Dr Birgita Hansen
Senior Research Fellow
Birgita brings to the CeRDI team extensive experience in ecology and environmental management, contributing to improving the management and dissemination of biodiversity knowledge. Her research interests lie in understanding the ecological response of birds to modification of their habitat, with a strong focus on migratory shorebird monitoring and conservation. She is currently leading the Food Agility CRC Better Data for Better Decisions Constellation, which aims to improve the management and sharing of agricultural data, and working toward adoption of FAIR data principles. Her past research has included studies into riparian restoration in agricultural landscapes and waterbird monitoring at local and continental scales. Birgita is a long-term member of the volunteer-run Victorian Wader Study Group and an executive committee member of the Australasian Wader Studies Group. She is a member of the IUCN Woodcock and Snipe Specialist Group and the BirdLife Australia Research and Conservation Committee. Birgita completed her PhD at Monash University in 2009 on conservation genetics of Leadbeater's possums.
A commitment to improving the management of waterways, wetlands and estuaries for the conservation of birds is the motivation behind research being conducted by Dr Birgita Hansen. Birgita has a long-standing history of working with volunteers in shorebird conservation. She has many years' experience in the field of ornithology, specialising in wetland and waterbird conservation and management. Her research has made an important contribution to policy and planning in fields of conservation genetics, riparian restoration and waterbird conservation. She is currently leading projects in the agrifoods sector on digital adoption and improving on-farm decision making through better access to data and knowledge. She is also leading a collaborative project investigating the movement patterns and habitat use by Latham's Snipe. This study is part of a larger research programme she is developing aimed at improving the management of wetlands in western Victoria by working in close collaboration with community groups, private land owners and Natural Resource Management bodies.

Consulting and other research activities
In 2021, Birgita contributed to an expert review panel for the Coorong Infrastructure Investigations Project. In 2016, she lead a collaborative project with BirdLife Australia, the University of Queensland, the Arthur Rylah Institute (DELWP) and the AWSG to revise the East Asian-Australasian Flyway population estimates for 37 migratory shorebird species listed under the Environment Protection and Biodiversity Conservation Act. This project was funded by the Australian Government Department of the Environment and Energy.
Birgita is on the editorial board of Emu Austral Ornithology, Corella and Stilt (the shorebird journal of the East Asian-Australasian Flyway). She was the editor-in-chief of Stilt between 2011 and 2016. She is actively engaged in shorebird monitoring and conservation as both a volunteer and a professional.
Birgita also periodically provides expert advice and targeted field survey for waterbird, shorebird and other avian monitoring and research programs.
