Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] No / unlikely
2 Possibly extinct Is there a strong possibility that this species might be extinct in the wild? Yes
3 Phylogenetic significance The taxon’s Evolutionary Distinctiveness (ED) score, as generated by the ZSL EDGE program. (These data are not editable by Assessors). Unknown
4 Protected habitat Is a population of at least 50% of the individuals of the taxon included within a well-managed or reliably protected area or areas? No / unlikely 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, conservation translocation or supplementation Does enough well-managed and reliably protected habitat exist, either within or outside of currently protected areas that is suitable for conservation translocation, including population restoration or conservation introduction? Yes / probably 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? Yes / probably
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 likely to be reversible in time frame to prevent further decline / extinction 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 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 / probably 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 a distinctive reproductive mode, behaviour, aspect of morphology or physiology, within the Order to which it belongs (e.g. Anura, Passeriformes 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 within the Order to which it belongs (e.g. Anura, Passeriformes etc.) e.g. human medicine, climate change, environmental pollutants and conservation science? 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 bred and/or maintained in captivity? Yes, bred to F1 Private breeders have bred wild collected stock in captivity on several occasions.
16 Conservation education/ecotourism potential Is the species especially diurnal, active or colourful, or is there an interesting or unusual aspect of its ecology that make it particularly suitable to be an educational ambassador for conservation of the species in the range country, either in zoos or aquariums or within ecotourism activities? 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 If an ex situ initiative was proposed for this species, would it be supported (and approved) by the range State (either within the range State or out-of-country ex situ)? Yes / probably 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 an ex situ program, if one was recommended? Yes / probably 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.
21 In situ conservation activities Are any in situ conservation actions currently in place for this species? (Only required if a Red List Assessment has not been completed, or if new actions have been implemented since the last Red List Assessment. (Information from the Conservation Actions section of the Red List assessment should be reviewed and considered when answering this question.).
22 In situ research Is additional in situ research required to better understand the species, e.g. distribution, population trends, natural history etc.? Population trends, impacts of trade, reproduction, basic natural history
23 Action plans Does an Action Plan for the species already exist, or is one currently being developed?
24 Ex situ conservation activities Is any ex situ research or other ex situ conservation action currently in place for this species? (Information from the Conservation Actions section of the Red List assessment should be reviewed and considered when answering this question.)
25 Husbandry analog required If an ex situ rescue program is recommended for this species, would an analog species be required to develop husbandry protocols first?
26 In situ conservation activities Are additional in situ conservation actions required to help conserve this species in the wild (e.g. habitat restoration and/or protection, control of invasive species, national legislation etc.)? Improved habitat management, continued monitoring of trade
