The Eucalypt Crown Diebacks—A Growing Problem for Forest Managers

Abstract
A number of new and increasingly important diseases known as eucalypt crown diebacks have appeared in Australia's native forests during the past few decades. They pose problems for management in terms of yield reduction, tree mortality, deterioration of wildlife habitats, and damage to flora. They will enforce re-appraisal of forest management programmes in many places. This paper outlines what is known of their extent, causes, and the prospects for their control. It considers also how management practices might be modified to accommodate them.
