Wolf Management
• A lawsuit to relist wolves is being reviewed in
Federal Court in Missoula. The decision whether to
place wolves back on the Endangered Species List or
to allow hunting seasons to continue for 2010-2011
may not be made until late spring .
• Wolf hunting seasons and quotas will be addressed
by the IDFG Commission at their August meeting.
