Restoring Our Chalk Streams

Katie talking about chalk streams

Chalk streams are one of the most important water features in this area. They are a globally rare habitat in Northwest Europe and an important habitat to the UK – our equivalent of rainforests. They are hugely important for supporting biodiversity, as they support a wide range of flora and fauna including freshwater sponges, brown trout, and mayflies.

So it was a real pleasure to work on a restoration project for Cherry Hinton Brook, along with Ruth Hawksley of the Wildlife Trust, Cambridge City Council, Friends of Cherry Hinton Brook and other environmental activists.

We met at the Daws Lane bridge to reshape the bank and improve the flow of water by restricting the brook in some areas, returning it to the state it was in before the area was developed.

In 2019 I convened a forum on the water crisis facing the region (you can read our full report here on my website), and we highlighted the importance of the chalk streams, so it was great to get my hands dirty – and my feet wet – helping improve them.

The work was covered by BBC Look East and you can see the report here
