I am gathering data about naturalisations of Callery Pears. I noted your comments at 4651191. I am supposing that this is in the same grassy woodland at Mount Majura.
I am not familiar with Naturemapr as a way to communicate. I am hoping that I can look for an answer at this same page.
For this one I will ask the same question: Do you think this was planted deliberately, or sown by seed dispersal or grown from a sucker? Thanks, Kate
