DISTRIBUTION AND HABITAT • Polar bears are native to the Arctic
Circle.
• Their distribution is mostly centred in
the Arctic but a small population can
be found in James Bay, Canada.
• Their habitat are areas where sea
ice covering the waters over
the continental shelf known as “The
Arctic Ring of Life”

THREATS• Loss of sea ice habitat due to global
warming.
• Industrial development in the Arctic.
• Unsustainable hunting in few places.

ORIGINAL CONDITION
CURRENT CONDITION• Sea ice is projected to disappear in the summer within a
generation.
• Migration following the movements of the ice pack.
• Move onto land for summer and disperse over ice for the
winter.
• IUCN added the polar bear to its Red List of the world’s
most imperiled animals.
• Found throughout the circumpolar Arctic.
• Live majority of their lives on sea ice.
• Provides to hunt, live, breed and in some cases
create maternal dens.

POPULATION OF POLAR BEAR• World Polar Bear - 20,000 to
25,000
• Ratio of males to females is
approximately 1:1
• Currently : May not have
increased
• More recently : Declining

CONSERVATION STATUS• Polar Bears are currently protected under
CITES Appendix II, which allows regulated
international commercial trade.
• At their 2014 meeting, the IUCN Polar Bear
Specialist Group reported that of the 19
subpopulation of polar bears
Are Declining Are Stable
Is Increasing Are Data Deficient

ECONOMIC IMPORTANCE OF POLAR BEAR
• Polar bear genes could provide clues to help humans deal with health problems
caused by high-fat diets.
• Individuals are willing to pay a premium to hunt or view the polar bear.
• Fur is used to make trousers and outer footwear.
• The heart is dried and powdered for medicinal purpose.
• The fat is used in food and as a fuel for lighting homes

ECOLOGICAL IMPORTANCE OF POLAR BEAR
• A keystone species in the biologically rich Arctic.
• An apex predator within it’s range.
• Important indicator of the Arctic ecosystem health.
• Regulates density and reproductive success of Ringed
seals.

CONSERVATION EFFORT TO SAVE POLAR BEAR
• Create Safer Communities
Keeping polar bears separate from people
is better for both.
WWF has responded with a variety of
locally-led initiatives to help reduce conflict.
Russia, Canada, and Greenland, WWF
supported polar bear patrols deter
bears before they get into populated areas.

• Protecting Critical Habitat WWF recognizes the urgency of protecting habitat for polar bears Not all Arctic areas are created equal for polar bears
• Reducing Industrial Activity WWF accepts that it is unreasonable to designate the whole Arctic as a place
of no industrial activity. WWF’s goal is to ensure that whatever development takes place do not
damage wildlife ecosystems.
