MINNEAPOLIS (WCCO) – The Department of Natural Resources is trying to find out why the moose population in the state is plummeting.

The DNR says the moose population has dropped by 35 percent over last year, and they called off this year’s hunt.

Now, some of the information is coming in to researchers. They say six of the 111 moose in the study have died.

At least two of them appear to be victims of wolf attacks. The high tech equipment lets researchers know when the moose have stopped moving for 6 hours.

Then, they can get to the dead moose quickly to find out what killed the animals.
