- Title: Aspen, elk and fire in the Rocky Mountain national parks of North America
- Journal: Wildlife Society Bulletin
- Authors: C. A. White, C. E. Olmstead, and C. E. Kay
- Date: 1998
- Summary: White et al. comparatively studied the research literature and historic photographs to evaluate aspen (Populus tremuloides) change over time in 6 Rocky Mountain national parks in Canada and the United States: Jasper, Banff, Yoho, Kootenay, Yellowstone, and Rocky Mountain. Across all parks, aspen has consistent responses to increased browsing by ungulates and decreased frequency of fire. Trees are intermediate to mature in age, and elk (Cervus elaphus) browse off the new suckers before they reach 2 m in height. Fire, combined with browsing, has hinde ...

- Title: Viewpoint: Ungulate herbivory, willows, and political ecology in Yellowstone
- Journal: Journal of Range Management
- Authors: C. E. Kay
- Date: 1997
- Summary: Some researches state that willows (Salix spp.) on Yellowstone National Park's northern range have declined because of climatic change, fire suppression, reduced chemical defenses, or other natural factors. However, these claims are not supported by available data. Instead, the evidence suggests that willows have declined due to repeated browsing by an unnaturally large elk (Cervus elaphus) population. Prior to park establishment, predation by Native Americans kept ungulates from impacting Yellowstone's plant communities. By established standards, ...
