5 thoughts on “Appert’s Tetraka (Xanthomixis apperti): Revise global status?”
The window for consultation is now closed and we are unable to accept any more comments until 21 February 2022. We will now analyse and interpret the new information, and we will post a preliminary decision on this species’s Red List status on this page on 21 February 2022, when discussions will re-open.
Based on available information, our preliminary proposal for the 2022.1 Red List would be to adopt the proposed classifications outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 27 February 2022, after which the recommended categorisations will be put forward to IUCN.
The final 2022.1 Red List categories will be published on the BirdLife and IUCN websites in July 2022, following further checking of information relevant to the assessments by both BirdLife and IUCN.
I support the rigorous application of RL criteria. In this case, there is no evidence that the species occurs more widely than in its core area of Zombitse-Vohibasia and Analavelona; there are one or two records from Mikea but extensive surveys in this area do not reflect a regular or significant population presence there. It certainly does not occur in Isalo.
Zombitse-Vohibasia is under continuous pressure for forest clearance for agricultural production and charcoal, and as the great majority of the species is limited to this small site (and it is patchily distributed- for instance rarely found in Vohibasia, and nowhere abundant within the site), it makes no sense at all to consider this species as anything less than VU. The analysis presented here makes this case very clearly, with only the addition of criterion B2a, which is clearly met by the species. I disagree strongly with reclassification as NT.
Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested by so many people in commenting. The window for consultation is now closed and we are unable to accept any more comments. We will analyse and interpret the new information, and we will post a final decision on this species’ Red List status on this page on 7 March 2022.
Recommended categorisation to be put forward to IUCN
Following further review and after updating the range map, the recommended categorisation for this species has been changed. Appert’s Tetraka is now recommended to be listed as Vulnerable under Criterion A2c.
Many thanks for everyone who contributed to the 2022.1 GTB Forum process. The final 2022.1 Red List categories will be published on the BirdLife and IUCN websites in July 2022, following further checking of information relevant to the assessments by both BirdLife and IUCN.
