In the current assessment for NSW, the HEVAE consists of four key criteria which include diversity, distinctiveness, naturalness and vital habitat. Therefore, the HEVAE instream value layer is a combination of four individual criterion layers. The final or overall HEVAE score is determined for each River Style® reach. This is calculated by adding together the final scores for each criterion (Diversity, Distinctiveness, Naturalness and Vital Habitat) summarised below. The Vital Habitat criteria was not able to use in the coastal HEVAE assessment due to lack of suitable data and is not used in determining coastal HEVAE outcomes.This score is then standardised by dividing by the maximum combined HEVAE score for a whole catchment’s river reaches to provide an even spread of score outcomes between 0 (lowest) and 1 (highest). The first version of this assessment was completed in 2016. The Distinctiveness criteria were further updated in 2018 by including the predicted threatened fish species distribution data (MaxEnt modelled data) provided by Department of Primary Industries and Regional Development- Primary Industries(Fisheries). In this version, the final or overall HEVAE scores where then recalculated after this process.Freshwater diversity is described in HEVAE as: The aquatic ecosystem exhibits exceptional diversity of species (native/migratory), habitats, and/or geomorphological features/processes.State-wide spatial data was available for fish and macroinvertebrate diversity, hence the diversity layer consists of these parameters. Statewide Fish Community Status (fish diversity) layer was sourced from NSW Department of Primary Industries (DPI) Fisheries and this data was used for the inland and coastal diversity assessment. For inland areas (Murray-Darling Basin catchments),Macroinvertebrate data were obtained from the NSW DCCEEW – Biodiversity and Conservation Science (BCS) and consisted of the AUSRIVAS NSW site sample data. A GIS point layer was created based on site data and number of macroinvertebrate families. The macroinvertebrate Families attributes were transferred from point layer to the River Styles® layer. After some statistical analysis, the River Styles® reaches were then assigned with macroinvertebrate biodiversity scores (0 (Family numbers ranged from &amp;lt;10 to 24) to 1 (Family numbers ranged from 23+ to 34+)). For coastal HEVAE areas,predicted outcomes for macroinvertebrates were developed by NSW DCCEEW – BCS (Turak et al 2010), the predicted outcomes are termed as Conservation Priority Value and spatial data was supplied to us. Predicted outputs are derived for river sections and identify areas of low to high conservation value because of the significance of their biodiversity for a region. The Conservation Priority Value are classified into five categories and are weighted for diversity analysis as follows: Very high = 1; High = 0.5; Moderate (fair) = 0.25; and remaining scores for poor and very poor = 0.Distinctiveness is a characteristic of waterway value assessments that can include rare or threatened species, populations and communities, ecosystems and habitats and water chemistry. Similar Distinctiveness data was collated for both inland and coastal HEVAE assessments. For the NSW instream value assessment under the HEVAE framework, Distinctiveness focuses on threatened species such as fish, frogs, mammals, waterbirds, plants, and other aquatic species; endangered ecological communities (EEC); endangered populations and rare river style information. Recorded, known and predicted distributions of threatened species, population and EEC were considered for the purpose of HEVAE analysis.Naturalness is described as the ecological character of the aquatic ecosystem which is not adversely affected by modern human activity. Similar Naturalness data was collated for both inland and coastal HEVAE assessments. Naturalness focuses on Geomorphic condition (River Style Value), Hydrologic Stress, Catchment Disturbance Index (CDI), Macroinvertebrate AUSRIVAS O/E bands, and river reaches within National Park Estate. Relevant spatial data were accessed from DCCEEW –Water Group internal Enterprise Database. DCCEEW – Water Group is custodian of spatial layers for River Style®value, hydrologic stress, catchment disturbance index with specific distribution value scores. The distribution scores of different layers were transferred into the River Style® spatial layer of the catchment area using spatial analysis techniques.Vital Habitat is described as an aquatic ecosystem that provides vital habitat for flora and fauna species. For the NSW instream value assessment under the HEVAE framework Vital habitat has only been determined for inland areas (Murray-Darling Basin catchments), Vital Habitat focuses on three attributes: DIWA/Ramsar wetlands, large woody debris (LWD) and dissolved organic carbon (DOC). DIWA/Ramsar wetlands spatial data were accessed from DCCEEW-Water Corporate Database. The LWD and DOC layers were derived from the River Style® mapping, and the Riparian Woody Extent raster dataset. Riparian woody vegetation of 60% cover was selected as a surrogate measure of both LWD and DOC. The Riparian Woody Extent raster dataset derived from the NSW Interim native vegetation extent layer (DECC 2008) and was accessed from the DCCEEW-Water EDB. The lack of suitable spatial data and attributes in coastal areas has prevented vital habitats from being determined in coastal areas. It is hoped the omission of coastal vital habitat is rectified in future iterations of the NSW freshwater HEVAE product.</SPAN></P></DIV></DIV> This layer has been created to provide an indicative estimation of Instream Value of the NSW river system.
