- Supplemental Information
- The dataset comprises an amalgamation of two surveys. The first survey was done in the original 1-ha core plot (now referred to as the Flux Tower Plot). Subsequently, a second survey was done in a 60 x 100 m extension to the western edge of the original 1-ha. Data for the new 1-ha core vegetation plot comprised measurements made in the 60 x 10 m extension and the western-most 40 m of the original 1-ha plot. The 60m extension was done to avoid the extensive disturbance associated with the installation of the Warra Flux tower in the eastern-most 60m of the original 1-ha plot.

- Potential diameter and height outliers were assessed by looking at the absolute difference in 1) diameter and 2) height values for each individual stem between two measurement time points. If the diameter or height difference for an individual falls outside the 3rd standard deviation of the mean of that species, then it was flagged as a potential outlier.
Report
Result
- Statement
- All potential outliers were assessed by researchers who collected the data. Any value that was considered to be an outlier was removed from the final dataset.

- Statement
- Tree survey:<br> All individual stems ≥ 10 cm diameter at breast height (1.3 m) were mapped within the core 1ha plot. Diameter at breast height and plant height was recorded for all stems.<br> Tree volume calculations:<br> The volume of each stem was calculated using species species allometric equations. <br> Species volume allometric equations (source):<br> Acacia melanoxylon: (Forrester et al., 2004)<br> Dicksonia antarctica: (Beets et al., 2012)<br> Eucalyptus obliqua: (Forestry Tasmania inventory data)<br> Eucalyptus lucida: (Walker, B.

Carbon concentration for all other species is 0.5 (default value). <br> Carbon mass for Dicksonia antarctica was calculated using the following formulae: Carbon = 2.70E-3 * (DBH2 H)1.19 (Beets et al. 2012).
