About The Canopy Tree Library

Canopy arborists and City of Palo Alto arborists joined forces to create a tree selection tool customized to our area

Many tree lists and selection tools are available on the web, but none address the specific needs of residents and professionals of our local region.

A team of Canopy and City of Palo Alto arborists have worked for many months to create an easy-to-use tool that encapsulates their more than 150 years of professional arboriculture and urban forestry experience. This is a unique and invaluable tool that will help residents and professionals understand trees better and select species for successful plantings with confidence.
