Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Least Concern (LC)
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? No
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 There certainly are many forest streams available that are suitable for this species. Unlike other frogs, in M. guttulatus like in related species (M. grandidieri) some of these might t be densely populated due to overcollecting (as the species suffers not only by habitat destruction but only harvesting as bushmeat) and so, reintroduction might at some point in time and in some locations be a real option.
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 Forest habitats with streams can be restored by reforestation, and overcollecting can be reduced by enforcing laws and environmental education.
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? Yes THe species is collected as food.
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
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 As M. grandidieri this species is exceptional among mantellid in being large-size and with a probably unique reproductive behavior.
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 The species is regularly collected as food and is well-known to locals unlike many other frog species in Madagascar.
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? Yes See comments under M. grandidieri. The reproductive behavior and life history of these species are almost completely unknown and could be elucidate in a properly managed captive colony. Husbandry will be challenging however due to the large body size of these 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? Yes The species is an analog for other species of the subgenus Mantidactylus (M. grandidieri and at least one undescribed candidate species).
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? Yes Because the species is consumed as food and is well known to locals, it could be a good flagship species for conservation and for exemplifying sustainable harvesting.
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 It should be relatively easy obtaining a permit to collect a stock for captive breeding from populations outside of protected areas.
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
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)? No The delimitation and relationships among the species in this subgenus (M. guttulatus, M. grandidieri and at least one undescribed candidate species) are in need of revision.
