Blackgum is widely distributed (21.6% of area), dense, though low IV across the central and southern portion of the region, and the medium reliable models suggests small to large increases in habitat, including way up into New England, depending on scenario. However, the SHIFT model largely limits those northern locations from being naturally colonized within 100 years, though a fairly large northward expansion has at least some possibility. It is rated as highly adaptable, and with an overall rating of very good for capability to cope with a changing climate.



Family:  Nyssaceae

Guild: opportunistic, dispersal limited (large-seeded)
