Argentipallium spiceri (Spicer's Everlasting)

Advice to the Minister for the Environment and Heritage from the Threatened Species Scientific Committee (TSSC) on Amendments to the list of Threatened Species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act)

1. Scientific name, common name (where appropriate), major taxon group

Argentipallium spiceri (Spicer's Everlasting)

2. National Context

The species is endemic to Tasmania. The species is currently listed as endangered under the EPBC Act and the Tasmanian Threatened Species Protection Act 1995.

3. How judged by TSSC in relation to the EPBC Act criteria.

TSSC judges the species to be eligible for listing as critically endangered under the EPBC Act. The justification against the criteria is as follows:

Criterion 1 - Decline in numbers

There is no quantitative data available against this criterion.

Criterion 2 - Geographic distribution

The geographic distribution of the species is precarious for the survival of the species and is very restricted. The area of occupancy is 1m2 and extent of occurrence is 100m2. The species exists in a single location formerly being known from only one other locality. A decline in the species is likely due to the limited viability of a single specimen and vulnerability of small populations to stochastic disturbance events.

Therefore, the species is eligible for listing as critically endangered under this criterion.

Criterion 3 - Population size and decline in numbers or distribution

The total number of mature individuals is very low, there being a single mature individual at one location. A decline in the species is likely due to the limited viability of a single specimen and vulnerability of small populations to stochastic disturbance events.

Therefore, the species is eligible for listing as critically endangered under this criterion.

Criterion 4 - Population size

The number of mature individuals is extremely low, there being a single known mature individual recorded in dedicated surveys.

Therefore, the species is eligible for listing as critically endangered under this criterion.

Criterion 5 - Probability of extinction in the wild

There is no quantitative data available against this criterion.

4. Conclusion

The species exists in extremely low numbers, a single mature individual. The geographic distribution, area of occupancy being 1m2 and extent of occurrence, 100m2, is precarious for the survival of the species. A decline in the species is likely due to the limited viability of a single specimen and vulnerability of small populations to stochastic disturbance events. The species is eligible for listing as critically endangered under criteria 2, 3 and 4.

5. Recommendation

TSSC recommends that the list referred to in section 178 of the EPBC Act be amended by transferring from the endangered category to the critically endangered category:
