Orlando forestry manager Andy Kittsley said there are "definitely a bunch more" acorns falling from the trees this year with the sound of the falling objects often mimicking heavy rain, the Orlando Sentinel reported Tuesday. Advertisement The exerts said the increased acorn production, known as a mast or bumper year, happens every few years, but no one has yet determined the cause. Michael Andreu, a forestry professor at the University of Florida, said it's possible the oaks are dropping more acorns due to nearing the end of their life span, while other experts said the acorn boom could be a natural way to ensure some of the acorns survive being feasted on by squirrels, deer and other animals. "It's a bumper year," said Kevin Wilkey of Kevin's Tree Service. "One comes every three or four years, and this happens to be the year."
