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 without correcting for suitable habitat is 1041 sq. km. It therefore can be continued to be assessed as Endangered
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? Unknown Highly likely. It is currently found in Eravikulam National Park, Anamalai Tiger Reserve, Kurunjimala Wildlife Sanctuary
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? Unknown
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 They are currently known from 13 locations. At five locations where the species is found, it is faced by potential pesticide runoff from the surrounding tea plantations (n=4 locations), firewood collection and livestock grazing (2, degraded habitat (2), tourism (2) and human-induced fire (1).
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, 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 Though the exact population estimates are not available for this species, in terms of relative abundance, it is the most abundant terrestrial species at all four sites within its distribution range where transect surveys were conducted. These surveys were undertaken during the monsoon.
10 Biological distinctiveness Does the taxon exhibit, for example, a distinctive reproductive mode, behaviour, aspect of morphology or physiology, within its Class (e.g. Amphibia, Reptilia etc.)? 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 The species cannot be easily distinguished, does not have a distinctive local name and has a low flagship potential
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 its Class (e.g. Amphibia, Reptilia 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 Since the species is found in the same habitat of the Critically Endangered Walkerana phrynoderma and is also more abundant and widespread, this species could be used in captivity to develop husbandry and breeding protocols.
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 This species can be encountered during the day but cannot be easily distinguished and is not charismatic. It may not be suitable as an educational ambassador for this group of species.
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 The proposed ex situ initiative for this species could be supported by the state of Kerala for an ex situ initiative within its physical boundaries and not outside it in another state or country.
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
