What type of borer is attacking this ash tree? (Image Album)
ItÃ¢ÂÂs in really bad shape, and has been for a while. I took down a couple large branches (4-5Ã¢ÂÂ) that were completely dead two years ago.
The last four pictures are of the base of one of those branches that I finally sawed off this year. ThereÃ¢ÂÂs no apparent damage to the core of the branches, and none of the bore holes seem to go much deeper than just beneath the bark.
About half the branches on the tree altogether are now bare. The other ash trees around it have some dead branches as well, and the bark looks like it is coming off on some of the higher branches.
This is in Sioux Falls, SD, which should be out of the range of EAB and some of the other common borers.
