Upcoming Riverfly Partnership Conference

A shallow river with a gravel bed, riffle, and stands of ranuculus takes up most of the picture. A man, to the left, stands in the water and looks down as he collects a kick sample. The river is lined with green leafed trees, the sunshine dappled on the leaves. The Riverfly Partnership logo of an adult mayfly is in the lover left hand corner.

The next national Riverfly Conference is due to take place on the 20th March 2020 at the London Natural History Museum.

The theme is The pressures on our rivers and how we can detect and mitigate them. We are bringing together organisations and individuals from the Partnership to deliver presentations, updates and talks. All are welcome.

'Thames Revival' on BBC Radio

Having been declared biologically dead in 1957, the river Thames has been making a real comeback. As well as porpoises, seals and the odd whale, over 156 species of fish currently live there.

The latest episode of 'Costing the Earth' talks about the monitoring and restoration work that has taken place. We are proud that many of the organisations featured are partners. They discuss the current status of the Thames, and what the future holds.

Image from the BBC website. The episode is presented by Helen Czerski, a physicist from University College London who is co-ordinating a large-scale study of the River Thames. It was produced by Alasdair Cross.

You can listen online here.
