This layer is the result of a wilderness mapping project that was undertaken by the Parks and Wildlife Service (PWS) in 2005. The scope of the project was the Tasmanian Wilderness World Heritage Area (TWWHA) and some adjoining areas considered to be of high conservation area. The project driver was to fulfill a requirement of the 1999 TWWHA Management Plan (p94); "Develop an enhanced methodology for the quantification of wilderness which more accurately reflects the Tasmanian situation eg. incorporates the effect of the three dimensional nature of the terrain on viewfields and deals systematically with the effects of walkers' huts and walking tracks". The methodology followed the guidelines of the National Wilderness Inventory (NWI) which was developed by the Australian Heritage Commission in the late 1980s and early 1990s to identify wilderness quality across Australia. The methodology is described in detail in the NWI Handbook of Procedures, Content and Usage (Lesslie and Taylor 1995). See hyperlink below for notes on the NWI from the Australian Heritage Commission website. The plan notes (p92) that this is likely to involve the implementation of a modified version of the NWI methodology. However, it does not restrict the PWS to the use of this methodology. The objective of the first phase of the project (Module 1) was to use the existing NWI methodology to assess wilderness values in the WHA and in specified adjacent areas, based on the latest available information on roads, walkers, huts and similar infrastructure. In the second phase (Module 2), wilderness was to be assessed using revised criteria taking into account walkers' huts, tracks and time-remoteness. The assessment of viewfields has been postponed to a future study. The business processes, input data, spatial analysis and results are described in the project methodology document, available in the hyperlink below. The wilderness quality layer is a coverage that represents the level of naturalness and remoteness based on the proximity of physical intrusions and infrastructure. The study did not consider social aspects.

This layer is the result of a wilderness mapping project that was undertaken by the Parks and Wildlife Service (PWS) in 2015. The scope of the project was the Tasmanian Wilderness World Heritage Area (TWWHA) and some adjoining areas considered to be of high conservation area. The project driver was to encapsulate the level of wilderness quality of additional areas added to the TWWHA in 2013. A rerun of the previous 2005 assessment, for the TWWHA (at the 1999 boundary) allowed the project to see what changes in wilderness quality had occurred between 2005 and 2015 for existing areas of the TWWHA. The methodology utilized was the same as the wilderness quality study of 2005, see metadata on WHA Wilderness Quality 2005 (PWS), which was also based on the Commonwealth NWI (below). The methodology followed the guidelines of the National Wilderness Inventory (NWI) which was developed by the Australian Heritage Commission in the late 1980s and early 1990s to identify wilderness quality across Australia. The methodology is described in detail in the NWI Handbook of Procedures, Content and Usage (Lesslie and Taylor 1995).

The depiction of zoning as defined in a statutory reserve management plan that has been declared under the National Parks and Reserves Management Act 2002 where PWS is the managing authority. Does not include zoning from the Tasmanian Wilderness World Heritage Area (TWWWHA). A core function of a management plan is to establish zoning, in order to guide use and development. The integrity of the zone descriptors from the management plan are retained, with legend classes matching current zoning descriptors from the PWS Reserve Management Zoning Policy. Three types of zoning exist in this layer. Statutory zoning as defined in the management plan, draft zoning for a management plan in development and prescriptive zoning where additions to a reserve post-date the management plan. Attached are the business rules that have been adopted for the depiction of the zoning. Statutory zoning closely matches the zone descriptors in the management plan. Prescriptive and draft zoning adheres to the business rules adopted for the creation of the General Plan Reserves Zones with input from professional staff. Links to the business rules and policy documents can be found below. This also includes descriptions and intent of the zone categories.

The location of disturbed sites designated for restoration or rehabilitation back to a natural state as depicted in the PWS Asset Management System (AMS). Features are on reserved and crown land.

The location of significant weed occurrences identified for priority management or monitoring as depicted in the PWS Asset Management System (AMS) and considered an environmental threat. The majority of weeds also have a status of "declared" under the Tasmanian Weed Management Act 1999. Weed locations are on reserved and crown land. Weeds have also been captured on some private properties that are adjacent to the Tasmanian Wilderness World Heritage Area (TWWHA) and were party to the TWWHA Neighborhood Program (2016). These weeds are considered a potential environmental threat to the TWWHA if they spread. The on-going treatment or monitoring of weeds is recorded using a grid transect over affected areas. This treatment information is stored in another layer, Weed Control (PWS).

The World Heritage Area dataset was created to map priority vegetation in the Tasmanian World Heritage Area. The coverage extends across the entire World Heritage Area. Polygon data was taken from aerial photograph interpretation and field checking. Combinations of understorey and canopy species are mapped, including mosaics between communities. Classification is based on structure and floristics. It is a stand alone dataset.

The location of reserves and crown land as depicted in the PWS Asset Management System (AMS) where PWS or PWS (Crown) is the managing authority. Reserves classes include conservation area, game reserve, state reserve, nature reserve, historic site, national park, nature recreation area and regional reserve. Crown land includes future potential production forest land and some unallocated crown land parcels and public reserves.
