Anyone with oak trees growing in their woodlots probably has noticed an extraordinary amount of acorns on the ground this fall. The vast majority of trees in a particular species will have a fantastic crop all across the UK in the same year. A generally accepted theory for the reason behind masting is that of predator satiation; in non-mast years, low crop yields keep predator populations low, meaning that the frugivores will be unable to consume the bumper crop produced during mast years, ensuring seeds have a chance at germination during spring months. It’s too early to tell for sure yet, but the records so far this autumn suggest it’s an exceptionally good year for acorn crops. Reply.

Research suggests that mast years happen every 5 to 10 years. The synchronisation of mast years of trees of the same species is thought to increase the odds of viable offspring production through maximising their reproductive potential in a process known as pollen coupling; trees that are out of sync, meanwhile, are removed from the gene pool. The following year, the trees will bear little to no fruit due to the abundance of energy required to produce the previous year's … Woodland Trust (Enterprises) Limited, registered in England (No. But Ostfeld’s research has connected acorn-heavy years to a much less attractive outcome for humans: an increase in Lyme disease.
