During surveys that were initiated in November 2009 and conducted each winter through
the winter of 2011-2012 to evaluate lynx winter habitat and prey base conditions, the
following observations were made.
During the three years of winter surveys observations indicated that large portions of the
LMA and surrounding areas lack suitable winter habitat for either lynx or snowshoe
hares. Most of the suitable habitat and associated prey in the LMA are found at
elevations above those areas where exploration drill sites and access roads would be built.
Above 9400 feet the spruce -fir is denser and has better conditions for snowshoe hares
than the more open stands found at lower elevations. Within the better stands at higher
elevations, the numbers of snowshoe hares is higher than at lower elevations. Below 9400
feet the habitat is dominated by aspen with pockets of spruce -fir. Most of the spruce -fir
pockets are limited to drainages. In these areas a few snowshoe hares are found around
