Frequently asked questions

Arbory is the word DeepForest uses for a forest site dedicated to restoration and active management. At an arbory, hands-on forestry, ecological science and new technology work together to rebuild a resilient forest ecosystem, and we measure what works.

An arboretum is a collection: it displays and studies many tree species, often planted side by side for comparison, education and enjoyment. An arbory is a working forest under restoration. Its goal is a healthy ecosystem rather than a collection: a mix of trees suited to the place, lower wildfire risk, soils and water that hold together, more carbon stored in trees and soil, and more habitat for wildlife. That means thinning overly dense thickets and clearing deadwood, replanting native species, improving soils, managing water and watching how the land responds year after year.

Visits are by invitation only: the sites are private, working land. Please contact us before you come.

Members of our patron circle have access to the project sites and are invited to members-only events.

Yes. Researchers and startups can propose work at the sites, from short field tests of sensors, drones, robots and models to longer research projects. Start with Work With Us and tell us what you'd like to try.

Camera, drone and satellite records can be shared with research collaborators on request. Locations of sensitive wildlife and heritage information stay protected. Each site page lists its data streams; start with Work With Us.

Slash from thinning and brush clearing is turned into biochar in a steel ring kiln. Biochar is a stable charcoal that keeps much of the wood's carbon out of the air and may improve soils. Any carbon figures we share are our own estimates; this is not a certified or registry-tracked carbon credit.

Many of our projects are funded directly by private supporters. Members of our patron circle have access to the project sites, members-only events and opportunities to work directly with DeepForest staff, sites, and technology. Ask for information or to join.
