Did you know?
Chestnut oak is one of the important trees, along with sugar maple and red oak, that replaced American chestnut after the devastating spread of chestnut blight. The American chestnut was a common component in chestnut oak forests prior to the chestnut blight in the early 1900s. The blight was caused by an introduced Asian fungus (Cryphonectria parasitica) and by 1950, the once common chestnut was reduced to decomposing logs and small stump sprouts.

State Ranking Justification [-]
There are several hundred occurrences statewide. Some documented occurrences have good viability and many are protected on public land or private conservation land. This community has a somewhat limited distribution in the state and includes several very large, high quality examples. The current trend of this community is probably stable for occurrences on public land, or declining slightly elsewhere due to moderate threats related to development pressure.
