grizzly bears prefered habitat is deserted rivers, wild mountains, and thick and dense forest. Grizzly bears are majestic symbols of the wild. Bears live in and use a variety of habitat types, playing important roles in each one. This makes them an “umbrella species,” meaning that when we protect them and their habitat we also protect many species. Grizzly bears can also help ecosystems by distributing seeds and nutrients through their scat, and occasionally regulating ungulate populations.
they are at the top of the food chain of the grassland plants and animals. Grizzly bears are powerful, top-of-the-food-chain predators, yet much of their diet consists of nuts, berries, fruit, leaves, and roots. Bears also

In recent years, chum salmon returns have seriously decreased in the Great Bear Rainforest. In the fall of 2009, local people reported that a majority of bears did not return to fall fishing grounds. There is major concern that grizzly bears starved in their dens over the previous winter due to lack of salmon in the feeding season before that.
The characteristics of the grizzly bear as a top predator also make it highly vulnerable to threats. Although it is an omnivore, because it relies heavily on salmon to make it through the winter, it is vulnerable to anything that impacts on salmon runs. It needs wide-ranging habitat and is slow to reproduce. As such, grizzly bears are considered not just a key species but also an ‘umbrella species’ because the protection of their habitats will result in an ‘umbrella of protection’ for a wide range of other species. The protected areas that have been set aside in the Great Bear Rainforest are not enough to sustain healthy populations of grizzly bear so it requires additional habitat set aside from logging. Trophy hunting of grizzly bears also continues to place their population at
Grizzly bears live in a variety of environments .All of which includes dense forests, subalpine meadows, open plains and arctic tundra . In the past though, they could be found from Alaska to Mexico, and from California to Ohio. Though Nowadays there are efforts trying to make it so grizzly bears can make a comeback and the wild, and all of their efforts are proving to be working, there are 4 times as many grizzlies in the wild as there were in 1975, at
Now even though these bears help the environment so will other bears. The Grizzlies are just another species of the many species of bears why are these bears more important than other bears. As we find from the GNWT: “Grizzly Bears in the NWT occur primarily in open alpine or tundra habitats, but they can also be found in forested areas. They have large home ranges relative to most other bear species. On average, a male’s range can exte...
The habitat is also made up of trees with nuts and bushes with berries. Black Bears are omnivores so they eat these along with other small animals. They are opportunist when it comes to food. Mostly bears eat vegetation during the spring but they will eat mainly anything they encounter. During the summer the bears eat salmon out of the rivers if they can catch it. If they can’t catch any they mainly survive off of berries, mainly blueberries, ants, grubs, and other insects. In the fall their diet starts to shift and they start to save up food for winter. They are also known to eat newborn moose calves during the winter when food is scarce.

In this research paper, I will address the changes that occurred within the ecosystem of Yellowstone National Park since the reintroduction of the grey wolves. The paper will consist of four sections; the first section will include the history behind the extirpation and subsequent reintroduction of the gray wolf in Northern America. The second section will explore the political controversy that surrounds the reintroduction of the gray wolf in Yellowstone. The third section will contain discuss the gray wolf and its impact on the ecosystem of Yellowstone. I will conclude my essay by explaining how the gray wolves act as climate change buffers in Yellowstone amidst global warming.
Although they are now rare, grizzly bears inhabit the dense forest of Montana’s Rocky Mountains. Grizzlies grow as tall as eight feet and can weigh up than 1,000 pounds, yet they can move as fast as a horse. There are six national grizzly recovery zones, and three are in Montana. They are Cabinet-Yaak, Northern Continental Divided, and Yellowstone (Av2 books).
The grizzly bear trophy hunt is an issue regarding the citizens of Canada who immorally hunt and kill grizzly bears for pride, thrill, and trophy. Many people question whether this is morally acceptable as hunters kill without a conscience. Grizzly bears are vital to Canada’s environment as they are essential to maintaining a healthy ecosystem. As keystone species, they regulate prey, disperse seeds of plants,and aerate soil to maintaining forest health. Due to the vulnerability and over-hunting of grizzly bears, Pacific Wild and many other non-profit organizations, are working to protect wildlife in British Columbia, especially the grizzly bear habitat.
