Summary of the Wyre Natural Flood Management Project
The Wyre Catchment Natural Flood Management Project (Wyre NFM project) is the first example in the UK of farmers being paid to deliver natural flood management (NFM) as part of a commercial agreement. The project plans to deliver more than 1,000 targeted measures to store, slow and intercept flood water and prevent peak flow in a catchment in England. These interventions, such as leaky dams, hedgerows, ponds and scrapes, will be hosted by farmers for an annual hosting and maintenance fee over the next nine years, with an option to extend the project to up to 50 years. As of November 2023, the project has started to install these interventions on the lands of the farmers who initially signed up, and further farmers are being onboarded.

Key Takeaways
- The modelling team built a hydrological model that captured feedback and considerations from the farmers on what NFM interventions would work best on their land.
- From this, 70 hectares of interventions were agreed with the farmers, including 39 hectares of woodland planting, 10km of hedgerows, 42 ponds and scrapes and 1710 leaky dams.
- The NFM interventions, such as woodland planting, hedgerows and leaky dams, will be installed by the Wyre Rivers Trust over three years. The farmers face no installation costs.
- Once installed, the farmers will be responsible for the day-to-day maintenance of the interventions.
How did the farmers participate in the modelling of the flood risk reduction?
The project needed to show that a 15% reduction in peak flow during severe storms (an agreed proxy measure for flood risk) would be possible from NFM interventions installed across the catchment.
While the initial hydrological model (see Milestone 1) showed what NFM interventions would be most effective where, a lot more work was needed to quantify the impact of these with enough confidence to base a commercial agreement on.
The project team – including the Rivers Trust, Wyre Rivers Trust, FloodRe, United Utilities and the Environment Agency – pooled all their relevant data to build this more detailed model. They also hired JBA Consulting, which had extensive experience with NFM modelling.
By this stage, the 10-15 farmers that were interested in the project had fed in their thoughts through the ground-truthing phase, where the Wyre Rivers Trust
The farmers contributed to this modelling by providing local knowledge and honest feedback on what they thought was likely to work best.
The benefits of the NFM interventions were modelled over nine- , 20-, and 50- year time horizons, in line with the commercial timeframes that had been agreed with the farmers, buyers, and investors. The model included predicted changes in flooding frequency and intensity from the impacts of climate change. The modelling process took around one year to complete, though the project team highlights that this process was the first of its kind.
What interventions were decided on, and how are these being installed on the farmers’ lands?
As a final result, and alongside negotiations with the farmers, buyers, investors and other project stakeholders, the NFM interventions were agreed across 70 hectares in the catchment. These interventions include:
- 39 hectares of woodland creation
- 1710 leaky dams
- 42 ponds and scrapes
- 10km of new hedgerows
The farmers are not paying for any of the capital works, which is covered by the upfront investment that the project team secured, which will be repaid with the buyers’ payments and a grant from the Woodland Trust for the woodland creation.
The Wyre Rivers Trust is installing these interventions on the farmers’ lands over three years (up to 2025). This three-year timeframe is driven by a number of factors including; delivery capacity, seasonal timings for installing these interventions (such as tree planting) and the staggered signing of the agreements with the farmers. When the project was launched in April 2022, five or so farmers had signed their contracts with the remaining farmers finalising negotiations with the project team over the next 18 months (see Milestone 8 for more detail on this).
What are the farmers responsible for across the lifetime of the interventions?
The farmers will be responsible for day-to-day maintenance of the interventions. The maintenance plan was developed mainly between the farmers and the Wyre Rivers Trust, which has extensive knowledge of how these interventions are best maintained, and the associated costs.
Turner comments that the farmers were happy to accept the responsibility of maintenance as this would take minimal time and cost. However, they highlighted the need for a clear maintenance standard and clarification of what ‘day-to-day’ maintenance involves, as opposed to heavier maintenance activity. To address this, the Wyre Rivers Trust developed a maintenance manual for the farmers to use. Heavier maintenance activities, such as the replacement of fences, will be undertaken by the Wyre Rivers Trust when the farmers report the need.
The farmers are also responsible for the costs of maintenance, though these costs are built into the annual payment figures that are agreed with each farmer.
The farmers are not responsible for any formal monitoring or reporting on the interventions, which is undertaken by the Wyre Rivers Trust.
This monitoring will also feed into a five-year ‘adaptive management phase’ that will try and optimise the performance of the interventions before buyer payments increase significantly in Year Six (to cover cost of repaying the up-front investors). The Wyre Rivers Trust will work with the farmers for any relevant changes from this to the management of the interventions.
