Boyagin Wandoo Woodlands Stem Diameter, Height and Aboveground Woody Biomass Data 

This data contains stem diameter, height measurement and above ground living and dead woody biomass calculations for a remnant Eucalyptus Wandoo woodland from 2018 - present. Diameter and height measurements for stems were sampled within the core 1 ha plot within the Boyagin Wandoo Woodlands 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 Boyagin Wandoo Woodlands site in 2018. Tree circumference, diameter at breast height and height were measured for all stems within the core 1 ha plot.
Biomass calculations:
The biomass of each stem was calculated using published using either generic or species-specific allometric equations (source):
Allocasuarina humilis (Paul et al., 2013)
Banksia nobilis (Eamus et al.,2000)
Banksia sessilis (Eamus et al.,2000)
Eucalyptus accedens (Paul et al., 2013)
Eucalyptus drummondii (Paul et al., 2013)
Eucalyptus loxophleba (Paul et al., 2013)
Eucalyptus wandoo (Paul et al., 2013)
Melaleuca sp (Paul et al., 2013)
Santalum spicatum (Paul et al., 2013)
Xanthorrhoea preisii (Fensham et al., 2002)
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.
