I made NONE of these cuts. They look like some beaver who has really sharp teeth. Only I dont live near any water. Not a beaver. Chances are, in order of likelihood based on sightings in my yard: rabbit, squirrel, ?????. My back yard is about 3/4 acre fenced by a 4foot wooden fence. I have never seen a deer in my back yard in almost 10 years of living here. I did see about a dozen bound thru the front yard once. I would bet money that it was a rabbit, except for the damage to the trident 3 feet off the ground. Must have one of those jumping piranha rabbits.
I found my Kitohime maple that was damaged, a ROR elm with the roots chewed. None of the azaleas or conifers were touched that I can see. A larger zelcova nor elm was touched. Looks like they concentrated in potted and in-the-ground maples. Little bastard is looking to become Hasenpfeffer.
