The Guardian reports on the Wildfowl & Wetlands Trust's five-year, Aviva-funded £8.9m drive to make Bristol the UK's first "wetland city", starting with floating wetlands installed in the city-centre harbour that already draw dragonflies and other wildlife. The trust hopes Bristol will win Ramsar accreditation, with more than 200 projects planned to restore wetlands, cut flood risk, and open green and blue spaces to urban residents.
