The walrus depends on sea ice as a floating nursery for their young. The species that call the refuge home have been protected from the risks of unsustainable development for decades, but now the US government is moving forward with plans to open the coastal plain of the Arctic Refuge to allow for oil and gas drilling. The formation of countless, new deer trails after the disappearance of the wolves, shows that the ecosystem has lost its balance and is overpopulated with deer. Luckily, current population is still large and Arctic wolf is not on the list of endangered species. To report a Copyright Violation, please follow Section 17 in the Terms of Use. Evidence on Endangerment: The last estimate of the walrus population was 250,000 in 1990. Walrus feed on the ocean floor in the shallow waters of the continental shelf where the sea ice contains food. Sarah, amazing site, is there a little more on global warming on this page aside from the picture? Evidence of Endangerment: There is no graph evidence available, however there has been data showing that cubs are of various sizes in the West island of Iceland, suggesting that food supplies are unstable. The Arctic wolf doesn’t have a subspecies, but it is a close relative of the grey wolf. Arctic Hares and Muskox (some of their prey) have lost their food sources due to global warming. In parallel, the Arctic Tundra is going through a period of imbalance, where climate change is causing weather fluctuations, which inhibit caribou and musk oxen, the main food sources of arctic wolves, from finding food. Arctic wolves are also affected by climate change as well. Effects on Biome: The Arctic wolf is on the third trophic level of the food chain in the polar ice region. Oil fields, such as the one in Prudhoe Bay, disturb wolves in their natural habitats, and according to National Geographic, "exploration of oil, gas, and minerals and construction of pipelines and roads can cause physical disturbances and habitat fragmentation." With fewer of these animals to eat, Arctic Wolves have smaller food sources, which has led to their endangerment. Arctic wolves are also affected by climate change as well.

Because of the greenhouse gas effect, which traps heat in our atmosphere, the entire planet has increased in temperature, which threatens all of us, but especially those in arctic climates. Please contact Adobe Support. The Arctic wolf is of the least concern when it comes to being endangered but it does face threats of endangerment. ( Log Out /  Leopold uses the imagery of the dying mountain to show his audience that without the natural balance of wolves as predators, the other animals will grow without boundaries and destroy their habitat. Change ), You are commenting using your Google account. In 1997, there was a decline in the Arctic wolf population and its prey, muskoxen (Ovibos moschatus) and Arctic hares (Lepus arcticus). ( Log Out /  These animals were frequently on a target of European commercial hunters in the past. "Endangered Species: The Arctic Wolf," The Arctic Wolf Blog. https://thearcticwolfblog.wordpress.com/why-endangered/. As the sea ice melts, the walrus population is forced inland for new habitat which creates overcrowding and deadly stampedes. International Union for Conservation of Nature, or the IUCN, deemed arctic wolves as endangered in the Endangered Species Act of 1986. They are now listed as 'least concern' which is the lowest level of... See full answer below. Evidence of Endangerment: The food pyramid shows the level the Arctic wolf is at in the food chain. Cause and effect of global warming; the main threat to arctic wolves. As the population of wolves decreases, there will be fewer predators of caribou and musk oxen, resulting in their rapid growth. Big companies that develop in the arctic tundra with mines, roads, and pipelines are also hurting the arctic wolves and other animals in their environment. However, that doesn’t mean we’re not at fault. Arctic Hares and Muskox (some of their prey) have lost their food sources due to global warming. SIC projections were obtained from a. subset of atmosphere-ocean general circulation models. WHY. The reason for their endangerment is Global Warming. However, when this balance is disrupted in the story, due to the hunting of wolves, Leopold "[watches] the face of many a newly wolfless mountain, and [sees] the south-facing slopes wrinkle with a maze of new deer trails" (Leopold 8). They are secondary consumers. The Arctic National Wildlife Refuge is located in one of the largest remaining natural areas on the planet: Alaska. In order to do so, carbon taxes need to go into effect to help reduce the significant amounts of carbon being released into the atmosphere which is the primary contributor to climate change and the melting of the ice.

Currently, wolves have a depleting source of prey, which has resulted in a decrease in the arctic wolf population, but once the wolves are very scarce, the populations of caribou and musk oxen will increase rapidly. Projected continent-wide declines of the emperor penguin under climate change. Left: Prudhoe Bay, Alaska oil field; Right: Bristol Bay Pebble Mine. It’s biggest threat, however, is … In fact, 225,000 WWF activists prevented new oil drilling in America's Arctic Tundra, and according to WWF, this ban on new drilling will last for the next five years. The Arctic wolf population was mainly in the central part of the range, which made them vulnerable to the Danish and Norwegian hunters, which exterminated the population with the use of poison. denning areas and movement corridors, seasonal feeding areas and times, and key resting areas during the ice free period. © Adobe Systems Incorporated. Change ), You are commenting using your Facebook account. Our impact on the wolves is very real and very big. ( Log Out /  All rights reserved. The Pebble Mine in Alaska is the largest open-pit mine in North America, and WWF says that toxic waste could contaminate the bay, affecting tons of species, not just arctic wolves. The WCC is an organization that focuses on providing wolves with comfortable habitats and spreading awareness about the impact of climate change on wolves and their ecosystem. The US Geological Survey and the Russian Knipovich Research Institute are teaming up to determine the walrus population. Arctic wolves are not actually listed as endangered unlike other wolves.
