dam-l Re: help me please!
I don't have time to read whatever is in this note
but have forwarded you the information sent to me
from our forestry working group coordinator in
response to your query as well as this message you have sent to me.
His name is Michael Buckthought. he has extensive experience
in forestry and ecological issues.
He is NOT with Grizzly Hydrological. He is
with the Ontario- PUblic Interest Group of
Carleton University.
Should I get any responses from either of the other environmental
specialists I sent I will fwd them to you.
It occured to me about an hour after my last repsonse to you that one thing - again - this is BASIC ecology - Intro to Eco 101 type stuff...
any water system, riverine or lacustrine casues the surrounding veg. to
be an biome lower because of moderating microclimatic effects on the areas
immediately surrounded by the water system.
In point of fact reservoirs frequently *destroy* trees by submergence,
as well as other types of vegetation, [forest] litter, etc resulting
in the release of greenhouse gases due to decomposition of dead flooded
biota.
Back to microclimate moderation by a river system:
An eg.
in the arctic, veg along river edges - whether or not they are
impounded [- impoundment does not RESULT in trees magically sprouting
consider -> why would it?!] is subarctic. Likewise spp of vegetation
found in one system to the south can be found along river banks -
temperate spp of trees and ericacious shrubs etc can be found along
subarctic [boreal] ecozones.
Is this the case for reservoirs?
I rather doubt it becasue of drawdown. Awhh.. go look it up. :-)
Well with any luck you've gotten a good book out of tyhe library by now.
that's where scientists get much of their information. Not from
the web.
The net isn't going to replace libraries and good search techniques.
cheers!
