(En.)
Regrowth jarrah (Eucalyptus marginata Donn ex Sm.) and marri (E. calophylla R. Br. ex Lindl.) stands growing on private land or in State Forest are often well stocked with saplings and poles. Thinning these stands will increase tree growth and water yield in high rainfall areas and create a large volume of wood for utilisation. Fence posts and strainers are products that can be produced from thinnings. Treating the sapwood with a water-borne or oil-borne preservative is necessary to create a protective en
investigation. Costs based on preservative uptake are given and an economic analysis of producing 250 posts, indicated it would cost $2.50 to producing a treated 100 mm small end diameter under bark (s.e.d.u.b) fence post using on-farm treatment methods.
