6. Supporting evidence

[A] ASFB CATEGORIES

Evidence to support proposed status:

(Evidence must support the criteria outlined in the relevant category. Cite published papers, reports etc. wherever possible. Include details of past and present distribution in map form, if possible. Is the decline in distribution continuing? What are the threats? What are the habitat requirements of the taxon?)

6. Supporting evidence (continued)

[B] IUCN RED LIST CATEGORIES

Refer to attached explanatory sheet for a summary of IUCN categories. However, classification should not be undertaken without reference to the IUCN Red List Categories booklet (1994). State Threatened Fishes Committee members will have copies of this publication. Note only one of A to E (below) is necessary to list a taxon. However, if information is available on more than one category, it should be recorded.

A. Declining population

(state particular criterion/criteria used eg. Critically Endangered: A1(b) or Endangered: A2 etc and document evidence)

B. Small distribution and decline or fluctuation

(state particular criterion/criteria used as above and document evidence)

C. Population estimation - small population size and decline

(state particular criterion/criteria used and document evidence)

D. Population estimation - very small or restricted

(List criterion used eg. Critically Endangered, Vulnerable etc., and document evidence)

E. Quantitative analysis - probability of extinction

(state particular criterion used eg. Vulnerable E and document evidence)

Lower Risk

(if taxon considered: Conservation Dependent, Near Threatened or Least Common. Provide evidence)

Summary

(eg. Critically Endangered A2(c), (d), C2(a) etc. Note if adequate assessment of risk cannot be made based on observation, inference or projection it should be listed as Data Deficient (DD))

7. Threatening processes

(tick the key threatening processes for the taxon nominated)

• Introduced species
• Instream habitat removal / destruction
• Riparian vegetation removal
• Sedimentation
• Water extraction / Flow regulation

• Reduced water quality
• Overfishing / collection
• Barriers to movement
• Loss of genetic diversity
• Other
