This dataset identifies high ecological value waterways and water dependent ecosystems for the Central Coast of NSW, covering 29 coastal catchments. The purpose of the dataset is to identify strategic priorities for protecting and improving the health of high value waterways and water dependent ecosystems in the catchment. The map shows areas where waterways and water dependent ecosystems are defined as high ecological value, based on the definitions, guidelines and policies under the Environment Protection and Biodiversity Conservation Act 1999, Biodiversity Conservation Act 2016, Fisheries Management Act 1994 and/or Water Management Act 2000. The water dependent ecosystems consist of wetlands, and flora and fauna that rely on water sources (including groundwater). The dataset does not include vegetation communities dependent on surface waters. The dataset integrates 28 data layers/indicators being used by the State Government to define high value and 23 indicators are present in this region (see Attachment 1: Datasets describing high value waterways and water dependent ecosystems in the Central Coast, NSW). The individual indicators have not been ground-truthed and it is recommended that field assessments and/or a comparison to local mapping be undertaken prior to any decisions being made. The dataset was created by initially placing a 1-hectare hexagon grid over the relevant boundary area and attributing the grid with either ‘Absent’ or ‘Present’. This represents an occurrence only of high value water dependent ecosystems layers within the hexagon grid. The ‘HEVlyr’ field provides a count of the number of layers within the hexagon. A value of zero (0) represents Absent, values of greater and equal to one (1) represents the Presence of high ecological value assets. The values DONOT indicate the significance of the area, i.e., a value of 1 is no less significant to a higher value. Where layers are Present, please contact data steward for details relating to the underpinning datasets.
