Elsinore Peak and S. Main Divide Road – Mar 19
3-18 UPDATE: With the good rainfall this winter, this trip should be a good one.
Elsinore Peak is the southern most of the Santa Ana Mountain peaks and offers an unusual habitat of grasslands with some coastal sage scrub and chaparral. The area near the peak is further unique due to its volcanic history and unusual foundation of basalt rock. The specific stops for our visit will depend upon current conditions and the season’s unpredictable bloom, but we may explore the area just below the peak for spring wildflowers (Fritillaria biflora, Ranunculus, Goldfields, Alliums, Calochortus, Clarkia, Collinsia, Popcorn Flowers, Monkeyflowers, Lupines, Peonies, Sanicula and more). For a list of species seen in the Elsinore Peak vicinity, click here.
Afterward, we will almost certainly visit a site or two along S. Main Divide Road of the 2013 “Falls” fire. A couple of years ago, this was a highlight of Spring, with large displays of fire-following plants, including thousands of Fire poppies - Papaver californicum, Chorizanthe, Delphinium, Penstemons, Caulanthus, Emmenanthe, Lupinus and many others. It is interesting to see the succession of plants following this fire. Meet 8 AM at the parking lot at Bravo Burgers, 31722 Rancho Viejo Rd., San Juan Capistrano (just off Hwy 74 near Int. 5). Free and open to all. Bring trail shoes, hat, sunscreen, water and lunch if desired. Leader: Ron Vanderhoff. This trip does require a USFS Adventure Pass!
Free and open to all. Physical Difficulty: Moderate. No water or restrooms. Plant Intensity: Moderate to high, especially wildflowers. Time: Approx. 3 hours or more depending on the group.

Assisted by Nick Jensen, Rancho Santa Ana Botanic Garden, Claremont. Encompassing an area of 270,000 acres or 420 square miles, the Tejon Ranch occupies one of the most interesting and complex ecological areas in California. As a result of its unique position at the confluence of four floristic regions, Tejon Ranch is an area of ecological transitions, interesting assemblages of plants from seemingly disparate regions, and quite possibly a whole host of undescribed species, new to science.
As a private, working cattle ranch since the 1840s, Tejon Ranch was almost entirely closed to scientific research until 2008 when the Tejon Ranch Conservancy was created. Under this landmark deal, approximately 100,000 acres of the ranch were placed under conservation easements, and an additional 140,000 acres were reserved from the potential of future development. This amounts to approximately 90% of the ranch being conserved for future generations. As a result of the creation of the Tejon Ranch Conservancy, the ranch is now effectively “open” for scientific research.
Nick Jensen, of The Rancho Santa Ana Botanic Garden, will be our guide for this amazing botanical trip. The goal of Nick’s research at the ranch is to perform a floristic survey leading to a better understanding of the plants on the property and the adjacent ecological regions.
We will meet on the mornings of April 15 at 9 AM at the Tejon Ranch Conservancy offices at 1037 Bear Trap Rd. in Lebec (map to follow for registered attendees). We will then head out to the field for the day, focusing on whichever areas of the ranch Nick thinks are of interest at that time. On Sunday, we will finish up at approximately 2:30 PM.
There are many hotels/motels and restaurants in the Lebec area for those staying overnight. There is also a grassy area to car camp on the San Joaquin side of the ranch, with water and porta-potties available. No campfires. Please let us know if you intend to camp and we will provide additional details. Finally, there are no pets permitted on the ranch.
Physical Difficulty: moderate. Plant Intensity: High. Additional details will be sent to those that RSVP.
Trip will be limited to the first 19 people to RSVP to field. Please let us know if your plans change so we can add other people from the wait list. $40 fee collected will be used to support the Tejon Ranch Conservancy.

Bluff Lake & Onyx Summit, San Bernardino Mts. – June 11
The Big Bear area has a wealth of interesting plants that are unique to high elevations. This is a great area to visit in the summer after wildflowers in Orange County have faded from the heat. Bluff Lake, located at 7,600 ft, is a 20-acre lake and meadow, with majestic outcrops of quartz monzonite. The reserve includes an intact mountain marsh and meadow complex that contains federally threatened Bear Valley bluegrass (Poa atropurpurea), the federally endangered Big Bear Checkerbloom (Sidalcea pedata) and California dandelion (Taraxacum californicum). Botanically the meadow is remarkable, with 16 species of sedges (Carex), 8 species of wire grass (Juncus) and 14 species of native grass. Mature forests of lodgepole pine, Jeffrey pine, and white fir surround the meadow. Our second location, Onyx Summit, has some of the oldest Junipers in Southern California, along with 4 species of Pine. There will likely be an abundance of Buckwheat species. We may also take a side trip to check out the Baldwin Lake Ecological Reserve (the lake is currently dry).
We will meet at the Bluff Lake campground parking lot at 9 AM, explore the meadow and lake edges, have lunch, then visit the trail to Onyx Summit, which is just off the road on the return trip. This is an all-day trip. Some people may prefer to stay overnight at Big Bear. Limited water or restrooms. Bring hat, sunscreen, camera, notepad, water and hiking shoes/boots. A list of possible plants that we may see will be provided. Since many are not found in Orange County, this will be an exercise in plant identification. The drive time is approximately 2 to 2.5 hours one-way [Driving instructions to be provided]. Leader: Diane Etchison.
Free and open to all. Plant intensity: High. Physical Difficulty: Moderate. All day.
Bolsa Chica Marsh – Jun 18
Bolsa Chica is one of Orange County’s most significant open spaces, with a unique collection of habitats including sand dunes, salt marsh, coastal sage scrub, freshwater wetlands, riparian woodlands and native grasslands. The reserve is a dynamic ecosystem supporting not only a variety of interesting and highly adapted plants, but a large assortment of invertebrates, fish, birds (321 species) and other wildlife. Of course, non-native plants have been introduced into the ecology here and they will also be pointed out and discussed during our visit.
David Pryor, Senior Scientist with The Bolsa Chica Conservancy and retired CA State Parks biologist will lead this trip, which will approximately coincide with the publication of a new booklet, The Plants of Bolsa Chica.
We will walk the Loop Trail, which crosses a wooden bridge, passes two overlooks, and returns to the parking lot via a sand-dune trail paralleling PCH. However, at the half-way point we will divert a little and visit the edge of a riparian community and maybe the upper mesa area. Meet 9 am at the South Lot. This parking area is our starting point and is located on Pacific Coast Highway almost directly across PCH from the Bolsa Chica State Beach entrance. There is no charge for parking.

Goldenwest College Native Plant Garden – October 21
Join OC CNPS and Dan Songster for a fall tour and discussion of the extensive native garden at Golden West College. Conceived in the mid 1970’s, the garden really became established in the early 1990’s. The collection is one of Orange County’s best examples of the use of native plants in both ornamental and habitat style landscapes. Dan Songster, OC CNPS Chapter President, and a founder of the Golden West College Native Garden, will be our host and guide showing both the Garden’s successes and failures. The garden features over an acre of native plants and is divided into plant communities based upon soil and water requirements, and despite the predominance of heavy clay soils, thrives.
Examples of juvenile and mature plants are seen side by side (most fairly common and some rare), arranged in eight different habitats from throughout the state. The space also includes a greenhouse, a 30-seat amphitheater, and a water settling area. For more information about the garden including directions, check out http://www.goldenwestcollege.edu/garden/visiting/.
Leader: Dan Songster. We will meet at the garden entrance at 9AM. Due to the weekend swap meet in the parking lot nearest the garden, we will be parking at the north end of the Gothard Street Parking lot. Volunteers will walk you across the campus to the Garden itself.
Free and open to all. Physical difficulty: Easy. Plant Intensity: Moderate. Time: Approx. 2-3 hours.
Arroyo Trabuco from O/Neill Park – Nov 19

