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.

Thalassarche cauta

Diomedeidae

Population type  

Endemic Australian taxon

IUCN Red List Status 2010  

Vulnerable D2

Environmental Protection and Biodiversity Conservation Act Status  

Vulnerable

Reason if Threatened or Near Threatened  

Occurs at only three locations the smallest of which faces a plausible future threat from competition with Australasian Gannets Morus serrator and rough weather.

The loss of this breeding location could render the status as Endangered B2ab(iv) but, when no longer occupied, this species would again become Vulnerable D2, or even Least Concerned if no plausible future threat to the remaining two islands can be established. Therefore retained as Vulnerable. Losses from fishing bycatch are not known to be reducing the population.

IUCN Red List Status 2000  

Vulnerable D2

Reason if changed in 2010  

No change

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

Not applicable - AOO less than 250 km², 3 locations one of which could be lost but is still occupied so this criterion not triggered

C

Not applicable - population greater than 10,000 mature individuals

D

Vulnerable - no more than 5 locations with plausible future threat

E

Not applicable - no population viability analysis undertaken
