Age-diameter relationships for sugar maple (Acer saccharum) derived from previous studies and analysis of FIA site trees in North America: Michigan (MI), managed stand with several selection harvests ([24], Table 1); Wisconsin (WI), managed stands, selectively harvested ([25], Figure 1, diameter measured from top of cut stump); New Hampshire (NH), old-growth stand ([26], Table 1, diameter measured at top of root swell); FIA, site trees from New York FIA database (this study); New York (NY), uneven-aged managed stand, Allegheny Plateau ([27], Figure 2).
