From Minnesota Public Radio:
Wildlife managers say Minnesota’s gray wolf population remains stable and healthy.

The Minnesota Department of Natural Resources released its annual estimate Monday. The midwinter survey put the state’s population at 2,655 wolves and 465 packs. Given the survey’s margin of error, the DNR says that’s statistically unchanged from last winter’s estimate of 2,856 wolves and 500 packs.
