The polar bear is a large bear species. It is endemic to the Arctic regions of the Northern Hemisphere. Due to climate change habitat of polar bear is undergoing significant change. The reduction in sea ice range as well as duration is impacting their ability to hunt and travel. It is also posing challenges to their survival. It is very important to take conservation efforts and measures to reduce climate change for the long term survival of these species.
Let’s discuss some information about the habitat of polar bears:
Arctic Regions: Polar bears are primarily found in the Arctic regions surrounding the North Pole, including countries such as
- Canada
- Russia
- United States (Alaska)
- Greenland
- Norway
They inhabit areas where sea ice is abundant as they rely on it for hunting and traveling purposes. These countries have cold temperatures as well as enormous stretches of sea ice.
Sea Ice: Polar bear’s survival rate is highly dependent on sea ice. They spend a major portion of their lives on the frozen sea ice, which is used as a platform for various activities such as
- Hunting
- Traveling
- Mating
- Denning
Sea ice provides access to their primary prey, seals, which they rely on for their diet.
Pack Ice: Polar bears are adapted to living on pack ice. This type of sea ice forms and breaks up with the changing seasons. They are skilled swimmers and have the ability to travel long distances between icebergs, using their powerful forelimbs to propel themselves through the water.
Coastal Areas: When sea ice retreats during the summer months, polar bears may move to coastal areas. These areas provides alternative food sources like marine mammals for example
- Walrus
- Beluga
- Whales
- Bearded seals
Coastal regions also provide land for the bears to rest and occasionally dig snow dens.
Arctic Tundra: Polar bears are known to inhabit the Arctic tundra, particularly areas near the coast. The tundra consists of vast treeless areas of frozen soil which are characterized by
- Low-growing vegetation,
- Permafrost
- Harsh weather conditions
Snow Dens: Female polar bears seek out snow dens in the winter months to give birth and raise their cubs. These dens are usually built in snowdrifts or dug into the snow and provide protection as well as insulated environment for the vulnerable cubs.
Open Water: Polar bears require access to open water for hunting and to swim between icecaps. They are strong swimmers and can travel long distances in water. During the summer months, polar bears found near the coastal areas or on islands as they are waiting for the ice to return.
Terrestrial Habitat: Polar bears also have the ability to spend some time on land. They may come ashore in the summer as the sea ice melts completely. They also use these areas for denning purposes. During these times, they may inhabit
- coastal areas,
- tundra regions,
- islands
They can be found in areas with suitable food sources such as carcasses or bird colonies.
