About Mast Reforestation

Mast Reforestation operates at the critical intersection of climate technology and ecological restoration, focusing on the escalating challenge of post-wildfire recovery in Western North America. The company was founded to address the increasingly destructive nature of wildfires, which are outpacing natural regeneration cycles. Mast Reforestation provides a vertically integrated solution, starting from seed collection and seedling cultivation to on-the-ground planting and long-term forest management.

Read full description

The company's business model is multifaceted, generating revenue through reforestation services, the sale of high-quality seedlings, and the generation of carbon removal credits. Its target clients include private landowners, corporations seeking to meet their ESG and carbon neutrality goals, government agencies, and non-profits. A core component of their strategy involves acquiring and operating key assets within the forestry supply chain. Mast owns Silvaseed, a 150-year-old institution, and Cal Forest Nurseries, positioning it as a dominant player in the Western U.S. forestry sector. These nurseries are pivotal, producing an average of 36 million seedlings annually and managing the seed supply for a vast region.

The service portfolio is comprehensive, encompassing everything from site-specific reforestation plans to the use of technology for planting and monitoring. The company emphasizes a science-based approach to create resilient forests capable of withstanding future climate pressures. By combining traditional forestry expertise with modern logistics and technology, Mast Reforestation is building a scalable model to restore thousands of acres of burned forestland each year. This process not only rebuilds ecosystems but also provides a tangible method for carbon sequestration, turning a climate problem into a viable economic and environmental solution.
