97 <br />biomass of grass species also allowed the lowest biomass of invading <br />grass species. <br />The biomass of invading grass species showed a significant response <br />(P=.0011) between seed mixture and panel (Figure 35). Gn Panel 3 the <br />biomass of invading grass species was significantly higher in the native <br />seed mixture than in the other two seed mixtures. Although the native <br />seed mixtures generally showed a higher bionass of invading grass species <br />across all panels, the reason for this sharp increase in Panel 3 is not <br />known at this time. <br />Total Biomass of Forbs. The only significant difference observed in <br />this section was among the seed mixtures as they influenced the total <br />biomass of seeded forbs (Appendix A, Table 11). The combination seed <br />mixture contained significantly higher biomass than the native seed mix- <br />ture and higher biomass than the introduced seed mixture. These results <br />1 of seeded forb biomass by seed mixture directly correlate with the number <br />fii7 and seeding rate of forbs per seed mixture as presented earlier. <br />p~ Total Biomass of Shrubs. Significant differences were seen in shrub <br />tt~~ biomass according to seed mixture when the total shrub biomass for seeded <br />and invading species was examined. This same response was observed when <br />seeded shrub species were examined separately. In both cases, the com- <br />bination and native seed mixtures had significantly greater shrub biomass <br />rip-;c+` <br />than the introduced seed mixture. The low shrub biomass in the intro- i ^ <br />duced mixture is caused in part by the low seeding rate and the poor <br />gro•,vth response of the introduced shrub species. <br /> <br />~~ <br /> <br />
