Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Critically Endangered (CR) The taxon was only described in 2004 and there is still at lot to be known about its preference of habitat, interactions with other species, and husbandry. Taxon is locally very abundant but we believe its range is limited to less than 100 square Km. A lot of its range overlaps with private tea plantation properties.
2 Possibly extinct Is there a strong possibility that this species might be extinct in the wild? No The species is not extinct in the wild yet. It has a narrow range of distribution that makes it a potential candidate for extinction.
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 are aware that this species is found in the lower elevation of the Eravikulam National Park. However, we don't have estimates on what proportion of the entire population is present in the park.
5 Habitat for reintroduction Does enough suitable habitat exist, either within or outside of currently protected areas that is suitable for reintroduction or translocation? Unknown Unknown at this time and unlikely to be needed at this time as is locally abundant.
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 unknown While there are no imminent direct threats to the species, we have no studies on the possible impacts of fragmentation, management by the tea industry, or increasing temperatures associated with climate change on this taxon.
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 This taxon is not encountered in the pet trade industry, nor is it known to be a player in the food industry. However, if it becomes of interest for collections then it will be in danger of extinction as the range of distribution is extremely narrow.
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 Unfortunately, we don't have this information. We do know that in certain parts of its distribution range it is extremely abundant.
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 These are direct developing bush frogs found in the Western Ghats. While they don't have any known unique characteristics, there is little to no published data available on the taxon, other than its description. Therefore, it is premature to assume that the species is 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? No These are small grey frogs that are not morphologically distinct but appear to be very delicate because of their size. The locals in the area don't seem to concern themselves with this species.
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 To the best of our knowledge there are no projects directly studying anything species specific with respect to this taxon. However, there is a need to look at the possibility that the species is not selected for the same because it is not an attractive animal.
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 There is a lot of potential for understanding and learning about the husbandry techniques of species from the same genus that could be obtained from studying the taxon Ex-situ. While the taxon is Critically Endangered itself, there are other species from the Genus Raorchestes that are known to be less abundant and research with R. griet can be used develop better methods and techniques for the husbandry of other species from the Genus.
15 Captive breeding Has this species been successfully maintained and bred in captivity? Not held in captivity to date The authors have no record of the species being held in captivity.
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 While it is not the most attractive amphibian in its location, it is locally abundant and easy to find because of its loud call. It can serve as an example for species that are not charismatic but play an important role in ecosystem interactions.
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 There is a high chance that an ex-situ initiative for the species would be supported as long as the initiative is planned within the range state.
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 This species is easy to identify in the field by it call and by it morphological appearances. The morphological variations in the individuals are identifiable making it a viable candidate for ex-situ breeding programs from a taxonomic perspective.
