Description: Close-range remote sensing was used to estimate biomass of forest ground flora in Arkansas. Digital images of a series of 1-m² plots were taken using Kodak DCS760 and Kodak DCS420CIR digital cameras. ESRI ArcGIS™ and ERDAS Imagine® software was used to calculate the Normalized Difference Vegetation Index (NDVI) and the Average Visible Reflectance (AVR) index for each plot. Regressions, developed to estimate green and dry biomass from the NDVI and/or AVR values, explained 30-40 percent of the variation. A vegetation mask and/or different independent variables are needed to improve the regression models.
