 Interpretation Guide


Pecan is a narrowly distributed (3.9% of area), sparse, but high IV species common in several southern species, concentrated in Texas and Oklahoma but extending into Illinois. Its model, of low reliability, shows a huge expansion of habitat, especially under RCP 8.5. However, the SHIFT model shows that only a very small portion of the projected suitable habitat could get colonized naturally within 100 years. Its adaptability is low, resulting in a poor (4.5) to fair (8.5) overall capability to cope with a changing climate. SHIFT does, however, score it to be a decent infill species.
