Likely situations for fence and volunteer pasture

1.     Salinity and waterlogging
This saltland solution is suitable for all saltland that is of low (subsoil ECe 2-4 dS/m), moderate (subsoil ECe 4-8 dS/m), or high salinity (subsoil ECe 8-16 dS/m). That is, any situation where a sown saltland pasture might be considered. At severe salinity levels (subsoil ECe >16 dS/m) and high waterlogging, it is likely that the ‘volunteer’ species will be samphire which is unsuitable for grazing and this solution effectively becomes Saltland Solution 1 – Fence and exclude from grazing.

2.     Climate and soils
There are no specific soil requirements for this solution.

Whole farm economic modelling in SGSL indicated that higher rainfall areas (that predominate in south-eastern Australia) where the volunteer pasture is likely to include perennial species are where ‘fence and volunteer pasture’ is likely to be the best option. In drier areas and more Mediterranean rainfall patterns (that predominate in the wheatbelt of WA), the volunteer pasture tend to be annual species that do not boost out-of-season feed.

3.     Indicator species
There are no indicator species as this saltland solution is applicable across all saltland other than extreme salinity and waterlogging where there are no pasture or grazing options.
