Acorn Abundance Influences Behaviors of Ohio’s Wildlife

COLUMBUS, Ohio – The 2022 survey of acorn abundance on selected Ohio wildlife areas shows an average of 39% of white oaks and 37% of red oaks bore fruit, according to the Ohio Department of Natural Resources (ODNR) Division of Wildlife. The long-term average for white oak production is 37%, and 54% for red oak production.“A mature oak tree can produce thousands of acorns, which in turn feed more than 90 of Ohio’s forest wildlife species,” said Division of Wildlife Chief Kendra Wecker. “Deer, turkeys, squirrels, ruffed grouse, blue jays, raccoons, woodpeckers, foxes, and more seek out and eat acorns throughout the fall and winter.”

Acorns come in two basic types: red and white. They are divided into these groups based on the type of oak tree. Red oak acorns take two years to develop, and the acorns are bitter, containing a large amount of the chemical tannin. White oak acorns take only one year to develop and have a sweeter taste. These differences cause periodic fluctuations in statewide acorn abundance. Low mast production years are a normal part of this cycle, and wildlife readily adapt to find alternative food sources.
