As part of Phase Two of the National Landcare Program (NLP) the Australian Government's natural resource management (NRM) investments will be delivered within NLP Management Units. The NLP Management Units dataset is maintained for the purpose of authoritative reporting on the Australian Government's NRM investments. It is designed to cover all Australian territory where Australian Government funded NRM investments might be delivered.This dataset should not be used to represent legal boundaries (notwithstanding that some boundaries are defined by legislation in some states and territories). It is an administrative dataset developed for the purpose of reporting and public information. Alterations to either the attribution or boundaries of the data may occur in the future, for example to accord with changes to NRM delivery arrangements or to reflect revisions of state/territory regional boundaries.Current VersionThe 2020 version NLP Management Units dataset contains 58 separate mapping objects. These comprise:56 mainland Management Units. A separate object for Lord Howe Island (part of North Coast, NSW Management Unit) A "Marine NRM" Management Unit which combines Australia's Territorial Sea (from 3 nautical miles to 12 nautical miles) and Australia's Exclusive Economic Zone (to 200 nautical miles). It excludes coastal waters (to 3 nautical miles) which are part of the terrestrial NLP Management Units. It also excludes Ashmore & Cartier Islands, Australian Antarctic Territory, Christmas Island, Cocos & Keeling Islands, Macquarie Island, Heard & MacDonald Islands and Norfolk Island, and those parts of Australia's Territorial Sea and Exclusive Economic Zone that surround these locations.The 2020 version was derived from the former NRM regions series (latest version was 2020), originally established in 2006 as the "Natural Heritage Trust II (NHT2) Region Boundaries" dataset. No changes to the spatial alignment of terrestrial region boundaries was made in transitioning from NRM regions to NLP Management Units.The 2020 version updates the previous version (2017) with changes to boundaries of South Australian NRM Regions to align with new regional landscape boundaries (https://data.sa.gov.au/data/dataset/landscapes-sa-boundaries) under the Landscapes South Australia Act 2019 (SA) Act which replaced the Natural Resources Management Act 2004 (SA) Act. Minor edits were made to remove gaps, slivers and overlaps so the new SA boundaries aligned with non-SA NRM Regions. The "Hills and Fleurieu" and "Green Adelaide" Landscapes SA boundaries were merged to form the single 4010 "Adelaide and Mount Lofty Ranges" NRM Region, although at the request of the data owner, the internal boundaries were retained within this NRM region. Additionally a number of gaps and overlaps in the Western Australia NRM regions were fixed.The principle data fields in the 2020 version dataset are:NLP_MU (note this replaces the former NRM_Region field)State (state, territory or 'external' for the Marine NRM unit)Area_Description (eg land area only, state and coastal waters, )NRM_ID (as described below)NRM_ID and NLP_MU names, grouped by state/territory, are as follows:New South Wales (11 Management Units + 1 extra map object for Lord Howe Island)- 1010 Central Tablelands- 1020 Central West- 1030 Greater Sydney- 1040 Hunter- 1050 Murray- 1060 North Coast (excludes Lord Howe Island)- 1061 North Coast - Lord Howe Island- 1070 North West NSW- 1080 Northern Tablelands- 1090 Riverina- 1100 South East NSW- 1110 WesternVictoria (10 Management Units)- 2010 Corangamite- 2020 East Gippsland- 2030 Glenelg Hopkins- 2040 Goulburn Broken- 2050 Mallee- 2060 North Central- 2070 North East- 2080 Port Phillip and Western Port- 2090 West Gippsland- 2100 WimmeraQueensland (15 Management Units)- 3010 Burnett Mary- 3020 Cape York- 3030 Condamine- 3040 Co-operative Management Area (between Cape York and Northern Gulf)- 3050 Desert Channels- 3060 Fitzroy- 3070 Burdekin- 3080 Northern Gulf- 3090 Maranoa Balonne and Border Rivers- 3100 Mackay Whitsunday- 3110 South East Queensland- 3120 South West Queensland- 3130 Southern Gulf- 3140 Wet Tropics- 3150 Torres StraitSouth Australia (8 Management Units)- 4010 Adelaide and Mount Lofty Ranges- 4020 Alinytjara Wilurara- 4030 Eyre Peninsula- 4040 Kangaroo Island- 4050 Northern and Yorke- 4060 South Australian Arid Lands- 4070 South Australian Murray Darling Basin- 4080 South EastWestern Australia (7 Management Units)- 5010 Northern Agricultural Region- 5020 Peel-Harvey Region- 5030 Swan Region- 5040 Rangelands Region- 5050 South Coast Region- 5060 South West Region- 5070 Avon River BasinTasmania (3 Management Units)- 6010 North West NRM Region- 6020 North NRM Region- 6030 South NRM Region- Northern Territory (1 Management Unit)- 7010 Northern TerritoryAustralian Capital Territory (1 Management Unit)- 8010 ACTExternal (1 Management Unit)- 9060 Marine NRMPrevious VersionsThe 2017 version updated the previous version (2016 version 2) with changes to region boundaries in Western Australia and NRM names in Qld, Tas and WA. The 2017 version also removed the NRM_BODY data (added for 2016 version 2) and the non-spatial OceanWatch map label previously included.The 2016 version 2 updated the marine portion of the NRM regions to be consistent with the current (2015) Australian Maritime Boundaries Information System (AMBIS) coastal water limit boundary. It also included a new four digit unique NRM_ID field for sorting purposes.The 2016 version 2 maintained definitions established in the 2015 version, including for the Peel-Harvey NRM region and for the OceanWatch Australia Limited NRM organisation (not spatially defined). It also maintained changes made in earlier versions including: the 2014 changes in NSW from Catchment Management Authorities (CMA) to Local Land Service areas; and the 2012 update/formalisation of the 2010 dataset (which was an interim update of the NRM Regions 2009 dataset, released Feb 2009).The original base layer version of this dataset was released in 2006 as the Natural Heritage Trust II (NHT2) Region Boundaries dataset.Credit:The Management Unit boundaries draw on spatial information from state and territory government agencies data and other sources.
