Question #Short NameQuestion TextResponseComments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Least Concern (LC) This is a regional endemic, as far as we know is distributed only across the souther part of the high plateau from Antoetra to Ankaratra.
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? No / unlikely In Antoetra Blommersia kely might profit from the local protection of Mantella cowanii in the sites where they occur together. A part of Ankaratra is included in the list of areas that should soon receive formal protection, but the process is still ongoing and it is not known when the protected area it will be formally established. At Ankaratra deforestation is progressing at devastating rates, however this species cope well with deforested areas and antropized habitats.
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? Yes / probably In Antoetra it might be difficult, but in Ankaratra there are certainly several places where the species can be reintroduced.
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 likely to be reversible in time frame to prevent further decline / extinction Two major threats are present in both sites where this taxon occur: 1) habitat loss, progressing at high rates; 2) presence of Batrachochytrium dendrobatidis. Habitat loss can be limited by the formal establishment of the protected area in Ankaratra, for chytrid it is mandatory to investigate Bd dynamics in the wild, to assess whether this threat is reversible or not.
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 It is a small species that cope fairly well with habitat degradation inhabiting shallow water bodies/ponds. Many individuals have been found in suitable areas, thus almost certainly the population in the wild is large enough to recove rnaturally
10 Biological distinctiveness Does the taxon exhibit, for example, 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 It a rather generalized Blommersia species showing no particualr sign of strong divergence in habitat/behaviour/morphology.
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 the Order to which it belongs (e.g. Anura, Passeriformes 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? Yes Try to develop ex situ an active strategy for Blommersia reproduction is still required. Developping this know-how can potentially benefit all 9 Blommersia species (but one, Blommersia angolafa), which has a completely different reproductive strategy.
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 Yes, this is a small species, therefore it might be easier to reconstruct a suitable habitat/condition for the species ex situ. At the same time, no known typical Blommersia species are classified in any threatened category.
15 Captive breeding Has this species been successfully bred and/or maintained 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 shows diurnal and nocturnal calling activity, however, it is rather small and not particularly colourful, thus most probably it is not the ideal species for educational purposes.
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 this taxon is locally very abundant
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 The population living in Ankaratra and Antoetra have been analysed and are clearly the same species, however the two populations are currently completely separated and no gene flow is occurring between them.
