Past Presentations with Recordings:

CNPS Event September 23, 2020, 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.
