Both members and visitors are welcome at our regular monthly meetings, held at 7:30 p.m. on the fourth Thursday of each month except November and December. Meetings are held at Eaton Canyon Nature Center.

As of September 2022 our chapter gatherings are once again held in-person, and can be viewed simultaneously on Zoom. In line with current Los Angeles County recommendations, masks are strongly recommended for indoor public settings — but we especially welcome your in-person presence if you can.

As occurred previously, we plan that before long our meetings will be preceded from 7:00 to 7:30 p.m. by social time and informal plant identification.

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.

Current plant walks cancelled:  The plant walks usually held on the second Sunday of the month at 9 a.m. are currently cancelled.

Field outings and other chapter events for 2023

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.

Joshua Tree National Park
Sunday, April 2, 2023, to Friday, April 7, 2023: Joshua Tree National Park Camping Trip: Steve Hartman, CNPS Fellow, Past President, and desert plants specialist, is inviting CNPS members and native plant friends of Southern California CNPS chapters to this unique opportunity to explore and enjoy desert wildflowers at Joshua Tree National Park.  Reservations are required — details below. Here is Steve's invitation:

Dear Desert Wildflower Enthusiasts.

This year has already started for wildflowers in the California Desert. I have scheduled a CNPS field trip to Joshua Tree National Park, April 2-7, having reserved two group campsites at Cottonwood Springs. Campsite 1 will allow 7 vehicles. Campsite 2 will allow 11 vehicles. Only tent camping is allowed (recreational vehicles and habitable trailers are prohibited); however, you can sleep in your car or van.

You will still have to pay for a park pass (or use your senior pass) to get into the park.

Check in is noon on Sunday, April 2. Check out Friday, April 7 at noon.

You must reserve a spot to attend (see bottom). If all spots in the group campsite are taken, you could try to make a reservation for an individual campsite at Cottonwood Springs.

- Sunday, arrive, explore around campsite and Cottonwood Canyon.
- Monday, caravan to explore JTNP
- Tuesday, day hike from campsite to palm oasis.
- Wednesday, caravan to other sites in JTNP
- Thursday, hike to Pinto Dunes.
- Friday, pack up.  I’m trying to arrange a tour of the Mojave Desert Land Trust nursery on the way home on Friday.

Stay tuned!

South Pasadena Nature Park
Monthly volunteering at South Pasadena Nature Park: The South Pas Nature Park (officially the South Pasadena Arroyo Seco Woodland and Wildlife Park) is a four-acre habitat park along the Arroyo Seco in South Pasadena.

Each month volunteers weed and clean up in the park, and carry out improvement projects. Join us to meet your neighbors, enjoy the park, and make your community a better place.

Current volunteer Opportunities
Despite very little rain this winter, we had a modest display of wildflowers last spring. Throughout the pandemic period many people made good use of the park. The park lives on! And so regular development and maintenance continue! Please join us to remove litter and weeds, maintain paths, and enjoy the nature park with your neighbors. We are also working on a more welcoming and visible entrance (the Arroyo Entrance) from the recreational path that runs along the Arroyo Seco channel from Lohman Lane, along the golf course to the York Street bridge.
