Additional Comments:
If the species is found, population size should be estimated. If possible, research should demonstrate that there are enough individuals in nature to start an ex situ program. At first (as part of a program), studies with analogous species could inform management protocols before working with this species.
| 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? | Yes / probably | This species is just known from its type locality in Serra de Macaé (Nova Friburgo, RJ), last seen in 1909. Surveys in 2013 and 2017 (Santos et al. 2020, Systematic Revision of the Rare Bromeligenous Genus Crossodactylodes Cochran 1938 (Anura: Leptodactylidae: Paratelmatobiinae), Herpetological Monographs, 34(1):1-38) did not record individuals in this area. |
| 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 well-managed or reliably protected area or areas? | No / unlikely | Serra de Macaé is not a protected area. Distribution area was estimated in 4 Km2. |
| 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? | No / unlikely | Serra de Macaé has extensive remnants of well-preserved forest, with available bromeliad habitat for the species. |
| 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.). | No / unlikely | |
| 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 | Develop a species management and recovery plan. If the species is rediscovered, implement habitat protection and promote the creation of a protected area. |
| 9 | In situ research | Is additional in situ research required to better understand the species, e.g. distribution, population trends, natural history etc.? | Yes | Research is needed on species distribution, therefore modelling potential habitats and occurrence is a priority. Type locality for this species is not precise (Santos et al. 2020) and additional surveys outside its known type locality are needed to search individuals and/or new populations through active search (visual and acoustic), environmental DNA, and/or automated acoustic recorder. It is also necessary to understand the causes for the species disappearance. |
| 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 unknown | Habitat degradation and bromeliad collection are potential threats for this species. |
| 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? | No / unlikely | |
| 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 | Laboratory controlled experiments with related species to determine the degree of tolerance of changes in habitat, in particular, related to the structure of bromeliad and different temperatures. Similar experiment was conducted for Scinax perpusillus (Greenspan et al. 2020 Nature Climate Change 10: 1) |
| 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? | Yes / probably | Crossodactylodes izecksohni. Note: All species of Crossodactylodes are threatened, but populations of C. izecksohni is in a slightly better condition, however this should be considered with caution as its situation is also complicated. |
| 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? | No | |
| 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? | No / unlikely | |
| 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 |
