There is zero acorn mast in coastal Biddeford this Fall. I first noticed the low mast last week. I asked the campus grounds crew and they noticed the same thing. Last year there were so many acorns on campus that students were slipping and falling down while walking between classes. I rode in this morning and carefully looked at 12 miles of largely oak-lined streets. I did not ride over a single stretch of pavement with acorns. Hickories do seem to have mast, but they are fairly low in abundance. I cannot imagine how caching animals are going to survive this winter….or even fatten up for that matter. Heavy snows last winter, although not terribly cold, were tough on squirrels. And that is with a huge mast year to prepare and cache.
