'Hybrid Organ': How a Union of Trees and Fungi Could Revolutionize Forest Management
A US startup supplies spray for fast-growing loblolly pines with the hope of increasing biodiversity – and reducing the need for artificial fertiliser.

TL;DR
- Funga, a startup, is spraying pine seedlings with liquid extracts of wild soil fungi to improve growth and reduce the need for artificial fertilizers.
- The treatment aims to restore depleted underground fungal networks (ectomycorrhizal fungi) essential for pine tree nutrient absorption.
- This approach is compared to a microbiome transplant for trees, using complex fungal communities rather than isolated species.
- The goal is faster-growing trees that absorb more carbon dioxide, with less dependence on fossil-fuel-based fertilizers.
- Commercial pine harvests significantly deplete soil fungal diversity, impacting young trees' growth for decades.
- Funga's early trials show promising results, with growth responses exceeding 100% in some cases and targeting an average 30% boost.
- The company funds its operations through carbon removal deals, including a contract with Netflix, aiming to address issues like non-additionality and impermanence in carbon markets.
- Funga plans to expand its treatments to other tree species and regions, including Douglas fir in the Pacific Northwest and trials in Wales.
