5.1 Human Polar Bear Conflicts Working Group
Preparing for an Ice-Free Arctic: Mitigating Human-Polar Bear Conflicts James Wilder, IUCN Polar Bear Specialist Group Range States’ Human-Polar Bear Conflict Working Group Sea Ice Available = Fewer Human-Bear Conflicts Photo courtesy of Terry DeBruyn The Arctic Ocean will be nearly Ice Free in Summer by 2040, perhaps as soon as 2020 Current 2020s (≈ 3.4 million km2) (≈ 1.0 million km2) Figures from Wang and Overland (2012) Slide courtesy of T. Atwood, USGS 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. for the design of programs to reduce human-bear conflicts; Why We Should Care Main Objectives Range States’ Human-Polar Bear Conflicts Working Group Range State Appointees: • Canada- Daryll Hedman, Melissa Gibbons, vacant (vice-B. Hansen) • Greenland- Sofie Erbs-Maibing, Heidi M. Hansen • Norway- Dag Vongraven, vacant • Russia- vacant, vacant • U.S.- James Wilder, Todd Atwood, Mike Pederson Other Participants: • Russia- A.

York Copenhagen, March 2015 Natural History Observations • • • • • Starvation Drowning Cannibalism Disease Hybrid bears Ashley Cooper/Global Warming Images PBHIMS Facilitates Adaptive Management Management Questions Reported Nunavut DLPKs By Year (1971-2012) and Community (2000-2012) Figures courtesy of Bob Hansen (Government of Nunavut - Dept. of Environment) 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.

Bear-inflicted Human Fatalities, 1900-2014 Polar Grizzly Black North America 7 86 64 Alaska 1 47 6 Norway Conflict Bear Kills by Group Type, (n=59) Management kills. Does not include research mortalities or bears that were euthanized for “humane” reasons U.S. Conflict Bear Kills by Group Type, (n=229) Location of U.S. Conflict Bear Kills, (n=225) Reason for Conflict Kills in U.S. Villages, 1999-2013 (n=74) Body Condition of U.S. Conflict Bears Killed in Villages, 1999-2013 (n=37) 62% were in below average body condition U.S. Conflict Bear Kills in Villages by Month, 1999-2013 (n=158) Polar Bear Attacks on People by Location Type, n=63 Attacks by Bears’ Body Condition (n=27) 63% of bears involved in attacks on humans were in below-average body condition, meaning they were skinny or thin 70% of bears involved in fatal attacks on humans were in below-average body condition What Led to Attacks on People? (n=59) *Includes predatory on human in tents and buildings (7), and predatory investigations (2) • 63% of polar bear attacks on people were predatory Predatory Attacks by Bear Sex/Age Class, n=35 Range-wide Attacks on People by Decade, 1960-2013 (n=59) U.S./Norway Natural Mortalities, 1989-2009 (n=46) Investments and Progress to Date, 2009-2014 Strategic Partnerships- Agencies Existing: Near Future? Your organization? Strategic Partnerships- NGOs Existing: Future: Your organization? 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 James Wilder, IUCN Polar Bear Specialist Group jamesmwilder@fs.fed.us 1-307-578-5158
