July 7, Thursday, 6 pm: The Archeological Identification and Radiocarbon Assay of Pre-Colonial Nüümü (Paiute) Agriculture in Payahuunadü (Owens Valley), Journal of California and Great Basin Anthropology - ZOOM

The existence of Nüümü (Paiute) agriculture in the Payahuunadü (Owens Valley) was formally documented greater than 170 years ago. Since that time, only limited effort has been directed towards the identification of extant Nüümü agricultural features. In 2017, an inter-disciplinary study was initiated to address this gap in the record. The results of an episodic multi-year investigation into irrigation systems in the Owens Valley are reported herein. A Nüümü irrigation system was archaeologically identified, and a series of radiocarbon dates indicative of pre-Columbian agriculture are advanced. These data support agriculture being established in the northern Owens Valley prior to 547 +/- 35 BP (639-512 cal BP) (D-AMS 035291).

Authors: Gregory Haverstock (speaker), Angela Jayko, BLM and WMRC, Harry C. Williams (deceased), Nüümü (Paiute) Elder, Bishop Paiute Tribe

July 14-17: Volunteer Backcountry Stewardship Week-West Walker River Drainage Bridgeport, CA, Friends of the Inyo

Join Friends of the Inyo and the Bridgeport Ranger District of the Humboldt-Toiyabe National Forest for a spectacular three days of stewardship in the Hoover Wilderness. We’ll be working to monitor weed species in the West Walker River drainage and taking care of any trail issues we come across. And we’ll also save plenty of time for hiking, sharing stories, and enjoying a beautiful place. Training will be provided. Space is limited—RSVP now to to ask questions or hold your spot for this backpacking trip. More information at:

July 14-17, 2022: Sky Island Flora of the White Mountains, Jepson Herbarium Workshop, Jim Morefield and Marty Purdy, White Mountain Research Center, Bishop and Crooked Creek. Workshop is full! Waitlist only.

The White Mountains are located at the southwest corner of the Great Basin floristic region, and their geologic and habitat diversity, high relief (spanning 4,000-14,246 feet elevation), and proximity to the Sierra Nevada and Mojave Desert all contribute to an unusually rich and well-documented flora of over 1,100 taxa. They are also known for the oldest living trees, the highest point in Nevada, and the third highest peak in California. By mid-July, the subalpine and alpine floras are coming into their peak blooming periods.

Through driving tours (up to 50 miles each day) and easy to moderate hikes (up to 4 miles), participants will have the opportunity to explore the southern half of the White Mountains, observing and identifying diverse plants and learning to recognize various geologic and ecologic settings that influence species distributions and adaptations. Thursday morning, we will start from Bishop and stop at several points up the elevation gradient to our weekend base station at Crooked Creek (10,000 feet). Friday and Saturday will be spent visiting wetland and upland sites in various geologic settings at elevations up to 13,000 feet, depending on seasonal conditions. Sunday morning will include additional field time before our final lunch stop as we leave the mountains.

Accommodations: Shared dormitories with bathrooms.
Meals: Provided by field station.
Transportation: Vehicles must have good clearance and sturdy tires (including spare!). Carpooling possible. High clearance 4x4 with extra passenger space preferred.
Hiking: Easy to difficult: If we go up any steep and/or rocky hillsides, it will be very slowly while we look at plants, and the distances will be pretty short. Participants should use their discretion if they will be able to adjust quickly to hiking at elevations above 10,000 feet.
Start/End: Thursday morning - Sunday afternoon.
Course Fee: $550/$580.

August 13, Saturday, 9-12:30: Hydrology of the Sierra Nevada at Virginia Lakes with Bradley Olson, Friends of the Inyo

Virginia Lakes Trailhead Come hike with Trail Ambassador Bradley Olson up Virginia Lakes Canyon and learn about the hydrology of the Sierra Nevada. Discussions will include how water shaped the Sierra in the past and created the many ecosystems we see today and how crucial water will be to the area in the future. Space on this hike is limited to 12 folks. RSVP online at:

CNPS Event August 15: September-October Bristlecone Chapter Newsletter Deadline

Today is the deadline for submissions for the March-April Bristlecone Chapter Newsletter to our Newsletter Editor, Elaine Chow, at Contact Elaine with any questions.

