Six Rivers National Forest Beginning Seasonal Closures for Port-Orford-cedar Protection
This is a press release from the Six Rivers National Forest:
EUREKA, Calif. – With the anticipation of fall rains, Six Rivers National Forest Supervisor Ted McArthur has announced that some roads and campgrounds in the central and northern parts of the forest will be closed to motor-vehicle use within the week 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 vehicle tires and hiking boots, as well as horse hooves and dog paws.
“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, POC 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 infested POC areas on the Lower Trinity Ranger District. Port-Orford-cedar does not grow on the Mad River Ranger District.
The following roads and campgrounds have been/or will be closed within the week:
