There is a good survival and uniform distribution of the seeded species across this site. The cover
of perennial grasses and forbs has exceeded that of native rangelands, however, production from
both remains below that of native rangelands. Production values of perennial grasses, forbs and
shrubs have all made substantial gains from levels recorded in 2007. Cover of shrubs declined
8% from levels recorded in 2007 possibly from loss juvenile plants present in 2007. However, a
substantial increase in shrub production occurred in 2008 most likely from surviving shrubs
nearing maturity.
Substantial reductions in cover and production of annual grasses and weedy forbs occurred in
2008. No annual grasses were encountered within the study area in 2008. The cover of weedy
forbs and bare ground is very close to that of native rangeland.
The following statements compare the values measured in 2008 for Well Pad IA-4HI to the
reclamation goals/requirements:
• The production of perennial grasses is 84 % and production of perennial forbs is 75 % of
that on native rangeland; nearing the requirement of being equal of that measured on
native rangeland.
• The cover of all perennial herbaceous species exceeds that of native rangeland by 31 %;
substantially exceeding the requirement of being equal of that measured on native
rangeland.
