After several years of a reprieve from curly-leafed pondweed in my smb/yp pond, it appears to be coming back with a vengeance. I thought that the papershell crayfish had it under control, but with so few submerged plants over the last few years, perhaps the smb knocked them way back? Hopefully, the crayfish population will build back up and a balance will be reached, rather than boom-and-bust cycles.
