Big Chalk: the Hamble Brook project

Big Chalk: the Hamble Brook project

We’re delighted that our Hamble Brook river restoration project is now featured as a case study by the Big Chalk Partership. The partnership is forging vital connections between nature recovery projects across the chalk and limestone landscapes of southern England. The Big Chalk Partnership brings together more than 150 organisations, each of which is developing and delivering successful projects that will help achieve a shared vision of nature-rich chalk and limestone landscapes that benefit all of us.

Between 2022 – 2024 the Chilterns Chalk Streams Project  worked with local partners to restore 1.1km of the stream – that’s 16% of the entire length of the Brook, making this one of the largest winterbourne restoration projects ever attempted. 2500m2 of wetland was created and sixty native saplings were planted to improve shading and provide natural temperature control. The Hamble Brook project was completed by the CCSP team with the support of the Environment Agency, National Trust, R.J. Bull Ltd, and local landowners.
