I’ve put a walking tour of the Salesforce Park up on youtube - you can find it here (or just search youtube for “Salesforce Park Walking Tour”). It’s an iPhone video - in the tour, i walk around the park’s 4 block loop, identifying trees and plants as I go. If you prefer a tour where you can see the names of the trees, you can find that one here on this website: if you’re on a desktop or laptop, just click the link above titled “Salesforce Park Walking Tour”; if you’re on a smart phone, click the navigation link at the top of your screen, and choose the link by the same name.
