ST. PAUL — Minnesota bear researcher Lynn Rogers has taken his battle with the Department of Natural Resources to court.

Rogers sued the DNR Tuesday. His lawsuit asks the court to allow Rogers to continue his work putting radio collars on wild bears.

Monday, Rogers asked Gov. Mark Dayton to overturn the DNR’s decision to not renew the permit for Rogers’ Ely-based Wildlife Research Institute. Dayton declined to do so, but said Rogers could seek a review by an administrative law judge.

The DNR contends Rogers’ practice of hand-feeding bears has made them too accustomed to humans, creating a public safety threat. Rogers disputes that his methods make bears unafraid of humans

The DNR plans to file its response by the end of the week.
