Both members and visitors are welcome at our regular meetings, held at Eaton Canyon Nature Center beginning at 7:30 p.m. on the fourth Thursday of each month except July, August, November, and December. The meetings are preceded from 7:00 to 7:30 p.m. by social time and informal plant identification.
Allium sp. Thursday, June 28, 2018, 7:30 p.m.: Talks by two of our award recipients: This month we have 20-minute talks from two CNPS San Gabriel Mountains Chapter award recipients. Sophie Winitsky is a second year Masters Student at Rancho Santa Ana Botanic garden and received a student research grant in 2016 from the CNPS San Gabriel Mountains Chapter. She will be presenting an update on her research project. Dylan Cohen is a PhD student at Rancho Santa Ana Botanic Garden and was awarded a stipend to attend the CNPS Conservation Conference. Dylan's talk covers the research he presented at the conference.
Black Lake A vascular flora of the Adobe Valley and surrounding hills, Mono County, CA, with Sophia Winitsky: This study aims to document the vascular flora of the Adobe Valley and surrounding hills in Mono County, CA. Less than 100 herbarium specimens are recorded from the 90 square mile study area based on a search of the Consortium of California Herbaria, with little botanical documentation away from well-established roads or in the alkali meadows. At the center of the study area the U.S. Fish and Wildlife Service manages the River Spring Preserve, a 638-acre alkali and freshwater wetland. The preserve emphasizes the importance of the alkali flat ecosystem, a habitat that is representative of Owens Valley, but severely threatened by drought, trampling by cattle and feral horses, off-road vehicles, and water diversion. Alkaline ecosystems farther south have experienced more severe water pumping making the Adobe Valley a good place to establish baseline information to better understand sustainable groundwater extraction. In addition, there is a need for a floristic checklist of the River Spring Preserve as specified in the Preserve's 2016 Management Plan. Many endemic species have the potential to occur in the Adobe Valley and surrounding hills, so far Sophia has documented the following California Native Plant Society listed species: Allium atrorubens var. cristatum (Alliaceae), Calochortus excavatus (Liliaceae), Ivesia kingii var. kingii (Rosaceae), Cymopterus globosus (Apiaceae), Crepis runcinata subsp. hallii (Asteraceae), Plagiobothrys parishii (Boraginaceae), Spartina gracilis (Poaceae), and Sphaeromeria potentilloides var. nitrophila (Asteraceae), and Tetradymia tetrameres (Asteraceae). Her goal is to systematically document the vascular flora of the region, publish a voucher-based checklist, and increase the overall understanding of this severely threatened ecosystem.
Mentzelia polita Decrypting phylogenetic placement and specific level relationships from a recent radiation for the CNPS listed rare plant Mentzelia polita (Loasaceae), with Dylan Cohen: The Mentzelia section Bartonia (Loasaceae) is the result of a rapid recent radiation throughout the Intermountain Ranges and deserts of the western United States. Mentzelia polita is taxonomically placed within section Bartonia and is listed by CNPS as 1B.2, rare or endangered in California and elsewhere. The ‘subshrubby' Bartonia clade includes M. polita and occurs primarily within the Mojave Desert. Historically this group has been challenging, with distinctions between taxa subtle at best. Problematic species include M. polita, M. oreophila, and M. leucophylla. Menztelia polita and M. oreophila both occur in California and Nevada, while M. oreophila ranges more widely. Both of the former taxa have been suggested to differ morphologically between their CA and NV populations. Furthermore, M. leucophylla is a federally listed endemic only found in Ash Meadows, NV, but has been suggested to occur in habitats similar to Ash Meadows within boarder California. Geographically, Ash Meadows is less than ten miles from the boarder of CA. Mentzelia leucophylla also has been confused historically with M. oreophila. Restriction Site Associated DNA Sequencing (RAD-Seq) is used to elucidate relationships among members of the Mentzelia section Bartonia ‘subshrubby' clade. Further considerations are given towards a conservation plan for ‘M. polita' within California.
No meetings in July and August: Summer break.
Caterpillar phacelia Thursday, September 27, 2018: Pot Luck Supper 6:30 p.m., MembersÃ¢ï¿½ï¿½ Slide Show 7:30 p.m., Poetry Reading and Art Show 8:15 p.m., Activity Survey and Award of Prizes 8:30 p.m.: Bring your favorite dish to share at the pot luck. To make this an earth-friendly event, please bring your own plates and utensils. The art show is an opportunity to share your favorite creative native-plant-related work — graphic art, paintings, poems, drawings, sculptures, photographs (print or digital), etc.
To participate in the slide show, please select one to twelve photos that you would like to share. If you can, please identify the plants in each photograph with common names and/or botanical names, or the group can help identify them. And please tell us where you found them. Submit digital image files, by Monday, September 24, to Katie Gallagher at email@example.com. Alternatively, especially if files are large (greater than 2 MB), you can send Katie a link to your preferred photo web site where she can download them, or you can upload the files using our web site’s upload page at https://cnps-sgm.org/upload. Files can be JPG or other image formats, preferably at full resolution. Or, if you prefer, you can create your own PowerPoint or OpenOffice slides and send them.
If you have original art works that you would like to share, please contact Gabi McLean at firstname.lastname@example.org to discuss arrangements.
The activity survey is an initiative to obtain feedback from members and supporters about new and enhanced activities being considered for the chapter. It covers a broad range of topics including collaboration with other organizations; field trips, outreach, and workshops; soocial media; natural gardening; the plant sale; community activities; action about invasive plants; and other subjects of interest.
Past programs of our chapter: See the Past Events page.
California Native Plant Week: California Native Plant Week is the third week of April. See the CNPS state web site for details.
Email notification: If you wish to be notified by email of upcoming field trips, please click here to subscribe to our email list.
Leaders: Each outing has one or more appointed leaders. It is not necessary to contact the leader beforehand in order to participate. All you need to do is turn up for the event.
Plant walks are held on the second Sunday of each month except July and August.
Meet inside Eaton Canyon Nature Center on the back patio at 9:00 a.m. Then go on a leisurely walk, about 2 hours, through the native plant garden that surronds the Center and into the nearby wild areas. The walk is different each time — what's leafing out, flowering, in seed, etc., determines what your leade will talk about — and different leaders bring drifferent points of view.

We sponsor outings on occasional dates throughout the year, usually on a Saturday. The walking ranges from easy, typically on wide fire roads, to moderately strenuous, such as on forest trails. If a convenient place is available nearby, we love to picnic afterward. Weather is unpredictable; snow, rain, fire and ice cancel.
Important note: The chapter does not advertise all field trips in the newsletter. Instead we have two levels of field trip, those with dates known well ahead to places expected to be good regardless of the season; and spur-of-the-moment trips organized with 1 to 2 weeks of notice, based on seasonal conditions and notified via this web site, email, and Facebook. This gives us more flexibility in finding wildflowers in bloom or fall color at its peak.
Past outings/field trips of our chapter: See the Past Events page.
None currently listed here: You may find relevant items on the state CNPS web site.
Our chapter becomes involved in projects from time to time. Some recent projects include:
