Wombat Stringybark Eucalypt Coarse Woody Debris Data 

This data contains diameter, volume and biomass measurements of all coarse woody debris pieces within the core 1 ha plot at the Wombat Stringybark Eucalypt site in 2015.

Coarse woody debris (CWD) is a fundamental component of forested ecosystems, providing habitat for organisms and play an important role in nutrient cycling and carbon storage. 

Coarse woody debris sampling:
Coarse woody debris (CWD) was sampled at the Wombat Stringybark Eucalypt site in 2015. Coarse woody debris at the core 1 ha was assessed over two 100 m long transects (running North – South and East – West), recording diameter and state of decay. The diameter of CWD pieces where they intersected the transect were recorded, following the method described in Van Wagner (1968). Void space percentage for each CWD was not recorded and was assigned a "zero". Wood density values based on decay class were taken from Burton et al. (2021)
Calculation of coarse woody debris volume and biomass
CWD volume for each transect was calculated using the formula outlined in Van Wagner (1968), where volume =3.1415^2/(8*length of transect)*diameter*1-void space^2. CWD biomass for each transect was calculated by using the formula described in McKenzie et al (2000), where biomass = volume*wood density. The mean CWD volume and biomass values were then calculated at the site level.
