An appeal by environmental groups to stop a timber sale south of Teasdale on the Boulder Mountain has been denied by the regional forester of the U. S. Forest Service.

The sale includes about one million board feet of timber on 1,730 acres in a roadless area on the north slope of Boulder Mountain in the Dixie National Forest. Officials said the sale will include ponderosa pine, adding that mostly old-growth timber will be cut.The acreage where the timber will be cut can be seen from U-24 south of Teasdale.

The sale is needed to stem the kind of insect infestation that has led to the Forest Service selling six million board feet of timber and proposing the sale of at least another 20 million board feed on Cedar Mountain, said Dixie Forest spokesman Mark Van Every.

An appeal opposing the sale was filed in September by the Southern Utah Wilderness Alliance and the Utah chapter of the Sierra Club. The sale was initially proposed last June by the Forest Service.

Environmental groups contended the timber cut violated federal mandates aimed at protecting environmental values and that the Forest Service inadequately addressed the economics of the local timber industry. The agency's assessment of wildlife populations and forest regeneration was questioned as well as whether the sale would harm wild turkey and mule deer habitation.

The appeal argued that the sale was not necessary because of the recent sales of millions of board feet of timber that was infested with insects.
