SEATTLE — Climate tech company Mast, the newly-formed parent company of DroneSeed, announced its acquisition of California-based Cal Forest Nurseries, which supplies the majority of seedlings used for reforestation in California. Mast restores forests after large-scale wildfires with reforestation projects that generate high quality carbon removal credits. With the acquisition of Cal Forest, Mast addresses a major obstacle to scaling reforestation: an inadequate supply of tree seed and seedlings. The company chose its new name, Mast, from the forestry term describing the once or twice per decade phenomenon in which multiple trees simultaneously produce a large crop of seed-bearing cones. The addition of Cal Forest strengthens Mast’s vertical integration in response to reforestation supply chain challenges due to bigger, hotter, wildfires driven by climate change. By combining technology and legacy forestry practices with seed and seedling supplies, Mast can execute an ever-greater number of post-fire reforestation projects in partnership with landowners.
