Summary
This report describes the work carried out to quantify the extent and impacts of dryland salinity in Tasmania for the National Land and Water Resource Audit.
In 1993, with less than one percent of the total agricultural land considered to be salt affected, soil salinity in the State was considered to be a relatively small problem compared with mainland States such as Victoria and Western Australia.
Expressing the saline area as a percentage of the total masks the concentration of salinity in certain districts, which is acknowledged to varying degrees.
The purpose of the National Audit is to provide an objective assessment of dryland salinity at the regional level by using a consistent analytical approach.
This assessment will be useful for making more informed decisions, not only in the context of policy at all levels but also in the context of land management.
Given the district nature of salinity distribution in Tasmania, the emphasis has been on reporting by land systems containing salinity which can be related in particular to Local Government Authority boundaries, as well as catchments.
These Authorities have a key responsibility for service delivery in contexts affected by the salinity issue, such as catchment management and the planning process as well as road maintenance and reticulated water supplies.
The extent of dryland salinity is shown in this Report to be a small problem relative to some Mainland States but that it is an increasing problem.
It is acknowledged that "prevention is better than cure" regarding salinity and so the Recommendations in this Report have been framed with this in mind.
