The Arboretum at Flagstaff response to COVID-19 pandemic

Dear Friends,

We hope this message finds you in good health and good spirits! At this time, The Arboretum at Flagstaff is planning to open to the public May 1, 2020. However, all public buildings will remain closed until further notice. This includes the Visitor Center, Horticultural Center and Research Greenhouse, and the public restrooms. Please know that due to the rapid changes in safety practices, our open status could change very quickly. Please check the website frequently, especially before heading out.

Please remember, that as a nonprofit The Arboretum relies on memberships, admissions, ticket sales to events and classes, and private rentals to support our mission. Your donation directly supports our organization’s general operations and helps maintain the collection of plants.
Thank you for your continued support!

Kristin Haskins, Ph.D.
