I may not have a better understanding but I lived about 20 miles
from Gary's qth with a full size quarter wave vertical for 160
that did the same thing. Adding more radials stopped it and the
antenna was stable summer and winter. I believe it has nothing
to do with the trees but ground soil conductivity or lack of
same.
