While assessments of mature trees provides information about the current condition of Vermont’s forests, the density of saplings give details about the likely hardwood composition in the future. Hardwood regeneration is a measure of the density of saplings per acre, inventoried annually on Forest Inventory and Analysis (FIA) plot data. Per FIA protocol, plots are reassessed every 5 years until 2014, and every 7 years since then. A hardwood seedling is classified as a small tree less than 1" in diameter and greater than 12" in height1. Here, a dominant component of the Northern Hardwood Forest, and an ecologically and economically important species, sugar maple (Acer saccharum), was used as a proxy for all hardwood species regeneration. The current year is scored as the distance between 0 and the maximum value, scaled to be between 0 and 1 using a 5-year moving window.
