Volunteers help the South East Rivers Trust clear vegetation

New funding to help communities reconnect with rare chalk streams

The South East Rivers Trust has received support from The National Lottery Heritage Fund to begin an exciting new project helping communities reconnect with some of the UK’s rarest rivers.

The South East Rivers Trust has received support from The National Lottery Heritage Fund to begin an exciting new project helping communities reconnect with some of the UK’s rarest rivers.

Made possible thanks to National Lottery players, the Chalk Stream Connectors project will focus on four chalk streams flowing through South London and the surrounding area — the WandleCrayDarent and Hogsmill.

Bringing rare rivers closer to communities

Chalk streams are among the rarest habitats on Earth, with around 85% found in England. These unique rivers are known for their clear waters, rich wildlife and cultural importance.

Yet despite flowing through local neighbourhoods, many people feel disconnected from them.

Chalk Stream Connectors is about changing that — helping more people access, enjoy and feel a sense of belonging to their local river.

Listening, learning and working together

During the development phase, running until March 2027, we’ll work closely with communities to understand what helps — and what can be a barrier — to accessing these rivers.

We’re particularly keen to hear from people who are often underrepresented in green spaces, including:

  • Older people
  • Young people
  • Carers
  • People with disabilities or health conditions
  • People from minoritised ethnic backgrounds

By listening to lived experiences, we can shape a project that truly reflects what communities want and need.

Activities happening across the rivers

Over the coming months, we’ll be out in communities along the Wandle, Cray, Darent and Hogsmill, delivering a range of activities designed to bring people closer to their rivers.

This will include:

  • Community events and river walks
  • Environmental education sessions with schools
  • Microgrants to support community-led activities
  • Collaboration with local organisations and partners

These activities will help build stronger connections between people and their local natural spaces.

Shaping the future of chalk streams

This development phase is the first step in a longer journey.

What we learn will inform a future funding application to The National Lottery Heritage Fund, with the aim of delivering practical improvements that make these rivers more accessible, inclusive and welcoming for everyone.

Get involved

We’d love to hear from you — whether you have ideas, experiences to share, or would like to take part in upcoming activities.

Funded by National Lottery players

This project is made possible thanks to funding from The National Lottery Heritage Fund.

By connecting more people with these rare and valuable environments, we can help ensure chalk streams are understood, valued and cared for — now and in the future.
