The 2001 level of 5191b/ac is significantly (at the 99 percent level of confidence) lower <br /> than the long-term average. Herbaceous production of the Sagebrush reference area over this <br /> period was 1215 Ib/ac. 2001 herbaceous production of 710 Ib/ac was likewise significantly below <br /> average. Production of the Wadge pasture reclaimed area at 2338 Ib/ac was also significantly <br /> below the long-term (11 year) average of 3116 Ib/ac. The proportion of Wadge Pasture <br /> production contributed by alfalfa in 2001 was 22.6 percent, down from 34.5 percent in 1998, the <br />• last time production data were collected there. This represents progress toward a more <br /> reasonable presence of this introduced perennial forb. <br />Woody Plant Density <br />Figure 3 graphically presents shrub density totals for reclaimed areas sampled in <br />Sampling Year Stems/acre <br />All Wadge Pas. <br />• <br />1985 378 NA <br />1987 300 NA <br />1988 314 322 <br />1989 288 476 <br />1990 281 408 <br />1991 228 288 <br />1992 '157 344 <br />1993 253 356 <br />1994 234 271 <br />1995 364 182 <br />1996 209 239 <br />1997 184 210 <br />1998 257 547 <br />1999 381 227 <br />2000 235 393 <br />2001 483 360 <br />16 <br />
