From Wiki:
Simard asserts that healthy forests centre on a matriarch tree that acts as a nexus of nutrient distribution that shares these nutrients among other trees of the same or different ages and species that are chemically and physically linked together by an expansive mycorrhizal network. Simard faced ridicule during her younger years; however her research became “critical to addressing problems in the timber industry” that led to reforms in sustainable forestry.
