Planting trees is important, but caring for them for the first 3 years of their life is vital for survival. On average, urban trees have a life span of 8 years. Our City Forest is here to provide you with the resources needed to change that statistic to 80 years. See below for links to resources you can download.

Why Hire An Arborist?

It's important to verify the license of any person who claims to be a tree service provider. Don't let anyone prune your trees without the proper certification. An ISA certified arborist can determine the type of pruning necessary to improve the health, appearance, and safety of your tree.

How to find an Arborist

The International Society of Arboriculture (ISA) is the professional association that certifies arborists. Visit ISA's website for a Directory of Certified Arborists.


Below is a link of Tree Care Companies that have registered with the City of San Jose. These companies have shown that they have the proper Workers Compensation and Liability Insurance. It does not guarantee the quality of work performed. You should still confirm that they have certified arborists through the ISA website.
