City of Clio issued the following announcement on Oct 16.
TREES ACROSS THE STATE are producing a bumper crop of acorns, black walnuts and cones this fall, littering sidewalks, streets, patios and yards.
The phenomenon is called a “seed mast,” when trees and shrubs produce a large amount of seeds when compared to other years.The cause of this particular seed boom is rooted in the relatively dry weather of late spring and summer of 2020, which was stressful to many trees, causing them to increase production of flower and cone buds in response.
