I've noticed different tree species throw their parties at different times. Assuming that its not just a bad year for plants like last year was, where everything is impacted. If the White Oaks are having a bad year, its likely that the Red Oaks or the Hickory trees will be bearing heavier than usual. I've walked in the woods for years; this is the impression i have from that experience. I don't see a good way to capture this in numerical data form, tho. You'd have to have a pretty good and consistent sampling technique over maybe 100 acres of forest; and would probably need to do sampling on multiple patches that size at some distance from each other. Over a span of decades.
