Interpretation Guide
Swamp tupelo is narrowly distributed (5.0% of area), but dense with high IV found quite commonly in certain portions of the southeast lowlands, and this species is somewhat unique in that the current distribution is far larger than that mapped by Little in the late 1960's. It is medium with model reliability, low in adaptability (susceptible to drought, fire, and the specificity of environment for regeneration), and with small increases projected for suitable habitat such that we provide a ranking of poor for capability to cope. Nonetheless, SHIFT classes it as a potential infill species should conditions be appropriate.
Family: Nyssaceae
