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? Yes
3 Phylogenetic significance The taxon’s Evolutionary Distinctiveness (ED) score, as generated by the ZSL EDGE program. (These data are not editable by Assessors). Unknown
4 Protected habitat Is a population of at least 50% of the individuals of the taxon included within a well-managed or reliably protected area or areas? Yes / probably It occurs in many protected areas, for example: Lokobe, Ankarafantsika, Sahamalaza, Manongarivo
5 Habitat for reintroduction, conservation translocation or supplementation Does enough well-managed and reliably protected habitat exist, either within or outside of currently protected areas that is suitable for conservation translocation, including population restoration or conservation introduction? Yes / probably 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? Yes / probably
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 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 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 / unlikely
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 But a detailed taxonomic study is needed to identify the different Units for Conservation
10 Biological distinctiveness Does the taxon exhibit 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 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 within the Order to which it belongs (e.g. Anura, Passeriformes etc.) e.g. human medicine, climate change, environmental pollutants and conservation science? 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 bred and/or maintained in captivity? Not held in captivity to date
16 Conservation education/ecotourism potential Is the species especially diurnal, active or colourful, or is there an interesting or unusual aspect of its ecology that make it particularly suitable to be an educational ambassador for conservation of the species in the range country, either in zoos or aquariums or within ecotourism activities? 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 If an ex situ initiative was proposed for this species, would it be supported (and approved) by the range State (either within the range State or out-of-country ex situ)? Yes / probably
19 Founder specimens Are sufficient animals of the taxon available or potentially available (from wild or captive sources) to initiate an ex situ program, if one was recommended? Yes / probably 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 Research into species validity needs to be prioritised. This is an unresolved species complex and an accurate taxonomic revision is required to resolve their identity and distribution
21 In situ conservation activities Are any in situ conservation actions currently in place for this species? (Only required if a Red List Assessment has not been completed, or if new actions have been implemented since the last Red List Assessment. (Information from the Conservation Actions section of the Red List assessment should be reviewed and considered when answering this question.).
22 In situ research Is additional in situ research required to better understand the species, e.g. distribution, population trends, natural history etc.? Population size/trends
23 Action plans Does an Action Plan for the species already exist, or is one currently being developed? Although it is included in the amphibian conservation action plan for Sahamalaza by Penny et al (2016), but this is only one of many localities where the species occurs.
24 Ex situ conservation activities Is any ex situ research or other ex situ conservation action currently in place for this species? (Information from the Conservation Actions section of the Red List assessment should be reviewed and considered when answering this question.)
25 Husbandry analog required If an ex situ rescue program is recommended for this species, would an analog species be required to develop husbandry protocols first?
26 In situ conservation activities Are additional in situ conservation actions required to help conserve this species in the wild (e.g. habitat restoration and/or protection, control of invasive species, national legislation etc.)? Improved protection of protected areas where species occurs
