The Characteristics Of Grizzly Glies

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

Grizzly Bears aggressive predators and have incredible strength. They are usually twice the size of a black bear. Male grizzly weighs up between 400 to about 900 pounds. Female grizzly weighs up to about 200 to about 500 pounds. They can run up to bout 40 miles per hour. They can stand on their hind legs giving them advantaged to defend or fight another predator. They came from Asia and little bit from Europe. They can live up to over 20 years. Their hump on their back allows them to run fast and be powerful when it comes to hunting their

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 Bear is a Keystone species. A keystone species is the center block, of which an ecosystem largely relies on. The Grizzly Bear lives in places such as alpine slopes, avalanche shoots and lower elevation wetlands.

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)

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

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

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.

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

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.

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 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).

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.

Bears only become aggressive when they feel threatened. Other than this situation, it is very rare for bears to intentionally attack people. If people were proverly educated on bear safety and how to not provoke them, then there would be a decrease in the amount of bear attacks. Countless bear attacks in New Jersey happen because of hikers invading the bear territory and in some way provoking them. A good solutions is for the state of New Jersey to make trails that avoid bear territories. This way bears and humans have little interaction and conflicts.

Grizz, Panda and Ice Bear are three siblings living in the Bay Area, hanging together and attempting to have some good times as they discover their way in life. They simply happen to be bears, is all.