Many may not have known; but, Grizzlies are not picky eaters. Grizzlies are opportunistic eaters, and will eat whatever is available to them at the time. This makes it easy for them to find food, because of the variety of foods they can eat.They are also omnivorous, meaning; they eat both plants and animals. A grizzly bear may eat plants; including: grass, roots, tubers, seeds, moths, wild berries, insects, fungi, nuts and other plants. They also will eat animals such as: small rodents, elk, bison, moose, carrion (decaying flesh of dead animals), salmon, trout, bass, crabs, and others. A misconception people tend to have is that the grizzly bear is stingy with its food and doesn’t like to be around other bears while eating. However, when there is much food in the area; the grizzly bear doesn’t mind eating with other bears. Although, once the food source has gone down; the grizzlie’s will go their separate ways to search for more food. A specific food that grizzly bears like to eat is salmon. Many times the salmon will return to the river, they were born in, and make their way upstream. Fishing for salmon in late summer is the best way for grizzlies get the food they can store up as fat. During this time the grizzly bears gorge themselves on the salmon, eating about 25 fish per day to put on extra weight. When there are many fish for the Grizzlies to feed on they’ll eat about
Good literary text can communicate messages more powerfully than good informative text. 2 different texts, Moon Bear Rescue by Kim Dale, and the brochure Southern Asian Moon Bears, are chosen to represent in the argument between literary and informative. Both books are similarly capable of delivering a message, but which is more powerful? Informative clearly states the facts and provide consecutive information; raises awareness for the objective, i.e. Moon Bears, whereas the literary tends to tell more of a story, perhaps information, adapted to entertain the reader, and sometimes, to educate. Because of this, I feel that the literary is much more capable of providing a powerful message, mostly informative text lacks the friendly and heart-warming story that the literary text provides.
Until now, there is not a certain answer to how many grizzly bears are left in British Columbia. With approximation ranging from as low as 6,000 by individual biologists to as high as 15,000 by the B.C government, grizzly bear populations are therefore controversial. The reason why official estimates cannot be trusted is that the method used is suspicious since the government only applies a predictive model based on ground surveys conducted in only a limited number of areas. One of the independent scientists, Kyle Artelle, suggests that “more bears were being killed than government quotas allowed.” (thenarwhal) Serious situations, such as extinction, could occur on this species if trophy hunt in addition to other dire scenarios such as declining stocks of salmon along coasts and danger of road and railway accidents proceeds. Even though it is nearly impossible to eliminate all harmful causes of the depopulation for grizzly bear, the prohibition of trophy hunt can be easily taken into action to mitigate the negative trend. Additionally, grizzly bears are being an integral part of the ecosystem where they live. In case the grizzly bears die out, the ecosystem will become chaos. (pacificwild) For example, the speed of seed dispersal of many plants and berries will be reduced, the ocean-derived nutrients will cease to be transferred into inland to make
The Grizzly bear are really interesting. Grizzly bears are dangerous and they eat a lot of thing but there diets are berries,roots,seeds,dead animals,fish,elk,insects,and other foods that they find. Grizzly bears are mammals and they are unpredictable and really dangerous. Grizzly bears live in many different areas they live in california,Ohio,Wyoming and in western Canada. But bears are also found in open Plains dense forest.
First, I chose a grizzly bear because I am more familiar with it and would like to learn more about them.This animal is big,brown,and furry.
National Parks are the cornerstone of every country because it preserves the rich cultural and natural resources of a nation, such as Yellowstone in the United States of America. Yellowstone National Park is the World’s First National Park which brings millions of attraction each year, it is larger than Rhode Island and Delaware combine and have over a thousand species of plants and animal (Yellowstone Media). However, a very important type of species has been missing in Yellowstone National Park for a very long time. Wolves, which got reintroduce back into Yellowstone National Park, should stay there because without them the ecosystem would be out of balance.
Studies show that wolves play a significant role in maintaining healthy ecosystems, and could even help stave off some of the effects of climate change. They help keep large animal herd populations in check, which can benefit numerous other plan...
The Arctic region is home to a variety of valuable animals and plants, including polar bear, seal, and so on. The ecosystem of the Arctic region is fragile because these animals are evolved to live in extreme conditions. With the climate change, many animals are endangered. Ice is the habitat of polar animals because they have to rely on sea ices for resting, food, and reproduction. With the climate change and the decrease of sea ice, the number of polar animals is decreasing and their health is threatened. For example, the average weight of female polar bears in 1980 was about 650 pounds, but the number reduced to about 500 pounds in 2004 (Djoghlaf 15). The earlier breakup and later condensation of sea ice shortens the hunting season of polar bears. Polar bears mainly feed on seals that indwell icy land. The melting ice reduces the number of seals and food intake of polar bears. In addition, polar bears are used to living in ice caves. The rising temperature causes the collapse of ice caves, which can kill baby bears. The climate change is negatively affecting the biodiversity in the region and will definitely harm the ecosystem
