The ecological web contributing to a sarcoptic mange epizootic in coyotes of the Mojave Desert, Fort Irwin, California

February 2015 - March 2018


Participating Agencies

  • Department of Defense, Fort Irwin

In order to minimize the human-wildlife conflict on Fort Irwin, we intend to explore the ecological web surrounding the sarcoptic mange epizootic in the resident coyote population and thereby develop mitigation strategies to lower disease prevalence and the overall abundance of coyotes. Our objectives will be to estimate the size of the coyote population inhabiting the base, describe the patterns of spatial use by the resident coyotes, explore the potential factors contributing to the maintenance of sarcoptic mange, and examine for other parasites and diseases through fecal, epidermal and blood assays. Through this process, we hope to identify and suggest mitigation strategies that can be adopted by the base administration that will reduce the size of the resident coyote population and enhance its health thereby reducing human wildlife-conflict and the potential for spread of disease to humans and pets.
