According your first assumption, it is unlikely hard to approve Mentocrex beankaensis species as Vulnerable statute. For the occurrence site the Bemaraha tsingy and the Beanka NAP sites are both the known record of this species in the last 15 years of his discovery. However, the PA limit does not determinate the real forest habitat is under estimated (the PA limit surface does not seem equal to the forest habitat of species). Therefore, the habitat surface need more investigation. And clearly less than the actual information for Bemara NP and for Beanka NAP. The 5600km2 need to be review seriously in both PAs.
For population size 2500-9999 individuals. Available data for Beanaka forest is not enough to propose reasonable assumption. Therefore, there is an urgent need to undertake additional survey work inside the Bemaraha NP, and then compare results for real an approximate population size.
My last personal comments will concern habitat loss pressure have significant effect in species population fluctuation control of Tsingy rail. This threat off uncontrolled bush fire is very important during the dry season period almost in all western part of Madagascar according the satellite imagery fire data survey. In my opinion this is the main specific threat affecting living population of Tsingy rail rather than hunting pressure by human persecution inside of PAs. Remember Bemaraha NP and Beanka NAP are yet protected, both have reasonable protection measure and management for patrolling effort in key habitats. Pas managers need to increase conservation effort in fire control if not there is high risk of local excitation of this species is probable in near future, and consequently his conservation statute will go up rapidly. To summary, Endangered conservation statute might be the nearest to the actual situation concerning the Tsingy rail.
Further work is needed to identifying sub population of this species in the western Madagascar remote area I chance to gain additional data in population size estimate, habitat requirements to contribute in the conservation of this mystical rail about his rarity occurring in dry forest habitat in comparison into his relative occurring in rainforest habitat (M kioloides)
The recent decline in security in western and southern Madagascar has been very marked in places such as around Antsalova. In many places either bandits live in the forests such as Bemaraha where they hunt the wildlife, or conversely people who are fleeing bandits live in forests in the same way. It is dangerous to visit these forests away from areas frequented by park staff and tourists, so it will be hard to monitor changes caused by the insecurity. Based on experience from other parts of western Madagascar, the impacts of insecurity on wildlife will be significant. Beanka rail, as one of the larger and more conspicuous species in these forests, will be an easy target for hunting in these circumstances. It could easily be that the population has been substantially reduced in outlying parts of its range, to below the 2,500 threshold for EN status. For this reason, a precautionary approach would be to give the species VU by adding criterion Bbiv and C, C1.
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. We will analyse and interpret the new information and post a preliminary decision on this species’s Red List status on this page in early July.
Thank you once again,
BirdLife Red List Team
Based on available information, our preliminary proposal for the 2021 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 in mid-July, after which the recommended categorisations will be put forward to IUCN.
The final 2021 Red List categories will be published on the BirdLife and IUCN websites in December 2021, following further checking of information relevant to the assessments by both BirdLife and IUCN.
Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. Tsingy Wood-rail is recommended to be listed as Vulnerable under Criterion B1ab(iii).
Many thanks for everyone who contributed to the 2021 GTB Forum process. The final 2021 Red List categories will be published on the BirdLife and IUCN websites in December 2021, following further checking of information relevant to the assessments by both BirdLife and IUCN.
