Q: I have short 6 to 8 inch pieces of my pine tree falling off. The ends look like they have been chewed through. I have over 24 of these section laying under the tree. The tree is large with a base of over 24 inches. What is happening ?
Several folks said they had seen the same thing. Marcus M., though, made an interesting observation that this fall sighting coincides with squirrels frantically eating pine seeds from cones in preparation for winter. See his photos below.
My neighbor has the clusters you have PLUS lots of gnawed pine cones on his driveway.
I think squirrels are tearing off pine cones to get at the seeds and in the process are breaking clusters of needles which then fall to the ground.
