Central Cascades
The central cascades region, defined as North of I-90 to US 2, housed a total of eight sites.
However, six of those sites fell within the I-90 corridor and will be discussed in the following
section. This section describes results of the Chiwaukum and Bootjack Mountain sites (Table 3).
Both sites were established early in the monitoring season. As with previous years, the
Chiwaukum site will remain active during the 2013-2014 winter season. Due to difficulty of
access, the Bootjack Mountain site was decommissioned for the winter but will be reinstated at
the start of the 2014 Spring-Fall season.

During the 2012-2013 monitoring season, these two sites documented four individual
wolverines discovered visually and then, later, confirmed genetically (see figure below). We
kept this site active over the 2013 Spring-Fall season in hopes of documenting the same or new
individuals – and our hopes bore fruit. Late in the season as weather in the mountains cooled
around December, the Chiwaukum site received its first visit of the season (Table 4). At the
same site last year, the first documented wolverine occurred just a month earlier in November.
Although a positive ID on the recently documented individual was not made; hair samples
were collected and will be analyzed for identification purposes.
