The difference in classifications between jurisdictions, etc.

variety of classifications and is there any attempt to get a common,
agreed conservation status? What is the relationship between the EA
classification and "Garnett 1992"?
Hi Bob
Garnett & Crowley (2000) - The Action Plan for Australian Birds
2000 - is the latest published source for national conservation
status of birds. In that the Freckled Duck is considered to belong in
the IUCN category "Least Concern" at national level.
The listings under the Commonwealth/Federal EPBC Act 1999 are broadly
consistent with Garnett & Crowley, but not entirely. There are a
few more that might be eligible for EPBC listing, and I understand a
few are under consideration at the moment.
It's entirely logical that the national and state lists would regard
birds differently, because a number of species which are either/both
rare or threatened in Victoria for example might be much more abundant
and or secure when the national population is considered. The IUCN
criteria can be applied at various levels - global down to bioregion
(or even municipality) - and provide a fairly useful standardised means
of assessment for jurisdictions of varying level.
