FAQ

I have a large maple tree dropping clumps of leaves with seeds (helicopters). These clumps seem to be from the ends of branches. I don't recall the tree doing this before. I don't know if it is just squirrels, or if someting else can cause this. The edges of the stems seem to be rather clean, more like a cut than a chew or a break. I also have noticed this happening to my neighbors maple. My oak tree next to the maple is not affected. Can you please advise? Thank you.

What you are describing is most likely squirrels. Their teeth make very clean angular cuts and spring is the time of year they make new nests for their young. The new growth on maples is very delicate and easy to chew through and the leaves make for very comfortable bedding.
