Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Critically Endangered (CR)
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 Occurs in CAZ (Ankeniheny-Zahamena Corridor) which receives some degree of legal protection but in reality the tiny area where M. milotympanum occurs is not reliably protected.
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 CAZ north of Mantadia National Park, though area is not well-managed or protected. Possibly also in the north of Mantadia National Park.
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 Habitat destruction is the main threat to Mantella milotympanum. Recent site visits (2014, unpublished, pers. obs.) have found the species in forest already cleared and being prepared for slash and burn agriculture. Existing forest along Ivohitra river where species is known is fragmented and interspersed with degraded habitat.
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 CITES II quota 0 as of 2009, but prior to this year exported in large numbers for pet trade and mainly collected at one highly targeted site (Sahamarolambo). See Razafimahatratra, B. et al. 2009. The status of Mantella milotympanum in the Ankeniheny-Zahamena Corridor, eastern Madagascar. Herpetology Notes 2: 207-213 and 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 Population size in the wild unknown, but known from at least two dozen localities, most along the Ivohitra river and presumably here the population is large enough to recover naturally without ex situ intervention if threats are addressed.
10 Biological distinctiveness Does the taxon exhibit, for example, a distinctive reproductive mode, behaviour, aspect of morphology or physiology, within the Class Amphibia? 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 - pet trade. Sign promoting tourism featuring the species at the intermediate M. crocea / M. milotympanum populationat Ambohidray.
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 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
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 Captive husbandry for Mantella species well understood.
15 Captive breeding Has this species been successfully maintained and bred in captivity? Yes, bred to F2 Bred to F2 generation outside of range country in private collections and zoological institutions. Genetics of captive populations not managed, maintained informally as part of cosmopolitan collections.
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 Color, diurnal, charismatic and well-suited for environmental outreach and awareness activities.
17 Mandate Is there an existing conservation mandate recommending the ex situ conservation of this taxon? Yes
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
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 Unclear whether M. milotympanum is a color variant of M. crocea. The conservation unit of wild populations at different localities expressing different phenotypes not known.
