We also <br />discussed additional issues regarding wildlife and reveget~ttion which <br />were brought to your attention in a letter of February 10, 1983, also <br />from Jim Herron. I have summarized my understanding of our discussion <br />below. Items we discussed in a phone conversation on April b, 1983 are <br />also reflected in this letter. <br />Completeness Issues <br />• The completeness letter noted that sample adequacy Clad not: been met <br />fur production and that an estimate of tree density for the aspen type <br />had not been provided. <br />You have proposed that herbaceous production be re sampled this <br />summer in all vegetation types, and vegetation cover be resampled in the <br />aspen type. Herbaceous production will be estimated by clipping randomly <br />located m2 plots. Production cages will be set out prior to the <br />yrazing season; a maximum of 50 samples will be collected in sagebrush <br />and mixed brush affected areas and 30 samples will be collected in <br />reference areas. The access road corridor will not be included in the <br />sampling. Amaxilnum of 30 cover and production samples will be required <br />in the aspen affected area, due to the limited extent of the type in the <br />affected area. <br />Aspen density will be estimated by a 50 x 5m belt transect method. <br />A maximum sample size of 30 transects was agreed upon. <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel.
