Volunteering Opportunities

Want to get involved? We've got just the thing!

Northern Arizona University, Deaver Herbarium
We are looking for dedicated volunteers to help mount pressed specimens for the permanent collection. No experience necessary, training will be provided. No reply needed, just show up and join a fun group.Work sessions will take place every first and third Friday of the month at 1:30 to 3:30pm in the Deaver herbarium in the Biological Sciences Bldg on 617 S, Beaver Street. The herbarium is located in room 314 on the south side of the third floor.

Next Sessions:

  • October 18
  • November 1
  • November 15

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
The Arboretum at Flagstaff offers volunteer opportunities in the gardens, greenhouses, education, events and visitor center.
We are open from May-October. For more information, please contact Delaney Donnelly at: delaney.donnelly@thearb.org

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.

Fall 2023 Chapter Meetings

Posted on Aug 24, 2023

Regular evening programs are presented on the third Tuesday of the month, March through October, at 7:00 PM via Zoom. Some of the meetings have been recorded and can be viewed the Flagstaff Chapter’s Facebook or at The Arizona Native Plant Society. For details about upcoming meetings, please see our email distribution list (naris123@cs.com), Facebook page, or AZNPS.com. Field trips are typically held the weekend following the evening presentation. Watch the email distribution list for information about upcoming field trips.

Tuesday, September 19, 7:00 PM: Andrew Salywon. Using Trained Dogs to Detect Endangered Spiranthes delitescens
The objective of this work is to determine the ability of detection dogs to identify the presence of Spiranthes delitescens. If successful, the use of detection dogs would be a powerful tool to aid future surveys to relocate historical populations or discover previously undocumented populations of Canelo Hills ladies’ tresses. Utilizing trained dogs and their powerful sense of smell can greatly aid conservationists by making plant surveying much more efficient, thus requiring less human effort and resources. Spiranthes delitescens have recently been observed in small numbers at only one of four historically documented sites.

Tuesday, October 17, 7:00 PM:

Lane Butler. Assessment and Status of Rumex orthoneurus, a Rare and Vulnerable Forest Service Conservation Agreement Species on the Tonto National Forest

This talk will tell the story of Rumex orthoneurus on the Tonto National Forest from the late seventies to the present. How have populations changed? How has management changed? What actions have been taken to conserve the species under Conservation Agreements? What is the species status today and what does its future look like? Lane will address these questions and more.
Lane Butler is currently working on several rare and endangered plant conservation grants at the Desert
Botanical Garden. She enjoys hunting for (and finding!) rare plants, especially flowering Arizona hedgehog cacti on the Tonto National Forest. In 2015, she earned her Master of Science at ASU in Plant Conservation Biology in the riparian plant community ecology lab. Her project emphasized the relationships of plant and butterfly abundance and diversity to stream-flow permanence along Sonoran Desert streams.

July Flagstaff Chapter AZNPS meeting July 18th, 7 PM, Nora Ventrella – Rare and Restoration Plants of The Navajo Nation

Posted on Jul 02, 2023

The July meeting of the Flagstaff Chapter of the AZNPS will be the third Tuesday, July 18th, at 7 PM via Zoom.  You will need to register ahead of time to get a Zoom invitation.Nora Ventrella – Rare and Restoration Plants of The Navajo Nation; Conservation Activities of the Navajo Natural Heritage Program

Nora Ventrella has been the botanist for the Navajo Natural Heritage Program with the Navajo Nation Department of Fish and Wildlife for the past 6 years. As a part of this program she collects, manages, and disseminates information on threatened and endangered plant species on Navajo lands, and is the curator of the Navajo Nation herbarium located in Flagstaff. This talk will cover monitoring and conservation efforts by NNHP focused on threatened and endangered plants of the Navajo Nation. This talk will also focus on seed banking and plant propagation activities conducted by the newly created Diné Native Plants Program; a tribally-run restoration program focused on bringing native and culturally-important plants back to tribal lands.

Nora has her master’s degree in plant biology and conservation from the joint program between Northwestern University and the Chicago Botanic Garden. Her research background focused on Colorado plateau flora, invasive species, local adaptation, and seed sourcing for restoration.
