The Oregon Department of Forestry has issued a regulated closure for the lands it protects in its Central Oregon District as of Monday.  That means smoking is prohibited while traveling, except in vehicles on improved roads, and open fires are prohibited.  The use of portable appliances like camp stoves using liquefied or bottled fuels are allowed in clean areas free of flammable vegetation, and camp fires are allowed in designated areas.  Chainsaws, metal cutting, griding, and welding, and mowing dried grass with power equipment is prohibited between 1 p.m. and 8 p.m.  The use of motor vehicles is limited to improved roads except for vehicle use by landowners and their employees for activities associated with their livelihood, and the use of fireworks and blasting is prohibited.  In addition, ODF lands in Central Oregon have been placed under Industrial Fire Protection Level 2.
