Compilation of a list of threatened invertebrates: the Tasmanian experience

Abstract

The Invertebrate Advisory Committee was convened in 1992 to produce a list of rare and threatened non-marine invertebrates for Tasmania. The interim list, completed in 1994, was prepared for inclusion in threatened species legislation and to ensure consideration was given to invertebrates in forest harvesting operations. 175 species from seven phyla, eight classes and 25 orders were listed according to IUCN categories. In some cases entire taxonomic groups had to be ignored due to lack of information, hence the interim status of the list and the need for regular review. Some of the problems encountered during the compilation of the list are outlined. Lists of threatened species can be used as a tool to further other habitat, ecosystem or multi-species approaches to invertebrate conservation.
