There is a good survival and uniform distribution of the seeded species across this site. Both
cover and production of perennial grasses exceeds that of native rangelands. Production values of
perennial forbs and shrubs remain. below that on native rangeland. Substantial reductions in
cover and production of annual grasses and weedy forbs occurred in 2008. Cover of shrubs
declined 14% from levels recorded in 2007 but remain above levels measured for native
rangelands in 2008.
The following statements compare: the values measured in 2008 for Well Pad 3A-4H to the
reclamation goals/requirements:
• The production of perennial grasses is 14 % greater that measured on native rangeland.
The production of perennial forbs is 13 % greater that measured on native rangeland.
Both are exceeding the requirement of being equal for successful reclamation.
• The cover of all perennial herbaceous species exceeds that of native rangeland by 22 %
exceeding the requirement of being equal of that measured on native rangeland. The
cover of both perennial grasses and perennial forbs increased in 2008 over that measured
in 2007. The cover of perennial grasses increased 17 % above that measured on native
rangeland in 2008. The cover of perennial forbs increased 38 % above that measured on
native rangeland in 2008.
• The composition of perennial forbs is 84 % of that on native rangeland in 2008;
substantially greater than the required 4 % of that measured on native rangeland.
