Sourwood is narrowly distributed (8.1% of area), common, dense, and with low IV, associated primarily with the southern Appalachian region. The highly reliable model suggests a slight decrease in suitable habitat (though still classed as 'No change' because it occupies <10% of the eastern US) but it also shows an expansion of territory to the northeast especially under RCP 8.5. However, the SHIFT model largely limits those northern locations from being naturally colonized within 100 years. It is also highly adaptable to a changing climate so that we provide an overall rating of good for the species to cope into the future.
