I was about to post this very question, when this topic popped up on the side.
Sadly, the iNat help page does not provide a satisfying example for this case. I would say that the “humans intended it to be then and there” argument inclines me to consider remnant trees like this one or this one as NOT WILD. The tree is found at the place and time of the observation by a conscious human decision not to cut down this very specimen. Both trees from the examples I link are now in heavily modified areas and incorporated into cultivation, so that I’m weary of considering them wild no matter their origin.
