In Arkansas, there are 30 native species of oak - more than any other tree. The most common types of oak in our state are white oak, red oak, and post oak. Southern Red Oak (Quercus Falcata or Quercus Shumardi) is more common than Northern Red Oak (Quercus Rubra) here in Arkansas. Both are of the red oak Family. The rare maple-leaf oak is only present at four sites in the world - all of these are in Arkansas. There are also non-native oaks that grow here.
Oak trees offer habitat, food, shelter, and shade for wildlife. Many species of caterpillar eat oak tree leaves. Acorns are an important food for squirrels, chipmunks, deer, turkeys, raccoons, and more. Animals also nest and live in oak trees.
For humans, oak trees offer shade and beauty. Their extensive root system stabilizes the soil. Oak roots and leaves also absorb excess rainwater. You may notice many tree leaves turning over in anticipation of a storm so they can take in the rain, because their "stomata" openings are on the underside of leaves.

Preventative Tree Care: How Does Pruning Reduce Storm Damage?
Allow for mulched space around trees to avoid competition from grass, and danger to tree bark from mowers and trimmers. Leave the leaves that fall in autumn. Avoid "mulch volcanoes" and overmulching. Learn more about mulching here.
Avoid herbicides and over fertilizing, but do test for pH balance.
Remember that young trees (0-3 years) need consistent moisture while developing roots. And even mature trees need watering during droughts.
Think about pruning starting in 2nd year to head off any developing problems. Find out more about pruning young trees and mature trees.
