I know I've sent links to BEST about water hyacinth treatment and usage (e.g., furniture weaving) in Thailand before, but I just ran across this site with pictures of hyacinth treatment areas in the Bangkok area... and couldn't resist sending it out. http://www.fatheroftheland.com/5-c-3.html If the long-standing historical and institutional biases against this exotic plant (which developed for very good reasons) can be overcome, might similarly-styled systems have practical benefit for effective and sustainable treatment of stormwater, wastewater, and badly eutrophied water bodies in Florida?
