To restore and protect Hertfordshire’s rare chalk rivers and the wildlife they support on a landscape scale.
We have a national and international responsibility for protecting our rare and special chalk rivers, which have a unique ecology due to their clean, mineral-rich water and consistent flows, supporting an abundance of wildlife. A high proportion of the world's global numbers of chalk streams can be found in the South-East of England, specifically in Hertfordshire. (Hertfordshire State of Nature Report, 2020).

Our project will restore chalk rivers and associated wetland habitats across Hertfordshire, halting the decline of over 109 different species including water voles (the UK fastest declining mammal). Our project objectives are to:
Hertfordshire and Middlesex Wildlife Trust (HMWT) has prepared an ambitious programme of capital work and invasive species interventions that will deliver meaningful habitat improvements across the whole river catchment that are ‘ready to go’. These will be delivered by specialist contractors overseen by our project team: Living Rivers Coordinator, Invasive Non-Native Species Officer and Admin Assistant, supported by volunteers. To complement the capital river and habitat restoration works, we will employ a Wilder Communities Officer to engage residents local to our project sites, raising awareness and empowering people to take action themselves to improve species abundance.
Our specific project locations have been selected through consideration of a combination of factors including habitat connections, current condition of wildlife, risk of further deterioration and the opportunity to improve species abundance. Each location contains a Local Wildlife Site (LWS) and we have consulted data reports from Herts Environmental Records Centre (HERC) about the condition of these LWS to help inform our project work – all have declining biodiversity.
We have comprehensive experience in this area, having delivered our Living Rivers Programme for over 12 years. The programme is a core part of delivering our 30 by 30 strategy – where we are aiming to influence at least 30% of land to be wilder and managed for nature by 2030. In the last 12 years of Living Rivers we have:

We have spent years working with over 350 stakeholders to build the necessary relationships to get the river and restoration works in this project ready for delivery. This, combined with our specialist skills and comprehensive experience, means our project will be hugely successful in created wildlife-rich riparian habitats and improving species abundance.
