The Grizzly Bear is one of nature’s last keystone species that is contributing to the Western United states and Southwestern Canada. The Grizzly Bear is thought of as a vicious beast who kills people without intent. Grizzly Bears are actually important to the environment and ecosystem that they live in. This Bear is an intelligent animal, which serves a role of preserving a plant’s way of life. It creates soil disturbance which causes more nitrogen to be produced to generate more nutrients for plants.

The bear have evolved along time ago and now there is only eight species existing. They evolved from early canids during the late Oligocene and early Miocene, about 25 million years ago. The earliest ancestors where the Dormaalocyon Latouri. An intermediate ancestor was the short faced bear, very similar to the modern day bear. It lived through the pleistocene period. It grew to thirteen feet long and was a herbivore. The ancestors to the modern day bears lived in the same climate and ate the same things. The modern bear contrast from the ancestor because the ancestor was more skinny and was smaller, and it was more cat like. The eight species of bear that still exist. They are the Polar bear, Brown bear, American black bear, Asian

The grizzly sheds the thick part of their coat during the summer. The coat also protects the grizzly bear from insects or any types of bugs. The grizzly bears have a very large home range that they will roam through. The grizzly bear also spend hours of the day walking around, but that is common for grizzly bears. The wear in the temperate rainforest is sunny and sometimes rainy. When the grizzly bear needs to move quickly through their habitat it can be done so at a speed of 30 miles per hour. The mating season for grizzly bears start in mid-May it continues until the middle of July. Grizzly bears can live in the wild up to 30years. They can also die at the age of 25. Grizzly bears can be found in woodlands, forests, alpine meadows and prairies. They prefer to be around streams or rivers. Grizzly bears are mainly solitary, except for mothers and their cubs. Grizzly are known to meet up at a river or a stream. Grizzly bears are also very strong swimmers. Grizzly bears use sound, movement, and smells to communicate with each other. Grizzly bears happen to groan and moan to get each others attention. Grizzly bears also rub their bodies on trees so they scratch their self. Throughout the summer grizzlies build up fat by eating as much

Grizzly Bears - they are large bears that inhabit North America. Many people hunt them.

Black bears are the smallest North American bears however; they are the largest land mammal in New Jersey. Black bears evolved in thick forest and live in mixed hardwood forests, dense swamps and forested wetlands. They naturally like to eat fresh leaves, berries, fruits, nuts, roots, insects, bird eggs and small mammals. Black bears are generally solitary animals, with the exception of a sow and her cubs. They tend to be crepuscular, meaning they are most active shortly before sunrise and again after sunset. Black bears are typically not aggressive and tend to be wary of humans.

They have the whole package! And don’t think bears aren’t hostile, one slap in the face from a bear would kill a man. And don’t even get me started on polar bears, those things are monsters, they are the biggest species of bear and unlike most bears, they are pure carnivore, and if you cross one, and it sees you as food, consider yourself dead. The thing will chase you down until you give up and then rip you to shreds. Bears are not to be messed with. And they also have Moose and Caribou. And they can be dangerous if you mess with them, but another thing is Bison, there have been people who were gored by Bison before, and some have died. So i don’t think that they should be messed

Grizzly bears are a very unique type of bear. The bear has long sharp rounded claws. They also have large muscles in their back that help them dig. The bear has grizzled fur to help distinguish them from black bears. It is very important that we do everything to protect the Grizzly population.

The black bear is one of the most common bears in the U.S.A. Even though the black bear is one of the three smallest bears, it has great claws and amazing climbing ability. Experts estimate that about 80,000 black bears die each year in the U.S.A. This animal, the black bear, is threatened and should be saved.

Black bears in BC have a population that is 9 times that of the grizzlies, however, the results show that the grizzlies have inflicted 9.7 times more attacks on humans in the past 16 years. This goes to show that grizzly bears have a higher tendency to attack due to the natural factors and stresses that act on them cause them to be much more aggressive with less tolerance to threats (Herrero, Aspects of Evolution and Adaptation in American Black Bears (Ursus americanus Pallas) and Brown and Grizzly Bears (U. arctos Linne.) of North America n.d.). Many other papers such as Herrero’s study in both 1972 and 1985 showed the same results where grizzlies had higher rates of attacks compared to black bears in BC and so it clearly shows that there

In North America, the grizzly bear is a keystone species - not as a predator but as ecosystem engineers. They transfer nutrients from the oceanic ecosystem to the forest ecosystem. The first stage of the transfer

The Grizzly Bear, or Ursus arctos horribilus, is the second largest land based carnivore in all of North America. It has a life expectancy of twenty years, and the average male Grizzly Bear can reach an astounding three hundred fifty kilograms. While there are many bears that have the same brown coloring as the Grizzly, these are easily spotted due to their anatomy. The Grizzly Bear has a large hump or protrusion on its back, near the area of the shoulder blades. This mass of tissue and muscle helps to support the enormous front legs of the bear. Other distinctive characteristics of the Grizzly Bear include a concave snout, extremely long claws, and poor eyesight. Though dark brown is the most commonly viewed fur color, the Grizzly can be any shade from ivory to nearly black.

The Grizzly bears population has grown from about 200 in 1975 to approximately 600-1200 in the 18 million acers of the Greater Yellowstone ecosystem. (Yellowstone)

The principal cause of all the Human-Grizzly Bear conflict is human population growth. Human population has been increasing exponentially and humans are essentially invading natural environments in which animals like Grizzly Bears thrive. Habitat space for Grizzly bears is decreasing and they are competing for food and space with humans. Habitat destruction by humans leads to urbanization of natural habitats of animals; thus, leaving Grizzly bears to fend for themselves with scarce resources (Mace & Waller, 1998). Urbanization such as road development leads to fragmentation and increasing the chances Grizzly bear interaction with a human, this is because of transport and service corridors, particularly roads, are currently the prime form of humans to access to Grizzly bear range (MacHutchon and Proctor, 2015).

However, over 98 percent of grizzly bears have been eliminated to the number around 800 to 1,000 in the Lower 48 states. 01/06/2016 The Brewing Battle Over Grizzly Delisting and Trophy Hunting in the Yellowstone Ecosystem TheHuffingtonPost.com, Inc. (http://www.huffingtonpost.com/wayne-pacelle/the-brewing-battle-over-g_b_8923316.html) As such, it was hard to argue that grizzlies are thriving. Since European colonization, they have lost half of their continental habitat, and even in BC around a third of populations have either die out or are currently endangered. (Anna Taylor) Overkill - trophy hunting slams BC's Grizzly bears 7th February 2014 Ecologist /Resurgence Trust (http://www.theecologist.org/News/news_analysis/2271852/overkill_trophy_hunting_slams_bcs_grizzly_bears.html) Another point is that they have startling low reproductive rate among the terrestrial mammals. It takes ten years for a female grizzly to replace herself in the population, and she will stop breeding in her mid-to late 20s. Washington Department of Fish and Wildlife Grizzly (sponsor)/Biology & Behavior (title) (http://westernwildlife.org/grizzly-bear-outreach-project/biology-behavior/) A female can give birth to a maximum of 10 cubs over her lifetime, and half of the cubs will die within a year.(Ibid) What is more, grizzly bears play an important role in forest ecosystem as seed dispersers and nutrient providers. Generally they benefit the surroundings by transporting berry seed to enable them to geminate, or pile up their fresh manure as fertilizer. While they searching for tree roots or ground squirrels, they increased the amount of nitrogen through soil disturbance. (Ibid) As a predator, grizzlies can control prey population. They hunt vegetarian so that regional density of plants would not decline in large quantities. Grizzly bears can be said as a keystone species in their
