|Scientific research and community engagement were conducted in Tasmania from November 2007 to November 2009 under the umbrella of the Platypus Partnership Program. Research efforts focused on addressing fundamental gaps in the understanding of mucormycosis disease, including the contemporary distribution and prevalence of the disease, its impact on populations, and the mechanisms of disease transmission, and involved researchers within the Department of Primary Industries and Water, the Universities of Tasmania, Sydney and Adelaide, and the Centre for Environmental Stress and Adaptation Research. Community engagement initiatives were aimed at raising awareness of platypus conservation efforts and encouraging public reporting of healthy and apparently ulcerated platypus. |
An extensive series of field trapping surveys was undertaken to assess the health and disease status of platypus populations in catchments across Tasmania.
Disease prevalence (the infected proportion of the population) appears to have declined since the mid- to late-1990s. Platypus populations that were affected by the disease in the mid- to late-1990s still persist, although it is unclear whether their abundance has declined or not. Ulcerated platypuses captured in this study were from the Meander, Brumbys-Lake, South Esk and North Esk catchments.

Research results from the Platypus Partnership Program and conservation options for the Tasmanian platypus were discussed in a forum at the project's conclusion. The abstracts and workshop booklet from that forum are available and provide a summary of the project's research findings.

The Platypus Management Plan outlines key short and long term management actions, and monitoring required to ensure healthy individuals and populations persist throughout the State.
The management actions address the most significant threats to Tasmanian platypus populations. They include measures to reduce road-kill, reduce predation, reduce rubbish and pollution in waterways, reduce the introduction and impact of alien species, and manage disease within populations. In addition management actions outline responsible land management and sustainable land use practices, and responsible fisheries and angling. To monitor the health and status of platypus populations, the public are encouraged to report sightings of healthy and sick platypuses (link here to “Report Platypus Sightings”). Repeat platypus trapping surveys will also be undertaken.
The success of management actions depends on the response of community members and government alike. We all have a role to play to maintain healthy waterways and the persistence of healthy platypus populations into the future.
