Hi again Ethel

As you have requested i will quote from Brooker and Kleinig:

"As a generalisation, "forest trees" are single-stemmed and have a crown forming a minor proportion of the whole tree height, with the combined forest crowns occupying at least 30% of the ground cover. "Woodland trees" are single-stemmed although they may branch at a short distance above ground level, and have a crown occupying a major proportion of the tree height, with the combined crowns occupying less than 30% of the ground cover.

Having reflected on the above and the original edit I did I can see that there are interpretative errors in my edit. If you would like to make cleaner sense of the above in the article, as I see you have attempted in historic edits,then by all means, please,  go ahead.

Thanks
