BY STEVE BOWERS
I've heard many speakers on a
variety of forestry topics over the
years. Most of them are long
forgotten. A few made more of an
impression and are remembered more
clearly. One such speaker, is Dr. Alex
Shigo.
Dr. Shigo, until his retirement in
1985, was chief scientist with the US
Forest Service. His research on tree
decay and discolouration was quite
revolutionary and significantly
changed human understanding of
how trees react to wounding and
resist the spread of decay. His work
investigating tree decay started in the
late 1950s and was made possible by
the development of a new research
tool: the modern, one-man chainsaw.
This new tool allowed him to dissect
trees longitudinally and get an
internal perspective of processes
taking place in response to wounding.
Dr. Shigo states that trees are
generating systems, unlike humans
which are regenerating systems. One
of the most common mistakes made
in understanding trees is assuming
they respond to wounding in a similar
manner that people do.
Unlike people, trees do not heal.
Humans and other animals have the
ability to respond to wounding by
healing or regenerating tissue, i.e.
replace and repair cells in the same
location as the ones that were injured.
Trees on the other hand can only
