This book is a vital reference for the national status of threatened species, particularly for rare or poorly known species, and is the most up-to-date list for conservation purposes. This edition includes a significant number of endangered and vulnerable taxa not yet considered for inclusion on either the Australian and New Zealand Environment and Conservation Council list or the Commonwealth's Schedule 1.

Now in its fourth edition, this list has expanded from 3329 taxa in 1988 to now include 5031 taxa. In addition to the overall changes in the number of taxa listed, there have been at least 3270 amendments to data for listed taxa. The list and associated coding system was developed and has been maintained by CSIRO since 1979 and lists taxa that are presumed extinct, endangered, vulnerable, rare or poorly known at the national level.
