Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Endangered (EN)
2 Possibly extinct Is there a strong possibility that this species might be extinct in the wild? No / unlikely
3 Phylogenetic significance The taxon’s Evolutionary Distinctiveness (ED) score, as generated by the ZSL EDGE program. (These data 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 / unlikely Populations exist in Torotorofotsy Ramsar site, Ambohitantely Special Reserve, and Zahamena National Park, but known localities occur in the CAZ (Zahamena-Ankeniheny Corridor) which is not reliably protected and many sections open for regulated use.
5 Habitat for reintroduction Does enough suitable habitat exist, either within or outside of currently protected areas that is suitable for potential reintroduction or translocation? Yes / probably CAZ, Torotorofotsy, Zahamena, etc. If similar to M. aurantiaca, likely habitat would need to be restored/created within native range.
6 Previous reintroductions Have reintroduction or translocation attempts been made in the past for this species? Yes, but outcome is unknown Translocations from breeding ponds on the footprint of the Ambatovy nickel and cobalt mine to created sites in the Conservation Zone around the mine have taken place since 2013 but it is unknown if they are successful or not. Continued long-term monitoring and additional translocations will take place over coming years.
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 destruction is the main threat to the species and potentially could be reversed in time to prevent extinction, however, local populations likely may go extinct in meantime while threats are being addressed. Occurs within several protected areas, though the species survival depends on their management.
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 / probably CITES II. Has not been collected since 2008 since CITES quota was set to 0, but historically collected by the thousands for the international pet trade and likely in unsustainable numbers depending on targeted populations, though other surveys indicate that numbers possibly were sustainable. See Rabemananjara, F., et al. 2008. Malagasy poison frogs in the pet trade: a survey of levels of exploitation of species in the genus Mantella. Amphibian & Reptile Conservation 5(1): 3-16
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
10 Biological distinctiveness Does the taxon exhibit, for example, 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 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 - pet trade.
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 Order to which it belongs (e.g. Anura, Passeriformes 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? Yes Population ecology and dynamics for sustainable trade; habitat use and preference for translocations.
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 Husbandry of closely related species already understood.
15 Captive breeding Has this species been successfully bred and/or maintained in captivity? Yes, bred to F2 Successfully bred to F2 generation outside of range country by private breeders and within cosmopolitan zoo collections. Possibly bred in Madagascar by animal exporters.
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 Diurnal, colorful, easily observed and useful for raising awareness of other threatened species in the genus other than M. aurantiaca.
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 / 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 the specified ex situ program? Yes / probably
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 Yes, but relationship to M. milotympanum at certain intermediate populations unclear. It is possible this species is a color variant of M. crocea.
