• The composition of perennial forbs exceeds that of native rangeland by 29 %; substantially greater than the required 4 % of that measured on native rangeland. • The composition of shrubs is 91 % of that on native rangeland; substantially greater than the required 12 % of that measured on native rangeland. All the reclamation goals/requirements are being met or exceeded at this site with the exception of production from perennial grasses. It is likely the site will achieve the requirements within a few years without additional reclamation efforts as perennial species continue to mature and increase their production. Well Pad Site 4-3H: The ground cover data in Table 10 is summarized by class of vegetation and cover type from data presented by plant species or cover type in Appendix Table A4. The production data presented in Table 11 is summarized from the annual above-ground vegetation biomass production for each plant species as shown in Appendix Table A4. The species composition data presented in Table 12 is summarized by class of vegetation from the percent composition of each plant species encountered as determined by each species contribution to total biomass production as shown in Appendix Table A4. The following tables compare the data collected in 2008 for well pad site 4-3H to data collected from previous years as well as data collected in 2008 from nearby native rangelands.
