Interpretation Guide
Shumard oak is sparely distributed (2.3% of area), with low IV throughout the southern half of the eastern US. Its low reliable model suggests some increase in suitable habitat (though still classed as 'No change' because of <10% area) in the central portion of the US, especially under RCP 8.5. However, the SHIFT model largely limits those new habitat locations from being naturally colonized within 100 years, though some expansion into this region has possibility.It is rated as highly adaptable and its overall capability as good.
Family: Fagaceae
Guild: persistent, large-seeded, advance growth dependent
