Parking near the NAU campus is very difficult, but the Mountain Line #10 bus stops right in front of the building. For more information visit the Deaver website or contact session organizers Gisela Kluwin or Vera Markgraf

Museum of Northern Arizona
The Museum of Northern Arizona is looking for dedicated volunteers to assist in the curation of herbarium specimens including identifying specimens, mounting pressed specimens, filing pressed specimens into the herbarium, and georeferencing specimens. The Museum is also looking for volunteers to help plant, weed, and prune the native plants in the Colton Research Garden, at the Colton House, and around the Museum grounds. For more information, please contact Museum botanist, Kirstin Phillips.

The Arboretum at Flagstaff
Our Southwest Butterfly House is open Wednesday-Monday from 10:00-4:00. We are looking for volunteers to assist staff on weekends Shifts are 10:00-1:00 and 1:00-4:00.  Training and resoures are provided. Contact Volunteer Coordinator Shannon Benjamin at Shannon.benjamin@thearb.org or 928-774-1442 ext. 127.

Grow Flagstaff Seed Library
The Grow Flagstaff Seed Library is looking for volunteers to help create seed packets to add to the growing seed library. For more information, please contact Jackee Alston.

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.

Rachel Burke presents: “Mapping nectarivorous bat habitat from the nectary up”

Posted on Jul 22, 2021

Rachel Burke – Mapping nectarivorous bat habitat from the nectary up; implications for Agave conservation in the southwestern U.S. From a Flagstaff chapter presentation in July, 2021.

The lesser long-nosed bat (Leptonycteris yerbabuenae), Mexican long-nosed bat (Leptonycteris nivalis), and the Mexican long-tongued bat (Choeronycteris mexicana) undertake long‐distance migrations from south‐central Mexico to the southwestern United States. Following a corridor of seasonal food availability, these bats play important ecological roles as pollinators and seed dispersers throughout their ranges. While these bats feed on many species of plants throughout their ranges, Palmer’s agave (Agave palmeri) is among one of the most important food sources in the summer portion of their range. As part of a landscape scale project to better understand summer habitat and inform management for these bat species, I mapped the distribution of Agave palmeri at multiple scales and assess summer habitat quality via plant density and potential nectar production. This information can help managers better protect important foraging grounds for these bats and identify potential restoration sites for Agave palmeri.

Rachel Burke is a biologist based in Las Cruces, New Mexico. She has a master’s in Fish, Wildlife, and Conservation Ecology, as well as in Applied Geography, both from New Mexico State University. She currently works as a wildlife biologist for the U.S. Bureau of Land Management and has spent several years conducting botanical surveys and ecological monitoring across the Chihuahuan Desert. When not working, she can be found cultivating native plants in her garden, making pottery in her basement, or hiking with her dogs.

Kate is a farmer, floral designer, writer and visual artist who is wild about plants. She makes her livelihood from Wild Heart Farm, a one-acre oasis in Rimrock, next to Beaver Creek. She grows flowers, medicinal herbs, and pollinator habitat, and hosts plant gatherings. She worked in service to wild plant communities for 20 years in the Grand Canyon and across the Colorado Plateau, always aware and curious about plant/pollinator interactions. Kate has developed land-based artist
residencies and workshops and co-curated exhibits with scientists and artists to advocate for pollinators and public lands. To follow her entrepreneurial and artistic adventures arising from the soil visit: www.wildheartfarmaz.com and www.katewattersart.com.

September 21: Liza Holeski – Plant Defenses Against Herbivores 

Liza is an Associate Professor in Biology at Northern Arizona University.  Her research focuses on plant evolutionary ecology and genetics.  She is interested in plant adaptation to biotic and abiotic environmental factors, plant-herbivore interactions, and the evolutionary genetics of plant defense traits.  Much of her work is in monkeyflowers, but she also works with Populus species. Liza’s presentation will give a general overview of plant defenses against herbivory, describing the forms of defense as well as highlighting some particularly interesting examples.  She will also talk a bit about her research in plant defense in monkeyflowers as she works with a number of natural populations of monkeyflowers in Arizona.

October 19: Wynne Brown speaks about the subject of her new book – The Forgotten Botanist: Sara Plummer Lemmon’s Life of Science and Art 

The Forgotten Botanist

Wynne Brown’s latest book is the account of an extraordinary woman who, in 1870, was driven by ill health to leave the East Coast for a new life in the West—alone. At thirty-three, Sara Plummer relocated to Santa Barbara, where she taught herself botany and established the town’s first library. Ten years later she married botanist John Gill Lemmon, and together the two discovered and collected hundreds of new plant species , many of them illustrated by Sara, an accomplished artist. Although she became an acknowledged botanical expert and lecturer, Sara’s considerable contributions to scientific knowledge were credited merely as “J.G. Lemmon & Wife.” 

Writer/editor/graphic designer Wynne Brown is the author of the award-winning books More Than Petticoats: Remarkable Arizona Women (Globe Pequot Press/Rowman & Littlefield, 2003, 2012) and The Falcon Guide to Trail Riding Arizona (Globe Pequot Press/Rowman & Littlefield, 2006) and the co-editor of Cave Creek Canyon: Revealing the Heart of Arizona’s Chiricahua Mountains (ECO Wear & Publishing 2014, 2019). Her most recent book, The Forgotten Botanist: Sara Plummer Lemmon’s Life of Science and Art, will be published in November 2021 by the University of Nebraska Press. She serves as president of the Chiricahua Regional Council and represents Pima County as a member of the Arizona Historical Society State Board of Directors. Her website is www.wynnebrown.com.
