This paper examines the management of hollows in trees in the jarrah forest. In the first part of this paper we present a framework for development of strategies for the retention of hollow-bearing trees at the stand scale, and the information available for application of this process to the jarrah forest is reviewed. Whilst significant information in relation to many elements of the framework is available, there is currently insufficient information to conclusively determine the effectiveness of the strategies adopted for management of hollows in the jarrah forest. In the second part of the paper, we discuss the suite of strategies that are employed across spatial scales to conserve hollows in the jarrah forest. The strategies include: the establishment of formal conservation reserves and informal reserves; the introduction of fauna habitat zones dispersed throughout the forest available for harvest; maintenance of connectivity, landscape heterogeneity, and stand structural complexity within the harvest area matrix, through silvicultural constraints such as limits on the size of gaps, prescribing minimum basal area to retain, and the retention of marked habitat trees, large marri trees and unmerchantable trees on harvested stands. These strategies reduce the risk to hollow-dependent fauna from timber harvesting.
