Six River National Forrest will close forest roads to motorists to prevent the spread of root disease. The closure goes into effect on a yearly basis at the start of the rainy season.
Six Rivers officials said the closures help stop a non-native pathogen that causes Port-Orford-cedar (POC) root disease. The spores, according to Six Rivers, live in water and wet soil and are easily transported by vehicles and mountain bikes, off highway vehicles and heavy equipment.
Areas within the Gasquet Ranger District/Smith River National Recreation area and in the Bluff Creek are infested.
The closures remain in effect until road surfaces dry up in the spring or early summer.
