The Society of Municipal Arborists (SMA) Board recently voted to make City Trees freely available to everyone. Here’s how you can access City Trees, an international, bimonthly online magazine about all things urban forestry. 
From the Sept/Oct 2022 link (or any other issue link) you can see past (to 2011) present and future issues via the Folder Icon.
You can also sign up for City Trees via MailChimp if you want a link delivered to you every (bimonthly) issue. 🌳
