A clearer picture of the changing patterns of salt distribution in irrigated soils is being sought through an undergraduate study funded by the National Program for Sustainable Irrigation.
The Australian Biodiversity Salt Sensitivity Database contains information on the sensitivity and tolerance of over 1200 species of Australian taxa to salt. The database is supported by interpretive notes and a statistical analysis of species groupings
The key element of this project involves the landscape-scale (1,500 ha) manipulation of water regimes on Dowd Morass in the Gippsland Lakes. Dowd Morass is subject to an inappropriate water regime, having been flooded more-or-less permanently since the mid 1970s despite it having probably experienced annual draw down and a dry period every 2-5 years under natural conditions in earlier times before river regulation and catchment development. It is subject also to chronic salinisation from saline (more)...

Born and bred in Renmark, Jack Seekamp has worked a fruit block, run a company and lectured at University all the while making notes, taking photographs and keeping an eye on the Murray.
As long ago as the 1940’s he raised concerns about salt levels, then in 1967, he produced a landmark home video ‘Salt in the Murray Valley’.
Jack’s vast records have been described as ‘virtual goldmine for environmental scientists’ which is ‘priceless (more)...
