Our Story

Mast is the world’s first and only end-to-end tech-led reforestation company.

As bigger and hotter fires destroy more forestland every year, many landowners are left without good reforestation options. Mast Reforestation uses technology to provide faster and more resilient forest restoration at no cost to the landowner. 

Mast's Unique Model

Mast encompasses a portfolio of trusted companies: Silvaseed, a 130-year-old nursery and the largest seed supplier in the Western U.S., Cal Forest Nurseries, which supplies the majority of trees for California’s reforestation and DroneSeed, which provides aerial seeding services and is where Mast got its roots.
