Many non-marine invertebrates are inherently vulnerable because they have very small ranges. Nevertheless, narrow range taxa are generally not being considered in conservation planning because of a lack of information regarding their taxonomy and distribution. Most of the existing information lies in museum collections and, if electronically databased, these data can be made accessible for use in biodiversity assessment and a wide range of other research programs. The Australian Museum has embarked on a Narrow Range Endemics Program based on the collection data for a range of non-marine invertebrate taxa. These data will be used to determine areas (“hotspots”) important for narrow range species in New South Wales. Protocols and criteria used in the program are briefly described and potential applications discussed.
