The last prescribed burns of the year are set for this week in the White Mountain National Forest.
The U.S. Forest Service has been setting fires since April all across the forest area in New Hampshire and Maine.
The controlled burns are a way of restoring habitat and reducing the risk of wildfires.
Weather permitting, North Country residents might see smoke or roads closed in parts of the forest on Wednesday and Thursday.
Burn season must end after May 31, when nesting season for the protected northern long-eared bat begins.
