Board Certified Master Arborist providing arborist reports, tree risk assessments, fungal pathology reports, Oak Resource Management Plans, and plant health care.
Consulting Arborist Serving El Dorado County, Sacramento County, Placer County and Northern California
Sierra Tree and Fungi is the independent consulting practice of Christopher Hodge, an ISA Board Certified Master Arborist (WE-14385B) and TRAQ qualified tree risk assessor serving El Dorado, Sacramento, Placer, and Amador counties, California. A consulting arborist diagnoses and documents trees but does no removal work, so the advice is conflict free. I provide tree risk assessments, arborist reports, plant health care, and Oak Resource Management Plan reports, and I help property owners make informed decisions, preserve the trees they value, and steward their land.
We have no removal crews and no financial incentive to recommend unnecessary work, just documented, conflict free advice from an ISA Board Certified Master Arborist with TRAQ qualification.

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.
