There is a sizable literature devoted to trying to understand and predict
masting as a function of carb (and other e.g., fats) storage in trees and
plants in general. If there is interest in delving into this literature,
see citations below. According to this literature, there are many possible

Here in the DC area, where the acorn production of most oaks was practically
non-existent, the bur oaks also did fine (pretty good crop). As in Illinois,
the balck walnuts were in abudance, as were persimmons, and several other
trees. From what I've read about masting, it seems strange that a pa

Factors that result in high vs low production may depend on carb
stores and total annual carbon assimilation. But can't the timing of
extreme weather events, (rain, frost, etc) that damage flowers or
prevent adequate pollination, result in near zero mast crops? If so
will the carbs saved
The late freeze in April 2007 that spread across much of the central and
eastern United States had a big impact on oak mast here in Missouri (and
presumably lots of other areas too). The freeze hit when a lot of oaks were
flowering and killed the flowers and early leaves. Species with acorns t
Burr oak masted well in central Iowa, but red oak and most other nut trees did
poorly. I don't believe I have seen even one red oak acorn this year.

I have been collecting and watching in east Central Illinois for about 10
years now, and without a doubt it was a strange year here also. We had a
bumper crop of bur oak, and a good crop of hickories (shagbark and
shellbark) however, the red and black oaks were nowhere to be seen and the
white oak
I wonder whether the unexpected pattern seen in the oaks around DC this
year is due to factors which can complicate the masting pattern.
A few years ago I co-authored a paper using time series of masting in
relation to climate records (G. Piovesan & J.M. Adams in Ecological
Research).

We see a few, albeit very few, acorns in MD (not none). Friends at the
Smithsonian's Environmental Research Center (SERC) in Edgewater, MD told us
that there is a pattern of low, medium, high, low mast production that helps
foil squirrels and others that try to profiteer too much on the seed
