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.
