That report was rec= eived and has not been released to the public. Early in 2015, the Federatio= n of Nova Scotia Naturalists was going to use a freedom of information requ= est to get access to that report. During that process it was found that a r= eported had already gone through the process, but that the report had been = so heavily redacted as to be useless. So here we have a report on public land, paid for a produced by the public = and yet we cannot see what is in it. That alone tells me that things can't = be good, otherwise the government, you would think, would be more than happ= y to show documentation that their existing policies are fine=85 Pat On Jan 11, 2016, at 7:21 PM, David & Alison Webster wrote: Hi Nick, David P. & All Jan 11, 2016 I would be cautious about betting the farm on Ca depletion being a major = factor. One telling passage in the Noseworthy thesis is "To what extent the appare= nt luxurious consumption of Ca is beneficial to tree growth remains to be e= xplored..." (p. 194). This is a very complex model as it stands but, so far as I can tell, make= s no allowance for consumption of H+ by weathering of soil minerals so the = effect of acidic ppt. may be overstated to some degree. And, so far as I ca= n see, it is a balance sheet and consequently does not allow for possible r= esponses of soils or trees when inputs or outputs change. Phosphorus was excluded unfortunately. But as the model stands it is I th= ink an excellent launching pad from which to define questions that need tes= ting by experiment. A narrow band of basic soils appears on both sides of most waterways, in = the area most intensively studied (Kejimkujik National Park) suggesting tha= t the acidity of soil water, as it passes through acidic soil upslope, is s= lightly neutralized (weathering effect ?). Whether these bands were a predi= ction of the model or an observation of soil survey I am unsure. One feature of large expensive equipment is that it will tend to be used = regardless of soil conditions. A few passes over soil when it is sufficient= ly wet to be compacted may result in damage which will take decades to reve= rse. If harvesting by large equipment does in fact reduce growth of the nex= t generation of trees then it could be due to changes in soil porosity at 4= 0 cm or beyond and not nutrient removal. I must become less involved with this question because in less than a mon= th I have blown a year's allotment of discretionary time and trying to herd= cats up a waterfall is not an efficient use of scarce time.
