In 2016, Mast was founded in Seattle, Washington, with the mission to make reforestation scalable to mitigate the effects of climate change and restore forested landscapes devastated by wildfire or other disturbances.
Today, we operate in all states west of Colorado. We’ve also done projects in Western Canada and taken our work internationally with trials in New Zealand and Australia. We are the first and only company with FAA approval to operate heavy-lift swarms of drones.
To scale reforestation with the backdrop of a critically low nationwide seed supply, Mast acquired Silvaseed in 2021 and Cal Forest in 2022.
The acquisition of Silvaseed, a 130-year-old forestry seed bank and seedling nursery, along with Cal Forest, the supplier of the majority of seed and seedlings used for reforestation in California, makes Mast the largest seed supplier in the Western U.S.
Mast is the only vertically-integrated company to offer all reforestation services including seed collection, seedling cultivation, site preparation, seedling hand planting, aerial drone-based seeding, and ongoing site monitoring.
Maximize reforestation efforts with traditional planting of seedlings. Access hard-to-reach or dangerous terrain and jumpstart natural regeneration with aerial enhanced seeding with drones.
We curate an ever growing supply of wild seeds from native tree species that will become resilient forests.
Our nurseries are growing millions of seedlings. By 2023, we plan to more than double our nursery capacity to better serve the needs of our local communities.
Revenue from carbon removal offsets offer landowners the opportunity to be compensated for the CO2 that the planted trees will sequester over time to cover high upfront costs of reforestation efforts.
