Here's the rice-sack planter I mentioned in my post. It's planted with Carex obnupta and Juncus sp. The tree is an Oregon Ash cutting -- my "tree bobber" experiment. I have a bit of video of some baby fish hanging out by the roots shortly after I set it in the creek; they seem to like it. Also, the plants (Carex glauca) in the other pictures were grown in a water treatment tank, the Eco-Reactor at the Oregon Garden, which is circulated with an "air-lift" system. Try looking up John Todd (toddecological?) to find info on that sort of system.
