Also, dead trees do more than just take up space. Decaying wood is a highly suitable habitat for insects such as the spruce bark beetle, which in large numbers can damage live, healthy spruce trees. So, by removing totting wood, salvage logging helps minimize the dangers of insect infestation, thus contributing to the health of the forest.
同时,已死的树对森林的损害不仅仅是占用空间。腐烂的木头同时也是昆虫很好的栖息地,比如杉皮甲虫。大量的杉皮甲虫会对健康生长的杉树造成损害。所以,通过移走这些腐烂的木头,回收性砍伐可以降低虫害侵袭的危险,进而保护森林的健康。
Third and last, salvage logging has economic benefits. Many industries depend upon the forests for their production, and because of this a fire can have a very harmful effect on the economy. Often, however, the trees that have been damaged by natural disasters still can provide much wood that is usable by industries. Furthermore, salvage logging requires more workers than traditional logging operations do, and so it helps create additional jobs for local residents.
最后,回收性砍伐是有经济收益的。很多的产业的产品生产都依赖森林,因而森林大火对于经济的发展是非常有害的。但是,很多时候这些因为自然灾害死亡的树木还是可以能够为工业生产提供很多木材的。而且,回收性砍伐比传统的砍伐活动需要更多的人力,所以这可以为当地居民提供更多的就业机会。
