1. Floating wetlands, can you help me in getting some online free software for design Alex?

2. What do you see as the pros and cons of each, and their applicability to which ecosystems?

3. My favourite wetland is the one that works, it is never a simple 'lets put one in place' but to decide which sort or combination of two or more systems.
