Revegation Practice and Glyphosate

Recently I raised some concerns on fb regarding the current practices used for revegatation work along creek banks in my local area.

Basically, the practice is to use a glyphosate based product to spray the area to be replanted, and perhaps repeat this at intervals.  Once cleared, the young plants used in the revegatation process then have a better chance of becoming established.

What concerned me about this, other than the fact that I believe the use of chemicals in such a way is not a sustainable practice and is in fact somewhat contradictory to the idea behind the revegatation process, was that we may be doing more harm than good.
