Interpretation Guide
Pignut hickory is a common and widely distributed (15.8% of area) species across much of the eastern US, especially the middle latitudes. It has relatively low IV but is commonly found on FIA plots. Our models of moderate reliability suggest a small increase in habitat may occur under climate change, including into the far north (primarily under RCP 8.5). The SHIFT model, however, limits natural migration from reaching those northerly zones within 100 years. Rated as moderately adaptable, its current abundance pushes its overall capability to cope with a changing climate as fair (4.5) to good (8.5).
