Interpretation Guide
White oak is widely distributed (28.6% of area, fourth behind red maple, black cherry, and American elm), dense, high IV, and abundant (fifth in FIAsum behind loblolly pine, red maple, sweetgum, and sugar maple) throughout much of the eastern US, with a medium reliable model predicting a small increase in suitable habitat, throughout most of the eastern US and up past the Canadian border (RCP 8.5), by century's end. However, the SHIFT model largely limits those northern locations from being naturally colonized within 100 years, though a fairly large northward expansion has some possibility. While it is susceptible to some insects and diseases, it is tolerant of drought and rates a high adaptability rating. Thus, its overall rating for capability is very good, and SHIFT identifies it as a very good species for infilling as well.
