"Portland, OR - 1988-90
Within days after our return from Chile, I learned that
I had been selected to fill the vacancy of Director of
Pest Management in R-6, a position that had been vacant
for nearly two years. A major outbreak of western spruce
budworm was underway in the Region, with several million
acres of forests suffering defoliation. Plans were
already underway for a large suppression project and I
arrived just in time for Regional Forester Jim Torrence
to announce that, based on the Environmental Analysis
that had been completed, he would authorize treatment of
up to 1 million areas providing they met the pre-spray
insect population densities that had been established.
That project took up virtually all of my time for my
first six months in R-6. We successfully treated 600,000
acres, all with undiluted formulations of Bacillus
thuringiensis. For the first time, we adapted the
Incident Command System (ICS), an organizational
structure for managing large wildfire suppression
projects, to insect suppression. We established five
Incident Command units and an Area Command in Portland.
The project involved deployment of over 70 helicopters, a
fleet of turbine powered fixed-wing aircraft and over 700
people. I believe it still stands as the largest single
western spruce budworm suppression project that involved
exclusive use of a biological insecticide. The project
was a great success and all of the units treated met the
post treatment criteria of
