- Purpose
- This dataset records tree diameter and height data used to calculate above-ground biomass across vegetation types in Australia. This data is important for mapping and monitoring changes in plant growth, carbon storage and terrestrial energy fluxes.

- 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.
Resource lineage
- Statement
- Tree survey:<br> All trees >10 cm diameter at breast height in four 1 ha plots within the Great Western Woodlands site were mapped in 2012. Stem diameter was measured at breast height (1.3 m) with measuring tape. Tree height was measured using Nikon Forestry 550 hypsometer. <br> Biomass, basal area and sapwood calculation:<br> Standing above ground biomass (kg) was calculated using allometric regressions published in: Jonson J. H., Freudenberger D. (2011) Restore and sequester: estimating biomass in native Australian woodland ecosystems for their carbon-funded restoration. Australian Journal of Botany 59, 640-653. Basal area (m2) for each tree was calculated as: pi/4*DBH^2. Sapwood area (m2) for each tree was calculated as: 0.42*exp(-0.003*10*DBH)*basal area. Biomass of dead stems was calculated using a reduction factor of 85% of alive biomass (Bennett et al., 2013) Note: both alive and dead stems are included in the site level calculation of above ground woody biomass.
