"David J Bockman" expounded:

PS-- with regard to the Norway Maples, it is not a highly regarded landscape
tree-- it tends to have weak wood, shade out other desirable trees & shrubs,
and it's difficult to plant beneath (hogs for water).

Not only is it 'not highly regarded', it's a known invasive and really
should be removed. It produces thousands of very viable seeds, the
seedlings crowd out native maples everywhere they are allowed to grow.
