Description

The County of Orange is seeking a qualified contractor to provide seed amplification and coordination services that will ensure a reliable supply of genetically appropriate native seeds for the County’s ecological restoration projects. The contractor will manage seed‑multiplication contracts with growers, oversee production under Southern California conditions, perform seed cleaning and testing, and act as the liaison between the County, growers, and other land‑management agencies. The effort supports the Orange County Native Seed Partnership and aims to reduce reliance on wild seed collection, improve genetic diversity, and meet the Habitat Restoration and Enhancement Plan requirements. • Provide coordination among County staff, growers, and partner agencies. • Amplify native seed stocks using field or container production methods. • Manage seed‑production plots ranging from 50 sq ft to 1 acre. • Conduct seed cleaning, processing, and initial testing at no extra charge. • Deliver seed in pure live seed (PLS) pounds as forecasted by the County. • Submit safety plans, IIPP, and compliance documentation. • Attend a mandatory pre‑submittal virtual meeting on Oct 13, 2026. • Submit a full electronic proposal by Nov 19, 2026, 2:00 pm.

Budget estimate

$150,000 – $500,000

The solicitation does not disclose a contract value. Based on comparable county‑level ecological restoration contracts that cover seed production, coordination, and consulting, a reasonable estimate would be in the low‑to‑mid six‑figure range per year. Factors influencing the final amount include the number of species to be amplified, the acreage of seed‑production plots, and the length of the contract term (often 1‑3 years).
