This is the best summary I could come up with:

Two large floating platforms covered in 500 native plants have been launched in a city harbour to help improve the water quality.

The two islands, which measure approximately 17m in length, were created at Bristol’s Festival of Nature and are the first of a number of platforms due to be floated in the water this year.

It is part of a £500,000 project to regenerate the Capricorn Quay area of Bristol Harbour.Savita Willmott, CEO of the Natural History Consortium that runs the festival, said the ecosystems were made in response to the “challenges around our waterways”.

"She said above the water the floating islands create a habitat for the likes of pollinators, birds, bats and invertebrates.

Biofilms help to recycle organic matter and contribute to water quality, as well as supplying food for aquatic life.Ms Hebdon said the platforms also “bring back that green space to an intense urban environment”.

Ms Hebdon said over time the platforms would cleanse the water as the plants obtain nutrients from other unwanted plants, such as algae, leading them to die out.The floating platforms have been planted with species including Ragged Robin, Carex Juncus, Water Forget-Me-Not and Irises.Ms Hebdon said they would be treated like usual gardens, requiring weeding and clearing of litter.The islands were made from recycled materials and were fully recyclable, she added.
