Banding and radio-tracking juvenile powerful owls in Melbourne, Victoria : trials and tribulations

The Powerful Owl (Ninox strenua) is Australia's largest owl. Considering their large size they are a very cryptic species, with limited sexual dimorphism, silent fight and a highly camouflaged presence amongst secluded canopy vegetation. These features enable Powerful Owl presence to often go unnoticed and even for the trained eye, extremely difficult to study. Our research has focused on monitoring the behaviour of individual Powerful Owls in urban Melbourne, Australia.
The leg banding of Powerful Owls is a somewhat contentious issue in Australia and here we report on the suitability of different types of legs bands placed on the tarsus of juvenile Powerful Owls. There has been some debate over the band size that should be used and the consequent effects bands may pose for the owls as they mature. We also investigate the usefulness of bands as a technique to identify Powerful Owls once they have dispersed from the natal territory.
Radio-tracking juvenile Powerful Owls was also undertaken during this study, primarily to determine individual behaviour from post fledging until dispersal. This is the first study in Australia to attempt radio-tracking juvenile Powerful Owls and the results from this research highlight behavioural characteristics, mortality rates post fledging and dispersal movements for the twelve months post fledging.
Overall we found that aluminium legs bands are a useful tool for individual identification of juvenile Powerful Owls post fledgling, however, their presence is somewhat difficult to determine on mature adults as the tarsus feathers tend to cover the band and make vision from the ground difficult. Aluminium leg bands are also useful as an identification tool for deceased birds. Leather leg bands are more suitable than aluminium bands when attaching radio-transmitters as these provide more flexibility and can be removed by the owl if they become irritating.
Radio-tracking juvenile Powerful Owls provided invaluable information relating to juvenile behaviour and movements, showing that juveniles actually remain in territories adjacent to their natal territory for the twelve months post fledging. This information is vital for the successful conservation of this species, particularly in relation to habitat conservation and home-range modelling.

Distribution and abundance of the white-faced storm petrel (Pelagodroma marina) in Victoria

Habitat loss and modification is a major factor driving reductions of seabird populations. The white-faced storm petrel (Pelagodroma marina) is restricted to three breeding colonies within Victoria: Mud Islands and South Channel Fort in Port Phillip Bay, and Tullaberga Island off Mallacoota. The numbers of storm petrels breeding on Mud Islands and South Channel Fort have declined considerably, possibly a result of the significant vegetation changes, together with increases in local populations of other species of birds, most notably, silver gulls (Larus novaehollandiae). On Mud Islands the breeding area available to the storm petrels appears to be limited by the recent arrival of the Australian white ibis (Threskoirnis molucca), and straw-necked ibis (T. spinicollis) which now breed on the islands in large numbers (approximately 15,000 pairs). The impact of these changes on the storm petrels is poorly understood. The current status of storm petrels at Tullaberga Island is unknown. This study estimated the size of the breeding population at all three sites by determining burrow densities, and a burrow-scope was used to determine occupancy. Burrow density was found to be related to vegetation type and other habitat factors. This study has highlighted important information on the breeding habitat of the white-faced storm petrel and the implications for management are discussed.

An evidence-based approach to podiatry workforce enhancement and service provision in Western Victoria

Aims & rationale/Objectives : The objectives of this workforce and service enhancement project include: (i) establishing the magnitude of podiatry needs; and (ii) developing a model that can be used to enhance podiatry workforce and podiatry services.
Methods : Surveys to podiatrists and health agencies to determine vacancies, waiting lists, work practices and recruitment methods. Desktop analysis of predictive data for burden of disease and population changes per local government area (LGA). Meetings with podiatrists and their professional association, health care agencies, universities, and Local and State Governments.
Principal findings : Results showed
Long podiatry waiting lists (up to 12 months)
Podiatry vacancies and service gaps
Absence of qualified foot assistants
A high chronic disease burden
A population age mix that is predicted to change dramatically over the next 25 years in favour of those who are 60 years of age or older
Ineffective recruitment methods
The workforce enhancement model that emanated from the meetings with the steering group includes podiatrists as well as auxiliaries such as foot-care assistants who work together in an interprofessional model of care that expands across the region. In addition to training foot-care assistants and the development of a podiatry teaching clinic to enhance student placement, the model builds onto a current continuous professional development program for allied health professionals.
Discussion : Although the allied health workforce (including podiatry) is playing an increasingly important role in the prevention and treatment of chronic diseases, rural areas in particular are disadvantaged by recruitment and retention problems. The podiatry workforce shortage is compounded by ageing populations. Age is associated with increased podiatry usage due to chronic diseases such as diabetes, cardiovascular disease and osteoarthritis.
Implications : A strategic plan developed in consultation with stakeholders aims to improve rural podiatry services in a sustainable manner. The project will be implemented when adequate funding is allocated this year and will be evaluated on its impact on services.

Strategic public land use assessment and planning in Victoria : over 30 years of trailblazing but where to from here?

Conflict over the appropriate uses and management of public land have been a feature of the Australian political landscape for at least the past 30 years. While various attempts have been made to establish land use assessment and planning institutions in various jurisdictions, the success of these often short lived attempts at institutional approaches for managing land use conflict have been patchy at best. The experience in the State of Victoria has been somewhat different, with public land use assessment and planning having been informed by a series of independent statutory bodies since 1970 (the Land Conservation, Environment Conservation, and Victorian Environmental Assessment Councils). To some degree at least the value of this approach is indicated by the extent to which Victoria’s bioregions are now protected in conservation reserves. However, while there has always been a statutory body in operation, the roles and responsibilities of these bodies have been subject to significant legislative change, with existing bodies replaced by new bodies in 1997 and 2001. Justifications for these reforms included changing circumstances and new understandings about environmental management, as well as changing views about public administration. As a way of contributing to enhancing the design of institutions for mediating land use conflict and contributing to sustainable land use and management, this paper investigates the lessons that can be learnt from the Victorian experience by examining the implications of the changing roles and responsibilities of these institutions, and then discussing possible future directions for strategic land use planning.
