National Status
Status and Criteria
Endangered A2c; B1ab(iii)
Assessment Date
2009/07/29
Assessor(s)
T.J. Edwards & D. Raimondo
Justification
A population reduction of > 80% is estimated based on >84% habitat loss to wheat cultivation since 1940 (less than three generations of this long-lived resprouter generation length suspected to be 50 years). EOO <4000 km², seven locations are known through herbarium collections, but two are now locally extinct due to agriculture. Remaining subpopulations are declining due to alien plant invasions and overgrazing by livestock.
