sugar maple (Acer saccharum)

 Interpretation GuideView the guide to reading the interpretive narrations

Sugar maple is widely distributed (21.3% of area), dense, and with high IV across much of the northern 2/3 of the Eastern US. It ranks fourth in overall abundance across the eastern US, behind loblolly pine, red maple and sweetgum. It rates as highly adaptable although under persistent drought or other stresses, it would likely decline. In contrast to our earlier models which showed substantial habitat decline in the south under harsh climate change, the species is modeled to decline only modestly, so we rate it with a very good capacity to cope, and to be a good infillThe species is projected, according to SHIFT, to be a good species to plant to ‘fill in’ suitable habitats, most often in the general proximity and gaps present in the current range of the species. species (according to SHIFTMigration model that calculates the likelihood of colonization, based on current abundance over an approximately 100-year time period period to roughly intersect the future suitable habitats predicted by DISTRIB-II).
