Soil health is essential to forest health. But what constitutes soil health? Biologist Frank Piccininni takes us on a journey to the life underground at West Hills County Park. There, he will show how fungal networks help determine the composition of the forest above, what trees and plants flourish where, and how invasive plants disturb the order of things below and therefore above.
