Let's not get carried away here...

Research also shows that tamarisks tend to become established after the stable drainage system around a river has already been changed, for example by increased upstream abstraction. (So it may well be the tamarisk arrived as a result of the reduced low in the Coloradao!) Another study shows that saltcedar is 'functionally equivalent' to native cottonwood and that in saltcedar 'understory herbaceous cover and species richness were significantly greater than in cottonwood stands'. (Email me offlist for references.) So what happens to the unusually rich herbaceous flora when the saltcedar is sprayed (as recommended in the South West farm Press article)?

I had no idea this would become such a popular item.
Here's a link to the origin of the stats I quoted earlier. It's a pub in New
Mexico (No, not THAT kind of pub. An Ag paper.)

I first met tamarisks up close & personal in Arizona in 2001, on a raft trip
through Grand Canyon. Trees 20 feet and more from the river's usual bank have
roots that stretch right into the water. I believe they are probably a major
contributor to the fact that the Colorado doesn't make it all the way to the
ocean anymore. And yes, at a couple thou per acre, they would be pretty shrubby.
