Nick,
I am not aware of any ot these places being wooded then and =
subsequently converted to agriculture. I do recall collecting in =
hardwoods on Salmon ancient floodplains, well above 50s flood levels, =
soon to be stripped for gravel; not agriculture.
Meadows which frequently flood in summer and are nearly always =
flooded over winter don't support trees.

you guys back in the EC Smith days covered the province...

Hi Nick,
Where were floodplains converted to agriculture in NS ? A =
smattering in NB but none is NS that I am aware of. Some Salmon River =
floodplains were mined for gravel when the 100 series highways were =
built near there and I think some floodplains near Oxford were mined.=20
Floodplains are enriched by the silt deposited by floodwaters =
each year; e.g. Nile, Tigrus not by trees which may take advantage of =
the enriched soil.

Hey John
yes tree roots are purported to be amazing N and P pumps and can =
take up nutrients before they reach waterways..90% range according to =
Maltby who was working on big rivers of Europe.
when you lose trees you lose these pumps and go to lower =
functional states and herbaceous plants arent a lick on trees.
The tree was an engineer of floodplains in big ways and we lost a =
lot of that when we converted floodplain for agriculture. This =
floodplain forest is what supports a good group of the Appalachian =
Deciduous Forest species..bloodroot, blue cohosh Canada violet (?) wild =
coffee, Canada Lily, wild garlic, yellow violets, toothwort, Solomon's =
plume..and this is the habitat we need right now to let us preserve the =
diversity that is expanding northward and may be eliminated from =
Kentucky in time. I'm looking forward to being able to eat pawpaws, =
crush spicebush leaves and swing on forest grape vines in my nineties in =
Nova Scotia but first we need to secure and restore floodplain habitat.
must be midwinter=20

Hi John & All,
Any deep-rooted plant will move nutrients to the surface if =
that is what you mean. Grasses are in general better than trees because =
their fine roots can penetrate the pores of rigid soils not accessible =
to tree roots. This is why Agropyron repens (Couch) is such a vigorous =
weed. And why the fertility of Prairie soil is immense.

Trees have been called environmental engineers as they make =
habitat and set up the food web. We are very lucky to have neighbours =
that let us walk and bring kids through their woods that are in good =
condition with large mature trees of pines and hemlock. We saw the =
strips of tree felling from the microbursts that we called the Berwick =
Blow of a few winters ago that took out some 200 year old hemlock but we =
also see blow down along a line between two properties where still =
another neighbour has clearcut and it has made it not possible to ski in =
the adjacent uncut property over a 40m width due to blow down.=20

Hi Dusan,
Yes and no. A sufficiently high wind can mow a swath =
through undisturbed forest. And counting Dec 13, 2010 (ignoring Juan =

May, 2013 (?). And many winds which finish the job or start fresh ones.
