Title

Marine Biodiversity Values (MBV) 

Alternate title

MARINE_BIO_VALUES 

Purpose

DEECA made the MBV map by assessing data and spatial information. The map ranks all locations across Victoria's marine waters and 5km inland, from low (0) to high (100). A location with a high value (close to 100) supports many different marine and coastal biodiversity features. These are important areas, few or no other locations have the same features.

Statement

Biodiversity features included in the analysis are limited by the inclusion criteria and do not represent the full biodiversity in Victoria’s marine and coastal environment, estimated to support more than 12,000 plant and animal species (DELWP 2020). Any applications of this map should consider implications of the many biodiversity features that are not included and the resulting limitations of the map. A thorough assessment of the inclusion criteria, particularly defining key biodiversity features, is needed to progress this work into the future. Once a full features list was determined based on the biodiversity features inclusion criteria above, spatial data was sought and acquired from various sources and converted using ESRI ArcGIS Pro (2.8.8) software for processing methods into a uniform format that can be consistently assessed. In cases where multiple data sources for 1 species existed, multiple data products were integrated to create a representative statewide distribution layer. This included any areas or sites identified in the sources below as significant for ecological function or life-history of a species, for example breeding or foraging areas. The data quality of each source was also assessed against criteria to clarify the limitations of this first assessment and enable prioritisation of future data needs given the general paucity of high integrity data within the marine environment. Data sources examined and included in this first assessment include: - Biologically Important Areas (BIAs) -DCCEEW - BirdLife Australia - CoastKit (DEECA) - NatureKit (DEECA) - Species of National Environmental Significance (SNES) (DCCEEW) - Victoria’s Biodiversity Atlas (VBA) (DEECA)