CNPS Event August 16-19: Native Plant Sale - Bristlecone Chapter Event

Participate in the Bristlecone Chapter’s Plant Sale to purchase your garden’s native plants for the fall season. Invite passing pollinators to your outdoor space and celebrate the new gardening season! Our online store for the plant sale will be live from Tuesday, August 16th through Friday, August 19th to place orders. Once orders are submitted, buyers will receive instructions to schedule pick up for their orders at White Mountain Research Center (3000 E. Line St., Bishop) on Saturday, August 20th. Current members will be able to access the online sale a day earlier (on August 15) after receiving the link to the site by email. So, members, make sure your membership is not expired in August to ensure you’ll get that email in time! (Go to, log in or set up your profile to confirm your membership status and opt in to receive emails from CNPS.)

Leftover plants from the online sale will be available to buy on the 20th. Click here for a list of plants that have been available at past sales. Proceeds from the annual native plant sales provide funding for our Mary DeDecker Botanical Grants. The grant program is a fitting way to remember Mary DeDecker’s many contributions to the people and plants of the Eastern Sierra.

September 22 – 25, 2022: Some Like It Hot: Late Summer Flora of the Eastern Mojave Highlands, Jim André and Tasha La Doux, Sweeney Granite Mountains Desert Research Center, Jepson Herbarium Workshop Workshop is full! Waitlist only.

The Eastern Mojave Desert represents one of the most floristically diverse regions in California. This incredible diversity is, in part, due to the region's proximity to the North American Monsoon and its prominent summer rainfall regime. Approximately 10% of eastern Mojave annuals are considered "summer annuals," species that germinate following summer rainfall. In addition, more than 25% of perennial species in this region flower in late summer/early fall. Examples of plant families that respond to summer rain include: Nyctaginaceae, Amaranthaceae, Euphorbiaceae, Polygonaceae, Poaceae, and Asteraceae. This course will introduce botanists to the ecology and taxonomy of the diverse late summer/early fall flora in the eastern Mojave Desert, with special emphasis on rare or unique species. Through field observation, lab identification, and evening presentations, participants will gain a better understanding for the major plant families that comprise the hot-season flora. This field-intensive workshop is intended for botanists with moderate to advanced taxonomic training, but also for those with an interest in learning more about this seldom-seen component of California's flora. Field trips will target the mid to higher elevations of the Mojave National Preserve, planned in accordance to optimal blooming conditions.

Note: Drop dead deadline = August 31, 2022 - workshop will be cancelled without sufficient rain.

Accommodations: Shared dormitories with bathrooms. Tent camping will also be available.
Meals: Catered meals - dinner Thursday through lunch Sunday included.
Transportation: Vehicles must have good clearance and sturdy tires (including spare!). Carpooling possible. High clearance 4x4 with extra passenger space preferred.
Hiking: Easy to moderate; short hikes in sometimes rugged terrain and desert conditions (sun, heat, wind).
Start/End: Thursday 4pm - Sunday 12:00 pm.
Course Fee: $570/600

The California Native Plant Society (CNPS) is a state-wide 501(c)3 non-profit organization of lay persons and professionals who share an interest in California’s native plants. The Society, working through its local chapters, seeks to increase the understanding of California’s native flora and to preserve this rich resource for future generations. Membership is open to all.

The Bristlecone Chapter covers all of Mono and Inyo Counties and northeastern Kern County, an area that includes the east slope of the Sierra Nevada, the Northern Mojave Desert, the Inyo and White Mountains, and the Owens Valley. The southern end of the Bristlecone Chapter’s geographically large territory, in and around the Indian Wells Valley, has its own sub-chapter, Creosote Ring.
