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 / 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 Found in a number of protected areas (Ranomafana NP, Mantadia NP, Andringtra NP, CAZ, Vohimana, Ivohibe SR, Midongy du Sud, etc.), however, some of these sites are not reliably protected and the forests and forest fragments between protected sites also harbor populations of M. baroni, probably more than 50%.
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 Much of the central eastern rain forest corridor. Protected forests at Ranomafana and Mantadia National Parks.
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 likely to be reversible in time frame to prevent further decline / extinction Habitat loss is the main threat and can be addressed through improved management in time to prevent extinction. Effects of trade can be addressed through further research and adjusting export quotas accordingly.
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? Unknown CITES II. Export quotas between 3,000 and 10,000 individuals per year between 2005 and 2015. Some research suggests trade is sustainable, though more thorough studies are needed. Probably local populations heavily targeted by collectors are at risk.
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 Population large enough to be stable if threats are mitigated.
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 Economic value through trade and tourism. Culturally important to some extent in communities around Ranomafana and Mantadia National Parks where the species can be seen displayed in pictures or handicrafts as an icon of surrounding forests.
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 Reproductive biology, such as fecundity and age to sexual maturity, would be best studied in captivity and, similar to other heavily traded Mantella spp., could be used to better model effects of 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? Yes Possible analog for Mantella cowanii
15 Captive breeding Has this species been successfully bred and/or maintained in captivity? Yes, bred to F2 Widely held in private collections and zoological institutions, and occasionally bred. Captive population sourced through pet trade from unknown localities and not properly managed.
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 Well suited for display - diurnal, colorful - and could be used to raise awareness of amphibians and amphibian conservation in Madagascar. On display at national zoo Parc Tsimbazaza as well as some private zoological parks in Madagascar, though individuals are sourced from the wild and not maintained well.
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 Sahonagasy Action Plan
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 Phenotypic differences between populations need to be considered and may warrant separate conservation units. See Rabemanananjara et al. 2007. Evidence for recent gene flow between north-eastern and south-eastern Madagascar poison frogs from a phylogeography of the Mantella cowani group. Frontiers in Zoology 4: 1-10. Mantella baroni, M. cowani, and M. nigricans all closely related.
