The oak trees in my yard are "masting" again. "Masting" is a strategy that oak trees have evolved where every few years, they produce so many acorns, that the squirrels and other animals that eat them, cannot keep up. It gives the oaks a better chance at reproducing. This year, acorns abound.

Do ash trees mast? Every 5-6 yrs my neighbor's ash drops *billions* of seeds. So many they form drifts in the street.

An oak limb just came down, as I was cleaning up I realized it broke because there were so many acorns on it, the weight took it off.
