*As seen on the “Jason Alexander Show” for the Palisades/Eaton Fire Cleanup* (See Audio or Video)
Aside from two generations totaling over 40 years of tree work, the Mayfield team has tackled hazard trees and forestry across wildfire disasters including the Lahaina Fire, Camp Fire/Paradise, and Palisades. We were among the largest private HAZMAT contractors in the Palisades/Eaton Fire disaster, including assessing the viability of protected oaks.
In California, the typical response is to call landscapers and tree contractors, but these “arborists” have no actual arborist certifications or any knowledge in tree-related sciences. They are tree-trimmers.
Instead, let Mayfield provide you with ISA-Certified Arborists and “Tree Doctors“ with decades of experience, degrees, and knowledge of plant biology, botany, mycology, and ecosystem sciences. Unlike our competitors, we also have the knowledge and licenses in geotechnical engineering, HAZMAT, Biohazard, and earthwork that lets us bring the experience in soil chemistry, plant disease like Sudden Oak Death Syndrome, soil chemistry concepts like Cation Exchange Capacity (CEC) and allelopathy, and more. Being HAZMAT contractors, we also bring the edge of knowing how chemicals and toxins in the air, runoff, and surface affect plant and tree health. We also bring another benefit that our competitors don’t have with our Pest Control/Agriculture licenses (QAL) that make us experts in pesticide impacts on the ecosystem, not to mention the impacts of bark beetles, tree borers, oak moths, and invasive species for biological studies (protected animals and plants, etc.).
Among other Oak-related services, we provide expertise in oak tree counting, oak health assessment, oak-related permitting (removal, arborist clearance), soil remediation, wildlife surveys, biological studies assistance, and more.
For our integrated tree health care, We are also experts in environmental sampling for bioassay analysis, foliar analysis, pesticide testing, testing for infectious disease and fungal (mold spore) outbreak, soil sampling and soil chemistry, water sampling and air quality monitoring, and more.
