🌿Downland Restoration to Enhance Traditional Calcareous Grassland
Brief
Habitat Regeneration was commissioned by a private landowner to deliver a Natural England-funded downland restoration project on a private estate in Surrey. The objective was to restore and enhance traditional calcareous grassland by reversing scrub encroachment and implementing a long-term management programme to protect and strengthen this nationally important habitat.
Challenge
Lowland calcareous grassland is one of the UK’s rarest and most species-rich habitats, with around 97% lost since the 1930s. Found on thin, freely draining chalk and limestone soils, these grasslands support an exceptional diversity of wildflowers, pollinators and other wildlife. Without appropriate management, scrub can rapidly invade, swamping and outcompeting the species-rich grassland and reducing its ecological value.
On this Surrey estate, scrub encroachment had begun to dominate areas of the downland, requiring carefully planned restoration works to reinstate favourable conditions while safeguarding the habitat’s long-term ecological value.
Solution
Habitat Regeneration developed and delivered a phased restoration programme tailored to the site’s environmental characteristics and conservation objectives.
Works commenced during the autumn and winter of 2024 with the careful thinning of encroaching scrub that had been swamping and outcompeting the calcareous grassland. Programming the scrub clearance outside the bird nesting season ensured the works were undertaken in accordance with ecological best practice while minimising disturbance to breeding birds.
A 13-tonne excavator equipped with a tree shear, tree saw and mounted mulcher head was used to efficiently thin, process and manage scrub across the site. On the steeper and more challenging slopes, a Robocutter remote-controlled mulcher enabled vegetation clearance to be completed safely and effectively where conventional machinery could not operate.
Following the initial restoration, cut and collect operations were carried out during the 2025 and 2026 seasons after grasses and wildflowers had shed seed. A tractor-mounted cut and collect machine removed the seasonal vegetation arisings, reducing nutrient levels within the sward while allowing characteristic calcareous grassland species to naturally regenerate and flourish.
The restoration programme is complemented by native sheep and goat grazing, providing ongoing vegetation management to maintain the open character of the downland, suppress scrub regeneration and support the long-term resilience of the habitat.
Working closely with the client, Habitat Regeneration combined ecological expertise, specialist machinery and practical delivery to implement a restoration programme that balances habitat enhancement with sustainable long-term management.
Outcome
The project has restored and enhanced a valuable area of traditional calcareous grassland, creating improved conditions for characteristic wildflowers, pollinators, invertebrates and other wildlife.
By carefully sequencing autumn and winter scrub clearance, post-seed-shed cut and collect operations, and ongoing conservation grazing, the project is helping to secure the long-term future of one of Britain’s most threatened habitats. The phased management approach is improving habitat condition, encouraging greater botanical diversity and supporting sustainable land management for years to come.
The project demonstrates Habitat Regeneration’s ability to combine ecological knowledge, specialist machinery and practical delivery to provide end-to-end habitat restoration solutions that maximise environmental outcomes.
