Premise: There is presently something manipulating living trees and constructing crude wooden structures from dead trees and branches on the N. American continent, and these are broadly consistent and uniform manifestations to an extent not likely to be coincidental.
Questions:
1. Has any individual given an account of seeing this actually being done, as it was occurring?
2. Has any comprehensive study or survey been done to detect any patterns as to the location of these structures, relative to each another and other topographical features?
3. Has any silva culturist examined any of these features to offer an opinion on the likelihood of them occurring naturally?
I ask because I find it to be both the least compelling evidence of their existence, but highly intriguing at the same time. If this animal is leaving this number of tangible markers on the landscape, it not only offers an opportunity to track their locations fairly definitively, it also offers an area rife for conjecture on why they find this widespread activity so necessary. Aside from "It's a territorial thing", what else might there be to it?
