What I found was elevated TDS (a specific _amount_ of conductivity, I
suppose) in former flame chub streams compared to current streams, 140 ppm
to 120 ppm respectively. That would be consistent with elevated runoffs from
point or nonpoint sources. You're talking about the Tennessee Barrens,
right? That area has suffered pollution from a peculiar source, and this
pollution shows up in springs via groudwater. The pollution source is
numerous tree farms, that raise trees to be sold during National Arbor Day.
To raise the trees they of course clear land for monoculture, and also apply
various herbicides, pesticides and fertilizers which quickly are mobilized
in rainwater and wind up in groundwater, coming out-in-springs. This has had
a bad effect on the few remaining wild populations of Fundulus julisia, the
Barrens Topminnow, whose spring habitat is degraded by this eutrophication.
So there's the joke -- well-meaning people buy small trees to plant for
Arbor Day, but the plantation culture producing many of these trees is a
major force in local habitat degradation. That makes me glad that trees
reseed themselves on my property. . .
