American holly is sparsely distributed (6.0% of area), with low IV, across the southern states, and its medium reliable model suggests and increasing amount of habitat throughout that region (though still classed as 'No change' because it is found in <10%, or rare, within the eastern US). Its adaptability rating is moderate. It ranks as fair for its capability to deal with a changing climate.
