Please note, this National Red List website contains a subset of data whilst we transition to national focal point driven data uploads. We thank you for your patience with this and welcome national contributors to get in touch to update their national dataset. Terms of Use including citation guidance are found here.

The previous dataset is available via: https://archive.nationalredlist.org/. This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Assessment rationale/justification
Assessments against all criteria give no reason to consider it threatened. 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; EOO far exceeds the 20,000km2 VU threshold for Criterion B and the number of locations exceeds five, exceeding the Criterion D2 threshold. There is no information on population size to assess against Criteria C and D1 and no life history models to inform assessments against Criterion E. The AOO is below the Criterion B threshold but the number of recent locations exceeds 10 and there is no evidence of continuing decline, fragmentation or extreme fluctations in the population. None of the estimates approach the thresholds sufficiently to suggest NT might be an appropriate categorisation.
