Timber resources can be divided into those that are available for wood supply and those that are not, such as timber resources in protected areas. They can also be divided into natural and cultivated timber resources.

Cultivated timber resources – Monetary value

Units

$

Example approach

Multiply estimated physical flow by market price per unit

Example methods/guidance/data sources/references

Timber harvested records

Notes

The value of the asset can be estimated based on multiplying estimated total volume by average stumpage price across all maturities of timber. See SEEA-CF, s. 5.8.4

Notes

The value of the asset can be estimated based on multiplying estimated volume for each age class at maturity by stumpage price, discounted to present value and summed across age classes. See SEEA-CF, s. 5.8.4

Notes

The value of the asset can be estimated based on multiplying estimated total volume by average stumpage price across all maturities of timber. See SEEA-CF, s. 5.8.4. Note that valuation for natural timber resources should only include those timber resources available for wood supply (e.g. excluding conservation plantings).
