What is the Riparian Plant Propagation Program?

The Riparian Plant Propagation Program (RPPP) increases the availability of native trees and shrubs needed for riparian restoration. By supporting the growth and distribution of native plant materials, the program helps expand riparian habitat along salmon-bearing streams and provides the many co-benefits that healthy riparian areas bring to local communities and ecosystems.

Eligibility

Conservation districts and nurseries.

About this Conservation Program

By coordinating with nurseries and restoration groups, including conservation districts, RPPP expands the availability of native trees and shrubs for riparian restoration by:

  • Identifying the number and species of native plants needed
  • Coordinating seasonal propagation schedules
  • Providing financial support to expand native plant nursery stock
  • Matching plants with riparian restoration projects
  • Building community through outreach, education, and engagement opportunities

RPPP is implemented through three phases:

  • Propagation: Partnering with nurseries to increase propagation of native trees and shrubs for districts and restoration projects. SCC supports this work through 2–4 year contract grows, enabling long-term planning and access to difficult-to-source species.
  • Cultivation: Providing annual funding to conservation districts for creating new holding sites, expanding existing facilities, and purchasing plants ready within the fiscal year. Holding plants for 2–3 years improves survival rates, and sites may also serve as nursery overflow.
  • Restoration: Distributing locally grown plants to riparian habitat projects led by districts, non-profits, state and federal agencies, Tribes, counties, and other partners.

Climate Commitment Act (CCA) Requirements

RPPP received additional funding from Washington’s Climate Commitment Act (CCA), which directs cap-and-invest dollars to reduce climate pollution, create jobs, and improve public health. Learn more at climate.wa.gov.

For any SCC grant program funded by the CCA, applicants must notify all affected federally recognized Tribes within the project area as early as possible prior to funding approval. This requirement is separate from cultural resource reviews and cannot be combined.  See scc.wa.gov/cd/cca for all Climate Commitment Requirements.

The notifications must follow the instructions below:

Notification emails must include:
