Dry Creek salt fields

In late 2020 dieback of mangrove and saltmarsh habitats south of St Kilda was observed. In March 2021, the Department for Environment and Water (DEW) developed a mapping approach to measure the extent and composition of the dieback.

This map viewer presents the datasets compiled and used in the analyses in a format where users can pan, zoom and compare. Refer to the  technical  or  summary  report for details.

List of datasets presented:

• Bird & dolphin sanctuary boundaries
• Salt field evaporation pans & sections
• St Kilda mangrove boardwalk / walking trail
• January 2022 dead vegetation mapping
• September 2021 dead vegetation mapping
• March 2021 dead vegetation mapping 
• 2021 hyperspectral vegetation types
• 2018 - 2021 Vegetation Index change (dNDVI)
• March 2021 imagery - true colour & colour infrared
• 1997 vegetation mapping - integrity & short description
• 1997 vegetation mapping - aerial photos
• 2021 LiDAR elevation surface - Digital Terrain Model (DTM)
