Life Cycle of Oak Trees

Life Cycle of Oak Trees. Dendrologists—scientists who study trees, shrubs and vines—divide oak trees into two basic groups. One is the white oak group and the other is the red oak group.

Dendrologists—scientists who study trees, shrubs and vines—divide oak trees into two basic groups. One is the white oak group and the other is the red oak group. One easily observable difference is that white oak leaves have lobes that are rounded, while the lobes on red oak leaves are bristle-tipped. And the two groups have slightly different life cycles.
Flowering is part of an oak tree's life cycle. The flowers on oak trees, though, are not the showy kind and the average observer may not even recognize them as flowers. Among other factors, botanists categorize flowers by how they are pollinated. Some flower types are insect-pollinated, while others are pollinated by wind. Oak trees have flowers that are wind-pollinated. In other words, rather than an insect actively carrying pollen from the male flower to the female, the pollen simply drifts in the air. By chance, some of it will land on female flowers and pollinate them.
The fruit and seed of the oak tree is the familiar acorn. Once the oak tree has flowered and wind has scattered pollen and pollinated the female flowers, the acorn begins to develop. Oak trees in the white oak group have acorns that mature and are ready to germinate in one season. The white oak tree flowers in the spring; its acorns develop during the spring and summer, then drop and are ready to sprout in the fall of that same year. Acorns developing on a tree in the red oak group grow and develop just as those of the white oak but are not mature and ready to sprout until after winter and into the following year.
Unlike the seeds of a tree like a maple, acorns are not carried by the wind, except perhaps to a slight degree in an extreme windstorm. Instead, they merely fall from the tree and generally land very close to the parent tree. Animals, especially squirrels, scatter the acorns. The occasional acorn overlooked by its rodent hoarder may, in this way, sprout and grow some distance from the parent tree. It’s worth noting, too, that acorns that fall into a stream or river may be carried considerable distances from the parent tree.
Given favorable soil conditions, an acorn that has survived the numerous potential damaging agents—including being eaten by animals or attacked by insects—may send down its tap root, send up its shoot and begin its life as a young seedling.
