Interpretation Guide
Hackberry is similar to sugarberry but more widely distributed (14.1% of area) and slightly more northern across the western half of the eastern US; it is an abundant species with high adaptability (drought tolerant) and a medium reliability model suggesting increasing habitat in future. These yield an overall rating of very good for capability to cope, plus a high recommendation from SHIFT as an infill species.
Family: Ulmaceae
Guild: opportunistic, fast-growing understory tolerant
Functional Lifeform: small to medium-size deciduous tree
