Global Rarity Rank: G5
A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
The edible nuts of the big shellbark hickory are the largest of any hickory. They are valuable food for many wild mammals, ducks, quail and turkeys. The nuts can be collected and eaten raw or used in desserts.

State Ranking Justification [-]
There are 14 known populations and seven historical populations. More survey work is needed to determine how many of these historical populations are still present. The populations range in size from a few trees up to 500+ trees. This tree is at its eastern and northern range limits in New York. It very likely has always been an uncommon member of the New York flora.
