Tumbarumba Wet 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 Tumbarumba Wet 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 Tumbarumba Wet Eucalypt Core 1 ha site in 2015. Coarse woody debris was assessed over 10 x 60 m long transects, recording diameter, state of decay and void space. The diameter of CWD pieces where they intersected the transect were recorded, following the method described in Van Wagner (1968). Wood density values based on decay class were extracted from samples collected at the site.
Calculation of coarse woody debris volume, mass 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.
