Ha, ha, I didn't mean to be confusing on that other thread about being an arborist. I think of an arborist as a member of that paying profession that cares for trees. Maybe that fits me too! Thanks John_KAYS for your support. Not relevant to anything at all, perhaps, but Alex Shigo never called himself an arborist or arboriculturist. When I met him, his business cards for the Forest Service said "Chief Mycologist". Most of his research peers during his FS career considered him a forest pathologist.
I shouldn't get hung up on labels. I might be just a tad defensive in that I've been told that arboriculture is just a sideline for me because I don't actually prune/fertilize/climb/ etc., or make a monthly payroll for those that do. I've been told that I don't understand what it takes to support oneself doing those things. That all could well be true. I'm certainly not "certified". And my job evaluations are based on publications, primarily in research journals and (very) secondarily on trade or practitioner publications like TCI, Arborist News, Consulting Arborist, etc.
I probably shouldn't be defensive that way. I've also said publicly that I'm not a real dendrochronologist even though I've been on the executive board of the Tree Ring Society, (the primary research society for dendrochronology) for more than a few years. My dendrochemistry work has been featured by the American Chemical Society, but I don't have the nerve to call myself a "chemist". So this is a character defect of mine, to shove off criticism in advance. I should stop doing that. I'll try to do better.
In my internal fantasy world I probably call myself a "Tree Biologist". That has applications for arboriculture, pathologist, forestry, dendrochonology, etc. My official government title is "plant physiologist". Most of my fellow researchers consider me a forest pathologist or mycologist.
