Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Endangered (EN) Probably restricted to very small range. S. staffordi occurs in an area flagged as a protected site. Nevertheless, forest destruction in this area is ongoing and has even intensified in the last years (D’Cruze et al. 2007, Köhler et al. 2010). On the other hand, because of their specialization to karstic habitat and partly caves, this largebodied Stumpffia are probably less affected by deforestation than other Malagasy frog species. However, species are prone to the effects of human activities or stochastic events, and are thus capable of becoming Critically Endangered or even Extinct in a very short time period. Because of severe and ongoing habitat alteration, we propose the status "Endangered" KÖHLER, J., M. VENCES, N. D'CRUZE & F. GLAW (2010): Giant dwarfs: discovery of a radiation of large-bodied 'stump-toed frogs' from karstic cave environments of northern Madagascar. Journal of Zoology 282 (1): 21–38.
2 Possibly extinct Is there a strong possibility that this species might be extinct in the wild? No Nothing known about poputation status. Only 2 specimens collected. Habitat rather restricted (caves).
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 - 50
4 Protected habitat Is a population of at least 50% of the individuals of the taxon included within a reliably protected area or areas? No The area of occurrence is flagged protected area, but alteration of the natural habitat is ongoing and has been intensified in last years.
5 Habitat for reintroduction Does enough suitable habitat exist, either within or outside of currently protected areas that is suitable for reintroduction or translocation? Unknown The question is whether this species does occur outside of caves. If not, the habitat is really restricted to few caves of Montagne des Francais.
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 See above. Massive alteration of habitat going on.
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 as far known 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 Nothing known on population status.
10 Biological distinctiveness Does the taxon exhibit, for example, a distinctive reproductive mode, behaviour, aspect of morphology or physiology, within the Class Amphibia? Aspect of biology shared with < 6 other species Cave-dwelling large-bodied species of Stumpffia. Reverse evolution of body size from small ancestors. Probably interesting reproductive biology.
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 Probably not. Saving habitat is most important.
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 Possibly yes, as there are more of these related species known from karstic caves.
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 Not really, although it might be interesting to demonstrate this species as part of a particular Madagascan cave fauna.
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 Population status not known.
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 Identified by integrative taxonomic approach. Relationships almost clear. Forms a calde with other large-bodied species from karstic environments in the north of Madagascar. KÖHLER, J., M. VENCES, N. D'CRUZE & F. GLAW (2010): Giant dwarfs: discovery of a radiation of large-bodied 'stump-toed frogs' from karstic cave environments of northern Madagascar. Journal of Zoology 282 (1): 21–38.
