How often do beech trees mast?
Beech is considered a species with a basic 2 years mast cycle (Matthews, 1955; Braun et al., 2020a; Nussbaumer et al., 2020).
What are beech masts?
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. Two of our most recognisable trees, oak and beech, fluctuate massively year on year in the amount of acorns and beech nuts they produce.
Why do mast years happen?
A ‘mast year’ is when trees go on a reproductive binge and produce a bumper crop that inundates the forest floor with nuts and seeds. Nut and seed-bearing trees like oaks, white spruce, sugar maples, beech and hickory trees all have mast years.
Is 2021 a mast year?
You may notice this year there are far more acorns falling off oak trees than we usually find. This is because 2021 is a “mast year,” when the trees have had a bumper crop of nuts. Mast is an old word referring to all of the nuts in the forest including acorns, beechnuts, butternuts and walnuts.
Why are there so many acorns this year 2021?
First, the production of a huge volume of a large seed like an acorn requires a lot of resources from the tree. This level of production may not be possible for the tree every year. Trees allocate energy to several different functions, so committing large amounts of energy to one area could mean deficits in others.
Why is it called beech mast?
Beech mast may refer to: The nuts of the beech tree (Fagus) A season of high seed production by the southern beech (Nothofagus)
How often do mast years occur?
two to five years
“Mast years” occur in irregular cycles of two to five years. An abundance of acorns is often said to augur a bad winter, the theory being that the squirrels know somehow that they need to stock up. The Farmers’ Almanac explored that hypothesis, and, to judge by the answers, it’s a bad winter every year.
Why do oak trees drop 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.
