This data contains stem diameter, height measurements, basal area and above ground living biomass calculations for the Gingin Banksia Woodlands in Western Australia.

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.
Lineage
Tree survey:
The 1 ha plot was divided into 100 subplots (10 x 10 m). All individual stems ≥ 10 cm diameter at breast height (1.3 m) were mapped within each 10 x 10 m subplot. Heights are recorded to the nearest 1 metre for each measured stem and are recorded as the length of the stem from ground to highest leaf, not height above ground level.
Biomass calculation:
Above-ground biomass was calculated for each stem >10 cm diameter at breast height using published using either generic or species-specific allometric equations (source):
Banksia species (Eamus et al.,2000)
Eucalyptus todtiana (Paul et al., 2013)
Melaleuca sp (Paul et al., 2013)
Nuytsia floibunda (Paul et al., 2013)
