Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Critically Endangered (CR) Its only known locality, the Forêt d'Ambre Special Reserve, is legally protected but under heavy pressure, resulting in logging and agriculture within the reserve area (D'Cruze et al. 2008). For these reasons (extent of occurrence is less than 5,000 km2,all individuals are in only one location, and there is heavy decline in the extent and quality of its forest habitat), B. baetkei should be considered as "Endangered" according to IUCN criteria
2 Possibly extinct Is there a strong possibility that this species might be extinct in the wild? No
3 Phylogenetic significance The taxon’s Evolutionary Distinctiveness (ED) score, as generated by the ZSL EDGE program. (These data are added by AArk staff, and are not editable by Assessors). ED value < 20
4 Protected habitat Is a population of at least 50% of the individuals of the taxon included within a reliably protected area or areas? Yes Forêt d'Ambre Special Reserve, is legally protected but under heavy pressure, resulting in logging and agriculture within the reserve area (D'Cruze et al. 2008). D'CRUZE, N., J. KÖHLER, M. FRANZEN & F. GLAW (2008): A conservation assessment of the amphibians and reptiles of the Forêt d'Ambre Special Reserve, north Madagascar. Madagascar Conservation & Development 3 (1): 44–54.
5 Habitat for reintroduction Does enough suitable habitat exist, either within or outside of currently protected areas that is suitable for reintroduction or translocation? Yes Currently yes, but the habitat is continously atered.
6 Previous reintroductions Have reintroduction or translocation attempts been made in the past for this species? No
7 Threat mitigation Are the threats facing the taxon, including any new and emerging threats not considered in the IUCN Red List, potentially reversible? Threats cannot/will not be reversed in time As far known, tiny range, microendemic. Heavy and ongoing degradation in Foret d'Ambre Reserve. No efficient protection of habitat of the species.
8 Over-collection from the wild Is the taxon suffering from unsustainable collection within its natural range, either for food, for the pet trade or for any other reason, which threatens the species’ continued persistence in the wild? No To current knowledge not in trade.
9 Population recovery Is the known population of this species in the wild large enough to recover naturally, without ex situ intervention if threats are mitigated? Unknown Unknown, but likely the existing population can recover naturally under certain preconditions.
10 Biological distinctiveness Does the taxon exhibit, for example, a distinctive reproductive mode, behaviour, aspect of morphology or physiology, within the Class Amphibia? No aspect of biology known to be exceptional
11 Cultural/socio-economic importance Does the taxon have a special human cultural value (e.g. as a national or regional symbol, in a historic context, featuring in traditional stories) or economic value (e.g. food, traditional medicine, tourism) within its natural range or in a wider global context? No
12 Scientific importance Is the species vital to current or planned research other than species-specific ecology/biology/conservation? (e.g. human medicine, climate change, environmental pollutants and conservation science), within the Class Amphibia? No research dependent on this species
13 Ex situ research Does conserving this species (or closely related species) in situ depend upon research that can be most easily carried out ex situ? No Very little is known on the biology of this species. Only two male specimens known. But conservation of habitat would first be the correct measure to conserve this species.
14 Husbandry analog Do the biological and ecological attributes of this species make it suitable for developing husbandry regimes for more threatened related species? i.e. could this species be used in captivity to help to develop husbandry and breeding protocols which could be used for a similar, but more endangered species at a later stage? No
15 Captive breeding Has this species been successfully maintained and bred in captivity? Not held in captivity to date
16 Educational potential Is the species especially diurnal/active/colourful and therefore suited to be an educational ambassador for conservation of this group of species? No Nocturnal. One of the many green treefrogs of Madagascar.
17 Mandate Is there an existing conservation mandate recommending the ex situ conservation of this taxon? No
18 Range State approval Would a proposed ex situ initiative for this species be supported (and approved) by the range State (either within the range State or out-of-country ex situ)? No
19 Founder specimens Are sufficient animals of the taxon available or potentially available (from wild or captive sources) to initiate the specified ex situ program? Unknown
20 Taxonomic status Has a complete taxonomic analysis of the species in the wild been carried out, to fully understand the functional unit you wish to conserve (i.e. have species limits been determined)? Yes Species identification by integrative taxonomic approach. KÖHLER, J., F. GLAW & M. VENCES (2008): Two additional treefrogs of the Boophis ulftunni species group (Anura: Mantellidae) discovered in rainforests of northern and south-eastern Madagascar. Zootaxa 1814: 37–48.
