Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Critically Endangered (CR) Very small distribution (~1km2) at the highest elevations on Mahe which could be considered one location. Population trends are unknown but it can be projected that due to only occurring at the highest elevations that with climate change suitable habitat will be rapidly reduced.
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 reliably protected area or areas? Yes / probably The species only occurs in the Morne Seychellois National Park, an area that is fully protected.
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? No / unlikely
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 cannot / will not be reversed in time to prevent further decline / extinction Climate change is seemingly the biggest threat facing H. montanus. The species only occurs at the highest elevations and has no additional capacity to move higher up the mountain with increasing levels of climate change.
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? No / unlikely
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 We know very little about the species biology.
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? (e.g. human medicine, climate change, environmental pollutants and conservation science), within its Class (e.g. Amphibia, Reptilia etc.)? Research dependent upon < 6 species (incl. this taxon) As a taxon restricted to high-elevation, mist-forest habitat, research on this species will provide information important for assessing climate-related risks to some of the region's other fauna and flora, as well as human well-being.
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? No
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 Could educate people on the importance and threat of climate change to other fauna and flora in the Seychelles
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
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
