This THP is about 10 miles east of Rio Dell, CA, near Highway 36 and Grizzly Creek Redwoods State Park. Humboldt Redwood Company wants to tractor, cable and helicopter log at an elevation of 450 - 1600 feet in the Grizzly Creek watershed. Grizzly Creek flows into the Van Duzen River, which is impaired for sediment and temperature due to intensive logging in the area. Helicopter logging is planned likely to remove some large trees from 5 stands that contain marbled murrelet habitat. HRC also plans to use tractors on steep slopes in units designated for cable logging. There are several areas with landslide terrain and debris slides; mostly along stream channels.
