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 almost two decades exploring forests studying fungal diversity and 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, California, 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, forests, and ecosystems healthy.
