美国林务局研究发现,挽救利用受中欧山松大小蠢侵害的木材在西部的一些地区效益显著。美国林务局的研究人员最近发表的一项研究评估了采伐美国西部受中欧山松大小蠢侵害的立木的潜在收益。该研究表明这项行动在美国西海岸和落基山北部各州可以活跃木材市场并取得显著收益,但是在位于落基山中部的科罗拉多州、犹他州和怀俄明州,挽救虫害木材的行动不会取得经济收益。美国西部地区的中欧山松大小蠢侵害造成山坡上遍地可见死亡的松树,特别是黑松。受害的大部分是国有林地的林木。决策者和森林 US Forest Service research found that salvage the use of the size of the Central Plains pine stupid wood in some parts of the western region significant benefits. A recent study published by researchers at the U.S. Forest Service assesses the potential benefits of harvesting standing stumps of Central American pine that are stupid in the western United States. The study shows that the operation can generate significant gains in the timber market on the west coast of the United States and in the northern Rocky Mountains, but no economic gains will be realized in Colorado, Utah and Wyoming in central Rocky Mountain. The size of the Central American pine tree in the western United States is stupidly infested with pine trees, especially pine, that can cause death on the slopes. Most of the victims are trees in state-owned woodlands. Policy makers and forests
