Mark - I've been very interested in this topic, but for slightly different reasons: I had a bottle attached to a weighted string that was marking a spot in our lake and was amazed by the number of small bass (8"-12") and minnows that would hang around that small object - just imagine what would happen around a floating wetland/island! I previously did a lot of searching on the net to try to find a way that I could build one that would last and not be an eyesore without spending much money. The ones like what was in the link above are quite expensive. I would love to hear other folks thoughts on how one could be made on a budget and also what plants would make good plants (I don't want to plant something that could spread seeds to other parts of the shore and become issues). I personally would like to plant some lilies on a floating island, but I'm not sure what kind would not spread and cause issues. One idea for floating islands that I have considered is using black milk crates bonded together - I think that they would support the weight of the plants esp with extra floats added around the structure. I was thinking that they could be placed in the water so that the plants could be placed inside of them. Any plants that I use would need to be "turtle proof" so that they would not all be eaten up.
