. In order to accomplish this exact spacing should be avoided and mixing of various species should be done. 4 Plants native to the riparian and wetland areas of Western North Carolina Type Common Name Scientific Name Flooding Light Wetland pH wildlife region val. 1 American Pillwort Pilularia americana Reg sun obli 0-7 birds all 1 Cinnamon Fern Osmunda cinnamomea Irreg to reg Part to shade Fac.wet 0-7 birds all 1 Netted Chain Fern Woodwardia areolata seas to reg all obli less birds all 1 Royal Fern Osmunda regalis seas to reg Part to shade obli 0-7 birds, sm all 1 Sensitive Fern Onoclea sensibilis Irreg to reg all facu 0-7 birds all 2 American Lotus Nelumbo lutea reg to perm sun oblig 0-7 birds,SM all 2 American Pondweed Potamogeton nodosus perm sun oblig 7 birds,SM all 2 Arrowhead Sagittaria latifolia seas-perm sun to shade oblig all B, Sm all 2 Broad-leaf Cattail Typha latifolia seas-perm sun oblig all B, Sm all 2 Cardinal Flower Lobelia cardinalis irreg-seas sun fac.wet 0-7 B, Sm all 2 Hollow Joe-pye-weed Eupatoriadelphus fistulosus irreg-seas sun facu 0-7 birds all 2 Narrow-leaf Cattail Typha angustifolia seas-perm sun oblig all B, Sm all 2 Pickerelweed.
