Calperum Mallee Stem Diameter, Height and Aboveground Woody Biomass Data 

This data contains stem diameter, height measurement and above ground living biomass calculations for a Mallee Eucalypt dominated woodland from 2015 - present. Diameter and height measurements for stems were sampled within the core 1 ha plot within the Calperum Mallee site. 

We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. This work was funded by the Terrestrial Ecosystem Research Network (TERN), an Australian Government National Collaborative Research Infrastructure Strategy (NCRIS) project. 

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. 

Tree survey:
A vegetation survey was carried out at the core 1 ha plot at the Calperum Mallee site in 2015. Tree diameter at 10 cm above the ground and height were measured for all stems within the core 1 ha plot. The vegetation was mostly regrowth from lignotubers following near complete destruction on above ground biomass during a wildfire event on 17 Jan 2014.
Biomass calculation:
Aboveground tree biomass was estimated from above measurements using Eucalyptus-specific allometric equations as detailed in the following publication: Paul, K.I., Roxburgh, S.H., England, J.R., Ritson, P., Hobbs, T., Brooksbank, K., John Raison, R., Larmour, J.S., Murphy, S., Norris, J., Neumann, C., Lewis, T., Jonson, J., Carter, J.L., McArthur, G., Barton, C., Rose, B., 2013.
