Why Does My Oak Tree Have So Many Acorns?

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 many acorns does an oak tree produce each year?

Why are there no acorns this year 2020?

The acorn shortage may be hard on squirrels, but it doesn’t indicate a problem for oak trees. It’s just part of their normal boom-and-bust cycle. Instead of producing a regular yearly supply of nuts, oak trees tend to have a bumper crop every two to five years. Botanists call that a mast year.

Is 2020 a mast year?

Every few years, some species of trees and shrubs produce a bumper crop of their fruits or nuts. The collective term for these fruits and nuts is ‘mast’, so we call this a mast year. With so many fallen acorns, observations suggest that 2020 is a mast year for oak.

Do oak trees produce more acorns some years?

Why do some oaks have no acorns?

There are hardly any acorns about now. It’s also because there was poor weather at the end of April which is crucial for the flowering of oak trees,” said Matthew Oates of the National Trust.
