What is mast fruiting?

Mast fruiting, or masting, is a phenomenon where certain tree species, particularly in the family Fagaceae (such as oaks and beeches), produce an abundant crop of seeds or fruits in a synchronized manner over irregular intervals, often spanning several years. This strategy enhances the likelihood of seed survival by overwhelming seed predators during mast years, thereby increasing the chances of regeneration. The timing and frequency of mast fruiting can be influenced by environmental factors, such as climate and local conditions.
