Cutting Cutting (Marsh Master):
- Versatile, can reach most areas of
the Crown Marsh
- Cuts phrag of all life stages
- Ice may cause damage to the Marsh
Master and therefore timing window for use may be limited some years
- Scatters the biomass and allows light
to penetrate ground surface or water
- Fire would only an option in dryer
areas and even then may not readily carry fire – no removal of biomass and seed heads
- For this specific project – cost per
hectare was approximately half compared to rolling

Rolling Rolling (Centaurs/Argos with rollers):
- Limited access, 30 cm of water is
the max limit for the equipment – machinery is prone to getting stuck past that
- Young and spry phrag stems do
not roll well in warm/wet conditions
- Effectiveness is dependent on
deep freeze conditions
- When ideal conditions are met,
rolling creates a thick mat of phrag which readily carries a fire
- Resources for rolling are currently
more readily available and when ideal conditions are met the job can be done quite quickly (ideal for working within a burn window)
