Dataset

Terrestrial Groundwater Dependent Ecosystem (GDE) Density

This dataset is based on the Potential Terrestrial Groundwater Dependent Ecosystem (GDE) mapping undertaken by Dresel et al. (2010). Dresel et al. (2010) recognised that the dataset over estimated the occurrence of mapped terrestrial GDEs. For this reason, the GDE dataset was refined to provide information regarding the relative density of GDEs across the State. Areas of very low GDE density were assigned less weighting than an areas with very high GDE density GDE. This provided a suitable solution to the problem of mapped GDE over estimation.
