• age 2 <br />'o Blanco County <br />ovember 30, 1999 <br />3) RECLAMATION RECOMMP:.DATIONS - At the time the gravel pit :_ <br />closed, the following reclamation recommendations should be <br />followed to help insure a more successful revegetation of the <br />site: <br />The site should be recontoured and smoothed to slopes no <br />steeper than 3:1 and preferably flatter, where practical. The <br />flatter the slopes, the more opportunity of re-establishing the <br />site with adequate vegetation. All areas which are compacted <br />must be ripped. <br />The limited topsoil which was stockpiled, should be spread <br />evenly over the re-contoured site to the extent possible to a <br />depth of 4 inches or more. The site should then be tilled and <br />firmed to prepare a suitable seedbed. <br />Seeding of the site should be done in the late fall (October <br />15th and later) prior to the soil freezing. The seed should be <br />drilled with a grass drill having double disk openers and packer <br />wheels. Planting depth should be approximately lJ2 inch. If the <br />seed will be broadcast instead of drilled, then the recommended <br />seeding rate below must be doubled. If broadcasting is done, the <br />area should be harrowed or dragged to incorporate the seed into <br />the soil. <br />The following grass species are recommended to reseed the <br />site. This rate is based on pounds of pure live seed (PLS) per <br />acre. <br />Specie Variety Pounds PLS/acre <br />western wheatgrass Arriba 3.2 <br />Thickspike wheatgrass Critana 2.2 <br />Streambank wheatgrass Siberian 2.2 <br />Russian wildrye Vinal 2.0 <br />Crested wheatgrass Ephraim 2.0 <br />Total Pounds PLS/Acre 11.6 <br />Due to the relatively small size (7.8 acres) of this <br />disturbed site existing native grasses, forbs and shrubs should <br />invade and diversify the site. <br />The most critical and important treatment to achieve the <br />establishment of an adequate stand of planted species on this <br />site is proper and timely weed control. Invasion and <br />establishment of weeds must be controlled in this region of very <br />low annual precipitation. The limited moisture must be reserved <br />for the new planting, in order for it to become established. <br />Weed control must be performed early during the first growing <br />season to adequately control weeds. More than one treatment may <br />be needed. Herbicide labeling should be followed. Noxious weeds <br />must be controlled. <br />The site should be deferred from grazing a minimum of at <br />least two full growing seasons to allow the planted vegetation to <br />become adequately established on the site. <br />
