Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Vulnerable (VU)
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? Unknown Population size unknown, but occurs at Andasibe in Andasibe-Mantadia National Park, Analamazaotra Forest Station and probably north in the CAZ, which are to different degrees protected areas.
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 Forests around Andasibe - Andasibe-Mantadia National Park, Analamazaotra Forest Station, CAZ, etc.
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 are reversible in time frame Habitat loss is the largest threat, but occurs in protected areas around Andasibe and if these areas are well-managed then this threat is reversible.
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? Unknown Collected for the international pet trade but not known whether in sustainable numbers or not.
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? Yes Abundant during certain times of the year around Andasibe (pers. obs.) including both in forest and nearby villages. Population size not known but presumably large enough to recover naturally without ex situ intervention.
10 Biological distinctiveness Does the taxon exhibit, for example, a distinctive reproductive mode, behaviour, aspect of morphology or physiology, within the Class to which the species belongs (Amphibia, Mammalia etc.)? No aspect of biology known to be exceptional Not known to be biologically distinct.
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? Yes Socio-economic importance - collected for pet trade but also often one of the few frog species local guides in Andasibe reliably identify and make an effort to show to tourists.
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 to which the species belongs (Amphibia, Mammalia etc.)? No research dependent on this species Not known to be scientifically important.
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
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? Yes Possible Scaphiophryne gottlebei analogue since both are in the same genus and explosive breeders, though S. gottlebei inhabits a different environment and perhaps there are better analog species.
15 Captive breeding Has this species been successfully maintained and bred in captivity? Yes, bred to F1 Private breeders have bred wild collected stock in captivity on several occasions.
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 Does not display particularly well in captivity.
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)? Yes The Sahonagasy Action Plan is ratified by the Malagasy government and states support for ex situ initiatives for all amphibian species in Madagascar.
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? Yes Abundant around Andasibe during certain times of year. Sufficient founders available.
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 See Vences, M., Raxworthy, C.J., Nussbaum, R.A. and Glaw, F. 2003. A revision of the Scaphiophryne marmorata complex of marbled toads from Madagascar, including the description of a new species. Herpetological Journal: 69-79.
