Level of confidence in fence and exclude from grazing

1.         Farmer experiences
There are no recorded case studies that track the progress and benefits from fencing off saltland and excluding grazing.

2.         Research
This saltland solution has had little systematic research, at least partly because there is no chance of any financial return on an investment in this solution and therefore no ‘commercial’ investors. 

In the 1960s, Clive Malcolm studied the effects of temperature, salinity and seed scarification on samphire germination, but as its nutritional ‘qualities’ have become better understood, the possibility of grazing has been discarded. 

3.         Risks and challenges
As this is a ‘let it naturally revegetate’ solution, there are few risks or challenges.  Preventing grazing will result in revegetation in all but the most extreme salinity situations, and it matters little what grows, as long as it provides groundcover and better amenity than bare saltland.

4.         Future prospects
There are considerable areas of saline land in Australia (some estimates suggest half of all saline land) for which this is the recommended solution.  As such, it has significant ‘prospects’ as an on-going solution for the most severely salinised and waterlogged parts of the landscape.

The prospects of research developing commercial options for this land class are slim and will attract little if any investment.
