Assessment rationale/justification
Whilst there is no evidence of continuing decline, fragmentation or extreme fluctuations in the population, the low value for AOO, in conjunction with the eight recent locations, would otherwise suggest a status of VU under Criterion B, and hence a status of NT is considered appropriate. Otherwise, the estimated rate of decline in range over the last 10 years does not exceed the 30% decline required for qualification as VU against Criterion A; there is no information on population size to assess against Criteria C and D1; the number of locations exceeds five, exceeding the Criterion D2 threshold; and there are no life history models to inform assessments against Criterion E.
