Explain salvage logging
What will be an ideal response?
Salvage logging is the removal of dead trees, or snags, following a natural disturbance. From an economic standpoint, salvage logging may seem to make good sense. However, ecologically, snags have immense value; the insects that feed on them provide food for wildlife, and many birds, mammals, and reptiles depend on holes in snags for nesting and roosting sites. Opponents of salvage logging point out that conducting timber removal operations on recently burned land can cause severe erosion and soil damage. Salvage logging is part of the Healthy Forest Restoration Act enacted by the Bush administration in the wake of the 2003 California fires, although recent studies reported in 2007 indicate that salvage logging is not having the effects hoped for and may actually be increasing the severity of wildfires.
