Abstract
SUMMARY Poles from thinnings are of considerable economic importance to forest management. They can also contribute to regional development and conserve foreign exchange by avoiding imports of wood poles or costlier substitutes. Planned forest management is essential to meet both short and long term demand for poles and to avoid the introduction of substitute materials. Production of poles may be increased by the use of rapid-growing exotics and supply may be improved further by preservative treatment of poles from species of low natural durability. Difficulties are sometimes experienced in controlling drying degrade in poles from some timbers before preservative treatment but may usually be overcome by sound seasoning practices or special drying techniques. Standards of acceptance for poles should be based on criteria relevant to their service requirements.
