Honestly they could be around here but I struggle telling the difference. I can pick out reds no problem at all. I printed out some cheat sheets to take to the farm Saturday since I don't have cell service there.
Found this map for 'em... http://r.search.yahoo.com/_ylt=A0LEVv3wfOBXIHQAXbcnnIlQ;_ylu=X3oDMTE0bzF1cTdnBGNvbG8DYmYxBHBvcwM3BHZ0aWQDRkZVSTNDMV8xBHNlYwNzcg--/RV=2/RE=1474358640/RO=10/RU=https://bouldertreecare.com/silver-maple-acer-saccharinum//RK=0/RS=zqoXnwMJtKk81GGmCVJN2bl_3ig- ...and a link to ID them...^ ^ ^
Things you can look for to tell the difference between red and sugar depending on the season: 1) Red leaves have a distinct angle in the sinus (The gap between the lobes of the leaf) whereas sugar will have a gentle rounded appearance. 2) red has red buds. 3) red gets helicopters first thing in the spring as it leafs out. Sugar seeds comes later in the season. Norway is pretty obvious by the bark. You shouldn't confuse that with anything.
Yes. But Norway will too. Other good identifier is that Norway is about the last tree to turn color and drop its leaves. If you have a maple that still is green or turning yellow long after everything has dropped its leaves you best be cutting it down.
They are invasive so you should cut them. They will croud out other native trees. They come with the small benefit that they make good firewood, although maybe not quite on par with sugar but a magnitude better than tree of heaven.
