Why “And Fungi”?

Why have fungi in my business name? Fungi are the drivers of so many positive and negative outcomes in tree health and viability. I have spent well over a decade exploring forests studying fungal diversity, working as a consultant for an agricultural amendments company on mycorrhizal species. Being a consultant arborist who has spent almost all his life in El Dorado county, I have been able to monitor individual trees for decades and what how they respond to different wood decay fungi, weather patterns, shifts in land use, and fire. I have spent countless hours searching for spores with a microscope, reading research papers, and talking to wide variety of experts who have spent their lives in the forest to grasp how we can keep our trees and forest healthy and free from catastrophe.
