butternut (Juglans cinerea)
Model Reliability: Current Distribution Only
Current Distribution Only
The model reliability (ModRel) for butternut was too low (< 0.14), therefore only the current Forest Inventory & Analysis distribution is shown.

Interpretation Guide
Butternut is very sparse (0.9% of area), with hardly any cells lighting up as present within FIA plots (even though Little shows a wide distribution across the northern half of the eastern US), and it has been declining due to canker disease. It's model was too unreliable to use for future habitat estimates. It also has low adaptability, so it may have additional issues with the future climate.
Family: Juglandaceae
Guild: opportunistic, short lived intolerant
Functional Lifeform: small to medium sized deciduous tree
