Key to maps

reddot.png(red dots) core records, known to represent existing locations of focal taxa; in the case of intra-continental migrants, only records approximating the taxon’s breeding distribution are used.

orangedot(orange dots) non-core records, representing vagrant occurrences of the focal taxon obviously outside its usual range, or historical observations of a taxon known to be extinct at that location.

greydot(grey dots) records of other subspecies of the same species as the focal taxon; or in the case of intra-continental migrants, non-breeding records of the focal taxon not included as core records.

blueploy(blue polygons) minimum convex polygons underlying the locational records on the maps that depict each existing taxon’s Extent of Occurrence (EOO).

yellowpoly

(yellow polygons) areas formerly occupied by Extinct taxa.

 

redarrow(red arrows) the location of taxa with very small distributionsand known seabird breeding locations.

Maps were made using the Geoscience Australia Lambert Conformal Conic (GALCC) projection.

Population type  

Endemic Australian taxon

IUCN Red List Status 2010  

Endangered B2ab(iii)

Environmental Protection and Biodiversity Conservation Act Status  

Endangered

Reason if Threatened or Near Threatened  

The very small population is restricted to a very small AOO at very few locations. The recent series of large wildfires suggests a probable continuing decline in habitat

IUCN Red List Status 2000  

Vulnerable D2

Reason if changed in 2010  

Multiple large fires suggest a continuing decline in habitat quality

IUCN Red List Status 1990  

Vulnerable D2

Reason if changed in 2000  

No change

Current Eligibility against IUCN Red List Criteria  

.

IUCN Category

Criteria Eligibility

A

Not applicable - past, current or future population declines are thought unlikely to exceed 20% in any 3 generation period

B

Endangered - AOO less than 500 km², at no more than 5 locations with plausible future threat, inferred continuing decline in area and quality of habitat

C

Vulnerable - population 2,500-10,000 mature individuals, inferred continuing decline, 250-1,000 mature individuals in largest subpopulation

D

Vulnerable - population 250-1,000 mature individuals, no more than 5 locations with plausible future threat

E

Not applicable - no population viability analysis undertaken
