Bark thickness and bark volume of Pinus patula in South Africa

Abstract

In South Africa, tree volume tables and volume functions are usually based on the under bark stem volume. Many forest management studies, however, give the estimated over bark volume, in which case equations are required that estimate bark volume and possibly bark thickness as a function of DBH and tree height. This study deals with the evaluation of geographical regions and tree characteristics on bark thickness and bark volume of Pinus patula in South Africa.
