Native seed harvesting for wildflower meadows, nature reserves, BNG schemes and ecological restoration: preserving local genetics while delivering measurable habitat outcomes
CDTS North & West operates a custom-built brush harvester that collects ripe seed from donor sites without damaging the source vegetation. Our low-ground-pressure equipment and in-house processing facility allow us to supply local-provenance seed for projects where commercial mixes cannot deliver the genetic diversity or site-specific adaptation required for BNG sign-off, nature recovery networks, or sensitive conservation work.
What Brush Seed Harvesting Delivers On Site
Brush seed harvesting collects native seed from species-rich donor sites for re-establishment on receptor sites. The counter-rotating brushes gently strip seed heads without removing plants, preserving the donor site while capturing a wide range of species that commercial suppliers cannot provide.
Local Provenance & BNG Compliance
Native seed ensures the species composition matches local soil, climate and ecological character. This genetic match improves establishment rates and satisfies BNG requirements for locally-appropriate habitat creation, reducing the risk of post-establishment failure.
Minimal Site Disturbance
Our ATV-towed harvester uses low ground pressure to access donor meadows, heathlands and grasslands without compaction or rutting. Within days of harvesting, the donor site shows no visible disturbance, making this method suitable for SSSIs, nature reserves and conservation areas.
Cost-Effective Restoration
Where donor sites are available within the project area, brush harvesting eliminates the need for expensive commercial seed purchases. A single day of harvesting typically yields enough seed for one hectare of establishment, reducing material costs while ensuring ecological authenticity.
Where Brush Seed Harvesting Fits on Your Project
Brush seed harvesting is specified when projects require genetic provenance, rare species inclusion, or site-specific adaptation that commercial seed cannot deliver. It's the proven method for BNG schemes where planning conditions mandate local-provenance establishment, for habitat translocation projects adjacent to development sites, and for restoration work where donor sites contain target species unavailable from commercial suppliers.
Commercial seed mixes provide baseline grass and wildflower establishment but cannot replicate the genetic diversity or minor species composition of semi-natural grasslands. Where BNG conditions specify local ecotype establishment, where nature recovery networks require genetic continuity between habitat patches, or where rare species translocation forms part of protected species mitigation, brush harvesting captures the full species assemblage including sedges, specialised forbs and grasses that seed suppliers do not stock.
BNG & Biodiversity Schemes
Local-provenance seed for BNG compliance where commercial mixes fail to deliver target species composition or genetic diversity requirements.
SSSIs & Nature Reserves
Gentle collection method suitable for sensitive donor sites where mechanical disturbance must be minimised to protect existing vegetation.
Motorway & Railway Verges
Harvesting seed from adjacent high-quality verges for re-establishment after construction, maintaining corridor connectivity for pollinators.
Quarry & Brownfield Sites
Collecting seed from nearby semi-natural grassland to establish locally-adapted habitat on restored sites without importing alien genetics.
How Our Brush Seed Harvesting Process Works
01
Donor site assessment
We evaluate donor sites with your ecologist to confirm species composition, seed ripeness and collection volumes. Access routes are planned to minimise disturbance, and collection timing is scheduled to match optimal seed maturity windows.
02
Collection
The ATV-towed brush harvester combs through standing vegetation at calibrated height and speed. Ripe seed is stripped into the hopper while plants remain rooted and undamaged. Multiple passes may be made depending on target species and seed density.
03
Seed processing
Collected seed is transported to our facility for air-drying on sheets. Once dry, material is threshed to separate viable seed from stalks and chaff, then cleaned and bagged with full donor site traceability and species composition records.
04
Receptor site preparation & sowing
The receptor site is prepared to remove weeds and create an open seedbed. Processed seed is typically sown via hydroseeding for even distribution without deep burial, or by conventional broadcast methods depending on site conditions and specification.
Why Choose CDTS for Your Project?
Brush seed harvesting projects fail when contractors lack suitable equipment for gentle collection, fail to properly dry and clean seed, or cannot coordinate donor site access with receptor site preparation windows. Poor collection technique damages donor sites, mixed species fail to establish, and BNG conditions remain unsigned. CDTS removes these risks through specialist equipment, in-house processing facilities, and proven coordination across collection-to-establishment timelines.
Custom-built brush seed harvester
We operate a purpose-built brush harvester towed by low-ground-pressure ATV, allowing access to wet or soft donor sites while minimising compaction. Adjustable brush height and speed ensure clean seed collection without stripping stalks or damaging plants.
In-house seed processing facility
Our facility air-dries collected seed on sheets before threshing to separate seed from chaff. This controlled process ensures viable seed is ready for sowing, with full traceability from donor site through to establishment.
30+ years establishment experience
CDTS has delivered wildflower and native grassland projects since 1991. Our team understands donor site selection, optimal collection windows, seed viability testing, and receptor site preparation - ensuring harvested seed establishes successfully rather than failing through poor handling.
