Paperbark Maple (Acer griseum)

Paperbark maple was collected by E.H. Wilson and introduced to the United States in 1901. Using the growth rate calculator multiplied to the tree diameter of this specimen, the approximate tree age places it at or near the introduction date. Only recently has more germplasm been wild collected from this taxon allowing for greater genetic diversity in propagation. International Union for the Conservation of Nature (IUCN) lists Acer griseum as Endangered with a current population between 220 to 250 individual trees remaining in-situ (in the wild). Our champion tree factored with a circumference of 51-inches, 25-foot height, 19-foot crown spread totaling 80-points. This specimen can be seen in Section 67 flanked by two younger paperbark maple specimens.
