This data is a Lidar-derived estimate of the above ground biomass (AGB) of trees. It was developed by the Minnesota Department of Natural Resources using Lidarthat was collected in 2019. It represents AGB in pounds per acre for all trees of five inches or larger dbh. Forest Inventory Analysis methods were used to estimate species-specific individual tree biomass that were then summarized to plot level to obtain total aboveground biomass on per acre basis. The field sample data were collected over 120 plots of one-tenth acre size, and for each of the plots more than 40 Lidarmetrics were derived based on the co-located point cloud to fit a linear regression model that were ultimately applied over the entire area of interest using selected Lidarpredictors at 20-m spatial resolution. This information can provide foresters a better understanding of the landscape and how it should be managed, as well as serving as an estimate of carbon on the landscape.
