ST. GEORGE — Much of the wood from the trees burned in this summer’s devastating Brian Head Fire is still useful, and the U.S. Forest Service is proposing a timber salvage along roads in the burn area. Officials from the Cedar City Ranger District say standing dead trees comprising mostly ponderosa pine and incidental amounts of spruce, fir and aspen have merchantable value if they are harvested before succumbing to insects and disease. The project proposal also cites public health and safety concerns, as some of the trees are along highly traveled routes and may produce road hazards. ……So far, comments have indicated support for the proposal, Jaros said, adding that some concerns were expressed regarding possible effects on the environment, including the impact on wildlife and hydrology.
