• <br />• <br />activities will include any necessary repair of rills or gullies (detailed at <br />the end of this Tab), reseeding, or grazing management. Grazing management will be <br />centered on the proper use by livestock of the dryland pasture areas in relation to the <br />associated irrigated pasture. These areas will not be irrigated and will only receive an <br />initial fertilizer application at the time of seeding. <br />Additional Revegetation Measures <br />The current narrow band of swale /drainage vegetation running north to west in the western <br />half of the permit area is anticipated at this time to have only limited disturbance. <br />Most likely irrigation tailwater from adjacent fields will still flow in this drainage, <br />supporting the present vegetation to varying degrees. Any disturbances in this area will <br />be seeded with Seed Mix #6 - Irrigated Pasture Mix, Poorly- drained Sites. If the present <br />willow (Salix exiqua) densities are significantly impacted, groupings of willows will be <br />planted in one -half acre blocks. Willow plant materials will be selected as cuttings from <br />local stands or commercially available adapted Salix species. The planting rate for areas <br />requiring reestablishment will be 1000 stems /acre. <br />In order to provide escape cover for upland game birds several field borders are to be <br />planted to a hedgerow composed of Russian olive (Eleagnus angustifolia) and cotoneaster <br />(cotoneaster acutifolia). Both species provide excellent escape and nesting cover for <br />upland game birds, while the fruits of these species are relished both by songbirds and <br />upland game birds (Shaw 1974 and Martin et al. 1961). The hedgerows, totalling 1400 feet <br />in length, will be planted with the above two species in an alternating pattern spaced 5 -8 <br />feet apart. The estimated location of these hedgerows are shown on Exhibit 22 -2 "Postmining <br />Vegetation Map - Nucla East ". <br />Two groupings of cottonwood (Populus anqustifolia and P. sargentii) and mulberry (Morus <br />rubra) plantings will be established in the locations shown on Exhibit 22 -2. Planting <br />densities in each area will be 25 cottonwoods and 15 mulberry. The mulberry and <br />cottonwoods will be alternately placed in the planting area with a spacing of 10 -15 feet. <br />The plantings will be made in a single row along the field boundaries to maintain the <br />integrity and management of the irrigated pastures. <br />Seed Mix #3, detailed earlier in the revegetation methods for the current Nucla Mine, will <br />be used at the Nucla East area for temporary stabilization of disturbed areas which will <br />22 Revised 07/25/91 <br />
