I ~ As can be seen in Figure 1, the allowable herbaceous cover of all reclaimed areas falls above the <br />standard set by the Mountain Brush and Sagebrush reference areas. <br />Presented below is a compilation of cover data from 1987 to 2004 for the areas sampled in 2004: <br />Thal Perteny <br />PRFA 196] )966 1909 1990 1991 1993 199] <br />199] ReU. <br />PEGOCO Pas - -- - - - - ]Ol <br />WOC2e Peyiur - ]9.1 ]°6 65l ]0.6 ]l3 ]i5 <br />MN.

It is interesting to note from these data that the average <br />cover (as well as production, see below) of the ungrazed areas is lower than that in the grazed <br />Wadge Pasture reclamation throughout the period of record. This provides support for the idea <br />that moderate to light grazing (such as has occurred in Wadge Pasture) tends to enhance plant <br />• growth most likely by encouraging more rapid mineralization of dead plant parts leaving nitrogen <br />among other nutrients more readily available. <br />Herbaceous Production <br />Calculation of 90 percent of the production performance standard appropriate for 2004 sampling <br />is as follows; 90 percent of the Herbaceous Production Standard = 0.90[0.83(664) + 0.17(1024)] <br />= 653 oven-dry Ib/ac. As can be seen in Figure 2, all reclaimed areas sampled equaled or <br />exceeded 90 percent of the herbaceous production standard, although the data are not corrected <br />for "allowable" production (i.e. subtracting production from annual/biennial species that exceed <br />10% of total production}. <br /> xa,m<aaa, Pmtluctlm lesenaryrm w..y21 <br />RREP 190] 1900 IB09 1880 1991 1993 199] 1991 I%6 19% 199] 1990 1999 2000 3001 2W3 200] 2001 <br />1%>R<el. - - - - - - - - - ~- - - t9ll - 106 - - ID20 <br />PECOLO Pys -- - - - - - ]235 - - 1]65 - 1563 - - 1615 919 Y1J0 1915 <br />WaE9e DmNr - 3050 2201 2]11 38)l ]161 ]58] 3]16 15]0 J]05 -~ 1220 2)35 - 3]]0 008 N23 219] <br />MN. &.
