Abstract

Conservation of forest genetic resources with particular reference to Eucalyptus species.

Abstract

The author illustrates the need for well-planned conservation strategies through consideration of the genetic history of 8 fast-growing plantation species in Australia. For six major plantation eucalypts (Eucalyptus camaldulensis, E. deglupta, E. globulus, E. grandis, E. regnans, E. tereticornis) and for Acacia mangium and Pinus radiata, an outline is given of known or likely origins of the first large plantations, present knowledge of genetic variation between populations, conservation status of remaining natural forests and current action for in situ and ex situ conservation. The genetic base of the first plantations was too narrow, and has been greatly expanded with recent seed collections in better provenances of remaining natural forests. Conservation of their genetic resources will permit continued infusions of new material in the future.
