About the report
The tropical rivers of northern Australia are under increasing pressure due to environmental threats and human activities. The objective of this sub-project (sub-project 2) of the Tropical Rivers Inventory and Assessment Project (TRIAP) is to develop a risk assessment framework applicable to the key focus catchments and significant locations that meet stakeholder needs, within the region of the TRIAP. In addition to providing a broad overview of the major pressures on tropical Australia’s aquatic ecosystems, the key component of this study is more detailed risk assessments for the focus catchments, being the Daly River (NT), Flinders River (Qld) and Fitzroy River (WA). Throughout this sub-project, stakeholders will be involved in providing input and feedback.
This paper firstly describes the generic elements of ecological risk assessment then details the process that will be followed for the project and the approaches that will be used.
