  • Hydrographs from over 2000 state observation bores were reviewed in order to group bores which have a similar water level trend and are screened in the same aquifer. The groupings of observation bores are referred to as 'suites' and are classified according to the Upper, Middle, Lower and Basement aquifers aligning with the Victorian Aquifer Framework. By applying a statistical technical, a normalised hydrograph was developed for each suite using the observed water levels from all bores within the suite. This hydrograph is representative of the groundwater trend within the suite. A spatial boundary has been created for each suite which encompasses all bores within the suite. The boundaries were manually constructed and cover the extent of the mapped aquifers.

  • This dataset is the Victorian Aquifer Framework (VAF) Salinity Distribution. It refers to the salinity distribution for Aquifer Number of 105 (Upper Tertiary Aquifer (Fluvial)). The salinity distributions reflect the beneficial use segments prescribed in the State Environment Protection Policy (Waters) (2018) Please refer to the master metadata record VAF 'Victorian Aquifer Framework (VAF) Salinity Distribution for detailed information.

  • This dataset is the Victorian Aquifer Framework (VAF) Salinity Distribution. It refers to the salinity distribution for Aquifer Number of 111 (Lower Tertiary Aquifer).

  • This dataset is a subset of the Victorian Groundwater Data Inventory, developed by DELWP. The Data Inventory collated available data relating to four themes: groundwater recharge, aquifer/aquitard properties, groundwater use and aquifer/aquitard thickness. Information has been sourced from 65 hydrogeological studies and contains a spatially enabled representation of data coverage. This dataset represent the Aquifer Properties component of the Data Inventory.

  • The Statewide Marine Habitat Map 2023 was developed by DEECA applying novel machine learning methods that model and predict habitat distributions as well as a mosaic of former mapping products (listed below). The Statewide map represents 24 marine and coastal habitats complexes at Level 3, Victoria's Combined Biotope Classification Scheme (CBiCS) described by Edmunds and Flynn (2015, 2018; 2021). The final map comprises of 83% its area from predictive modelling, with the remaining 17% of area from synthesised existing habitat maps. Predictive Model: A total of 32,998 habitat survey sites (ground-truth records) were used within the model, along with 28 environmental properties mapped at a 10m resolution (including a Digital Elevation Model DEM (VCDEM2021), computed benthic terrain characteristics (toolkit: Walbridge et al. 2018), Chlorophyl a (IMOS 2000a), Sea Surface Temperature SST (IMOS 2000a), Net Primary Productivity NPP (IMOS 2000b), Sediments (Geoscience Australia; Li et al. 2011a,b,c), waves (Liu et al. 2022). To predict the distribution of habitats across Victorian waters the powerful and flexible Random Forest machine learning algorithm was applied. Random Forest is an ensemble model using bagging as the ensemble method and decision trees as the individual model (Breiman 2001). The modelling produced an accuracy (Out-of-bag) of 89%. Map Synthesis: A mosaic of former mapping products that provided higher resolution mapping by aerial imagery, field observations and high-resolution modelling were integrated into the map, classifying habitat according to the CBICS habitat classification scheme at level 3.

Applications: The Statewide Marine Habitat Map 2023 provides broad habitat complexes across the state and provides greater knowledge of the ecological diversity across Victoria¿s waters. The map should be used at broad scales of >25 m, and where information of larger habitat complexes is needed. This work can support the management of large-scale habitats, their condition, marine spatial planning, strategic management prospect (SMP), FeAST risk assessments, and other broad scale applications to support management decisions across Victoria. The habitat model and resulting map provides an updated broad-scale habitat map across Victoria¿s state waters and provides a baseline for future data to build upon.

  • This layer has been derived from LOG_SEASON and represents the spatial extent of the most recent timber harvesting activity recorded for any given area in State forest. Where harvest events overlap previous harvesting events the most recent harvesting event is shown. The layer stores details of the last time an area was known to be harvested, the species harvested and the harvesting method used. The dataset has been updated with the 2021-22 information. Complete to 30 June 2022
