The juniper ow~nasrity, oonsistitg of <br />scattered individual juniper trees, was located within the agricultural <br />type (hay meadow) thus the production, rover and species acsposition of <br />the ~mdersb~ry vegetation appeared the sane as that of the hay meadow. <br />Therefore, the understory vegetation (alfalfa) was rot sa;tpled since it <br />was equivalent iv, and•a part of, the hay meadow. All trees in this juni- <br />per wnmwruty were quantitatiezly sampled for density and basal area deter- <br />minations. The small tree oanmmiity along the riparian type was also <br />sampled for tree density and basal area data; the rest of the riparian <br />type (less than 1 acre) was sampled for SpeGieJ oaeposition. Much of this <br />one acre riparian site was a marsh ~ntainu~g standing water, thus vegeta- <br />tive production and Dover estimates for this sn3ti area were rot possible. <br />'i9roe .ry~land sagebrush and grassland type were systematically sailed to <br />gather production, Dover, frequency and shrub height data for the 1979 <br />growing season. Reference or control plots, approximately 2.5 acres in <br />size, were situated in these two types away from potential disturbance <br />(affected) areas. The exact location of all reference areas are shown <br />on the vegetation cover map (Appendix A). These control sites were selected <br />on the basis of their containing vegetation species, soils and topographic <br />aspects generally charactaxistic o£ the upland say hr+.~h and grasslarcl <br />vegetation oommmities sanpled. All control plots were sampled in a <br />systematic manner to gather axparison vegetative production, Dover, fre- <br />quency and shrub height data for the 1979 yrowing season.
