POLK COUNTY -- The Oregon Department of Forestry's West Oregon District announced that fire season began on Tuesday in Polk, Benton, Lincoln and southern Yamhill counties.The West Oregon District protects approximately 1.1 million acres of private and public lands from wildfire. The fire season designation means certain restrictions on work activities in the forest. Industrial Fire Precaution Levels (IFPL) are part of ODF's closure system that regulates industrial activity in the forests of the Coast Range. With fire season in effect, the districts are currently at IFPL 1, which imposes the fewest restrictions.Industrial operations are required to have firefighting equipment on site and complete a fire watch after work activities have ceased for the day. Since restrictions may vary, it is advisable to check with the nearest ODF office for rules specific to the local area.IFPL details can be found at: http://www.oregon.gov/odf/pages/fire/ifpl.aspx."With the current and predicted weather, summer is finally here," said West Oregon Assistant District Forester Ted Erdmann. "We want to get out in front of the situation, since fire danger is increasing."Entry into fire season chiefly addresses industrial forest operators, but if the warm, dry weather continues, additional restrictions may be added on recreation and other activities.For more information on the restrictions imposed by the fire season declaration, contact the nearest Oregon Department of Forestry office.
