Canadian Lynx Synthesis

1616 Words7 Pages

INTRODUCTION The majestic, healthy Canadian Lynx (Lynx canadensis) population still roams much of Canada and Alaska. But in 1973, the Lynx was put on the Endangered Species list for being hunted and poisoned in the United States. ( U.S. Fish and Wildlife Service) The U.S. Fish and Wildlife has listed the Lynx as threatened in Colorado. (IUNC Red List, 2015). The reintroduction of the Canadian Lynx (Lynx canadensis) back into Colorado is important because the Lynx has the most southern historical natural population in the United States. (U.S. Fish and Wildlife Service) Not being able to keep that habitat border for this animal would be an unpleasant poke in the eye for the state that is suppose to be on the rise in environmental and ecological …show more content…

Modeling is an important tool to test if the reintroduced animal has a chance to succeed and thrive in an area where it vanished. Factors that we now know can be but into that model, such as the relationship that the lynx has with its keystone prey, the Snowshoe Hare (Lepus americanus). Prey abundance is an important factor in the predator – prey relationship of the lynx and hare. Studies have shown that for the lynx to succeed there needs to be a hare population of 1.1 to 1.8 hares (Steury, 2002) The next set of studies that went into the success of the lynx was the study that took into account that the lynxes chooses a habitat that best suits its prey. The best type of habitat for Snowshoe Hare are the mature spruce-fir forests. (Ivan, 2012 Density ShH) The lynxes preferred habitat coincides with the hares, or very close to, mixed spruce-fir, aspen forests. (Ivan, 2010 LH) By first finding other areas in Canada and Alaska where the Canadian Lynx (Lynx canadensis) and its keystone prey co-habitat harmoniously, the modeling fit quite well to reintroduce the lynx back into the San Juan Mountains. Habitat is an important focus on keeping the lynx in an area where it can be thrive but there has to be another focus too. This animal has a large home-range and also needs to have corridors set up for breeding purposes. The study of Predicted Habitat in Colorado, Ivan 2011, tried to predict the habitat north of the San Juan Mountains to determined if the Lynx would be able to not only have a corridor to the other northern states but also to have breeding sites. The determination was that they could not with any accuracy predict that the Canadian Lynx (Lynx canadensis) could use the land due to the landscape being so different than the Southern areas. Also the lack of information on the vegetation for the Snowshoe Hare (Lepus americanus) is critical. The

To where have all the black-footed ferrets disappeared? The black-footed ferrets have been endangered since 1967 in the southwestern corner of North Dakota due to loss of habitat and a depletion of their prime food source.

Introduction The Ochotona princeps, better known as the American Pika or Pika, is a small, little creature that is becoming one of the upcoming symbols of global warming ("American Pika"). The O. princeps are beginning to suffer from global climate changes to their habitat in the Western mountains of the United States ("American Pika"). In an experiment by Anna D. Chalfoun, Daniel F. Doak, and Leah H. Yandow, the effects of habitat and climate change on the Pika abundance in two mountain ranges is tested to see how global warming is impacting the species (Chalfoun. Doak, and Yandow).

Summary Of Arctic National Wildlife Refuge By Jimmy Carter

412 Words | 2 Pages

The author writes of personal experiences and thoughts to show the importance of the Wildlife refuge in more than just a factual standpoint. Carter notes how disappointed and saddened he would be if the Refuge was destroyed, “Standing on the coastal plain, I was saddened to think of the tragedy that might occur if this great wilderness was consumed by a web of roads and pipelines, drilling rigs and industrial facilities.” This adds power to the argument furthermore, as he demonstrates his attachment to the area and animals living there, “During bright July days, we walked along ancient caribou trails and studied the brilliant mosaic of wildflowers, mosses, and lichens that hugged the tundra… we watched muskox, those shaggy survivors of the Ice Age, lumber along braided rivers that meander toward the Beaufort Sea.” This then gives us a connection to the Refuge so we are more affected to the possible outcome of it being built into an industrial

Black Footed Ferret Case Study

Throughout the past several decades, the black footed ferret (mustela nigripes) remains at the near top of the endangered species list. These small mammals are one of the most endangered species in North America. The black footed ferret has little visibility compared to other endangered species. With a population of only 370, the black footed ferret’s chances of survival appear slim. Total elimination of the black footed ferret would negatively impact other species in its ecosystem.

Comparison Of The United States Fish And Wildlife Service (HCP) And Montana

1104 Words | 5 Pages

The United States Fish & Wildlife Service (USFWS) and the Montana (MT) Department of Natural Resources and Conservation (DNRC) developed a multispecies habitat conservation plan (HCP) to address the potential take of federally listed species on forested state trust lands (USFWS & DNRC, 2010). The HCP was prepared in order to comply with Section 10 of the United States (U.S.) Endangered Species Act (ESA), which allows for the incidental take of a threatened or endangered species by private or non-federal government agencies during lawful activities (USFWS, 1996). The HCP was developed to protect five aquatic and terrestrial species; the bull trout (Salvelinus confluentus), the westslope cutthroat trout (Oncorhynchus clarkii lewisi), redband trout (Oncorhynchus mykiss gairdneri), the grizzly bear (Ursus arctos horribilis), and the Canada lynx (Lynx canadensis) (USFWS & DNRC,

Persuasive Essay On Gray Wolves

1237 Words | 5 Pages

Issue Whether or not to list the gray wolf in Wyoming on the endangered species list has been and still is a debated topic because of the species close proximity to the Greater Yellowstone Ecosystem (Fig.1). The government of the State of Wyoming, one of the stakeholders in the debate, believes that state legislation successfully protects the species from being endangered without federal intervention. Contradictorily, the Center for Biological Diversity, Defenders of Wildlife, Fund for Animals, Humane Society of the United States, Natural Resources Defense Council, and Sierra Club (“Defenders of Wildlife, et al.”), all opposing stakeholders in the debate, believe the state legislation threatens the Wyoming population of gray wolves and needs federal intervention. The United States Fish and Wildlife Service (“USFWS”) has changed sides multiple times on the matter but is aiming to remove the species from

Essay On Anti Wolf Reintroduction

Sixty years after the extirpation of wolves in the Northern Rockies and Great Plains of America, biologist and ecologist in Yellowstone National Park reintroduced wolves into a declining ecosystem that once thrived during their presence. The reintroduction brought immense controversy into the West and continues to stir outrage among anti-wolf groups. These anti-wolf supporters argue wolves are ruthless predators that cause destruction to natural environments and livestock. Conversely wolf advocates and scientists suggest that wolves are a keystone species that are essential to the natural regulation of our Western ecosystems. Although pro and anti-wolf advocates can agree that wolves have an effect on livestock, ungulate populations and ecosystems,

Pros And Cons Of The Endangered Species Act

According to research the ESA has been very successful in helping to help these species come back. “The Endangered Species Act has been successful in increasing the number of species that are considered as being on the brink of extinction. After all, this is the largest pro of this law and also its main goal”("14 Compelling"). This is important because it is the largest argument for this topic and also because it helps species of animals that are dying come back and start to thrive again. The endangered species act must be kept to keep the dying and endangered
