Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Endangered (EN) The Extent of occurrence of the species is 171 sq. km. Therefore, based on the IUCN Redlist criteria it can be assessed under Endangered B1ab(iii)
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).
4 Protected habitat Is a population of at least 50% of the individuals of the taxon included within a reliably protected area or areas? Unknown We don't have this information.
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 Its a species found above 1200 meters in Evergreen and Shola Forests as well as tea/cardamom plantations in Western Ghats. This species has been encountered along streams in large numbers in tea plantations. These streams were observed several years in a row and the species appears stable in this plantation landscape.
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 The species faces the regular pressures that flora and fauna in the Western Ghat face, like habitat loss, and fragmentation. Riparian habitat along streams at tea plantations are regularly maintained, which affects its distribution temporarily as they are displaced to other habitats during such activities. The effect of such maintenance on species abundance or reproduction is however not known.
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? Unknown While we have seen this species across the Munnar landscape we do not have sufficient data to say that the species can recover naturally without intervention.
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
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 We are unaware of anything in this regard yet.
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
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 We need more information on its breeding Biology in the wild before in situ plans can be formulated. This information on husbandry can be generated with a captive stock.
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 can be an analog for species from the same genus. For Ex., G. variabilis, which is not observed to be as common, as well as, G. magnus a recently described species which has not yet been assessed.
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? Yes They are beautiful frogs with a star patterned iris. They are large and easy to find along streams at night in Munnar, Kerala and Kodaikanal, Tamil Nadu. They have a characteristics call that sounds like that of a bird that can be easily distinguished from other frog calls in the same habitat. The species is nocturnal, and hence it is unlikely that these features can be observed during the day in ex-situ conditions.
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 Range state approval would be likely as long as the ex-situ work is planned within the state boundaries.
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)? Yes
