An unusual pattern of springtime elk deaths for more than a decade in northern Nevada has scientists searching for answers. Researchers are focused on a herd of elk north of Elko, in the Independence and Tuscarora mountains, that have been mysteriously dying. In some years, 10% to 30% of collared females in the affected population have died.
The phenomenon has an informal name: seasonal elk mortality syndrome. University of Nevada, Reno researchers are working with the Nevada Department of Wildlife in an attempt to understand what’s causing it. One clue is low copper levels in corpses.
But scientists are still working to understand how mineral imbalances affect wild elk, and whether they contribute to disease or mortality. Ava Window, a UNR researcher, said the Nevada study could help scientists better understand how nutrition affects elk health across the West.
