"We planted 40,000 Douglas fir here. The elk came back in eighteen months."

"Every root tip is a decision. If it spirals, the tree suffers for decades."
Ingrid has spent eleven years perfecting the conditions that give seedlings their best chance before they ever touch open ground. Her greenhouse in the Willamette Valley holds 200,000 seedlings at peak season — Douglas fir, western red cedar, bigleaf maple — each one started from locally-sourced seed to preserve the genetic memory of the watershed it will return to.

Tomás Guerrero
Aerial Survey Lead · Post-Fire Response Team
"The drone sees erosion channels forming before the first rain arrives. That is when we can still act."
Before a single sapling goes in the ground, Tomás flies it. His LiDAR surveys map slope angles, soil compaction, and residual seed banks at 4-centimeter resolution — the data that determines species selection, spacing, and planting sequence. Last year his team surveyed 47,000 acres across three post-fire landscapes, producing planting plans that reduced erosion runoff by 62% in the first growing season.

The scale of the work
Individual hands become crews, become aerial surveys, become recovering hillsides. Here is how a single planting site transforms across five years.
Crew 7, Deschutes Watershed — October 2025
8 people · 4,200 trees planted over 5 days
Aerial survey — 1,200 acres · Clackamas Watershed
Five years on one hillside
Bare hillside after wildfire
Ash soil, zero canopy, active erosion on 30° slopes. Tomás maps the site. Ingrid begins seed collection.
12,000 saplings planted
Douglas fir, red alder, and native shrubs go in during the October rain window. Crews of eight work five-day rotations.
First canopy closure begins
Alders reach 8 feet. Nitrogen fixing begins. Elk tracks appear at the creek crossing. Marisol records the first spotted owl call.
Watershed function restored
Stream temperature down 4°C. Salmon redds reappear in the lower reach. The hillside holds rain. The site is closed to new planting.

"We were skeptical of carbon offset programs. Grove brought us to the site. We walked it. We funded it. That was three years ago — we've been back every spring since."
