Revision <br />February 1982 <br />• Willow (Salix spp.) and cottonwood (Populus spp.) rooted cuttings may also <br />be planted if soil moisture is adequate for their establishment. <br />In the fall (mid- to late September) the area between the riprap and <br />low water will be planted with sprigs of spike-rush (Eleocharis spp.) and <br />sedges (Carex spp.) which will be locally collected. These sprigs will be <br />planted in clumps at approximately five-meter intervals along the river- <br />bank. <br /> Mulching <br /> On slopes of less than 30 percent, a we ed-free (if commercially <br /> available straw mulch will be applied by a straw blower at the rate <br /> of two tons per acre. The straw mulch will be anchored to the ground <br />• mechanically by crimping the straw into the ground. Steeper slopes <br /> will be hydromulched with 1.5 tons per acre. Jute matting will be <br />used to both anchor the straw mulch and to protect the topsoil <br />against erosion. <br />Irrigation <br />Irrigation is not proposed, since the species selected for revegeta- <br />tion are well adapted to the climatic regime of the Hawk's Nest area. <br />Should lower than average precipitation occur so that seed germination is <br />reduced, irrigation may be used on a short-term basis. Otherwise, irriga- <br />tion will be used only if initial revegetation attempts fail and if it is <br />considered to be a major factor in successful revegetation. <br />• Monitoring <br />Monitoring of reclaimed areas will begin the third year following <br />seeding. Permanent quadrats randomly located in <br />2.05-53" <br />
