Family: Walnut Family (Juglandaceae)
State Protection: Threatened 
listed species are those with: 1) 6 to fewer than 20 extant sites, or 2) 1,000 to fewer than 3,000 individuals, or 3) restricted to not less than 4 or more than 7 U.S.G.S. 7 ? minute topographical maps, or 4) listed as threatened by U.S. Department of the Interior. Federal Protection: Not Listed State Rarity Rank: S2
A State Rarity Rank of S2 means: This plant is threatened/imperiled in New York because of rarity (typically 6-20 populations or few remaining individuals) or is vulnerable to extirpation from New York due to biological factors. 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.
| Short-term Trends | [-] |
Six new occurrences have been found in the last 20 years and six of the 12 historical records have been relocated.
| Long-term Trends | [-] |
The same number of occurrences are presently known as were known from historical records although some large stands of the tree were probably reduced in recent history.
