Additional Comments:
| Question # | Short Name | Question Text | Response | Comments |
| 1 | Extinction risk | Current IUCN Red List category. [Data obtained from the IUCN Red List.] | Data Deficient (DD) | |
| 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 - 50 | |
| 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? | No / unlikely | This frog is present in the states of Karnataka, Tamil Nadu and Kerala in India. In Karnataka State, it has been recorded at Bajpe and Adyar in Mangalore (Joshy et al. 2009), Agumbe Rainforest Research Station (Purushotham and Tapley 2011), Someshwara Wildlife Sanctuary (Seshadri KS, pers. comm. October 2020), Sharavathi and Kali river basins in Uttar Kannada District (Ramachandra et al. 2012), Pavuru and Konaje in Mangalore Taluk in Dakshina Kannada District (Nair and Kumar 2013), Keasruhalla, Bhadra Tiger Reserve in Chikkamagaluru District (Dinesh et al. 2013), and Kodanga in Herga Village in Udupi District (Priti et al. 2016). In Kerala State, it has been observed in the Kavvayi River Basin (Das et al. 2014). It has also been reported from Devgad in Sindhudurg district (Akshay Gawade, pers. comm. October 2020), although this requires further verification (Seshadri KS, pers. comm. October 2020). The species has also been recorded within traditionally-protected areas (Akshay Gawade, pers. comm. October 2020). It seems likely to also occur in Mudigere (Joshy et al. 2009). It is present in the protected area Western Ghats World Heritage Site (IUCN and UNEP-WCMC 2020). In Tamil Nadu State, it has been reported from Courtallam, Minnagar, Melagaram and Ilangi in the Tirunelveli District (Vasanthi et al. 2014) and Ousteri Lake in Puducherry District (Alexandar 2018) although these records have potentially been incorrectly identified (Seshadri KS, pers. comm. October 2020). It is likely to be restricted to its known range (Seshadri KS, pers. comm. October 2020). It ranges between 1 and 70 m asl (Joshy et al. 2009). |
| 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 | |
| 6 | Previous reintroductions | Have reintroduction or translocation attempts been made in the past for this species? | No | |
| 7 | 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.). | Yes / probably | It is present in a number of protected areas. |
| 8 | 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.)? | Yes / probably | Improved habitat protection is required. |
| 9 | In situ research | Is additional in situ research required to better understand the species, e.g. distribution, population trends, natural history etc.? | Yes | Further research on the effects of Bd, climate change and pesticides is required. Population monitoring is also recommended (India RLA/CNA workshop October 2020). |
| 10 | 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 | It inhabits aquatic bodies such as ponds, wetlands, ditches, paddy fields (Joshy et al. 2009). It is likely to be a fairly adaptable species (Seshadri KS, pers. comm. October 2020). Pesticide use in agricultural areas is a potential threat, either to the the tadpoles, or potentially to the prey species (Seshadri KS, pers. comm. October 2020). Road mortalities are a moderate threat (Seshadri KS, pers. comm. October 2020). Increased development for human settlements (conversion of wetlands) and urbanization is a major threat (Seshadri KS, pers. comm. October 2020). Climate change is a potential future threat as it could cause drying of the habitat (Seshadri KS, pers. comm. October 2020). Batrachochytrium dendrobatidis (Bd) has been found in other species of the genus, so chytridiomycosis may be a potential threat for this species but further research is required (Seshadri KS, pers. comm. October 2020). |
| 11 | 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 | |
| 12 | 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 | Forty-two specimens were reported during survey work conducted between 2003 and 2008 (Johsy et al. 2009). They are common where they are found (Seshadri KS, pers. comm. October 2020). |
| 13 | Action plans | Does an Action Plan for the species already exist, or is one currently being developed? | No | |
| 14 | 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 | |
| 15 | 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 | |
| 16 | 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 | |
| 17 | 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 | |
| 18 | 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.) | No / unlikely | |
| 19 | 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? | No / unlikely | |
| 20 | 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? | No | |
| 21 | Captive breeding | Has this species been successfully bred and/or maintained in captivity? | Not held in captivity to date | |
| 22 | 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? | Yes | This is a common species which is found around human settlements and would be good for education programs in the areas it is found (Seshadri KS, pers. comm. October 2020). |
| 23 | Mandate | Is there an existing conservation mandate recommending the ex situ conservation of this taxon? | No | |
| 24 | 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 | |
| 25 | 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 | |
| 26 | 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 |
