Potential Groundwater Dependent Ecosystem (GDE) - Species Tolerance Grid

Brief description

Potential Groundwater Dependent Ecosystems (GDE) are ecosystems identified within the landscape as likely to be at least partly dependent on groundwater.

In 2011-2012 a species tolerance model was developed by Arthur Rylah Institute, collaborating with DPI, to provide a relative measure of sensitivity of those ecosystems to changes in groundwater availability and quality. The output was a species tolerance grid for Victoria.

Each GDE map unit has been assigned a species tolerance value based on the median of it's contributing grid cells.
