See SEEA-CF, s. 5.8.4 for advice on methods for estimating the monetary value of the timber resource asset (as opposed to the value of the physical flow of natural inputs from the asset). Note that valuation for natural timber resources should only include those timber resources available for wood supply (e.g. excluding conservation plantings).

Example methods / guidance / references

What are tiers?

Tier 1

Estimate using own judgement and observations

For example, methods for measuring volume of timber resources can be found in Abed and Stephens (2003), ‘Tree measurement manual for farm foresters‘.

Tier 2

Estimate using third-party professional estimates or public data

Tier 3

Model or measure based on site-specific surveys/sampling, remote or in-field sensing, laboratory analysis, etc.

Example data sources

Internal records

Third-party data sources

Maps showing the locations of Australian forests, by type, are available at Forests Australia – Forest maps (select Interactive maps of Australia’s forests – Forests of Australia).

Site-specific measurements or model outputs

Data on area of Australian cultivated timber resources are available in the latest version of Australian plantation statistics.

Notes

Timber resources are defined as “the volume of trees, living or dead, and include all trees regardless of diameter, tops of stems, large branches and dead trees lying on the ground that can still be used for timber or fuel” (SEEA-CF 2012, para. 5.350). To be consistent with the SEEA Central Framework, the methods used to determine volume should reflect the volume that is commercially usable, taking into account local conditions and practices. The volume of timber resources is often referred to as the volume of ‘standing timber’, which can include dead trees or logs that are still useful for timber products or fuel.
