Native Seed Collection and Nursery Propagation

Provenance matters

Restoration plant material should be genetically appropriate to the site — local adaptation affects survival, flowering time, and wildlife compatibility. Wild collection and nursery propagation require permits and ethical protocols.

Seed collection guidelines

1. Collect from multiple mother plants across the population (avoid single-tree bottleneck).
2. Harvest at physiological maturity — not too green, not after heavy predation.
3. Record GPS, elevation, and habitat for provenance documentation.
4. Never collect more than 10–20% of available seed on a plant unless salvage situation.

Nursery propagation

Some species require stratification, scarification, or smoke treatment to break dormancy. Others propagate from cuttings or division. Container vs bareroot stock affects planting season and transplant success.

Genetic policy

Many agencies publish seed transfer zones — planting outside zones risks maladaptation or outbreeding depression with local genotypes.
