Grazing project benefits biodiversity and groundwater sources in East Sussex

16th June 2025

South East Water is sponsoring Longbridge Regenerative’ s innovative five-year grazing project using Exmoor ponies to restore 181.3 hectares of grassland, improving biodiversity and safeguarding groundwater quality.

The initiative focuses on managing tor grass, an invasive species that outcompetes the delicate ecosystems of chalk grassland. Exmoor ponies are classed as a rare breed. They are particularly suited to this task, as they naturally graze on coarse vegetation such as tor grass and brambles, allowing chalk grass to thrive.

Chalk grassland is not only a haven for rare wildflowers and insects but has also been identified as one of the most beneficial habitats for maintaining groundwater. By enhancing these landscapes, the project will support local wildlife and contribute to the sustainable management of the region’s water resources.

Duncan Ellis, Farmer and Landowner of Longbridge Regenerative, said: “We’re excited to have piloted the project to and roll it out to other farms in the area.

“Their selective grazing will help to restore the balance of our chalk grasslands, leading to healthier ecosystems and better water quality.

“This project is one of many to leave the environment in a better condition than we found it in.”

Richard Dyer, Biodiversity Manager at South East Water said: “We’re pleased to sponsor the Exmoor ponies as natural land managers in this project.

“This is a fantastic example of how land management and water quality go hand in hand.

“The project will run for five years, during which time the improvements in vegetation diversity and groundwater quality will be monitored.”
