Dr Margaret Brock


Margaret is a wetland ecologist with broad interests in the conservation and management of aquatic ecosystems. After most of her life on “the mainland” she moved to Tasmania in 2006. Her early days were in Canberra and family holidays to Western Victoria meant crossing the River Murray where observing water level fluctuations and human uses of the river and its tributaries set the scene for her career.

Studies in Canberra (BSc at ANU and  DipEd at UC) led her to South Australia where her fascination with the Coorong, and the plants of its salt lakes and salt marshes developed during her PhD(UAdel) days.

Time in WA consolidated her interest in salt lakes and heightened her awareness of land and water management issues before moving to the New England Tablelands where the upper catchments of both the Murray Darling Basin and the coastal rivers fuelled a fascination with freshwater upland wetlands, both temporary and permanent.

 Margaret moved into design and delivery of science for management in 1999 from a 25 year teaching and research career in wetland ecology and management in universities in NSW, WA and SA. Her studies of the ecology, conservation and management of aquatic ecosystems are collaborative and focus on wetland plants and processes at population, community and landscape levels. The response of aquatic plants to changes in water regime and increase in salinity is a particular focus.

Her management interests also include the policy and practice of conservation of endangered species and communities. Margaret is co-author with Andrew Boulton of the textbook  ‘Australian Freshwater Ecology – processes and management’ Gleneagles Publishing 1999. Advisory roles have included WWF Advisory Committee, Threatened Species Scientific Committees (NSW and Federal). She was President of the Australian Society for Limnology (ASL) 1994-95 and was awarded the ASL medal for contributions to Australian Limnology in 2008.


Peter Shadie


Born and raised on Sydney’s northern beaches. Peter graduated from the University of Sydney in 1979 with qualifications in Botany and Zoology and took up what was to become a 20 year career with the New South Wales National Parks and Wildlife Service.  Working at the grassroots level he progressed through the ranks from Park Ranger to Park Superintendent, District Manager and Regional Operations Manager, holding down a number of other senior managerial positions within the agency.  Peter has extensive experience in the establishment, planning and management of protected areas across a wide range of Australian contexts. 

In early 1999 Peter was seconded as Executive Director with the International Union for the Conservation of Nature (IUCN) based in Switzerland.  This assignment focused on planning and delivery of the Vth World Parks Congress which took place in September of 2003 in Durban South Africa.  The once a decade Parks Congress is the largest global event for parks and sets the global agenda for protected areas.  Peter planned, organised and delivered all aspects of the event including raising over $6m US to support protected area work around the world.   

Working with IUCN’s global Protected Areas Programme, Peter has protected area experience in a wide variety of contexts across 5 continents.  He has been involved in the development of policy, provision of technical advice and the integration of protected area issues within international environmental agreements, such as the Convention on Biological Diversity, Ramsar and UNESCO World Heritage Conventions.  He is a member of the World Commission on Protected Areas and has worked closely with the Commission’s Executive.  He has sat for 8 years on the IUCN World Heritage Panel which evaluates annual World Heritage nominations and makes recommendations on inscriptions to the prestigious World Heritage WH List. 

Since 2006 Peter has led IUCN’s work on protected areas in Asia.  Based in Bangkok, the Regional Protected Areas Programme aims to promote an effectively managed, representative system of marine and terrestrial protected areas throughout the 23 countries of East, South East and South Asia.  Throughout 2007 Peter also acted as the Head of IUCN’s Regional Water & Wetlands Programme ensuring strong integration of protected area and water & wetlands conservation issues.
