The Certify UI allows you to add tree measurements under project areas of your biosphere project. Tree measurements are used to estimate above-ground biomass (AGB) within each field plot, which in turn helps quantify the carbon sequestered in the project area. You can bulk upload tree measurements in Certify UI using the provided template and example. Each tree sample must have a unique reference ID, be linked to a specific field plot, and use one of the predefined tree type codes below. Either truncated or full code is accepted.
