Eleven- or twelve-year old bulls often grow the heaviest antlers; after that age, the size of antlers generally diminishes. Because of their high densities, elk that are fed in winter have sustained high levels of brucellosis; winter feeding on the northern range stopped more than 50 years ago.

Learn about Yellowstone's Chronic Wasting Disease Surveillance Plan. Jr. 2003. Jarvis noted that more broadly, the new picture of the Yellowstone elk migrations provided by the study's comprehensive mapping effort "clearly demonstrate the need to think and operate at the landscape scale." The reappearance of carnivores on the landscape has had significant and sometimes unexpected impacts on the resident grazers and their habitat. Forage was cut and stockpiled to feed livestock, forcing native grazers to starve or raid haystacks. Expanding settlements and agriculture severed elk migration routes through the Greater Yellowstone Area, fragmenting elk habitat.

Chronic wasting disease of deer and elk: A review with recommendations for management. Every spring, tens of thousands of elk follow a wave of green growth up onto the high plateaus in and around Yellowstone and Grand Teton national parks, where they spend the summer calving and fattening on fresh grass. "These elk eat a lot of things, and they are eaten by a lot of things, so wherever these masses of hundreds or thousands of elk are on the landscape determines who gets to eat and who doesn't," Middleton said. — Drought and attacks by wolves and grizzly bears have diminished a more than 30-mile (50-kilometer) elk migration between Yellowstone National Park and foothills west of Cody, Wyoming. Yellowstone’s ungulates after wolves – expectations, realizations, and predictions. Borkowski, J.J., P.J. Elk are fed during the winter at the National Elk Refuge in Jackson, Wyoming, in addition to 22 Wyoming-run feed grounds. However, Rickbeil notes, the snow cover and vegetation couldn't fully explain why the elk are now arriving so much later at their winter ranges. White, R.A. Garrott, T. Davis, A.R. Houston, D.B. Yellowstone’s approximately 20,000 migratory elk are among the most important large mammals in the ecosystem, comprising about 10 million or so pounds of animal biomass pulsing in and out of the parks and adjacent wilderness areas each year — so where they can be found at any given time matters to both animals and humans alike. 2005. Another recent UC Berkeley-led study suggests that climate change is likely to hit National Parks harder than other areas of the country. The antlers of a typical, healthy bull are 55–60 inches long, just under six feet wide, and weigh about 30 pounds per pair. Yellowstone Center for Resources. The timing and routes of Northern Yellowstone elk migration closely follow the areas of seasonal vegetation growth and changes in snow depth. White. White, P.J., R.A. Garrott, K.L. Yellowstone's approximately 20,000 migratory elk are among the most important large mammals in the ecosystem, comprising about 10 million or so pounds of animal biomass pulsing in and out of the parks and adjacent wilderness areas each year—so where they can be found at any given time matters to both animals and humans alike.

Migration of northern Yellowstone elk - implications of spatial structuring. Hardy, A.R. Robbins, K.M. Yellowstone elk in their thousands leave the supervolcano each year to find higher grounds around the Yellowstone National Park. Research is under way to determine the relative effects of climate, hydrology, carnivore predation/avoidance, and herbivory on these woody species. "We found that the immediate environment is a very effective predictor of when migration occurs," said Gregory Rickbeil, who conducted the analysis as a postdoctoral researcher in Arthur Middleton's lab at UC Berkeley. "This [study] provides great insight into the adaptation strategies of elk to climate change in the Greater Yellowstone Ecosystem," said Jonathan Jarvis, former director of the National Park Service, who now serves as executive director of the Institute for Parks, People, and Biodiversity at UC Berkeley.
