Warra Tall Eucalypt Eucalyptus obliqua Biomass Determination Data 

Destructive sampling of 47 Eucalyptus obliqua trees was carried out in the Warra Tall Eucalypt site to determine a range of biomass measures that can be used to inform allometric equations. 

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.

Selection of trees
47 Eucalyptus obliqua trees were selected by personnel from State Forests of NSW and Forestry Tasmania to reflect as closely as possible the range and quality of trees that are harvested during a commercial harvesting operation in that area.
Measurement of standing trees
The diameter at breast height was recorded for all trees.
Felling of the tree
Trees were felled using a chainsaw and the length of the tree and stump height (tree height) were recorded. The trees were then transported from the forest to the log dump by an excavator.
Measurement of felled trees
The crown was lifted by the excavator and placed on a platform placed on top of the weight bars to allow measurement of material shorter than the span between the weigh bars. The weight of full-length log (still with the bark on) was measured by placing on top of hardwood beams on the weigh bars to optimise load sharing. Some logs exceeded the capacity of the weigh bars; in those cases, they were either split or shortened and each component measured separately. The logs were then debarked by the excavator. The debarked log was then weighed the same way as the intact log. All log products had their lengths and diameters measured after being graded according to their end use. “Crown” was defined here as the uppermost part of the tree after the commercial log was cut. Portions of the crown were also assessed and graded as pulp material. The length of the crown was obtained by subtracting the original sum of log product lengths from the original tree height.
