Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Endangered (EN) The Tennessee Wildlife Resources Agency (1994) has listed G. palleucus as Threatened; because G. gulolineatus was recognized as a subspecies of Tennessee cave salamanders at the time of listing and only occurs in Tennessee, the arguments for listing G. gulolineatus are equally valid.
2 Possibly extinct Is there a strong possibility that this species might be extinct in the wild? No / unlikely They were shown to be in decline even in the early 1990's (Caldwell and Copeland 1992). However, more recent work has shown some of those populations have more substantial populations (Miller and Niemiller 2007).
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? No / unlikely The species exists in caves which are impacted by disturbance to above ground habitat. To my knowledge (VRF) the majority of populations are still susceptible to disturbance, especially urban development.
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 are reversible in time frame All populations are tied to the water quality and therefore above ground disturbances have the potential to impact populations. Focusing on maintaining water quality will be importance for the maintenance of this species.
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 Miller and Neimiller (2007) found several robust populations.
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
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? No
15 Captive breeding Has this species been successfully maintained and bred in captivity? Maintained but no successful breeding
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
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 See Miller and Neimiller 2007
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 Several phylogenetic and systematic studies including Gyrinophilus gulolineatus (e.g., Neimiller et al. 2008, Brandon et al. 1986, Collins and Taggart 2002, and Crother et al. 2000) have been completed.
