Notice the surface of the water?
Of course you don't.
That's because it's covered entirely by a mat of Salvinia minima, a type of water fern.
You can bet there are no submerged plants growing in what must be almost total darkness beneath that cover of Salvinia.
We have a native water fern called Azolla, which is what I thought this was going to be when I first arrived at Haws Creek. I've seen mats of azolla before, but nothing so extensive as this salvinia ... I suppose that may be due to the fact that azolla is a native and therefore has checks and balances on it's population.
Azolla turns out to be a pretty amazing plant, a high protein nitrogen fixer that is an excellent green manure and feed supplement for livestock. The recent rains have filled our ditches and bunched up azolla along the shore where a guy like me can dip some up without even getting his feet wet ... not that I mind that much.
I'm going to go scoop some up and bring it back to my tanks for a little experimentation.
In the meantime, remember ... Salvinia bad, Azolla good.
He supervised me while I was dipping out the Salvinia for the picture.
Oh yeah ... I almost forgot ...
Happy stupid holiday y'all.
