Salvage logging

Salvage logging is the practice of logging trees in forest areas that have been damaged by wildfire, flood, severe wind, disease, insect infestation, or other natural disturbance in order to recover economic value that would otherwise be lost.

Although the primary motivation of salvage logging is economic, it has also been suggested that salvage logging may reduce erosion, reduce intensity of future wildfires, and slow buildup of pest insects. However, there is little evidence to support such claims, and most evidence supports the view that salvage logging is harmful to forest health and function.

As with other logging operations, the harvesting may be either by selection, thinning or clearcutting, and a regeneration plan may be put in place after the logging. Salvage logging may include removal of remaining live trees in predominantly dead stands.

One highly publicized instance of salvage logging followed the Biscuit Fire in Oregon and California in 2002. Since the fire, the United States Forest Service has been salvaging burned timber in the area. The process was expedited when President George W. Bush signed the Healthy Forests Restoration Act allowing salvage logging to occur more quickly and with reduced threat of lawsuits.President Bill Clinton signed an earlier piece of legislation promoting salvage logging (commonly referred to as the Salvage Rider) as part of the Omnibus Rescissions Bill on July 27, 1995.

Forests across western North America impacted by recent mountain pine beetle infestations are currently being salvage logged. Salvage logging after windthrow is also common.

Salvage logging is of particular concern ecologically because disturbed landscapes tend to be under appreciated and undervalued, and therefore more imperiled than other successional stages on the landscape. Concerns include forest structure and wildlife habitat, future fire impact, nutrient cycling, and erosion.
