WILLIAMS, Ariz. (AP) - New restrictions aimed at preventing human-caused wildfires are about to take effect in two northern Arizona national forests.

The restrictions set to be implemented Thursday for the entire Coconino and Kaibab forests prohibit fires, campfires and use of charcoal, coal and wood stoves except within a developed recreation site.

Smoking is also prohibited, except within an enclosed vehicle, building or a developed recreation site.
