[Tagging] tagging single trees

I can't see which information you are throwing away. You can do the
same analysis you did now and find, which tree has no other tree
within 50m (or any other distance you define). If there is another
tree, it is not a lone tree. Simple as that, you don't need a special
tag for it, but you need all trees mapped.

interesting. How did you check this? Are these trees inside forests?

cheers,
