Seed Scaling for Restoration
How native seed scaling production works
Ecological restoration at scale requires seed production at scale. At St. Williams Ecology Centre, we operate Ontario's largest field-based native seed production system—growing hundreds of species across habitat types to supply municipalities, utilities, conservation authorities, mine reclamation projects, and restoration practitioners.
Native Species Diversity
We maintain production capacity for up to 300+ Ontario native species depending on demand forecasting. Our core species for bulk seed production from field grown wild-type seed include:
- Prairie and meadow grasses: Big Bluestem, Little Bluestem, Indian Grass, Canada Wild Rye
- Wetland species: Sedges, rushes, Joe Pye Weed, Swamp Milkweed
- Woodland and savanna species: Wild Bergamot, Black-Eyed Susan, Grey-Headed Coneflower
- Pollinator and forb diversity: Milkweeds, asters, goldenrods, native legumes
Our production fields rotate species based on restoration forecasting, regional demand, and habitat priorities across the province. We currently produce 1,000–2,000 kg of native seed annually, beyond what we maintain in cold storage. This volume supports:
- Municipal meadow and naturalization programs
- Hydro corridor and utility right-of-way restoration
- Mine reclamation and industrial site rehabilitation
- Conservation authority habitat projects
- Private land restoration and stewardship initiatives
Field-Grown for the Long-Run
Today, many restoration projects are based on agricultural production of unverified native seed and small-scale wild-collection, which is limited by what's available in any given year. Our model is different. We plant, tend, and harvest native seed crops in dedicated production fields, using regionally adapted genetics and agricultural methods that scale. This approach takes years following the natural patterns of restoration, but saves time compared to natural cycles. This ensures:
- Consistent supply for multi-year projects
- Volume capacity for large restoration initiatives
- Species diversity beyond what wild collection can provide
- Quality control through managed production and seed cleaning
Who We Supply
Our production supports large-scale restoration across many sectors including:
- Municipalities planning naturalization and meadow conversion programs
- Utilities and infrastructure partners restoring hydro corridors, roadways, and rights-of-way
- Conservation authorities implementing habitat restoration and species recovery projects
- Mine reclamation programs requiring large volumes of regionally adapted seed
- Restoration consultants and practitioners coordinating multi-year ecological projects
Long-Term Production Partnership
Working together, we can build the seed system Ontario's landscapes need. If you're planning restoration work in Ontario, we want to hear about it—years before you break ground. Restoration forecasting improves supply stability. Multi-year planning aligns ecological goals with biological production cycles.
