General Meetings and Presentations

CNPS Event July 21, Wednesday: Casual Picnic /Get-Together(6pm) and Presentation (7pm): A Novel Mountain Rockcress of the Eastern Sierra, Speaker: Tamsen Dunn; In-Person and Zoom Options for Attendance! Bishop City Park - details below. Bristlecone Chapter Event .

In 2004, Dr. Alison Colwell, Yosemite Rare Plant Specialist (now curator of the UC Davis Herbarium) collected an inconspicuous, intermediate-looking mustard plant high in the Clark range in southeastern Yosemite. She sent seeds to her colleague Dr. Elizabeth Waters at SDSU to grow and analyze, who discovered that the plant had unusual heat tolerance, surpassing even its desert-dwelling relatives. Genetic analysis showed that this strange plant, labeled “FW1102,” conformed to no known species, but contained sub-genomes of three other Boechera lineages. Intrigued, graduate student Tamsen Dunn decided to investigate further. Tamsen’s presentation will describe potential sites in Inyo and Mono counties where FW1102 may have been found in the past. She will share what we know of this interesting plant and may also bring a live specimen from SDSU to show the group and let chapter members know where they can keep a lookout for these special plants in the mountains!

Tamsen is a third year graduate student in the joint doctoral program at San Diego State University and the University of California Riverside, where she is studying evolutionary biology, with an emphasis on botany and genomics. After 10 years as a scientist at Illumina, Tamsen felt it was time to combine her interest in DNA with her love of native plants, conservation and remote mountains. Tamsen's current research interests include molecular evolution, polyploidy, hybridization and somatic variation. Tamsen enjoys rock climbing and collecting plant samples in the high Sierra with her young daughters.

Meet at Bishop City Park at 6:00 pm, Wednesday, July 21, under the veranda just west of the Senior Center (682 Spruce St). Picnic tables are available, but you may prefer your own chairs and/or picnic blankets. You may bring a dish to share, or if you are more comfortable not sharing food, bring your own food, snacks, and/or drinks.

Alternatively, attend by Zoom for the presentation at 7 pm. Zoom information: Topic: Bristlecone Chapter Dunn presentation Time: Jul 21, 2021 07:00 PM Pacific Time (US and Canada) Join Zoom Meeting

CNPS Event December 16, 6pm: Bristlecone Chapter - Eastern Sierra Audubon Joint Holiday (Zoom) Party, with speaker Deanna Dulen: A Mosaic for Re-Wilding Damaged Landscapes: Climate Refugium, Forests, and Birds

Join the Bristlecone Chapter and Eastern Sierra Audubon for a virtual holiday party and presentation. We'll start with announcements from 6-6:30 before the program at 6:30-7:30: A Mosaic for Re-Wilding Damaged Landscapes: Climate Refugium, Forests, and Birds Presented by Deanna Dulen. What are the possibilities of re-wilding some of the lost and degraded habitats ravaged by climate change including intense mega-fires? This presentation will present some information on the emerging field of Climate Refugia and fire recovery science, and some of the experimental efforts in collaborating with birds to restore lost forests. We'll end with a Q&A Session at 7:30-and wrap-up by 8:30 pm.

Deanna Dulen

Deanna retired in June 2020 after a 37 year career as a civil servant. She served as Superintendent at Devils Postpile National Monument since 2000. During her tenure she contributed leadership in resource stewardship and climate change adaptation with a focus on climate refugia research, and fire and fuels management. Deanna worked as the first Director of the Mono Basin Scenic Area Visitor Center for 10 years developing interpretive and science communications programs and exhibits. She worked as an interpretive ranger at Grand Canyon, Yellowstone, Denali, and Death Valley, as a firefighter on the Olympic National Forest, and as a letter carrier with the US Postal Service to fund her college education at UC Santa Cruz where she graduated with highest honors in Environmental Studies. She plans to continue travelling with her husband and his travel business, Sherpa Travel, and to contribute to international work in Nepal with a non-profit she and her husband founded in 2012, Friends of Himalayan Sherpa to improve the quality of life in the remote and rural Himalayan villages through education, health care, and protection of natural and cultural resources.

Past Presentations with Recordings:

CNPS Event September 23, Wednesday: 7pm, Bristlecone Chapter Virtual General Meeting: California Desert Protection and Desert Flora - Recording available here if you missed it!

Virtual presentation by co-speakers Bryan Hatchell and Maria Jesus.

Bryan Hatchell, whose talk, "Desert Protection and Plant Connection" was canceled in March due to the pandemic, is the Desert Lands Organizer with Friends of the Inyo, and looks at energy development threats in the California Desert Conservation Lands. Plans that guide conservation and renewable energy development in the desert may rapidly change, which strengthens the need of continued advocacy for conservation and science. He will share landscape level issues and then narrow in on what neat desert plants that exist at each site of concern.

Maria Jesus whose April talk at the Maturango Museum and May field trip to Conglomerate Mesa were both cancelled due to the pandemic, is a master’s student at Rancho Santa Ana Botanic Garden/Claremont Graduate University and a 2019 Switzer Fellow. Maria is researching the flora of the Southern Inyo Mountains, Inyo County. She states, “Here, Joshua trees, emblematic of the Mojave Desert, give way to Pinyon and Juniper woodlands which are characteristic of the Great Basin Desert. This unique transition zone is home to many endemic and rare plants including Hesperidanthus jaegeri, Nemacladus ‘inyoensis’, and Perityle inyoensis.” During her presentation, Maria will share her preliminary results of her floristic research, including new occurrences of rare taxa and an update on the conservation status of Conglomerate Mesa.

The recording of this program is available here.
