Activities

SPEAKERS/PROGRAMS AT FORTHCOMING CHAPTER MEETINGS

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.


Inyo Mountains
Thursday, February 27, 2020, 7:30 p.,m.:Talks by two of our 2019 grant recipients: This month we have two 20-minute talks from two CNPS San Gabriel Mountains Chapter 2019 grant recipients.

Maria Jesus is a master’s student at Rancho Santa Ana Botanic Garden/Claremont Graduate University. Previously, Maria managed a multi-agency vegetation monitoring program aimed at informing adaptive management of public lands in California and Nevada. She is committed to the advancement of native plant conservation, mentoring emerging botanists, and increasing public support and understanding of plant science.

Glen Morrison began his scientific education at Citrus Community College, in Glendora, California, where he first was involved in field biology and botanical research, before transferring to Cal Poly Pomona to complete his bachelor's degree. As an undergraduate, Glen fell in love with botany, exploring the flora of the San Gabriel Mountains, and found research experiences at Rancho Santa Ana Botanic Garden, Cal Poly Pomona, and UC Riverside on a diverse range of botanical topics. He is now in the third year of his PhD in the Plant Biology graduate program at UC Riverside, where he works with Amy Litt, applying new methods to evaluate the distinctiveness of currently recognized species and subspecies in the most species-diverse woody genus in the California flora, the manzanitas (Arctostaphylos Adans.). After graduating from his PhD, Glen plans to pursue a career as an educator and researcher.


Hesperidanthus jaegeri
Floristic exploration in the land that time forgot: A vascular flora of the southern Inyo Mountains, Inyo County, CA, with Maria Jesus: The Inyo Mountains in Inyo County, California, are an important plant area where the Great Basin and Mojave Deserts meet. This area was once home to several thriving mining towns, but today is rarely traveled. Despite high numbers of endemic species, the southern portion of this mountain range is nearly roadless and remains botanically underexplored. Here, one is more likely to encounter a mining artifact or relictual plant species than another person. Mining may return to this important plant area which is currently under threat by an exploratory gold mining project. My floristic research in this area establishes baseline data that will help stakeholders better understand the potential impacts of a mining project and garner public support in favor of conservation. In this presentation, I will share preliminary results of my floristic research, including new occurrences of rare taxa and an update on the status of the Conglomerate Mesa drilling project


Eastwood manzanita resprouting after fire
Studies in Eastwood manzanita, Arctostaphylos glandulosa, with Glen Morrison: Delimiting biodiversity units is difficult in organisms in which differentiation is obscured by hybridization, plasticity, and other factors that blur phenotypic boundaries. Such work is more complicated when the focal units are subspecies, the definition of which has not been broadly explored in the era of modern genetic methods. Eastwood manzanita (Arctostaphylos glandulosa Eastw.), is a widely distributed and morphologically complex chaparral shrub species with much subspecific variation that has proven challenging to categorize. Currently ten subspecies are recognized, however, many of them are not geographically segregated, and morphological intermediates are common. Subspecies delimitation is of particular importance in this species, as two of the subspecies are rare. In this study, we applied an evolutionary definition of subspecies, reduced-representation genome sequencing, and environmental data, to evaluate differentiation within Eastwood manzanita. Our analyses did not show genetic differentiation among subspecies of Eastwood manzanita, with the exception of one of the two rare subspecies, San Gabriel manzanita (A. glandulosa subsp. gabrielensis). We present further exploration of the genetic distinction of San Gabriel manzanita, and use our sequence data to evaluate an existing hypothesis that San Gabriel manzanita may be of hybrid origin between A. glandulosa and a second species, A. parryana.

Large flowered phacelia
Thursday, March 26, 2020 , 7:30 p.m.: Fire-safe landscaping, with Orchid Black: Learn how to create and maintain a beautiful fire-safe home and landscape through case studies that illustrate simple principles and best practices that may help your property survive a wildfile.

Orchid Black is a garden designer who has served on the Board of the California Native Plant Society, and also as Chair of the CNPS Chapter Council. She is a former president of our CNPS chapter, San Gabriel Mountains.

OUTINGS, FIELD TRIPS, AND OTHER EVENTS OF OUR CHAPTER & CNPS

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.

Eaton Canyon Plant Walks

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.

Field outings for 2020

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.


A liverwort (Riccia sp.)
Saturday, March 21, 2020, 8 a.m. - 12 noon: Bryophyte walk at Santa Fe Dam: Grade: Easy. Leader: Paul Wilson.

This outing addresses the question: What are bryophytes and why are they important?  During the walk Paul will give an introduction to bryophytes, and provide a guide to the liverworts and mosses seen along the track. We will definitely see liverworts (like the Riccia in the photo), which are abundant in this never-destroyed vegetation type and that are very slow to return following restoration. Also likely to be seen are winter ephemerals (like Pleuridium), which grow from almost nothing to having mature spores during our wet season. And we might see other more perennial mosses (like Rosulabryum) and perhaps even leafy liverworts (like Porella). Vascular plants will be enjoyed in between the non-vascular delights.

Paul Wilson is a long-time enthusiast of bryophytes, and initiated the CNPS Bryophyte Chapter. He is a Professor of Biology at California State University Northridge.

Directions: Take the 210 Fwy to the Irwindale Ave off-ramp. Travel south on Irwindale Ave to Arrow Hwy, then turn west to the Santa Fe Dam entrance drive on the right. After the stop at the entrance kiosk (fee $10 per car) turn right (north), following signs to the Nature Center, where we will meet at 8 a.m. Wear good sturdy shoes or boots, hat, and bring water. Rain will cancel the outing. To receive updates, contact paulsiriwilson@gmail.com.
