About 200 biomass estimates for native vegetation are provided for contrasting locations throughout Australia based upon published and unpublished information. Discussion is provided in relation to maturity of the vegetation (i.e. change due to prior disturbance), accuracy of spatial location, and the size of the area sampled (plot versus stand) and hence likely representativeness of local conditions.
Much of the data do not meet the strict criteria specified by the Australian Greenhouse Office (AGO) in relation to these factors, and thus the data should be evaluated very carefully prior to their use to calibrate the modelled continental productivity surface produced by the AGO.
We recommend that additional robust verification data (derived from multiple inventory plots over several hectares) for a range of vegetation types along the biomass gradient, be collected to confirm the reliability of the calibration.
