Did you know?
Pignut hickory (Carya glabra), and sweet pignut hickory (Carya ovalis) are two species of hickory that occur within coastal oak-hickory forests. These two species of hickory are actually very difficult to distinguish from each other most of the year. The main difference between the two species is the husk of the fruit. "The fruit of pignut hickory is pearshaped and the husks splits only about halfway down. This last feature is the only trustworthy one, since the other characteristics intergrade" (Harlow 1957).

State Ranking Justification [-]
There are less than 10 documented occurrences statewide. These occurrences have good viability and are protected on private or public conservation land. The community is restricted to interior portions of coastal lowlands in Suffolk and possibly Nassau Counties and is concentrated on knolls and mid to upper slopes of moraines. The acreage, extent, and condition of coastal oak-hickory forests in New York is suspected to be declining.
