McMillan Mesa

MM photo croppedThe City of Flagstaff acquired McMillan Mesa Natural Area in November 2016 after approximately 86% of Flagstaff voters voted in favor of its preservation. The 300-acre McMillan Mesa Natural Area is one of the last intact native grasslands within the City and provides habitat for elk, deer, and other mammals. Studies of the Mesa have uncovered multiple cultural and historic resources, including the Beale Wagon Road. McMillan Mesa provides beautiful views of the San Francisco Peaks and Mt. Elden, as well as many recreational opportunities.

Open Space Status

Since the preservation of McMillan Mesa Natural Area with the passing of Proposition 413, the City has been working to align guiding documents to better manage the property. The Flagstaff City Council approved a major plan amendment on October 16, 2018, which went into effect on November 15, 2018. Currently, City staff are working to finalize a zoning code amendment, which proposes to rezone the property to Public Open Space from its current Public Facilities and Rural Residential zoning. This process already included two virtual public meetings (December 2020 and January 2021) and a 60-day public comment period. Final steps for completion of the proposed zoning code amendment include creating a new legal description for the Natural Area, completion of a cultural survey documenting historic and prehistoric archaeological resources, additional city staff review of the rezoning application, a public hearing with the Planning & Zoning Commission, and City Council review and decision. Once a date for the Planning & Zoning Commission meeting is selected, a formal notification and the selected date will be published and shared with the community.

Restoration in McMillian Mesa Natural Area improves native habitat

Six large invasive Russian Olive trees, and over 100 invasive Siberian Elm trees were removed along the Flagstaff Urban Trail System (FUTS) and Arizona trails on McMillan Mesa.  In line with the McMillan Mesa Natural Area Management Plan priorities, removing invasive trees and plants improves the habitat and preserves natural diversity of species. This work allows native plantings to thrive, protects this native grassland from tree encroachment, maintains and enhances a diversity of habitats that support native wildlife, and makes the area more resilient to wildfire. 

To replace some of the invasive trees, we planted baby Ponderosa Pines between the new Veterans Home and the FUTS, and we need folks to adopt a tree, by visiting their new tree 2-3 times per week to water them until they are established. Email with any questions or to adopt a tree.
