On minerals and salts for animals: Yes, they provide a salt lick. But nothing fancy. And they have never encountered the selenium void issue. So I made them aware of it.
Salobon,
That is a topic he has covered many times. In fact, he has some special pond designs that are for rainwater only in dry areas. And he has brought lakes to a desert in spain that is rainwater only.
But, most of his work is with tiny dribbles of water like he has at his place in the alps.
