David,
Apparently the drainage attempt which consisted of a series of long =
trenches cut into the sphagnum was carried out in the 1950's. I have no =
knowledge of why the effort didn't work satisfactorily but the land is =
still unsuitable for commercial crops or livestock. As well, I'm not =
sure whether anyone knows what effect the drier state of the bog has on =
the population of G. peckii. It may be a benefit since elsewhere it =
really is an alpine species.
Bob

Hi Bob & All, Sep 3, 2012
I am not familiar with Big Meadow Bog but if it really is a bog =
then that historical drainage attempt almost certainly has nothing to do =
with the drier state of the bog.=20
Bog drainage, with the exception of favorable circumstances, ends =
in failure and in best circumstances usually requires sustained =
Herculean efforts such as well maintained perimeter drains, closely =
spaced tile drains and annual mole drainage.

Subject: [NatureNS] A few days spent on Brier Island
We spent much of the day Thurs helping MTRI staff carry out a census =
of the endangered Mountain Avens (Geum peckii) in Big Meadow Bog. =
Interestingly, Brier is one of only 2 locations for this plant in Canada =
and has by far the largest number of plants. (Digby Neck is the other =
Canadian location and it is also found in the White Mountains in N.H.) =
The bog has been altered in an attempt to drain it for agricultural =
purposes (this is historical) so the bog is drier now=20
