Data describes habitat suitability modelling (HSM) results for fish in streams. The data was developed by University of Melbourne through the Melbourne Waterways Research Practice Partnership as part of the development of Melbourne Water’s Healthy Waterways Strategy 2018 (HWS2018). Analysis has been undertaken across the Melbourne Water operating region, where the operating region has been divided into 16,346 sub-catchments. Of these 16,346 subcatchments, 8233 contain Melbourne Water waterways. The results are presented for each of these 8233 reaches for these HWS scenarios: Current: habitat suitability for fish under current conditions (i.e. 2014).Current trajectory: habitat suitability for fish under urbanisation and climate change scenarios if current management approaches continue. Target trajectory: habitat suitability for fish given urbanisation and climate change (as for current trajectory), together with (a) delivery of performance objectives of the Healthy Waterways Strategy and (b) achievement of environmental condition scores as described in the Catchment Programs of the Healthy Waterways Strategy. Results are presented as: Stacked probabilities, i.e. habitat suitability all 13 native fished species added together. These stacked probability values were used in the HWS to provide a fish value score each reach and sub-catchments.Results are also provided for all 22 fish species. Presentation of habitat suitabilty model results for fish from the Healthy Waterways Strategy 2018.

Habitat Suitability Model results have been thoroughly reviewed and are considered fit for purpose (i.e. for waterway planning). This data set covers the entire Melbourne Water region with the exception of very small areas close to Port Phillip Bay or Western Port. For example, there are small areas of French Island which are not captured.

This data set was created using: 1. Streams dataset for the Healthy Waterways Strategy 2018 (developed by GraceGIS using Melbourne Water layers as inputs), and 2. Results from Habitat Suitability Modelling for the Healthy Waterways Strategy 2018.
