Assessment Date | 2007/05/01 |
Assessor(s) | D. Raimondo |
Justification | A population reduction of at least 50% is estimated based on the local extinction of known subpopulations and habitat loss to urban expansion, agriculture and alien plant invasion in the past 140 years (generation length >50 years). EOO<1800 km², small, severely fragmented remaining subpopulations continue to decline. |
