Primed
for Disaster
How
can we prepare for the coming fires? BY

A grass fire that jumped into the woods and threatened
homes near Fern Ridge was recently headlined in The Register-Guard.
Apart from media sensationalism, there was an element of reality
behind the front page flames. Cooler weather has dampened our fire
consciousness, but people affected by this fire are taking measures
to reduce risk in the inevitably hotter, dryer, breezier days to
come.

Largely the result of systematic fire suppression
and overplanting, our crowded urban forests are primed for dysfunction
and ignition. From the top of Spencer's Butte, stressed old trees
are visible throughout the conflagration-ripe forestscape. Shade-intolerant
native oaks and pines that thrived in open pre-Euro conditions created
by frequent low-intensity fires are dying out due to pressure from
unchecked younger trees and undergrowth. With or without human intervention,
this overly dense forest will likely reset itself. If by wildfire,
homes and heritage trees will be at great risk.
The Berkeley Hills (Calif.) community, warned often
by foresters and firefighters about the crowded condition of their
forest, took the gamble of "Let's leave it alone." In 1991 a wind-driven
fire did a billion and a half dollars of damage, ravishing 1,600
acres and 3,800 homes and killing 25 people. Months before, at a
Bay Area forestry meeting, I toured these hills with Gordon Robinson,
then Sierra Club's venerable forester. Pointing out deadend streets
overloaded with brush and trees, he muttered "No chance for people
or forest." Unfortunately, his unheeded prophecy was fulfilled.
For 20 years I've designed and participated in private
and public thinning and fuel reduction projects at varying scales
and forest types, including Eugene's south hills. The timber industry
damned me for not being one of theirs and promoting something less
than clearcutting As Native Forest Councils forester, I was criticized
by many environmentalists for violating Zero Cut's tenant. Still,
sites I worked on and revisited are healthier — less stressed,
more diverse and distinctly more fire resistant. When the forest
breathes easier, that's thanks enough.
Prudently honest thinning and fuel reduction projects
are still being criticized by environmentalists. A park land project
on Spencer Butte's south slope designed to release scarce oak and
pine habitat from suppression-induced encroachment was stymied by
the South Hills Association. Ironically, their spokesperson lives
in an overgrown site adjacent to the project area at the end of
a narrow, fuel loaded deadend road. As in the Berkeley Hills, he
and his neighbors could easily be fire trapped. Meanwhile, they
get to watch the old oaks die.
During a 2002 wildfire, the Forest Service lit back
fires that burned across a Siskiyou National Forest inholding I've
been connected with for 30 years. We had thinned to maintain diversity
and big trees, kept grasses and berries cut low, fuels burned and
scattered, perimeter trails scarified, and put in a pump truck-accessible
pond. Our work and, yes, our prayers, saved cabins and most of the
20 acres from the Biscuit Fire.
What Biscuit clearly illustrated on less fortunate
sites, however, is that when a big blaze rises up to a hot wind,
organic material gets blown away with little regard to distance
or density. Thinning, pruning, pre-burning, scarifying and water
storage will not guarantee that forests or homes will withstand
a firestorm. But timely preparations can dramatically increase the
odds for ecological and economic survival. Had my cabin and surroundings
been consumed, I might still have rejoiced at the harsh but gracious
rebirth the fire gave the forest. But my personal philosophy and
a $40,000 structure doesn't match a south hill family's half million
dollar home with their lives sheltered and archived inside.
So here's advice to urban forest dwellers from an
old woodsman who's seen and worked in many forests and fires: Care
for yourselves and your forests by being prepared. Losing forest
diversity, history, resilience and human security to a century of
fire suppression, we're taking huge risks by not taking action.
