Oak-led food forest in a canyon landscape

Core Mission

Where the Oak Canopy Meets the Stream

Our 3.2-acre site in the San Gabriel foothills is a laboratory for drought-resilient abundance. Leveraging the shade and nutrient cycles of ancient California Live Oaks, we've developed a food forest model that thrives in the chaparral transition zone.

"The oak does not struggle against the canyon heat. It drinks from the deep stream and builds soil for the generations that follow."

Soil Science

Riparian Resilience

Our biochar integration program is tailored for the specific microbial needs of canyon soils. By mimicking the natural charcoal cycle of the chaparral, we have achieved a 45% increase in soil carbon, significantly improving water retention in the foothills.

Hydrology

Managing the Canyon Pulse

Managing water in a seasonal canyon ecosystem requires a blend of capture and conservation. Our systems leverage the natural stream flow and terraced swales to maintain soil hydration through the dry Southern California summers.

  • 4,200 gallon total storage capacity
  • Zero-pump gravity-fed distribution
  • Integrated swale and keyline design
  • Seasonal overflow to recharge pond

Current Programs

Six interconnected research streams feeding data into our open-source regenerative agriculture knowledge base.

Chaparral Permaculture

Testing polyculture systems tailored for the California chaparral, utilizing drought-hardy perennials and oak-canopy microclimates.

4 growing seasons tracked

Biochar Integration

Inoculating canyon soils with locally-produced biochar to increase water retention and sequester carbon in the rugged San Gabriel foothills.

45% soil carbon increase

Food Forest Design

Seven-layer food forest model adapted for Mediterranean-alpine transition zones with companion planting and nurse tree canopy experiments.

12 species in trial

Mycelium Networks

Mapping existing fungal networks and testing their role in inter-plant communication and nutrient transfer across our food forest plot.

6 species identified

Water Harvesting

Gravity-fed rainwater collection designed for steep mountain terrain. Swale and keyline design integrated with food forest plantings.

4,200 gal capacity

Canyon Microclimate Mapping

24/7 sensor array tracking temperature, humidity, and airflow patterns across the steep canyon terrain to optimize planting zones.

Lab History

From Bare Land to Living Lab

2021

Site Acquisition

Secured 3.2-acre rugged parcel in the San Gabriel National Forest corridor, specifically in a diverse canyon ecology below Mount Baldy.

2022

Infrastructure Build

Installed 16-node sensor array, gravity-fed water collection system, and established first test beds with native soil baseline measurements.

2023

First Growing Season

Planted 12 perennial species across 8 polyculture zones. Began biochar soil amendment trials with control and inoculated plots side-by-side.

2024

Canyon Network Mapping

Mapped 8 native fungal species forming communication networks between oaks and new plantings. Published dataset on chaparral food forest performance.

2025

Expansion Phase

Scaling successful polyculture models to full food forest. Installing additional water harvesting capacity and hosting first seasonal research cohort.
