Hi Andy & All, June 29, 2012
Elephant grass is a vague term sometimes meaning 'true' African =
Elephant Grass, Miscanthus, Phragmites or another grass. So the Florida =
experience likely refers to some other grass.=20
Miscanthus gigentaeus is reputed to not set viable seeds and =
accordingly can not spread rapidly. It apparently has been used to =
generate electricity in the UK for many years. Fields typically remain =
productive for 20 years, so the carbon cost of digging and planting =
rhizomes is relatively low per year, and apart from carbon associated =
with harvesting and transportation, it is a carbon-neutral source of =
energy. It is harvested in spring, well after mineral nutrients have =
leached from the culms, so it requires no fertilization and rhizome/root =
activity improves soil.=20
Based on experience with two small patches of Phragmites, I would =
expect the perimeters of Miscanthus plantings that are adjacent to =
woodland to quickly become thickets of 'invasive' native tree species. =
But annual mowing should keep these shrubs in mowable condition.=20
The project sounds like a very good idea except for the suggestion =
that the proponent will have a monopoly and effectively have control of =
the land for the term of an agreement. There must be some key player so =
the power plant has an assured sufficient supply but I would prefer to =
see production open to anyone and perhaps it will be.
Several years ago some company in Pictou County was preparing to use =
a perennial grass for fuel and I wrote to them asking if they had =
considered Phragmites but received no reply and don't know if their =
proposal became a going concern or not. I now see that Miscanthus is far =
more productive than Phragmites.

Subject: [NatureNS] elephant grass
There have been a couple of articles in the paper lately about a =
proposal to grow and burn elephant grass, Miscanthus giganteus, to =
generate electricity. The proponent says there is lots of abandon =
agricultural land in Nova Scotia that would be suitable for this crop. =
They say elephant grass is not an invasive species. However, I read =
something about it being very invasive in Florida, taking over =
waterways. Maybe it's another grass called elephant grass.
Does anyone know about this plant as a crop for harvesting in Nova =
Scotia? I'd be curious to see some reputable sources on whether this is =
a good plan, or not.
Thanks
Andy in Freeport
