• Within the post-mine vegetative community, the food
component for brood rearing will be provided by insects
and succulent vegetation on reclaimed areas early in
chick development. Later into the summer months, as food
sources dry up on the upland slopes, food will be
available near water impoundments and drainage bottoms
being returned to the post-mining topography. The
literature indicates no optimum distance between nesting
sites and food sources. Evidently, the location of
nesting sites are independent of food sources, rather,
the nesting locations are based on available cover, and
the grouse movements are tied to the availability of
succulent vegetation.
Additional Mitigation Measures
The pre-planning for a minimum amount of annual disturbance, the
establishment of herbaceous species, the replacement of native
shrub species, and habitat improvement techniques are the most
important areas for minimizing impacts to wildlife, several other
protection measures are in effect.
•
Electric power lines located in the permit area will be constructed
in accordance with the requirements of Section 4.18 to minimize
potential electrical hazards to large raptors.
Vehicle use within the permit area is limited to the active mining
area and the various support facilities. Off-road vehicle use is
kept to a minimum and is usually only authorized for surveying,
environmental data collection and monitoring, security, etc.
Travel by foot, which causes much more disturbance to wildlife than
vehicle traffic, is highly unlikely outside active mining areas.
Hunting with firearms inside Colowyo's Federal lease is strictly
prohibited.
Speed limits in the mine area are limited to 25 mph in the mine and
45 mph on the main haul and access roads. Reduced speed limits
tend to reduce the likelihood of collisions between vehicles and
