[The oak is monoecious, with both male and female flowers on the same plant (old and new growth). Males produce pollen on long stiff catkins – females produce the eggs and are the silky part of the flower. The pollen is generally transferred thru wind dispersion. The seeds (acorn) grow out of the female flower in a woody brown cap. This cap is not a part of the actual acorn, but a cover, and will vary in size and coverage depending on the oak species. Maximum acorn production usually begins to occur at around 20 year old oaks, but is common for trees to be 40-50 years old before good production. “Mast years” are the years when acorn production is at its highest levels.]
Collected opinions or stats about acorn production:-Acorn production is cyclical, with some trees producing acorns nearly every year, and others rarely ever producing.
[The ODNR reminds us that acorns are a viable source of food for more than 90 forest wildlife species, and can affect hunting plans as well. Deer, turkeys, and squirrels will be more concentrated near areas of high crops of acorns. In areas with poor acorn production, wildlife will be feeding around agricultural areas and forest edges.]
