VALUATION OF…

Timber & Forestry Plantations

Land and standing timber valued as separate components — an inventory-based asset with rotation-length horizons.

Methodology

Forestry property is valued in two parts: the land at its underlying value, and the standing timber as a biological asset whose worth derives from its species, age-class distribution and the volumes it will yield at harvest. The accepted approach to the timber is a discounted cash flow across the rotation, built on a verified compartment inventory — species, age, stocking, site quality and expected yields — at defensible mill-delivered prices net of harvesting and transport. Sales of plantation properties provide the market check, though they require careful analysis because each sale embeds a different age-class profile.

Under the Big Five framework the income-generating unit is the productive compartment, and the age-class distribution is the profile of the income stream: a normal distribution yields regular harvest income, while a skewed one concentrates income in particular years and may leave long unproductive gaps. Normalisation must deal with growth risk, fire and pathogen risk, and the costs of silviculture, fire protection, roads and rehabilitation across the full rotation. The long horizon places unusual weight on the discount rate, and the reasoning connecting the risks identified to the rate adopted should be explicit.

The dominant drivers are site quality and species, the age-class distribution, distance to processing capacity, and the security of the timber against fire — insurance status and protection infrastructure are evidence, not background. Two statutory notes belong in every forestry valuation: afforestation is a licensed water use under the National Water Act, which bears on both the lawful extent of planting and any expansion assumption; and growing timber not yet harvested is disregarded in municipal valuation of agricultural property, so a rates valuation and a market valuation of the same property are measuring different things.
