Hello everyone new to the forum and new to trees. I have a very large what I believe is a green maple tree on my property that has a few holes in it. One hole looks fresh and appears to have shavings or something being expelled from it recently. Here are some photos. The second photo is a bit hard to make out but thats the fresh hole that is creating the sawdust. There is also some bark missing on the trunk. I would not be opposed to hiring an arborist but most people who would come are tree cutting companies who are looking to just cut it down.
