This datatable is part of the GLBRC Annual Net Primary Productivity dataset. This dataset contains the aboveground biomass data. Annual net primary production (ANPP) data is measured at peak biomass for a given treatment. Additional ANPP measurements are made where appropriate such as occasional destructive harvests for poplar. See the ANPP protocols for descriptions of the sampling and measurement methods for each of the treatments. Below ground net primary production (BNPP) are available for these same sites.
