As it was once explained to me, most trees have a thin layer of special
cells that form between the leaf and the branch.  When it is time for the
leaf to fall off, this layer dies and the leaf drops off easily.  Due to
a genetic defect, oaks lack this cell layer.  That is why it seems to take
forever for the leaves to fall, and why I seem to find myself raking the
leaves from my neighbors trees all winter long.
