LOGAN -- An ongoing wildlife study is tracking the mortality rates of Utah's mule deer population.
The Herald Journal of Logan reports preliminary data from the three-year program has found about 85 percent of adult female deer survive from year to year. Only 50 percent of fawns survive.
Utah's Division of Wildlife Resources spokesman Mark Hadley said the study began in 2009. Biologists tagged more than 400 deer that year with electronic collars in seven areas across the state.
If the collar stops moving for an extended period of time, it sends a mortality signal to biologists.
