A shrub density standard is not proposed for the haul road corridor for the following reasons. <br />The maximum width of the disturbance area is approximately 200 feet, representing a <br />minimal disturbance in relation to the surrounding area. Also, the overstocked and decadent <br />shrub stands which dominate the area will be complimented with the addition of areas with <br />succulent herbaceous forage. Both livestock and wildlife will be benefited. <br />Seasonal Variety Revegetation success for seasonal variety in the reclaimed areas will not be <br />evaluated since nearly all the species in the premining vegetation types are cool season <br />species. The seed mixes have been developed to establish the species best adapted to the <br />site, while also establishing species of the same seasonal variety. Thus, since the seed mixes <br />are dominated by cool season species and any reestablishing native species are principally cool <br />season species, seasonal variety measurements are not necessary. <br />Reference Area The extended reference area will be monitored during the period of extended <br />liability to more accurately gauge average cover and production for the various community <br />types and evaluate annual climatic affects on the vegetation. Monitoring will be carried out at <br />the same time during revegetation monitoring activities in order to provide a basis for <br />comparison of the status and continued development of the reclaimed plant communities. <br />References <br />Armstrong, David M. 1975.
