More than 90% of it looks like "uncultivated land covered with shrubs, bushes or stunted trees" in Bing and that also corresponds to what I remember when in the area. So wholesale deletion would be a bad idea.

More relevant is that in an area near your note are features that need mapping. I'd suggest therefore that this note be resolved and replaced by a new note requesting mapping here and anwhere else that appears not to be scrub.
