Finding California wood is easier than you think.
Source reliable California-grown material from small producers and landowners who know their forests, steward the land, and bring care to every board — all coordinated through one point of contact.
The CA Wood Supply Group is coordinated by the Watershed Research and Training Center, a nonprofit practicing community-based forest stewardship since the 1990s.
You are not sourcing blind. You have a vetted contact, clear lead times, and a single point of coordination at every step.
What you get
We handle the complexity of local sourcing so you can focus on the project.
Reliable Sourcing
The right material for your project, secured from vetted California producers with realistic capacity and clear lead times.
One Point of Contact
Pricing, production, and delivery coordinated through a single relationship—so you don't have to manage multiple suppliers.
Specify With Confidence
Documented species, grades, and specs, with verified chain of custody—material you can put on a drawing and stand behind.
A Story Worth Telling
Every piece of wood has a story. Our chain of custody and traceability services can help support your sustainability goals or simply communicate a story worth celebrating.
California imports 80% of its solid sawn lumber—while local logs go unused.
We're building the market that changes that, and making California-grown wood easy to specify and source.
How it works
Three steps from project requirements to delivered material.
Tell us what you need

One point of contact from start to finish
From pricing and production through delivery, we coordinate the process so you don't have to manage multiple suppliers.
For Builders & Architects
The Easy Button
Local wood sourcing shouldn't feel like a gamble. Here's exactly what happens, who's responsible, how long it takes, and how we reduce your risk at every step.
Tell us what you need
Share your project requirements—species, volume, dimensions, timeline, and any special specs. That's it. One conversation starts the process.
Contact
Submit a request through this site, or call/email our team directly. You talk to one person—not a list of mills.
Who's responsible
You provide the requirements. We confirm receipt and begin sourcing immediately.
Timeline
Acknowledgment within 1 business day. Initial sourcing options within 3–5 business days.
Risk reduction
No commitment at this stage. We scope feasibility and alternatives before you make any decisions.
We match, price, and confirm
We work our vetted producer network to find the right material, confirm pricing, and lock in realistic lead times—then come back to you with a clear proposal.
Contact
Your same CWSG contact coordinates everything. You never need to call a mill, kiln, or hauler directly.
Who's responsible
We identify producers, confirm capacity, verify specs, and assemble your quote. You review and approve.
Timeline
Formal quote and lead-time confirmation typically within 5–10 business days, depending on species and volume.
Risk reduction
Pricing compared to conventional channels. Substitution options identified upfront. No surprises on cost or schedule.
Production, delivery, and documentation
Once approved, we manage production coordination, drying and finishing, delivery logistics, and documentation—from the mill to your job site.
Contact
Still one point of contact. We provide production updates and coordinate delivery timing with your project schedule.
Who's responsible
We coordinate milling, drying, finishing, and delivery. You receive material with verified specs and chain-of-custody documentation.
Timeline
Lead times confirmed at order approval. Production milestones and delivery windows communicated throughout.
Risk reduction
Moisture verification, documented grading, and chain-of-custody records through AncesTREE. Material you can stand behind on the drawing and in the field.
No guesswork. No chasing down mills, kilns, or haulers. One process, one contact, start to finish.

Why California wood
Specifying local material does more than meet a sustainability checkbox—it's a decision your clients will want to hear about.
Forest health & wildfire resilience
Sourcing from fuels-reduction and post-fire utilization helps keep California's forests healthier and more resilient—material with a real impact behind it.
California's forest economy
Every order keeps value-add processing and jobs in-state, supporting rural communities and a wood economy that has long lost work to imports.
Local sourcing credits
Support sustainability goals and local sourcing credits without adding procurement complexity.
Codes & alignment
Tracking CalGreen and EPD pathways, with an alignment roadmap for evolving codes.
Hard-to-find material
Access to California-grown species and custom material you can't easily source elsewhere.
