Habitat Creation with Long-Term Ecological Value
Chalksole Farm is being transformed from land previously used for grazing and intensive arable farming into a managed habitat bank designed to deliver long-term biodiversity improvements.
The project includes new broadleaved woodland, mixed scrub, species-rich hedgerows, priority habitat ponds, individual trees and extensive areas of neutral and calcareous grassland. Together, these habitats will create better feeding, nesting and movement opportunities for wildlife across the site.
New woodland and hedgerow corridors will also help connect existing habitats, including nearby Sites of Special Scientific Interest. This creates safer routes for wildlife and supports species such as dormice, which depend on mature woodland edges and species-rich hedgerows.

Chalksole Farm
Chalksole Farm is located within the North Kent Downs Landscape Character Area, part of the Kent Downs National Landscape.
The land was historically used for dairy and arable farming. It is now being managed as a long-term habitat bank, with new grassland, woodland, scrub, ponds, hedgerows and trees being created across the site.
The farm sits alongside established woodland habitat, helping the project strengthen ecological connections across the wider area.
