There is no such thing as “chemically sterilized trees”.  Private tree farms may use herbicides before planting seedlings so the trees have a chance to grow before the weeds choke them out, and on grand occasion they will use fertilizer. Herbicide and fertilizer is not used on public lands.  No one is logging old growth.  The mills can’t even handle big logs like that anymore.  Roy is still living in the ‘80’s and trying to perpetuate an extremism based on fear.  Truth: there are more trees in Oregon today than there were 100 years ago.  Truth: it is in both the public’s and industry’s best interest to keep it that way.
