Study finds Bush owl plan based on false conclusion that fire increasing threat to habitat

GRANTS PASS, Ore. (AP) — A new study challenges a basic justification
about the threat of wildfires that the Bush administration used to make
room for more logging in old growth forests that are home to the
northern spotted owl.
The study, appearing in the journal Conservation Biology, found no
increasing threat of severe wildfires destroying old growth forests in
the drier areas where the owl lives in Oregon, Washington and Northern
California.
"The argument used to justify a massive increase in
logging under the (spotted owl) recovery program was not based on sound
science," said Chad T. Hanson, a fire and forest ecologist at the
University of California, Davis, who was lead author of the study. "The
recovery plan took a leap-before-you-look approach and did it without
sound data."
The spotted owl was declared a threatened species
in 1990 primarily due to heavy logging in old growth forests. Its
numbers continue to decline, despite sharp reduction in logging on
federal lands in 1994 that caused economic pain still felt in the
region.
The Bush administration agreed to produce a new spotted owl recovery plan to settle a timber industry lawsuit.
The plan blamed declining owl numbers on the barred owl, an aggressive
East Coast cousin that has driven spotted owls from their territory,
and on wildfires that have destroyed old growth forests. It eliminated
habitat reserves in the Northwest Forest Plan and proposed aggressive
thinning in the dry forests of the Klamath Mountains and the east side
of the Cascades to reduce the threat of fire.
The Obama
administration told a federal court last April it would not defend the
Bush administration's plan because an inspector general's report
concluded it had been politically manipulated. The administration is
negotiating over the scope and timing for a review with conservation
groups that filed lawsuits.
"By July 30 we should know how we
are going to proceed," U.S. Fish and Wildlife Service spokeswoman Joan
Jewett said. "We will be reviewing the study, which is just the type of
information we'll be considering as we determine what, if any, changes
need to be made to the spotted owl recovery plan."
The study
took satellite imagery on fire severity from 1984-2005, and compared it
with government data identifying old growth forests on the east side of
the Cascades in Oregon, Washington and California, and the Klamath
Mountains of southern Oregon and California — all identified in the
recovery plan as having the highest fire danger.
The rate of
high-severity wildfires in old growth was 1.34 percent on the east side
of the Cascades, and 1.74 percent in the Klamath Mountains, the study
found. That amounts to a high-severity fire burning a given piece of
old growth forest every 746 years on the east side of the Cascades, and
every 575 years in the Klamaths.
The recovery plan looked at
smaller portions of the landscape than the study and shorter periods of
time, and extrapolated those results to reach its conclusions, Hanson
said.
"The existing recovery plan is so clearly based on these
incorrect assumptions that you can't just tweak it here and amend it
here and fix it," Hanson said.
Forests are actually maturing
into old growth suitable for owl habitat five to 14 times faster than
they are being burned by wildfire, added co-author Dominic DellaSala,
chief scientist for the National Center for Conservation Science &
Policy and a member of the spotted owl recovery team that fought with
the Bush administration over the owl recovery plan.
