Yes, that's the one.
I don't know for what reason, but just going to that reed canary grass, do we know whether by removing it we are damaging or doing something to other species? Have you been told that it is an invasive species? Is it a native species or is it something that you know...? You said that it would restore the water to clean, but do we know that it doesn't harbour other ecosystems? I'd like to hear your thoughts on that.
