This paper describes a wilderness-mapping project that has been undertaken by the Tasmanian Parks and Wildlife Service. Initiated in 2005, the project has so far focussed on the Tasmanian Wilderness World Heritage Area (TWWHA) and adjoining wild areas.

The first phase of the project involved reusing a methodology that was used to assess wilderness values across Tasmania in 1995. The National Wilderness Inventory (NWI) methodology assesses wilderness values as a continuous spectrum based on information relating to geographical features such as roads, walking tracks and logging areas. 

The 2005 analysis reveals both gains and losses in wilderness values relative to the 1995 results. The gains occur primarily in areas where vehicle tracks have been closed or huts have been removed. The losses are primarily due to track and infrastructure development, such as the tourism development at Heritage Landing. 

The second phase of the project involved developing a revised methodology to correct some deficiencies in the NWI approach, mainly by taking terrain and vegetation into account when calculating access-remoteness. The revised methodology gives a broadly similar assessment of wilderness values overall, but it gives different weighting to some features and it highlights the wilderness impact of mechanised boat access on the West Coast. 

The Parks and Wildlife Service also proposed developing a methodology to assess the impact of viewfield disturbances on wilderness values. If developed, this should be incorporated into the wilderness-assessment methodology, and the wilderness values of the TWWHA reassessed. The wilderness-assessment program could also be expanded to take in other regions of Tasmania.
