Roads, Campgrounds Reopened in Six Rivers National Forest Where Port-Orford-Cedar Are Prevalent

This is a press release from the U.S. Forest Service:

EUREKA, Calif. – Acting Six Rivers National Forest Supervisor Liz Berger announced…that roads and campgrounds in the central and northern parts of the forest, where Port-Orford-cedar (POC) are prevalent, have been opened.

Every fall, the forest closes campgrounds, roads and trails with the onset of the rainy season to reduce the risk of spreading Phytophthora lateralis (PL), the non-native pathogen that causes POC root disease. Under wet conditions, pathogen-laden soil can be spread from infected to non-infected areas. The pathogen—or spores—live in water and wet soil, and are easily transported by vehicles, including mountain bikes, off-highway vehicles, and heavy equipment, as well as by people and animals.

“With the rainy season behind us and soils drying out, we can now open our remaining campgrounds and roads that we had closed to protect Port-Orford-cedar,” said Berger. Port-Orford-cedar trees infected with the disease will die—young trees die within a few months of infection and mature trees within two to four years.

A complete list of roads closed in the fall is available at For additional information about POC, visit or contact Jeff Jones at (707) 441-3553.
