Interpretation Guide
Sweetbay is a narrowly distributed (4.9% of area), sparse, low IV, but fairly common species in the southern seaboard (Gulf and southern Atlantic states), and its medium reliable model suggests an increase in suitable habitat (though still classed as 'No change' because of its narrow range). It is also ranked as moderate (but on the high end of moderate) for adaptability. Its overall ranking for capability to cope is fair, and SHIFT classes it as a decent species for infilling.
Family: Magnoliaceae
Guild: opportunistic, dispersal limited (large-seeded)
Functional Lifeform: small to medium-size evergreentree or shrub
