  • “Return of the wolves to Yellowstone National Park, USA: A model of ecosystem restoration”- Article published in 2004.┬áThis paper documents the success of the wolf restoration project in Yellowstone National Park. Humans have stimulated re-growth and rejuvenation of a healthy ecological system, something that is not typical of human nature. The role of federal policy in shaping processes leading up to wolf reintroduction is discussed as well as controversy surrounding the program. The article documents the ecological impacts and observed effects resulting from the reintroduction, like tree and river survival and small animal population increases, like the beaver.

  • “Grey Wolves Left Out in the Cold”- Journal Article published in 2013. Wolf populations are forcing biologists and policy-makers to re-examine the definition of “endangered species.” Wolf populations around the western Great Lakes and northern Rocky Mountains have warranted their population to remove them from the endangered species list. The US Fish and Wildlife Service was playing with the idea to remove all wolf populations from the list, something that the American public did not take with a smile. Groups have formed to protest and keep them on the list, while some biologists claim that they are non longer in risk of becoming extinct and can be removed from the list. The controversy is still on-going.

  • The first source connects to my thesis by providing more evidence about the ecosystem that the wolves are involved with. The second source connects by showing how the public reacts to government changes with the wolves at the park. The issues about the wolves in the park are still going on today.
