Plant Atlas Project of Arizona
here 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.

Yellow Bluestem (Bothriochloa ischaemum) is a perennial grass introduced to the United States from Europe and Asia in the early 1900s as a way to control erosion and as a forage species. In the past several years, this species has become an emerging invasive in Arizona, negatively affecting the habitats it invades in many ways including Our meeting schedule is set for the season. economically, environmentally, and/or ecologically.

In this talk, Dr. Bronstein looks at the women who were publishing in a leading biological journal, The American Naturalist, in the first fifty years of its publication (1867-1917). How did they enter science, and under what conditions were they able to persist, either as professionals or as publishing amateurs? What lessons can we take away for how to increase diversity in science today?

Judie Bronstein is University Distinguished Professor of Ecology and Evolutionary Biology at University of Arizona. She served as the first (and, to date, only) female Editor-in-Chief of The American Naturalist, the oldest still-publishing scientific journal in the United States. She has a strong interest in the history of science.
