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.

Papasula abbotti

Sulidae

Population type  

Endemic Australian taxon

IUCN Red List Status 2010  

Endangered B2ab(ii,iii,v)

Environmental Protection and Biodiversity Conservation Act Status  

Endangered

Reason if Threatened or Near Threatened  

Occupies only 25 km² at a single location with a continuing decline likely in area of occupancy, area and quality of habitat, and number of mature individuals, largely from the ongoing effects of past clearing for mining

IUCN Red List Status 2000  

Critically Endangered A3ce

Reason if changed in 2010  

Effective ant control applied

IUCN Red List Status 1990  

Endangered B2ab(ii,iii,v)

Reason if changed in 2000  

Proliferation of invasive ants

Current Eligibility against IUCN Red List Criteria  

.

IUCN Category

Criteria Eligibility

A

Vulnerable - population decline 30-49% over the last 3 generations (49 years) inferred from monitoring and deteriorating habitat quality

B

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

C

Vulnerable - population 2,500-10,000 mature individuals, suspected continuing decline, 100% in 1 subpopulation

D

Vulnerable - no more than 5 locations with plausible future threat

E

Not applicable - no population viability analysis undertaken
