Many BADM groups have a required and several optional STATISTIC variables. Specific examples of their use are given after an overview the variables basics. STATISTIC Basics BADM typically describe site-level descriptions and observations. The STATISTIC variables allow for full characterization of the reported information if desired. BADM groups, such as canopy height, LAI, soil chemistry,… More

Many BADM subgroups and groups have SPP and VEGTYPE variables, like DBH_SPP and DBH_VEGTYPE. Do not enter values for SPP and VEGTYPE variables together for the same observation, i.e., in the same row of your CSV file. SPP and VEGTYPE are mutually exclusive, optional variables.
