HWS2018 Habitat suitability modelling results for Macroinvertebrates

Data describes habitat suitability modelling (HSM) results for macroinvertebrates 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. The data was used to estimate the scores for macroninvertebrates presented in the HWS for three scenarios:Current: habitat suitability under current conditions (i.e. 2014).Current trajectory: habitat suitability under urbanisation and climate change scenarios if current management approaches continue.Target trajectory: habitat suitability 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.Data has also been captured for a range of modelled HSM scenarios involving revegetation, stormwater management and climate change. Primary purpose is for waterways planning and analysis.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. This layer was developed by GraceGIS using Melbourne Water layers as inputs. 2. Results from Habitat Suitability Modelling for the Healthy Waterways Strategy 2018. Further reading: Chee et al.
