Some Roads, Campgrounds in Six Rivers National Forest Closed Until Late Spring/Early Summer to Reduce Risk of Port-Orford-cedar Root Disease
This is a press release from the U.S. Forest Service:
EUREKA, Calif., November 21, 2017 – Six Rivers National Forest Supervisor Merv George Jr. announced today that with the onset of the rainy season, some roads and campgrounds in the central and northern parts of the forest have been closed to motor-vehicle use to reduce the risk of spreading Phytophthora lateralis (PL), the non-native pathogen that causes Port-Orford-cedar (POC) root disease.
These seasonal road and campground closures are in effect until road surfaces dry out in late spring or early summer, minimizing the potential spread of the disease. Under wet conditions, pathogen-laden soil is easily spread from infested to non-infested areas by vehicles, including mountain bikes, off-highway vehicles, and heavy equipment, as well as by hikers, hunters, horses and dogs.
“Even if you’re just hiking in these wet areas, cleaning off your muddy boots before walking behind a closed gate can prevent the spread of the disease from one watershed to another,” said Jeff Jones, the forest’s vegetation program manager. He added, “It’s important to observe these POC road closures, because the pathogen generally doesn’t spread into areas where there is no access.”
Once the root disease is introduced into an area, Port-Orford-cedar trees will die—young trees within a few months of infection and mature trees within two to four years.
There are many infested POC areas on the Gasquet Ranger District/Smith River National Recreation Area (NRA) and in the Bluff Creek drainage on the Orleans Ranger District. There are a few POC areas on the Lower Trinity Ranger District, and none on the Mad River Ranger District.
The following roads and campgrounds have been closed with the onset of fall rains, and will re-open in late spring/early summer once the roads have dried out:
