Feral swine can cause damage! They can eat everything in sight, affecting wildlife forage and ag lands. They reproduce quickly and a herd can cover an area up to 10,000 acres. Feral pigs carry 35 known diseases, 13 of which are transmittable to humans. A Texas woman was recently attacked and killed by pigs.
An ODFW spokesman said he believed there were herds in the Ochoco National Forest and in the Prineville and Ashwood, Oregon areas. In 2006, a herd of feral pigs were sighted in Harney County, but so far have not been reported as a problem. Landowners and managers are required by law to notify the Oregon Department of Fish and Wildlife if they know feral pigs are on their property. A removal plan can be set up. The Oregon Hunter’s Association has provided grant money for trail cameras and trapping programs. The ODFW is allowing aerial shooting and sport hunting as well. Feral pigs are considered non game and are non protected, and so can be hunted year round, but you should notify ODFW prior, have a valid hunting license, and get landowner permission (if it is on private property).
