At least six species of Australian frogs have not been observed in the wild since the initial impact from the fungal chytridiomycosis and are probably extinct. Seven other frog species have been assessed as needing urgent interventions, as they have populations smaller than 1000 and headed for extinction. Management recommendations for these species include precise risk assessments, captive assurance colonies, and biosecurity.
Worldwide research on chytridiomycosis has not yet provided a solution to promote population recovery in the field, and FAUNA Research Alliance prioritise research topics with this aim. Solutions will likely differ among species. Procrastination on this issue will result in extinction.
This Project will:
- Provide precise risk assessments (PRA) for species where the situation in the wild populations is unclear and susceptibility to the fungal disease not known
- Determine husbandry requirements for species requiring captive assurance colonies
- Improve on ground management through research on assisted colonization of frogs to low risk areas, control of reservoir species, identification of sites less suitable for disease, habitat manipulation to lower disease risk and assisted selection of disease resistant frogs
