[Naturens] O. fagi

Dear All,     Some days ago I asked where O. fagi was present in NS. And today noticed a reply to the effect that such information would be found at iNaturalist. The information there was in effect; everywhere which is no more of use than a map which consists entirely of white paper. START OF DIGRESSION    Very briefly; agriculture, settlements and urban areas are generally on the better soils except for ports where location by a suitable harbor is key. And woodland tends to be on the poor leftovers.     But even in farmed soils, unfavorable profile features can make for a 10 fold difference in rate of apple tree growth and yield on rows 100' long.  Or for heaving and longevity of trees. END OF DIGRESSION     The specific locations of even 100 sites where O. fagi has overwhelmed Beech trees and 100 or less where it has not might offer a clue for best management of this pest; GPS readings converted to Long. & Lat.   In 1972 a good soil survey map was prepared for the entire province of NS. Surveys of entire provinces are expensive so I expect copies are still in stock. If not I have a copy.     For orientation purposes (is there any association between damage by O. fagi and soil type ?) one would need only (1) a qualitative evaluation of beetle damage by late August and (2) some evaluation of tree vigor e.g. typical shoot extension by late August. And a brief site description; approximate slope, exposure and vegetation. e.g.  grassed lawn,  grassed field or woodland.     These are just suggestions based my a first hand unfamiliarity with the facts. Those who have seen O. fagi damage will be in a better position to improve on the above. Dave, Kentville
