Seed Production and Dissemination
Good crops of swamp white oak occur every 3 to 5 years, with light crops during intervening years. The minimum seed-bearing age is 20 years, optimum age is 75 to 200 years, and maximum age is usually 300 years. Because the seed of swamp white oak is not dormant, it germinates soon after falling. Seed collections should be made soon after ripening in order to delay early germination. These acorns are difficult to store without germination or loss of viability occurring. Sound acorns have a germinative capacity between 78 and 98 percent. Gravity, rodents, and water are the primary dispersing agents (4,10).
