Burned trees are an
essential part of a healthy forest
Post-fire salvage logging may harm our forests
Wildfire is an essential natural process, which has shaped
the forests of western and northern North America for millennia,
providing renewal and rejuvenation. However, immediately following
a fire, forests are incredibly sensitive and need time to
heal naturally. Burned trees play a vital role in forest rejuvenation
after a fire, and scientific research has demonstrated that
logging of burned trees - often referred to as 'salvage' logging
- may hinder these natural processes.
Forests are not destroyed or lifeless following fire. Burned
trees play an essential role in a healthy forest ecosystem.
- Standing dead trees and fallen logs-which salvage logging
removes-provide critical habitat for species including
lynx, marten and fisher.
- Cavity nesting birds that thrive in post fire forests
include pileated and black backed woodpeckers, northern
goshawks and boreal owls.
- Standing dead trees provide shade, stabilize and regulate
the water flow on post fire soils.
- The eventual decay of fire burned trees recycles important
nutrients that increase forest productivity.
Most scientists agree that post-fire logging is not beneficial
and agree that post-fire logging can severely damage soils,
streams, vegetation, and wildlife and has no ecological benefit.
- A recent report authored by eight scientists (Beschta
et al. 1995) states that while "there is little reason
to believe that post-fire salvage logging has any positive
ecological benefits
there is considerable evidence
that persistent, significant adverse environmental impacts
are likely to result from salvage logging."
- The U.S. Forest Service (USDA 2000) recently reviewed
the results of 21 studies of post fire logging and concluded
"we know enough about both logging activity and structural
change to recommend caution" in post fire logging.
Post-fire logging does NOT reduce the intensity of future
wildfires. The Forest Service claims that post-fire logging
projects can reduce the intensity of future fires by removing
fuels; however, science does not support this claim.
- The USDA Forest Service report states "we found
no studies documenting a reduction in fire intensity in
a stand that had previously burned and then been logged."
- The Beschta report states that they "are aware
of no evidence supporting the contention that leaving
large dead wood material significantly increases the probability
of reburn."
Post-fire logging has few, if any, economic benefits. Economic
revenue does not justify post-fire logging.
- Burned wood sells at low prices.
- The need to protect the fragile post-fire forest from
the impacts of logging results in high costs.
- Post-fire logging may destroy economically valuable
ecosystem services such as air and water purification
and wildlife habitat.
- Prioritizing scientifically based restoration activities
and home protection will produce numerous job opportunities.
Let's concentrate on protecting homes and lives. The Beschta
report suggests that forest managers should prevent logging
from interrupting post fire forest rejuvenation. The main
finding of the Beschta report is that "most native species
are adapted to natural patterns and processes of disturbance
and recovery in the landscape and that preventing additional
human disturbance (and reducing the effects of past disturbance)
generally will provide the best pathway to regional ecological
recovery."
Instead of removing burned trees that are an important part
of the natural cycle of forests and fire, post fire projects
should focus on repairing the ecological damage associated
with logging, roadbuilding and grazing on our National Forests
and protecting homes in and around forests.
