Human-Polar Bear Conflict Management is a
Priority Issue for the Range States (2009
Meeting in Tromso, Norway)
• Determine where and when, specifically, we can
expect to see increased conflicts resulting from
accelerating climate change.
• Recommend methods to minimize the risk of humanpolar bear conflicts in order to promote both human
safety and polar bear conservation.
2013 Range States Meeting, Moscow
• Affirmed that the Polar Bear-Human Information Management
Recognized the need for financial and staff support for this work,
System (PBHIMS) is the appropriate tool for cooperation among
and encouraged the timely dissemination of best practices for
the Range States for documenting human-bear conflicts, and
mitigating human-bear conflicts.

Reported U.S. Conflict Bear Kills by Village,
1999-2013, (n=163)
• Focus limited management resources/efforts.
• 4 villages and Cross Island account for 82% of reported
conflict kills for this period.
• Can prioritize even more by looking at per capita rates of
conflict kills.
Efficacy of Deterrents
• Electric fencing has been very successful (>90%) in protecting
igunaq (fermenting walrus meat) caches in Nunavut.
• Most caches not protected by the fencing have been lost to
bears.
• Camera monitoring shows that bears now travel right by
fences without testing them further.

We also have data on 64 attempted attacks on people (i.e. the
bear was intent on attacking, but was killed or physically deterred prior to
injuring a person).

Accomplishments Since 2009
1. Created a science-based conflict database
2. Populated it with data from at least one priority subpopulation for
each country
3. Developed a Sharepoint site for information sharing and possible
future data sharing
4. Draft papers on polar bear attacks and the efficacy of bear spray
5. Face-to-face working group meetings- 2012 Churchill, 2013 Tromsø,
2015 Copenhagen
6. Compiling range-wide bear safety information
7. Developed techniques for use of electric fencing (Nunavut- Bob
Hansen)
8. Developed two and 10 year actions plan for addressing human-bear
conflicts at the circumpolar level for the CAP
9. Have engaged multiple partners (government, NGO, and private
industry) in support of this initiative
Challenges Impeding This Group’s
Work
1. Lack of dedicated resources from the Range States in
terms of funding and staff time to accomplish assigned
tasks
2. Lack of a mechanism to accept diverse funding sources
for this group’s work
3. Unfilled vacancies of Range State appointed delegates
to the working group
4. Getting travel approval to attend face-to-face meetings
5. Lack of data sharing agreement
Future Funding Needs For This
Initiative
1. Continue technical support for database
2. Produce consistent Range State bear safety
materials based on PBHIMS data
3. Publish peer-reviewed papers from PBHIMS
data
4. Travel to face to face meetings
5. Applied research- e.g., resurrect Churchill
research program from the 1980s
