concentrated sites with 90 percent statistical confidence. Density shall be determined by the <br />number of countable tree and shrub stems per unit area. Woody plant densities will be <br />measured in a 1m x 50m (50m or larger direct count quadrat. All quadrats will be randomly <br />located and sampling intensity will be to statistical adequacy or a specified maximum sample <br />size determined in consultation with CDMG. The counted tree or shrub will be alive and <br />healthy and in place at least two growing seasons. When counting stems, consideration will be <br />given to shrubs, which spread by above or below ground runners. <br />A shrub density standard is not proposed for the haul road corridors for the following reasons. <br />The maximum width of the disturbance area is approximately 200 feet, representing a minimal <br />disturbance in relation to the surrounding area. Also, the overstocked and decadent shrub <br />stands, which dominate the area will be complimented with the addition of areas with succulent <br />herbaceous forage. Both livestock and wildlife will be benefited. <br />Seasonal Variety <br />Revegetation success for seasonal variety in the reclaimed areas will not be evaluated since <br />• nearly all the species in the premining vegetation types are cool season species. The seed mixes <br />have been developed to establish the species best adapted to the site, while also establishing <br />species of the same seasonal variety. Thus, since the seed mixes are dominated by cool season <br />species and any reestablishing native species are principally cool season species, seasonal variety <br />measurements are not necessary. <br />Reference Area <br />The extended reference area was monitored during the period of extended liability to more <br />accurately gauge average cover and production for the various community types and evaluate <br />annual climatic affects on the vegetation. Monitoring will no longer be carried out as sampling <br />efforts will be shifted to bond release activities in order to provide a basis for evaluating and <br />testing for success of revegetation efforts. <br />References <br />Armstrong, David M. 1975.
