Ash trees alas. These two ash trees make up most of the tree canopy over my back yard, and as you can see they are not doing well. The dead branches and sparse canopy are both symptoms of emerald ash borers, not to mention the woodpeckers regularly visiting the trunk. I had an arborist confirm that they need to come out, which will completely change the light in the yard, but also give me the chance to introduce different plants.
