Klickitat Wildlife Area Projects: Wildlife Area Manager VanLeuven reviewed
past photos taken during and after controlled burns and wildfires at the Wildlife
Area as well as grazing unit photos over several years. VanLeuven discussed
the history of the prescribed burn program at the Wildlife Area with DNR crew
supervisor in context of present and future management. VanLeuven also contacted
the Wildlife Area’s Citizen Advisory Group members to set up their next
meeting and worked on several maintenance issues at the Wildlife Area headquarters.

Post-season Elk Survey: Regional Wildlife Program Manager Jonker and
Biologist Holman conducted an aerial post-season elk survey in the Lewis River
(560), and Siouxon (572) Game Management Units. Each of these Units are located
at relatively high elevations in the Cascades and are held primarily in U.S.
Forest Service ownership. Large amounts of persistent low-elevation snowpack
made the elk difficult to locate. The animals were primarily located in the
larger (low elevation) riparian areas or within dense forest stands (where they
are essentially impossible to see).
A total of 108 elk were classified on the survey. The survey revealed a bull:cow:calf ratio of 4:100:40. Small sample size and poor representation of bulls in the survey make conclusions regarding the male segment of the population inconclusive. The presence of 40 calves per 100 cows is encouraging given the severity of the 2007-08 winter.
Wildlife
Diversity Division
Winter Carnivore Survey: Biologist Anderson has been working
with the USFS and volunteers to initiate a pilot carnivore camera detection
project near Mt. Adams in the South Cascades. Baited camera stations are being
set at elevations above 5500 ft. with an emphasis to detect potential wolverine
movements. WDFW and the USFS are interested in determining if recent observations
of wolverine indicate frequent use of the South Cascades or rare individuals
moving through the area. This winters work is focused primarily on looking at
logistics for future winter surveys with the potential of actually documenting
any wolverine currently in the area.
