Dr Kate Brandis

Role: Research Fellow
I am a joint research fellow with the Centre for Ecosystem Science, and the Australian Nuclear Science Technology Organisation (ANSTO). I am the project leader for the Feather Map of Australia which uses elemental and stable isotope techniques to track the movements of waterbirds between wetlands in Australia (www.ansto.gov.au/feathermap).
I also work on a range of projects including monitoring the reproductive success of colonially breeding waterbirds in response to environmental flows, assessing the impacts of water resource development on colonial waterbird breeding in the Murray Darling Basin, determining water requirements for colonial waterbirds, waterbird diets, and the application of elemental and stable isotope analysis to a wide range of ecological and biological problems.

Fields of Research: Colonial waterbird breeding, wetland ecology, environmental flow management for ecological outcomes, stable isotope ecology, waterbirds at a landscape scale.

Lyons et al. 2018 Bird interactions with drones, from individuals to large colonies

Abstract

Drones are rapidly becoming a key part of the toolkit for a range of scientific disciplines, as well as a range of management and commercial applications. This presents challenges in the context of how drone use might impact on nearby wildlife, especially birds as they might share the airspace. This paper presents observations (from 97 flight hours) and offers preliminary guidance for drone-monitoring exercises and future research to develop guidelines for safe and effective monitoring with drones. Our study sites spanned a range of arid, semi-arid, dunefield, floodplain, wetland, woodland, forest, coastal heath and urban environments in south-eastern and central Australia. They included a nesting colony of >200 000 Straw-necked Ibis Threskiornis spinicollis, the largest drone-based bird-monitoring exercise to date. We particularly focused on behavioural changes towards drones during the breeding season, interactions with raptors, and effects on birds nesting in large colonies—three areas yet to be explored in published literature. Some aggressive behaviour was encountered from solitary breeding birds, but several large breeding bird colonies were surveyed without such issues. With multi-rotor drones, we observed no incidents that posed a threat to birds, but one raptor attacked and took down a fixed-wing drone. In addition to providing observations of interactions with specific bird species, we detail our procedures for flight planning, safe flying and avoidance of birds, and highlight the need for more research into bird– drone interactions, most notably with respect to territorial breeding birds, safety around large raptors, and the effects of drones on the behaviour of birds in large breeding colonies.

Brandis et al. 2018 Decline in colonial waterbird breeding highlights loss of Ramsar wetland function

Abstract:

Water resource development on rivers significantly affects life cycles of species reliant on wetlands. However, assessing ecological impacts is often difficult because they are realised over long-time periods and large spatial scales, particularly on highly variable dryland rivers. Thirty percent of all Ramsar wetlands are in drylands. We examined the effects of diversions of water upstream on colonial waterbird breeding at the Narran Lakes, supplied by a highly variable dryland river. Narran Lakes is an important Ramsar-listed wetland in Australia for its provision of habitat for wetland fauna during key life history stages, including colonially breeding waterbirds. We use historical ibis breeding data over five decades (1970–2016) to determine the flow requirements for colonial waterbird breeding and modelled the impacts of water resource management options (current and restoration) on breeding. We identified thresholds (> 154,000 ML in 90 days with a secondary threshold of > 20,000 ML in the first 10 days) of river flow volume necessary to stimulate breeding. Water resource development reduced the frequency of large flows resulting in ibis breeding by 170%, from 1 in 4.2 years to 1 in 11.4 years. Restoration efforts by government to recover water for the environment was predicted to improve colonial waterbird breeding frequency associated with large flow events to 1 in 6.71 years, representing a 59% reduction from pre-development periods. Our framework has global application as a method for identifying long-term impacts of water resource development on key Ramsar wetland areas. This is important, as few mechanisms exist for assessing impacts and identifying restoration options on the listed criteria for many Ramsar wetlands.

Brandis et al 2014 Assessing the use of camera traps to measure reproductive success in Straw-necked Ibis breeding colonies

Summary. Nest monitoring may influence reproductive success and rates of predation. This study compared data from two methods of monitoring nests — repeated visits to nests by investigators and collection of data by camera traps — in Straw-necked Ibis Threskiornis spinicollis breeding colonies in the Murrumbidgee catchment in New South Wales. There was no significant difference in reproductive success between nests monitored by these two methods. These data show that (1) nest monitoring using camera traps is a valid survey method that reduces the need for investigators to engage in intensive and costly monitoring in the field, and (2) there was no detectable interference from repeated visits to nests by investigators on the reproductive success of ibis.
