The Otway Bioscan incorporated a range On December 19, 2015, lightning strikes ignited two of opportunities for community participation and bushfires in the Barwon Otway Region, one near engagement. These events allowed for knowledge Delaneys Road and the other near Jamieson Track. transfer and exploration of the natural world at a In the early stages, these fires, which became known local level, while at the same time building and as the Wye River–Jamieson Track fire, were largely strengthening community relationships, particularly in controlled and contained but the combination of the Wye River and Separation Creek areas. strong winds, heat, and dry conditions resulted in the fire jumping containment lines on December 25 and by Boxing Day 98 houses in Wye River and 18 in Objectives Separation Creek had been destroyed. The major objectives of the Otway Bioscan were: The Otway Ranges are characterised by steep • To improve ecosystem knowledge and terrain and complex gully systems that are difficult understanding of biodiversity values of the GONP. to access and thus difficult to defend from fire. The Wye River–Jamieson Track fire lasted for 34 days and • To encourage community involvement. approximately 2500 hectares of land was burned, • To provide opportunities to establish citizen including areas within the Great Otway National Park. science initiatives.

This may be due, in part, to the loss of tourist infrastructure (e.g. holiday rentals) or the perceived loss of nature and natural beauty. Project Benefits As part of the Wye River Recovery Project, a The Otway Bioscan has the potential to benefit collaboration between Museums Victoria (MV) and Parks Victoria, Museums Victoria, local communities, Parks Victoria (PV) was established and the Otway local businesses, the scientific community and the Bioscan project was born. In spite of the devastating environment. Some specific benefits are listed below. effects of the 2015/16 fires, the Great Otway National Economic: This project enhanced the knowledge of Park (GONP) remains an area of important biological, biodiversity assets in the GONP. This knowledge has the geological and cultural value and the main aim of the potential to assist PV in relation to the allocation and Otway Bioscan was to further investigate, discover and targeting of PV resources. showcase (to locals and tourists) the national park’s rich and resilient environment. Social: This project engaged local communities and provided access to expert advice and skills (MV and From September 2018 to March 2019 MV and PV PV). This project will help to increase community staff, scientists and volunteers carried out a series of understanding of the environment, which may, in turn, biological surveys within the GONP. The groups covered assist in creating a shared vision for the management of included birds, freshwater fish, insects (i.e. aquatic the GONP. species, moss bugs and moths), small mammals, reptiles and amphibians. In addition, geology and Environmental: Through an increased understanding palaeontology pilot surveys were conducted in the of the environment, PV will be able to better inform western part of the park. park planning and management, with an emphasis on the long-term preservation of biota. The combined expertise of MV and PV staff resulted in the collection of important data that adds to our knowledge and understanding of the biological Scope diversity within the park, which in turn contributes The scope of the project focused on the expertise of to conservation management. In addition, the rich Museums Victoria’s staff, with agreement between PV imagery, data and knowledge captured during and MV. The details of the investigations undertaken these surveys will be a shared resource that PV can during this project can be found in this report. 6 Otway Bioscan Great Otway National Park July 2018–June 2019 Deliverables Ken Walker (bees and moss bugs) Kevin Rowe (small mammals) • Species lists for the areas surveyed Kylea Clarke (reptiles and amphibians) • Distribution of biodiversity data and images, via Maggie Haines (reptiles and amphibians) MV’s Collections On-line website and the Atlas of Maik Fiedel (reptiles and amphibians) Living Australia, with attribution to ‘The Museums Victoria–Parks Victoria Great Otway National Mark Nikolic (birds and moths) Park Bioscan’.
