    IN my concluding comments to this ACIAR workshop on the productive use of saline land I want to make a few comments regarding: (a) the size of the salinity problem in Pakistan; (b) the process of goal setting; and (c) some critical factors limiting revegetation

    Predictions of watertable depth and soil salinity levels for land capability assessment using site indicator species

    Salt-affected land varies spatially and seasonally in terms of soil salinity and depth to the watertable. This paper asks whether native and naturalised species growing on saltland can be used as ā€˜indicatorsā€™ of saltland capability. The percentage cover of native and naturalised species was recorded in spring 2004 and 2005 across saltland transects on three sites in Western Australia. The presence of these plants was related to average soil salinity (ECe) at depth (25ā€“50 cm), and depth to the watertable in spring. Eight naturalised species occurred with ā‰„40% cover on the sites. Species preferences varied, with some such as samphire (Tecticornia pergranulata) and puccinellia (Puccinellia ciliata) only occurring with shallow watertables (16 dS/m. Other species such as capeweed (Arctotheca calendula) and annual ryegrass (Lolium rigidum) were dominant where watertables were deeper (>1.3 m) and salinity levels lower (ECe values 2ā€“8 and 4ā€“16 dS/m, respectively). Our data suggest that some of the species recorded can be used as indicators of saltland capability and, further, can predict the most productive species to sow in that area. Other species were found not to be good indicators as they displayed more opportunistic habitat requirements

    Using saltland in Pakistan : an Australian connection

    Get PDF
    Pakistan and Australia have a common enemy in salt. In each country millions of hectares of previously productive land have been affected by salt (or have the potential to become saline) because of inappropriate agricultural development. Since 1989 the Western Australian Department of Agriculture has participated in a research project in Pakistan which involves revegetation of salt land using Australian shrubs. Early results are very promising
