Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Least Concern (LC) This is a relatively wide distributed species in the north west of Madagascar, it inhabits different habitats (from rainforest to swamp areas and it might be locally very abundant.
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? Yes It occurs in many protected areas, for example: Lokobe, Ankarafantsika, Sahamalaza, Manongarivo
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 This species show a high tolerance to a wide range of habitat. It is widely distributed across different habitat except the high plateau and the arid southwest, always under 1600 m svl.
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 being very adaptable this is not seriously threatened. However, it is likely to be a complex of several cryptic species, in this case some of the species within the complex might prove to be threatened, especially by pollution of streams, and extreme opening up of the 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? No
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 But a detailed taxonomic study is needed to identify the different Units for Conservation
10 Biological distinctiveness Does the taxon exhibit, for example, a distinctive reproductive mode, behaviour, aspect of morphology or physiology, within the Class to which the species belongs (Amphibia, Mammalia etc.)? No aspect of biology known to be exceptional Eggs are deposited in teh leaf litter or on rocks next to water and tadpoles are flushed into slow moving stream where they develop into froglet.
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 to which the species belongs (Amphibia, Mammalia etc.)? 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
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 This species is abundant, common and wide distributed, it can definitively be an husbandry analog to develop husbandry regimes for different species of the subgenus Brygoomantis
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 Species not colorful and during the day has generally secretive habits
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
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 This is a locally abundant species wish is also widely distributed. Sufficient animals available to initiate an ex-situ program are available, pending a full taxonomic revision aiming at identifying the cryptic species hidden within this taxon name.
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 This is an unresolved species complex and an accurate taxonomic revision is required to resolve their identity and distribution
