Parks Australia's Natural Values Ecosystems (NESP MaC 1.3)

The Parks Australia Management Effectiveness (ME) system - previously MERI - is underpinned by a controlled, common language that provides a nationally consistent lexicon for a) Natural, cultural, and heritage values; (b) Social, cultural, and economic benefits; (c) Activities and anthropogenic pressures; and (d) Biophysical, and social and economic drivers.

The Natural Values component of the common language is defined at three levels: 1) ecosystem complexes; 2) ecosystems; and 3) ecosystem components. This map shows the Ecosystems (tier 2) component of the Natural Values, and delineates features by habitat and depth for the Australian Exclusive Economic Zone (EEZ).

This version (2022) of the National Values Ecosystems dataset uses Geoscience Australia's 250m resolution Australian Bathymetry and Topography Grid, 2009 (https://dx.doi.org/10.4225/25/53D99B6581B9A) as the basis for the map. See Hayes et al. 2021 and Dunstan et al. 2023 for a full definition of Natural Values Ecosystem terms, input datasets used, and processing steps involved with the creation of this map.

Note that this dataset uses a combination of input data sources and interpolates where data gaps exist. The common language adopts a functional, largely geo-physical perspective to define surrogates for marine ecosystems. This dataset is not a substitute for a validated habitat map (see Seamap Australia National Benthic Habitat Layer: https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/4739e4b0-4dba-4ec5-b658-02c09f27ab9a), but has a national coverage and provides valuable broad-scale categorisation of marine ecosystems in Australian waters.
