Abstract

    A summary of the latest USDA Forest Inventory and Analysis data for the state of Vermont. The network of randomly distributed inventory plots are designed to capture broad temporal changes in the condition of the nation’s forest resource. Spatial coverages of species distribution, extent of forest cover and biomass compliment the yearly data summaries to capture an unbiased estimated of the state of Vermont's forests.

        • Method Description: Plots are designed to cover a 1-acre sample area, though not all trees in the plot are measured. Recent surveys use standard fixed-radius plot, while earlier inventories used mixtures of fixed-radius and variable-radius (prism) plot design

        • Method Description: Plot locations are 'fuzzed and swapped' to protect privacy and plot integrity in accordance with Federal laws. 'Fuzzed' plots are generally within 0.5 miles of original plot center, and plots where data was 'swapped' are generally similar in nature. See FIA manual for full details

        • Method Description: The standard plot consists of four 24.0-foot radius subplots (approximately 0.0415 or 1/24 acre), on which trees 5.0 inches and greater in diameter are measured. Within each of these subplots is nested a 6.8-foot radius microplot (approximately 1/300th acre) on which trees smaller than 5.0 inches in diameter are measured

        • Method Description: Conditions are defined by changes in land use or changes in vegetation that occur along more-or-less distinct boundaries. Reserved status, owner group, forest type, stand-size class, regeneration status, and stand density are used to define forest conditions. In older plot designs, plot center or subplots locations were rearranged such that the entire plot sampled a single condition, while in the current design, different conditions are “mapped” on the same plot.

      • Field attributes
        • Method Description: In addition to attributes that are collected in the field, FIADB includes attributes that are populated in the office. Examples of field attributes include tree diameter and height, and slope and aspect of the plot and subplot. Attributes that are populated in the office include assigned attributes, such as county and owner group codes, or computed attributes, such as tree and area expansion factors, and tree volumes

      • Standards and guidelines
        • Method Description: Forest inventory plans are designed to meet sampling error standards for area, volume, growth, and removals provided in the Forest Service directive (FSH 4809.11) known as the Forest Survey Handbook (U.S. Department of Agriculture 2008). These standards, along with other guidelines, are aimed at obtaining comprehensive and comparable information on timber resources for all parts of the country
