Sound Native Plants

What Sound Native Plants does

Sound Native Plants is a privately-held environmental consulting and ecological restoration company headquartered in Olympia, Washington, with a second regional base in Portland, Oregon. Founded in 1992 by Ben Alexander and Susan Buis, both former National Park Service restoration project implementers, the company provides consulting, installation, and maintenance services for native plant restoration, green stormwater infrastructure, and bioengineering projects across western Washington and northwest Oregon. The company operates two regional field crews — SNP South (Portland/Vancouver) and the Southern Salish region (Olympia) — serving clients from Tacoma, WA to Salem, OR and from the Cascade Crest to the Pacific coast.

The company's core technology rests on practical expertise in Pacific Northwest ecosystems, including native plant species selection, fascine installation and other bioengineering techniques (live staking, coir erosion control fabrics, vegetated geogrid), integrated weed and invasive species management, and green stormwater infrastructure installation. The team holds Oregon and Washington Commercial Pesticide Applicator licenses, enabling herbicide application as part of restoration work. Sound Native Plants also maintains an extensive online knowledge base — a Species Descriptions Database, Species Selection Guide, and Plant Quantity Calculator — that codifies 30+ years of institutional knowledge. The company closed its native plant nursery at the end of 2022 and no longer produces plants, instead referring customers to partner growers.

The business model is professional services-based, with revenue generated from hourly consulting engagements ($100/hr in-person, $150/hr virtual) and project-based installation and maintenance contracts. The customer base is primarily government agencies (federal, state, county, and municipal), supplemented by corporations (forest products, energy), non-profit land trusts and conservation organizations, and a smaller segment of private landowners. The longest-standing commercial relationship is a 17+ year partnership with the City of Portland's Green Streets program. In 2024, founder Ben Alexander retired and transferred ownership to Chad Stemm, a 22-year employee who had managed SNP South since 2002.

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Anchor QEA: Large PNW-based environmental engineering and restoration consulting firm with offices in Seattle and Portland. Broader portfolio than SNP (water resources, contaminated sites, planning) but directly competes for ecological restoration and green infrastructure contracts in the same geography.
• Aspect Consulting: PNW-based water resources, geotechnical, and environmental consulting firm with restoration and stormwater practice. Comparable in serving municipalities and government agencies on green infrastructure and ecological projects, with broader engineering capabilities.
• Herrera Environmental Consultants: Seattle-based environmental consulting firm offering habitat restoration, watershed planning, and bioengineering services across the PNW. Comparable as an incumbent competitor on restoration and green stormwater projects, with broader multi-disciplinary capabilities.
• Mason, Bruce & Girard: PNW forestry, natural resources, and environmental services firm offering ecological restoration, habitat enhancement, and silviculture. Comparable in serving forest products and government clients in the Pacific Northwest, with a broader forestry practice than SNP.

Regional players

• Mountains to Sound Greenway Trust: Nonprofit focused on ecological restoration, native plant installation, and habitat connectivity across the I-90 corridor from Seattle to Central Washington. Comparable as a PNW restoration practitioner, though operating as a non-profit land trust model rather than for-profit services.

Others

• Lower Columbia Estuary Partnership: Non-profit restoration program operating in the lower Columbia River estuary with overlapping client relationships to SNP. Listed as an SNP customer/partner; represents the non-profit restoration ecosystem that SNP serves as a contractor.
• Wildlife Conservation Society (regional PNW initiatives): While national in scope, WCS runs field programs in ecological restoration that intersect with SNP's client base. Functions as an adjacent conservation ecosystem player rather than direct competitor.
• Fourth Corner Nursery: PNW wholesale native plant nursery explicitly named by SNP as a referral partner after the SNP nursery closed. Comparable as a native plant supplier in the same ecosystem, representing the upstream supply chain SNP now depends on.

Direct peers

• Natural Systems Design: PNW-based environmental consulting firm specializing in stream and wetland restoration design, bioengineering, and habitat restoration. Directly comparable as a competitor in the same geography delivering ecological restoration and green stormwater services to government and tribal clients.
• EarthCorps: Seattle-based nonprofit performing ecological restoration across the Puget Sound region, including native plant installation, trail building, and habitat restoration with crews analogous to SNP's field delivery model. Directly comparable as a PNW-focused restoration practitioner serving government, tribal, and non-profit clients.
