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

Interpretation Guide
Scrub, or bear oak is very rare in the northern Appalachians (0.2% of area) and the model is unacceptable for predicting future habitats. It does have medium adaptability to a changing climate.
Family: Fagaceae
