On the average, most species produce a good crop of acorns one year in three or four (Beck 1977, Christisen and Kearby 1984, Downs and McQuilkin 1944, Goodrum et al. 1971). In years of low or moderate acorn production, most acorns are consumed by insects. Moreover, the production of acorns differs among species.
How often do oak trees produce acorns?
Do oak trees produce acorns every year?

Why are there so many acorns in 2021?
Winter 2021:Almanac says we're in for one of the coldest winters in 'years. … A mild winter can often mean more acorns since white and red oak trees are able to produce more of them when they start creating seeds in the spring.
Why do oak trees have more acorns some years?
Boom and bust cycles of acorn production do have an evolutionary benefit for oak trees through “predator satiation.” The idea goes like this: in a mast year, predators (chipmunks, squirrels, turkeys, blue jays, deer, bear, etc.) can't eat all the acorns, so they leave some nuts to grow into future oak trees.
How often is a mast year for acorns?
every two to five years Oaks and several other tree species occasionally produce enormous crops of seed. This is called “masting” or “mast events”. These events are periodic. In the case of many oak species, a large mast event may happen every two to five years, depending on the species of oak and several other factors.
Can I stop my oak tree from producing acorns?

Why is there so many acorns in 2020?
Autumn is the time for falling leaves, conkers, and acorns. But this year, there are fewer acorns than normal. This is partly because oak trees operate in a 'boom and bust cycle' – in 2020 oak trees made so many acorns that this year they don't have as much energy left, so won't be able to produce as many.
