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.

Casuarius casuarius johnsonii

Casuariidae

Population type  

Endemic Australian taxon

IUCN Red List Status 2010  

Vulnerable A2c

Environmental Protection and Biodiversity Conservation Act Status  

Endangered

Reason if Threatened or Near Threatened  

Historical declines in habitat over the last three generations are thought to have caused a loss greater than 30% of the population in the last three generations (37.5 years), but the population is now almost stable.

IUCN Red List Status 2000  

Endangered A2c

Reason if changed in 2010  

Habitat loss has largely ceased through effective conservation of habitat

IUCN Red List Status 1990  

Endangered A2c

Reason if changed in 2000  

No change

C

Not applicable - population 500-2,500 mature individuals, continuing decline not observed or estimated, one subpopulation greater than 1,000 mature individuals, less than 95% in largest subpopulation

D

Not applicable - population greater than 1,000 mature individuals, greater than 5 locations

E

Not applicable - no population viability analysis undertaken
