Snowfall can restrict Columbian black-tailed deer use of winter habitat, in part by burying understory forage. Simulation models evaluating the tradeoffs between factors affecting energetics of mule deer or Columbian black-tailed deer during winter have identified the process of forage burial by snow as the dominant factor controlling deer energy status.
