This data contains stem diameter, height measurement and above ground living biomass calculations for a Eucalyptus dominated woodland in 2015. Diameter and height measurements for stems ≥10cm diameter at breast height were sampled within the core 1 ha plot within the Karawatha Peri-urban site.

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:
In 2015, the diameter at breast height and height were measured for all individual stems ≥ 10 cm diameter at breast height (1.3 m) within the core 1 ha plot. Diameter at breast height was measured at 1.3 m above the ground, with the tape placed perpendicular to the length of the trunk. Height was measured by sighting on a measurable point as close to the apex of the canopy as possible. Health and growth form were allocated based on the AusPlot Forests Survey Protocol Manual v 1.0.
Biomass calculations:
Allometric equations were chosen from Williams et al (2005). This was then corrected due to the transformation from logged biomass (LN biomass) to biomass. 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.
