The point being, as I indicated, trees don't necessarily have to line the banks of a desert river or stream.

Yes. Daily max temperatures out here are as I stated.
The max UV is at midday and the temp is within 2 degree centigrade of the max at midday making it the worst time of the day in the desert.

I see, that makes me happy. =)

You have had cold climate fish instead of desert species growing in your desert stream for millions of years? I have to be quite skeptical about that claim and ask for you to provide some evidence to support your statement. Also I do no imagine that you can possibly blame the cows for eating all of the lush vegetation when it's the humans forcing them to live in the desert which is a foreign environment to them.
