Silver maple (Acer saccharinum) is common through the South in river floodplains and is also planted a lot as a shade tree.. It is probably the lightest and weakest of the maples except for maybe box elder. It has really brittle wood, and I personally wouldn't try to use it for a bow if I could find anything else. With that said, though, Jamie (MichiganBowGuy) posted a bow awhile back that he said was made from silver maple, and it looked like a good'un.
