Rhizocore

Unlocking nature’s hidden helpers to grow resilient forests

What is the Challenge?

With timber demand projected to quadruple by 2050 and massive reforestation efforts underway, the world needs trees to grow robustly and quickly across vast landscapes. Yet, reforested areas often lack the natural fungal partners that trees depend on for accessing nutrients, especially in nutrient-poor soils where many new forests need to be planted. Without these fungi, newly planted trees face reduced growth rates and increased vulnerability to drought, disease, and climate-driven stresses, jeopardizing reforestation and carbon sequestration efforts.

What is the Solution?

Rhizocore is revolutionizing reforestation by building the world’s largest living fungal library, preserving and reintroducing critical fungi needed for healthy forest growth. For each planting site, Rhizocore selects fungi specifically adapted to the local environment and trees, delivering them through the RhizoPellet—a small pellet dropped in the planting hole alongside the tree. The fungi then form a natural symbiosis with the tree, helping it access essential nutrients and water, which dramatically boosting survival rates and accelerating growth up to 13 times in nutrient-poor soils.

This approach not only strengthens trees but also enhances carbon capture by storing additional carbon underground in the root system, fungal structures, and soil itself. Mycorrhizal fungi already draw down 13 gigatons of carbon each year, and each RhizoPellet increases this impact while enhancing soil biodiversity and ecosystem resilience, helping create thriving forests that support our planet’s future.
