for an increased sagegrouse brood population over
that which the area supported in an overgrazed
condition.
4. Since 1976, numerous areas of thick, decadent
stands of the mountain shrub vegetation within and
adjacent to the lease area have been cleared of
brush as part of the big game mitigation program.
As a result of the brushing, the production of
succulent herbaceous vegetation has increased,
offering more forage for the sagegrouse brood
population.
The above changes in management practices of the
rangeland around the Colowyo mining area contribute
to the increased capability of supporting any
displaced sagegrouse nesting and brooding
population. No additional treatments to mitigate
for a displaced sagegrouse population is felt
necessary due to the present mitigation in effect,
nor would other methods likely be as effective.

II. Post-mining Miti4ation for Saoeorouse
As stated in the Permit Application, sagegrouse use
of the area to be mined is for nesting and brood rearing
purposes.
According to information contained within the Bureau
of Land Management Technical Note #330, "Habitat Require-
ments and Management Recommendations for Sage Grouse,"
the most important factor for nesting habitat in the
sagebrush vegetation type is sagebrush. Within this
vegetative community, the majority of sagegrouse nests
occur under sagebrush. It is assumed that within the
mountain shrub vegetative community, sagegrouse nest
would be found under the mountain shrub components as
well as sagebrush.
