Hi David S. & All,
The following link is relevant...
https://www.nrcan.gc.ca/forests/fire-insects-disturbances/deforestation/172=
04?fbclid=3D
In brief, and drawing on memory, in a 25 year cross Canada survey, the=20
area temporarily deforested by fire, tree death and insect attack was 21=20
times the area deforested by cutting. Experience in the west likely=20
predominated in this survey and I suspect climate change was the=20
predominant force. They did not include wind damage likely because it is=20
difficult to survey.
So of the total area temporarily deforested, cutting was responsible=
=20
for 4.54 % and "natural causes" 95.45%.
My conclusion is; 21 is much larger than 1 and concern should be=20
addressed to the greater effect. Annuals quickly recover from a bad year=20
but trees must have acceptable weather throughout their life.
Our trees can tolerate freaky weather (I think except wind damage)=20
but not dry conditions which kill root ends and allow entry of fungi. =20
One proactive approach would be to improve soil conditions where=20
feasible and one of the more promising approaches involves carbon=20
storage. Charcoal does not decay and finely powdered charcoal increases=20
water and nutrient capacity of soil (see terra preta).
There are large areas of coarse sandy soil in Kings Co. and=20
Shelburne Co. Powdered charcoal thoroughly mixed with this soil to a=20
depth of 2-3 metres would be interesting on a trial basis. It would be a=20
simple to lay out a replicated trial.
