FILE - In this April 18, 2012, file photo Mark Baker feeds bread to exotic swine on his farm near McBain, Mich. Baker of Missaukee County defied an order designating Russian boars and similar breeds as invasive species that are off-limits in Michigan. The Department of Natural Resources said the ban was necessary because the hogs were escaping from farms and game ranches, breeding prolifically and damaging the environment. Baker insisted his animals weren't causing problems. The DNR threatened to fine him $700,000. But last week, the department said he no longer had the offending breeds. Instead, all his pigs were hybrids that complied with the law. (AP Photo/John Flesher, File)
