The US govt introduced tamarask into the Colorado River to control soil erosion. It now chokes the banks all the way from the Gulf of America to its headwaters in Montana. It sucks up vast amounts of water. River beaches we used to use became jungles and we needed machetes to get through. They’ve tried burning it out to no avail. Now they are using a beetle to control it. God only knows what problems the beetles are going to cause.
Morons.
I must have missed when they rerouted the Colorado to flow into the Gulf of America. You’re right about the tamarisk, though, or salt cedar as it’s known here.
Typical results of “experts” who quite often have their asse* (of course using Taxpayers’ money).
