Interview by Josh King of David Reed on July 21, 2009. 

Josh:   Okay,
David Reed, uhm, PhD student of Atmospheric Sciences, July 21, 2009, is
going to talk about his research and the bark beetle.  Just general

David:  Yeah so, uhm, it's a eco-variant site which we just
saw, it really is, uhm, a tower based instrument way of kind of looking at
ecosystem levels, uh, processes, uhm, so what that site is doing in in bark
beetle infestation, as the trees are dying, uhm, you know, its going to
have an affect on the ecosystem.  So, from both the tower scale that kind
of the ground scale, too, we want to understand what's happening in the
ecosystem.  As the trees are dying, uhm, various bacteria in the soil is
decomposing and then hopefully it runs long enough, hopefully I'll be gone
before then, but as the site regrows, uhm, and comes back, more trees are
coming back in.  So its, hopefully it's going to be a long term site.  Uhm,
I, I was the one who set up all the tower based stuff, uh, this last
winter, so its been running for about a year now or a full growing season. 
Uhm, what else.

Josh:  Is it starting to produce..

David:  What's

Josh:  Is it producing results that you can analyze?

David:  Yeah,
yeah, it is, uhm, especially, so, yeah so that there's the tower which kind
of sees the whole ecosystem, uhm, and then from the ground we have ten
different trees that are we're monitoring how much water is going through
them, and uhm, we we installed sensors in five, at the time, live trees and
five dead trees.  Uhm, it, it's really clear from the individual trees
point of view which ones are dead because they're not really moving water
anymore, uhm, which ones are still alive and then which ones have been hit
this year.  Uhm, so the individual trees see it, uhm, it, it, it's starting
to see positi.., it is starting to see the effects at the ground too, where
you have, you know the dead needles falling down uhm, and that's going to
change the fluxes of of gas coming off the soil.  Uhm, and it should be be
seen too from the tower but I haven't really gotten the chance to really
look at that yet.  Uhm, because, again, the tower kind of sees everything
happening at once uhm, so that's I guess the last thing to see because if
one tree dies, uhm, that tree sees it but then the whole ecosystem isn't
going to really see just one tree that dies.  Uhm, so, yeah, to answer your
question, yes, we are starting to see significant effects of, of, of as the
trees are dying uh, in the carbon, water and also nitrogen budgets in the
ecosystem.  Okay.

Josh:  Okay, anything else you want to add

David:  Uhm,
I don't know what it would be

Josh:  Okay
