Environment Canada - Nature - Conservation of Polar Bears

Environment Canada - Nature - Conservation of Polar Bears | science conservation | Scoop.it
Canada is home to more than two-thirds of world's polar bear population and so, has a unique conservation responsibility to protect these iconic creatures.
AndrewLi's insight:

-Canada is home to approximately 16 000 of the estimated 20 000–25 000 polar bears in the global polar regions.

 

-Approximately 2% of the Canadian polar bear population enters international trade (300 bears annually),

 

-The current global population size is estimated at 20 000–25 000 polar bears. The polar bear does not have a small wild population, it does not have a restricted area of distribution and no marked decline has been observed.

 

-Polar bear also do not meet the biological criteria to be listed in Appendix I. To be listed, a species must be “threatened with extinction..

 

-The polar bear was listed as a species of Special Concern in November 2011 under the Species at Risk Act (SARA), which is strong domestic legislation to conserve and protect wildlife in Canada.

 

-Canada is home to two thirds of the global polar bear population and is committed to the conservation of this incredible species. In Canada, polar bears are protected through a collaborative approach that is shared with provinces, territories and regional wildlife management boards.

At the top of the food chain, polar bears have an important role in the marine environment. Learn how WWF is fighting the biggest threat to polar bears’ survival: loss of sea ice.
AndrewLi's insight:

-They have a thick layer of body fat and a water-repellant coat that insulates them from the cold air and water.

 

-The total polar bear population is divided into 19 units or subpopulations.

 

-Polar bears are at the top of the food chain and have an important role in the overall health of the marine environment.

 

-Polar bears depend on sea ice for their existence and are directly impacted by climate change—serving as important indicator species.

 

-As climate change forces polar bears to spend longer time onshore, they come in contact more often with Arctic coastal communities and others working in the Arctic.

 

-Because of ongoing and potential loss of their sea ice habitat resulting from climate change, polar bears were listed as a threatened species in the U.S.

AndrewLi's insight:

-The major threat to the western Hudson Bay polar bear population is global warming. The increase in temperature leads to changes in the sea ice, which is the preferred habitat of polar bears.

 

-Conservation staff will also respond to requests made by the public to areas outside of the zone if a polar bear is considered to be a threat.

 

-protect people and property from the dangers posed by the presence of polar bears,To ensure the conservation of polar bears and avoid undue harassment and killing of bears,  prevent polar bears in the Churchill area from becoming conditioned to scavenging for food or developing other problem behaviours. protect Manitoba Conservation staff who work in the Polar Bear Alert Program

 

- When a bear is captured, it is moved into a specially built holding compound called the Polar Bear Holding Facility.

 

- Changes in the ice which affect the seal population or the bear's ability to kill seals would adversely affect the bear population.

 

-As autumn approaches, they begin to move northward along the coast and congregate where the first winter ice forms. This annual movement brings many bears into the town of Churchill each year.
