Modesto’s Forestry Division takes care of the City’s extensive urban forest. This includes all of the City’s street and park trees, as well as the trees outside government buildings. Our staff are highly trained, and have had decades of experience in tree care. We are proud to have one of the highest ratios in California of ISA (International Society of Arboriculture) Certified Arborists. Many of our Arborists have additional ISA Certifications in specialized areas such as Tree Risk Assessment and Municipal Tree Care.
