Broadcast seeding would occur preferably within five days of spreading the topsoil in <br />order to reduce the need to mechanically roughen surface crusting. If spreading of <br />topsoil occurs at a time no[ suitable for seeding, broadcast seeding will occur as soon as <br />the best conditions for seed growth take place. <br /> The composition of the grass/forb seed mix to be used in National Forest System lands <br />' is presented in Table 2.2. <br /> Native grass and forb seeds not commercially available would be hand collected during <br /> the growing season (Summer/Fall) and properly stored until its application to the <br /> restored areas. Most shrub and tree species should be obtained from the Colorado State <br /> Forest Service. If not available, they should be locally collected on site and propagated <br />by a commercially available service. Preferred shrub species for re-establishment <br /> include: Gambel's oak (Quercus gambelii), Soapweed yucca (Yucca glauca), Mountain <br /> mahogany (Cercocarpus montanus), Wood's rose (Rosa woodsii), Cliff spirea <br /> (Holodiscus dumosus), and Bearberry (Arctostaphylos uva-ursi). Gambel's oak and <br /> mountain mahogany would be propagated offsite, commercially, from local materials <br /> and planted in zones indicated on the map in Figure 2.1, at the rate of 336/acre. The <br /> other shrubs listed will be planted as nursery stock, as available, at the rate of 200/acre <br /> in locations also shown on the map in Figure 2.1. <br />' These shrubs should be planted as tublings with watering at planting. The planting <br />process will include construction of a saucer azound each one, installation of anchored <br />landscape fabric (one squaze yazd), and placement of a wire cage (1" x 4" welded wire <br />cylinder, 3 fl. height, one foot diameter) anchored with rebaz. Supplemental watering <br />should be carried out during the fust growing season on at least a monthly basis. Also, <br />t polyacrylamides may be used to reduce competition from grasses and minimize <br />moisture fluctuations. <br />11. The composition of the seed mix proposed for use in private lands by the owner is <br />presented in Table 2.3. <br /> <br /> <br />1 <br /> <br />Hydrosphcre Resource Consultants, 1002 Walnul Street Suite 200, Boulder, CO 80302 <br />1 <br />
