Floral regions
A large part of the state of Connecticut is covered with oak-hickory type central hardwood forest. This region was historically dominated by various oaks and chestnuts, but hickory replaced chestnut with the spread of the chestnut blight.
In the northwestern hills of the state, more northern-hardwood type trees are present.
