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
