Habitat:
This tree tolerates a wide range of soils but prefers rich, deep, well-drained,
loamy soils. It often dominates dry upland woods and, once established,
can tolerate drought conditions. It also occurs on moist slopes, though
less abundantly.
Diseases: Insect pests include the white oak borer and leaf miner. This species is subject to anthracnose fungus which causes severe defoliation especially of the lower half of the crown, but it is resistant to oak wilt disease fungus. Root rot can cause extensive dieback of major limbs. Like the pin oak and scarlet oak, this tree is sensitive to pollution and soil compaction.
Distribution: The white oak is hardy to zone 3 and native to the eastern US from southern Canada to northern Florida. In Iowa, this species is native as far west as the Cedar, Raccoon and Nodaway rivers; it also grows in the north-central (Pilot Knob) areas of the state.
