This JVAP publication reports a series of trials to determine the natural durability of timber produced from high priority species being grown in farm forestry and low rainfall areas. The results will expand the market value of the wood product, thus enhancing the economic and environmental benefits of commercial farm forestry, and reducing the reliance on chemical preservative treatments for which at times there are environmental concerns.
This information will assist tree growers in low rainfall areas. Growers will be able to determine which species and age of tree will produce naturally durable heartwood, a feature that commands higher prices and acceptance in the market place, and in some export countries such as Japan.
