Preventing Extinction and World Change

For one, by 1980, wolves doubled to 50. By then it was apparent, ‘balance of nature’ seems to be the force that guides nature. This shows that wolves should be introduced because they are needed for balance

Wolves have always been a symbol of the wild, free in spirit and roamers of the land. These animals are considered majestic and protectors of the wilderness. They have always roamed the western United States, although their population has fluctuated over time. Over the past 10 years wolf reintroduction into Yellowstone National Park has been a controversial topic to those of the United States. As of 1995, wolves have been reintroduced into the park. This has come with some strong opposition and yet has prevailed. The future of the wolf in Yellowstone park is now looking bright, although not certain since there still are those who want them banished again.

For the first time in 70 years, the howl of the Grey Wolf is being heard throughout Yellowstone Park (Sanders, 2000). In January of 1995, 14 wolves from separate packs in Canada were trapped and transported to Yellowstone. Once in the park the wolves were placed in one acre acclimation pens. In total there were three pens scattered across the northern portion of Yellowstone: one a Crystal Creek, another at Rose Creek, and the last at Soda Butte. During the wolves time spent in these pens they were fed winter kill, or road kill. The packs that were formed in these pens were released in the winters of 1995-1996 and also again in 1996-1997 for a second release period (Sanders, 2000). In 1995 fourteen wolves were released and in 1996 seventeen were released. In 1997 there were 64 pups born and since 1995, 33 wolves have died in the Yellowstone area.

What do you think of wolves? Do you think they’re blood-thirsty killers, or do you think they are rather friendly animals? In the book, Never Cry Wolf, (1963) the author, Farley Mowat, writes about his excursion to the sub arctic Barren Lands of Canada to study how wolves act and how the community is being affected by the wolves. The people of Churchill lead Mowat to believe the wolves are something that they aren’t, which is a blood-thirsty killer. Mowat then uses the rhetorical strategy Pathos throughout the book to show you how he personifies the wolves and how fear is all in our minds.

While highly controversial, the reintroduction of wolves in Yellowstone Park has provided many beneficial ecological changes to the entire parks ecosystem. After a nearly 70 year absence, in January of 1995, 14 wolves from separate packs were captured in the Canadian Rockies and transported to Yellowstone National Park in the states of Wyoming, Montana and Idaho (Sanders par. 2).

“Restoring an ecologically complete ecosystem in Yellowstone requires the return of willows--and with them, beavers. There's a clear threshold for ecosystem recovery. Willow stands must be more than 6 feet tall, the scientists found. That height is important, says Marshall. Then willows are beyond the reach of browsing elk, and can serve as seed sources for new young willows. Once willows have returned, beavers will gnaw down a certain number of them to build dams. The dams will further slow stream flow, allowing yet more willows to grow. The results offer new insights on the role of wolf-driven trophic cascades in the Yellowstone ecosystem, says Hobbs. Trophic cascades like that in Yellowstone occur when predators--or the lack thereof--in an ecosystem change the abundance or alter traits of their prey, in turn affecting the next lower trophic level.” ("National Science Foundation", 2013)

Ed Yong makes very valid points on how the wolves of Yellowstone have impacted the overly populated elk herds. He has this to say about the herds; “Today the population stands at just over 6,000 down from 19,000 in the elk’s wolf-free heyday,” (ll57). This might seem like a terrible drop in the elk’s numbers, but it is actually a good thing. Yong tells us, “The large deer had run amok in the wolf-free decades, causing serious damage to the park’s trees,” (ll5-6). So in reality, while there are far less elk now, the trees can start to build back up again.

I am taking a class called global environmental issues and heard about how reintroduction of wolves has had very positive impact in Yellowstone, but we did not go much deeper than just stating so.

The state legislature has favored the ranching industry above ecology and continues to do so. Public polls “conducted by Boise State indicate that the overwhelming majority of Idahoans (nearly 70 percent) support wolf restoration” (Laverty, par. 4) and the legislature is seeking to remedy this by re-educating the public with “a balanced view of the impact of wolves on big game species, those sectors of the economy dependent upon sport hunting, livestock, domestic animals, and humans” (State, 3). Furthermore, the “cost of wolf reintroduction will be presented as a part of any public education program including direct and indirect costs” (State, 3).

Farmers, ranchers, and government agents have been contributors to this decline by poisoning wolves and over trapping (National Wildlife Federation, 1996-2015). From January 1, 2015- March 31, 2015 there have been a total of 13 wolf deaths in the state of Minnesota. A total of 3 were unknown, 3 incidental, 1 was hit by a vehicle, 1 natural death, 2 under investigation, and 3 were illegal that included 1 illegal shooting and 2 illegal snares. (Minnesota Department of Natural Resources, 2015) Humans have not only been the factor of decline in wolf population, but the decline in prey (bison, elk, white-tailed deer, moose, caribou, and beaver) has decreased wolf numbers as well. Being the white-tailed deer population has increased the wolf population is back on the rise. (U.S. Fish and Wildlife Services, 2015, April 23) These factors are essential when it comes to determining the problem behind a decline in a specie population. We not only need to look at one factor, but a wide range of issues that can contribute to this

These results supported previous research that wolves have density and/or trait meditated effects on white tailed deer. They also provide experimental and manipulated support for previous experiments suggesting that wolves generate trophic cascades affecting sapling and vegetation growth in various regions, as well as the Great Lakes forest area.

The authors eventually discuss the Yellowstone experiment and share their research results. They focus on the northern winter range which is a large mountain terrain that mostly occurs within the northeastern area of Yellowstone National Park. Here, the authors took into consideration annual precipitation and even the average depth of snowpacks. After looking to historical data for the northern range of Yellowstone, Ripple and Beschta evaluated recruitment on aspen and cottonwood over the last two centuries and found that the extirpation of wolves allowed elk to browse unimpeded during winter months.

For those languages which have no written form, when the language dies off, so does the accumulated knowledge and history of the culture. Sadly, indigenous languages around the world are dying off at an alarming rate. It is estimated that nearly half of the languages spoken today are likely to die off within the next century if steps are not taken to preserve those which still exist.

Since the beginning of life itself, some species have lived and prospered while other species have gone extinct never to be seen again by mankind. Because of this, some would claim that extinction is natural and not significantly problematic to the world that we live in. Others, however, understand that due to climate change, habitat loss, and poaching, more and more species are becoming endangered which leads to a chain reaction that can be devastating to ecosystems. Species such as the Chinook salmon, gorillas, tropical sharks, and polar bears are all directly affected by climate change, species such as northern spotted owls, Sumatran tigers, and lemurs are greatly harmed due to habitat loss, and species such as the sea turtle, Javan rhinoceros, African elephant, and the Red-Fronted Macaw are all affected by poaching driving them all closer and closer to becoming extinct.
