Purpose

The statewide marine habitat map 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 state habitat map addresses the Marine & Coastal Strategy 2022, building knowledge to improve the condition and ecological connectivity of habitats, and protecting Victoria¿s environment - Biodiversity 2037, improving our knowledge of habitats and their extent to support their protection and restoration.

Missing Data

Victoria's marine environment and coastal habitats. Some small data gaps as a relict of the modelling process and availability of environmental predictor data. Completeness Verification: Habitat distribution model prediction using random forest machine learning tools from 32,998 ground-truthed habitat records and other digitised compiled datasets. 

Excess Data

Classified to Level 3 Habitat Complexes within the Combined Biotope Classification Scheme (CBICs) 

Attribute Quality

Modelled estimatation of habitat disribution using best available data up to 2021 see report. 

Positional Accuracy

Modelled to coordinate system: VICGRID94 Due to modelling and digitisation uncertainties the maps should be used at broad scales of over 25m for decision making. Scale range on CoastKit available at 1:100.000 

Lineage

Statement

Dataset Source: PPB Habitat model 2021 provides an updated broad-scale habitat map across Port Phillip Bay, which has applied new machine learning techniques Previous mapping of Port Phillip Bay has provided insight into habitats across the region, with the latest map produced in 2016 (Edmunds & Flynn 2018). Since then, additional benthic survey data and data on environmental predictors has developed which increases the capacity to improve model habitat distributions and extent. The Open Coast statewide marine habitat map (excluding PPB) developed by Deakin Marine Mapping lab using a range of techniques including digitisation of polygons and has been compiled using a compilatiom of various datasets including Boon et al. (2011). Deakin Marine Mapping (Young M et al, 2018). GeoHab Victoria Estuaries Geomorphology (2010). Deakin Marine Mapping (Zavalas, R et al. 2018), DELWP wetlands (1994), Monk et al 2011, Roob and Ball (1997), Ford et al 2016, Edmunds and Flynn (2015), Blake and Ball (2001), Poore (1992), Cohen et al (2000). The map has later been reclassified to CBICS habitat classification scheme at broad-scale level 2 and 3. Dataset Originality: Primary & Derived
