Got Weeds?

If so, this website was built for you. Its purpose is to provide facts and photos that will help residents of northern Arizona identify and control the invasive plants most likely to be found in their yards and neighborhoods. Even if these invasive plants are not in your yard today, they are still a threat to your property if they are already growing along a nearby road, in an adjacent field or forest, or on your neighbor’s property.



Coconino Master Gardener Association Blog

The mission of the Coconino Master Gardener Program is to support the University of Arizona by providing researched-based information on environmentally responsible gardening and landscaping to the public. The program creates a corps of well-informed volunteers, and delivers quality horticultural education programs adapted to our regional high elevation environment. The mission of the association is to provide support for those volunteers and Master Gardener graduates, continuing education, and opportunities to participate in community programs that increase the visibility and participation in the Master Gardener Program.

Plant Atlas Project of Arizona

There are several plant ongoing plant atlas projects in northern Arizona. The Plant Atlas Project of Arizona (PAPAZ) is a statewide partnership between the Arizona Native Plant Society, Grand Canyon Trust, Desert Botanical Garden, Northern Arizona University, Museum of Northern Arizona, and the U.S. Forest Service to document the diversity and distribution of Arizona’s flora. For more information, see the Plant Atlas Project website or contact Kirstin Phillips.


Weed Warrior Activities

The AZNPS Flagstaff Chapter will join forces with the Grand Canyon Trust, Master Gardeners, and other local organizations to tackle the enormous weed problem along Fort Valley Road between the Fire Station, Trust's headquarters, Pioneer Museum and the Museum of Northern Arizona.

Invasive plant species tend to be aggressive, to outcompete native plants for resources and space, and to decrease biodiversity. Diffuse Knapweed, Kochia, Bull Thistle (below), Cheatgrass and many other species are present throughout our project focus area. Together we can work to remove them and increase the chances for native grasses and flowers to flourish. There has already been major improvement at the Pioneer Museum, and native species are filling in among the native grasses. However, there is still more work to do. Details about these projects are on the Grand Canyon Trust's website. Please come out and join local weed warriors and plant enthusiasts for one or all three workdays of weed removal, exercise, and fun. Please contact Dorothy Lamm with questions or just register at the website. See you there.
