To give geographical context to our data, we have summarized our results following our five
study area divisions described in our methodology. Additionally, each site represents combined
data from two separately situated motion-triggered cameras set up within the same vicinity.
CASCADES MOUNTAINS
North Cascades
Designated as the area North of US 2 and west of US 97, the North Cascades region consisted of
two sites in 2013. Both the Ice Lake and Union Gap sites were dedicated to wolverine detection
(Table 1). Due to terrain conditions, Ice Lake was established later in the season than the other
two North Cascades sites. Because of this, the Ice Lake site monitoring will carry over into the
2013-2014 Winter monitoring season.

Ice Lake was the only North Cascades site to receive documented visits by species from all three
priority levels, including a visit from a target species (wolverine) for the 2013 season (Table 2).
Though a wolverine was documented at the site, identifiable chest blazes were not captured on
camera as a result of misapplied lure. The site was established within the known home range of
Sasha, a previously documented female wolverine through the North Cascades Wolverine
Study who was believed to be denning in this area. Our goal was to record not only Sasha's
presence but kits or other evidence of her reproduction. Therefore, while we did document
wolverine presence we were unable to specifically link the photograph to her and we did not
document reproduction. This site will continue to be monitored through the winter under the
guidance of Forest Service biologists in the Entiat Ranger District and Pacific Northwest
Research Lab in hopes of achieving our goals. Additionally, to aid in identification, gun brushes
will be added to collect hair samples for DNA analysis.
