Ecological assets of the Gwydir wetlands and floodplain 2008 VIS_ID 3923

Brief description

## **Abstract**

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.



The 2008 map of the vegetation communites of the Gwydir wetlands and floodplain (Bowen and Simpson 2009) was annotated for flooding frequency history, ecological importance and hydro-ecological functional group to determine the spatial distribution of ecological assets to inform the Valley Wide Floodplain Management Plan for the Gwydir.
