LAKE CITY, Mich. (AP) - A northern Michigan judge has dismissed dueling lawsuits between the state Department of Natural Resources and a farmer who was raising exotic hog breeds.

Missaukee County Circuit Judge William Fagerman on Wednesday dropped the suits by the state and Mark Baker.

Baker was challenging a 2011 state order declaring Russian boars and similar breeds as invasive species. State officials say the exotic swine are escaping into the wild and damaging the environment and farm crops.

Baker says his hogs don't do that.

Department spokesman Ed Golder tells The Associated Press that Baker no longer has the species on his land and says there's no reason for the legal cases to proceed.

Baker's farm is near McBain in the northern Lower Peninsula, about 45 miles south-southeast of Traverse City.
