How to Identify Oak Trees

The oak tree has approximately 450 species. This slow-growing tree lives around 500 years and some have lasted over 1,000 years. Oaks are common in both hemispheres and flourish in temperate climates.

Instructions

1. Note the leaves of the oak tree. Depending on the species, the leaves have from five to eight lobes on each side. These trees are deciduous; their green leaves turn from yellow to brown in the fall. On the underside of some species there is a network of fine hairs stretching out from the stem.

2. Look at the knotty, twisted twigs of the oak. The branches grow at angles spreading out in every direction. The buds grow in groups at the ends of the twigs later in the spring than most trees with leaves. The buds grow approximately 6-inches long.

3. Recognize the physical characteristics of the trunk. The bark is deeply grooved and grayish in color. The circumference of an oak may be 6 feet or more. Depending on the species, the oak can grow between 60 and 100 feet tall. The span of the branches is often greater than the height, making them wonderful shade trees.

4. Take note that the oak tree produces both male and female flowers. Their fruit is the acorn that some animals use for food. The oak tree is susceptible to many pests, causing the leaves to look tattered and full of holes. The wood is said to be resistant to spiders, making it an ideal wood for building.

5. Examine the soil in which the oak tree grows. The oak does well in soil with much clay. It's an exceptionally hard-wooded tree; as it grows older, it often assumes a gnarled exterior. This tree is the state tree in six states and there are plants in other families that are called "oak," but are not related.
