First-of-a-kind pop-up brings wetland to the inner city

By Ursula Billington  Thursday Jun 5, 2025

The Festival of Nature’s Wild Weekend is staying true to its name with the creation of an urban wetland that will bring the sights, sounds and smells of this vital watery habitat to Millennium Square.

The sensory installation harks back to the city’s pre-paved environment of 200 years ago when areas in the centre were marshland, fed by the Rivers Avon and Frome.

Created by the Wildfowl and Wetlands Trust (WWT), the eight-by-eight metre immersive experience will include reeds, sounds and sculptures evoking wetland wildlife like warblers, water voles and kingfishers.

Wetlands are one of the world’s most important ecosystems, being among the most biodiverse, and with 40 per cent of plants and animals dependent on them as well as the livelihoods of one billion people and the food security of half the world’s population.

They are also under threat worldwide: the UK has lost over 75 per cent of its inland wetlands in the last 300 years, significantly reducing the natural environment’s capacity to support wildlife, filter water, store carbon and prevent flooding.

Concreting over marshy areas, such as with Canons Marsh, Queen Square and the Redcliffe areas around Millennium Square, increases the city’s risk of flooding as well as removing natural capacity to lock-in carbon and environmental ways to mitigate extreme weather like heatwaves.

Watery habitats in general are critical for supporting wildlife as they move through the landscape. Even small examples such as balcony ponds and bird baths can make a dramatic difference to environmental health.

The Festival of Nature is celebrating water in its 22nd edition which runs from June 7-15.

A programme of over 80 activities and the Wild Weekend, which last year attracted 15,000 visitors, will teach participants why water is so essential for nature and how to facilitate and celebrate it.

The 1001 Homes for Nature campaign encourages festival visitors to get involved in creating their own water habitats and nature solutions at home. The Millennium Square wetland will be open to experience over June 14 and 15.
