Dr. Karve,
The introduction of exotic pests and diseases through the transport of
plants or plant tissue has historically had devastating consequences. The
devastation may be rare, but it is still devastation. I don't consider it
to be unreasonable to practice caution when importing biomass, be it a
pile of wood chips from the local landfill, a Christmas tree from Idaho or
Pennsylvania, bundled pine from Oregon or bundled hardwood from China or
India. No doubt such caution may be manipulated by politicians and
protectionists, but that does not negate the need for caution.
My father was a microbiologist. One of his little sayings was "you can't
buy time." He said that in the context of human disease and the
politicization of public health. You can throw millions at an emerging
disease, but if you make no attempt to contain it through testing and
quarantines, you lose time, and laboratory research takes time.
Perhaps torrefaction, along with its other benefits, could be effective in
sanitizing biomass prior to shipping?
Respectfully,
Andrew Parker (Not AJH)
