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

McMillan Mesa Natural Area was first preserved with the passing of Proposition 413. The Flagstaff City Council approved a major plan amendment on October 16, 2018, which went into effect on November 15, 2018. On February 15, 2022, the Flagstaff City Council adopted a resolution amending the existing zoning of the McMillan Mesa Natural Area from "Public Facilities and Rural Residential Zoning" to Public Open Space (Zoning Map Amendment application PZ-20-00063), and this became official on March 31, 2022!  So why are there buildings and construction going on at the top? Before Prop 413, some of the land was private property. Click on the Zoning Map link to see the boundaries of the Natural Area.

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.

Major funding for this project provided by the AZ Department of Forestry and Fire Management’s Urban and Community Forestry Program and the USDA Forest Service. These institutions are equal opportunity employers.
