Forest3, based in Berkeley, California, develops small machines that carry out forest work semi-autonomously. Its equipment is aimed at two parts of forest management: fire prevention and precision harvesting.

The goal is to extend what forest professionals can do: more ground covered in less time, and safer work for the people doing it.

coolant.earth builds 3D digital twins of forest properties from aerial drone photographs, which a landowner can take with a drone they already own. Its AI then measures every tree in the model instead of sampling a few plots, and the results come back as maps and tables: species, height, trunk diameter, damage and defects, timber products, and modeled biomass and carbon. One flight serves timber inventory, forest management and carbon projects, and a property can be flown again for monitoring.

In August 2025 we tested coolant.earth’s drone mapping at San Domingo Arbory.

EmberEye makes an early-warning system for wildfire. A network of low-power infrared sensors, which can be mounted on trees, watches for the heat signatures and flame flicker of a new ignition and sends a rapid alert before the fire has time to spread. Monitoring runs around the clock, and the cloud-based alerts are meant to help fire departments and utility companies act sooner.

EmberEye plans where the sensors go with geospatial fire-risk modeling, so that monitoring is concentrated where the risk is highest, such as fire-prone landscapes, utility corridors and wildland next to communities.

Calaveras Tree Care is a tree care and consulting arborist practice based in Murphys, working in the Sierra Nevada since 2009. Its services run from consultations and written arborist reports to tree inspections, whether of one tree or thousands, including inspections for real estate sales and tree risk assessments.

It also does pruning, diagnoses and treats tree pests, diseases and disorders, advises on bark beetle management and on protecting trees during construction, and writes management plans for anything from a single tree to many acres of forest or woodland, with goals that can include fuel reduction.

Jay’s Tree Service is a family-owned company based in Bear Valley, California. For more than six years it has worked a six-month season each year on sustainable forest management and wildfire prevention, removing hazardous dead trees and brush to lower wildfire risk and make room for healthy regrowth.

By its own count, the crew handles about 3,960 tons of dead wood and logs and 1,678 tons of slash and brush in an average year, and it has spent four years on fire-safe and forest improvement projects with the county.

Two Crows Ecological Design is an ecological design and contracting firm based in Sebastopol, California. Its designs begin with how water moves across a piece of land, then work new development and agriculture into the ecosystem already there, with the aim of rebuilding soil and habitat.

At San Domingo Arbory, around April 30 to May 2, 2025, it restored the old flume trail and a ridgetop fuel break first cut during the 2015 Butte Fire, on a hillside that burned in the 1992 Old Gulch Fire: the first framework for the restoration work there. At Woodland Hilltop Arbory it planned and built the walkable trails. The trails give access for fuel reduction and restoration work and help manage water on the hillsides.

micro1 is a data research company for artificial intelligence. It recruits domain experts whose real-world work becomes training data, builds training environments modeled on real tasks, and runs evaluations that test how AI models and agents perform. Its robotics work records experts at hands-on tasks, from household and industrial jobs to field operations, in first-person and third-person views. It turns those recordings into labeled training data and tests robots end to end in a lab of its own.

micro1 sponsors DeepForest’s work and develops robotics for field applications like those at our sites.
