Metropolitan Coal Mine Vegetation Monitoring, Helensburgh
We undertake bi-annual monitoring of vegetation communities within the catchment of the Woronora Special Area for Metropolitan Coal in Helensburgh, New South Wales.
Vegetation includes ridge top, upland swamp and riparian vegetation communities at over 50 sites. Potential impacts associated with long-wall mining subsidence are assessed at each site.
Monitoring commenced in spring 2008 and involves systematic floristic surveys, visual inspections and population monitoring of targeted indicator plant species.
Data collected are statistically analysed to identify any changes in vegetation cover, condition and floristic diversity over time and any changes between impact and control sites.
