Thanks Ken and others for your thoughts and ideas. The property on question has been sold to another buyer so our search continues, but I’m glad to be learning from what we found with maples in this property. It’s funn you mention the general forest health including critters, because I comparison you a couple dozen other properties we’ve walked, this had less deer and moose scat that’s we’ve seen. We wondered about that, but have found no explanation. A forester local to the area however said his guess would be pear thrips, an sap sucking insect I hadn’t heard before. There were no leaves low enough on these trees to grab and look at up close, so my observations were all at a distance of at least 30’.
