South Downs plants wildflower network to save bees
A 100-hectare wildflower corridor is being planted across Hampshire and Sussex to reverse the decline of pollinators. The South Downs National Park’s Bee Lines scheme connects fragmented habitats, with early signs of bees and butterflies returning.
More than 100 hectares of wildflower meadows are being planted across Hampshire and Sussex this autumn as part of the South Downs National Park’s Bee Lines project, a bold effort to reverse the steep decline of Britain’s pollinators. The initiative creates continuous wildflower corridors linking farms, schools, and even cemeteries, effectively building a ‘road system’ for bees, butterflies, and hoverflies to move through the landscape without interruption.
The scheme, launched in 2020, has already funded 37 restoration projects through the South Downs Trust, including Blacknest Fields in Binsted, Hampshire. Volunteers there have recorded 30 butterfly species, over 30 bee and wasp species, and 190 moth species since the meadow opened to the public in 2022—up from zero prior. Sarah Womersley, a volunteer at Blacknest Fields, said, “We’ve gone from barren grass to a thriving ecosystem in just five years.”
💡 Pro Tip
Leave patches of bare soil in your garden this winter; solitary bees nest in undisturbed ground and will lay eggs in spring.
Jan Knowlson, biodiversity officer for the South Downs National Park, warned that one in three bites of food in the UK depends on pollinators, which have declined by 30% since 1980. “Climate change and habitat loss are hitting these insects hardest,” Knowlson said. “But we’re seeing early signs of recovery where corridors are established. It’s not too late to act.” The Bee Lines project is part of the wider ReNature campaign, which aims to restore biodiversity across the 1,600 square kilometres of the national park by 2030.
| Pollinator Threat | Impact | Solution |
|---|---|---|
| Habitat loss | 97% decline in wildflower meadows since 1930 | Corridors connecting fragmented habitats |
| Climate change | Shifts in flowering seasons disrupt pollinators | Diverse, staggered planting schedules |
| Pesticide use | Reduces bee foraging efficiency by 50% | Integrated pest management on partner farms |
The latest phase of Bee Lines involves planting native species like oxeye daisy, red clover, and bird’s-foot trefoil—plants that support specialist pollinators. The project has secured £1.8 million in funding from Natural England and local councils, with an additional £600,000 raised through public donations. Organizers aim to double the area of wildflower habitat to 200 hectares by 2026.
📋 By The Numbers
- 1 in 3 — Bites of food dependent on pollinators
- 30% — Decline in UK pollinator populations since 1980
- 1,600 km² — Size of the South Downs National Park
- 37 — Restoration projects funded to date
Landowners, schools, and community groups can still join the scheme by applying for grants up to £10,000. Applications close on December 15. Knowlson urged the public to help on a smaller scale: “Even a 1m² patch of wildflowers in a garden or window box can make a difference.” The national park has launched a public map showing all Bee Lines sites, updated weekly with new plantings and sightings.
Key Points
- ✅ 100 hectares of wildflower corridors planted in 2024
- ⚡ Blacknest Fields now hosts 30+ butterfly species and 30+ bee species
- 💡 Public can still apply for £10,000 grants to create new pollinator habitats
The project’s rapid progress has drawn attention from conservation groups, including the Bumblebee Conservation Trust and Butterfly Conservation, which are collaborating on monitoring and data sharing. Early data from 2023 shows a 22% increase in bumblebee sightings in areas connected by Bee Lines compared to isolated patches. Researchers at the University of Sussex are tracking pollinator movement using microchips attached to bees, confirming the corridors are being used as intended.
- First — Wildflower corridors reduce pollinator travel time between food sources by up to 40%
- Second — Diverse native plants support specialist species like the shrill carder bee, once thought extinct in the region
- Third — Community-led monitoring has recorded 12 new species at Bee Lines sites since 2022
With winter planting underway, the South Downs National Park is calling on landowners to dedicate a corner of their land to wildflowers. Jan Knowlson emphasized the urgency: “Every hectare counts. The bees and butterflies can’t wait.”
