The 23 Conservation Management Zones of Australia are geographic areas, classified according to their ecological and threat characteristics. The zones are also aligned with the Interim Biogeographic Regionalisation of Australia. The Conservation Management Zones provide a way of understanding Australia’s natural environment that will assist in long-term conservation planning and help the Australian Government to better design, deliver and report on Natural Resource Management (NRM) investments, including ensuring alignment of national NRM priorities with local action. The Conservation Management Zones also provide a filter through which to make national environmental and socio-economic data regionally meaningful, accessible and comprehensible to all. They provide a framework for gathering on-ground knowledge and expertise about the environment. This will improve information flow to the Australian Government and other key decision makers about regional NRM requirements, best practice management, emerging NRM issues and knowledge gaps. The Conservation Management Zones do not represent any change to existing administrative boundaries or governance structures, but aim to support the NRM and wider community to cooperatively manage environmental assets across boundaries, where they share common threats, ecological characteristics and stakeholders. The project builds on the Interim Biogeographic Regionalisation of Australia (IBRA) which has been used to support planning of the National Reserve System, but consolidates the 85 mainland IBRA regions into 23 Conservation Management Zones, where IBRA regions share common characteristics. Further information and profiles describing the zones can be accessed through the Department of the Environments web site at - https://www.dcceew.gov.au/environment/biodiversity/conservation-management-zones

Land Systems (based upon groupings of Soil Landscape Map Units) are broad and readily recognisable landscape areas defined by particular and distinctive patterns of land use, geology, topography, soils and vegetation within a limited climatic range. A Land System Report is available for each Land System.

This dataset shows Proclaimed Landslip Zones (A and B) of Tasmania. These zones are defined under the Mineral Resources legislation.

The rangelands are those areas where the rainfall is too low or unreliable and the soils too poor to support regular cropping. They cover about 80% of Australia and include savannas, woodlands, shrublands, grasslands and wetlands. The rangeland boundary as defined by the Australian Collaborative Rangeland Information System (ACRIS) is based on mapped bioregions and, specifically, those largely undisturbed or natural bioregions (Interim Biogeographic Regionalisation for Australia, IBRA version 7.0) within Western Australia, South Australia, New South Wales, Queensland and the Northern Territory. The boundary in Queensland was modified according to some local government (i.e. shire) boundaries. The boundary was jointly defined by members of the ACRIS Management Committee and revised by the ACRIS Management Unit based on IBRA v7 mapping.STAT7 is the ACRIS numbering of states based on IBRA7. STAT6 is the ACRIS numbering of states, based on IBRA6.1.

Interim Biogeographic Regionalisation for Australia (IBRA) version 7.0 represents a landscape based approach to classifying the land surface of Australia. 89 biogeographic regions and 419 sub regions have been delineated, each reflecting a unifying set of major environmental influences which shape the occurrence of flora and fauna and their interaction with the physical environment across Australia and its external territories (excluding Antarctica). IBRA Version 7.0 data consists of two datasets. IBRA bioregions, which is a larger scale regional classification of homogenous ecosystems, and sub regions, which are more localised. IBRA Version 7.0 is the result of both significant changes to certain IBRA 6.1 boundaries, plus refinement of other boundaries due to better data availability amongst some states and territories, and alterations by the states/territories along state borders. The updated boundaries were jointly defined by the Commonwealth, State and Territory nature and conservation agencies. In this respect refinements were carried out to all mainland jurisdictions with significant changes in Queensland and South Australia. In addition, the dataset was also updated to more closely conform to the Geoscience Australia 1:100K State borders, and a standard coding/naming convention introduced (for both regions and sub-regions) resulting in differences to both names and codes used in earlier IBRA Versions.Various sources were used to delineate islands - these included the GA100K Admin layer plus the Australian Maritime Boundaries dataset, a Coral Sea dataset (held in ERIN) and the GA Commonwealth Fisheries 2006 dataset.

Tasmania was separated into seven regions for the purposes of land system mapping for the period 1978-1989. Non-unique land systems were developed based on six descriptor classes (geological period, geological rock type, rainfall, vegetation, elevation, and differences in dominant soils. Within each land system, land components are described which present examples of soil and vegetation variation across topographic sequences (proportion estimates, but unmapped boundaries). Land Systems are considered to have a nominal scale of 1:100 000. Regions were mapped separately (as below), and amalgamated to form a digital statewide coverage: Land Systems of Tasmania Region 1: King Island. Land Systems of Tasmania Region 2: Flinders Island. Land Systems of Tasmania Region 3: North. Land Systems of Tasmania Region 4: North East Land Systems Survey of Tasmania Region 5: Central Plateau. Land Systems Surveys of Tasmania Region 6: South, East and Midlands Land Systems of Tasmania Region 7: South West.