The “Other” Plants: Bryophytes of Harding Canyon – Jan 28
IMPORTANT NOTICE: This trip has changed location.
Hwy 74 is currently closed to all traffic in both directions. We will be visiting Harding Canyon instead. The start time remains at 9 AM.
We will head UP the Harding Truck Trail/Road, then drop down into Harding Canyon. The climb up is about .5 miles and the trail down is about 300-400 meters. There ARE wet spots. Hiking boots are best, but tennis shoes are possible. The trail in the canyon is rocky and rutted, so be prepared. You WILL get your feet wet, esp. if you decide to cross the creek, which is flowing strong. The scenery is great!
Meet at 9 AM at the trailhead, which is off the Ortega Highway (SR 74), 19.5 miles from the San Diego Freeway. Once in the parking lot we will meet on the east (right side), just across the road from the famous Candy Store. Parking here does require a USFS Adventure Pass! (more info.) We recommend that you purchase the pass in advance from Big 5, Sport Chalet, REI, or most large sports retailers, since the Candy Store will not be open when we arrive. Leader: Paul Wilson.
Free and open to all. Physical difficulty: Easy to Moderate. Limited water or restrooms. Bring hat, sunscreen, camera, notepad and water. A magnifying glass is highly recommended. Trip time: approximately three hours. Plant intensity: Medium to high.
Fossil Reef and Plants of Sheep Hills, Laguna Hills – Feb 12
FEB 11 FINAL UPDATE:
Directions were a bit confusing. We will meet at the end of Park Avenue, which is the street directly in front of Aliso-Viejo Middle School, which abuts Aliso-Viejo Community Park. The address is 111 Park Avenue, Aliso Viejo.
From Aliso Viejo Parkway, take Cedarbrook Road to the South and follow it about .75 miles until it deads ends in front of the school.
See you tomorrow! The ground will be wet from the rain, but the plants and area will be spectacular, although still rather "green" this early in the season. Tennis shows OK, but expect wet feet.
Fossil Reef is a very unique 17 million year old preserved portion of a formerly submerged tropical reef. It is a tropical shell reef associated with fossil rich beach sand. 48 species of fossil marine vertebrates have been recorded from here. Extending for six miles across the Saddleback Valley, this unusual limestone deposit is also found on the Palos Verdes Peninsula, San Clemente Island, Santa Catalina Island, and in Santa Barbara and San Luis Obispo Counties. The exposures here represent the ocean floor, as it existed 17 million years ago. The reef is unique, as it is part of an ancient sea floor that has been exposed by tectonic uplift and weathering processes. This uplift also formed the Santa Ana Mountains and the San Joaquin Hills. The marine muds, that later covered the limestone, contain plankton fossils, shark teeth, fish bones, marine mammal bones, and seaweed imprints – and a large baleen whale was collected nearby in 1981. Botanically, the unique geology and limestone soil supports Orange County’s only small colony of Astragalus pomonensis. We will search for plants in the unique area and see what we can turn up. Meet 9 AM on the street in front of Aliso Viejo Middle School, which is adjacent to Aliso Viejo Community Park. Google Maps works best as 1111 Park Avenue, Aliso Viejo. From there we will walk a short distance to the field trip/reef area. Leaders: Jonathan Frank and Ron Vanderhoff.
Free and open to all. Physical difficulty: Easy, with relatively short walking distances and easy terrain. Plant Intensity: Light. Time: Approx. 2 hours.
Harding Truck Trail – Feb 19

We are a bit early for heavy bloom, but we do have reports from several people of flowers at scatterred locations. We will follow those reports and decide on the specific stops in the morning. See you tomorrow! Bring snacks, water, a sack lunch and your enthusiasm.
Anza-Borrego is California’s largest State Park and is rich in botanical treasures, especially spring wildflowers. Desert bloom is always a very unpredictable thing, with blooms varying in timing, location and intensity every year and even from week to week. Please visit this site regularly for any date changes on this trip. Meet promptly at 6:30 am at Bravo Burger parking lot or meet at the Anza-Borrego Visitors Center at 9 am. The Visitor’s Center is located at 200 Palm Canyon Drive, Borrego Springs. $10 donation to OC CNPS requested. This will be a caravan-type trip, as we follow the bloom around the park. We will drive from location-to-location, usually parking along the shoulders of the road, according to where we get reports of the best bloom and plants. Each stop will provide ample time to explore, identify and photograph the flora.
Leaders: Diane Etchison and Rachel Whitt.
Free and open to all. Physical difficulty: Easy to moderate. Plant Intensity: Uncertain, depending upon the year. Time: All day.
Wildflower Showcase, Irvine Ranch Conservancy Seed Farm Open House – Mar 4, RSVP through IRC website
The Orange County Chapter of the California Native Plant Society, and the Irvine Ranch Conservancy invite you to join them from 10am-2pm as they celebrate Orange County native wildflowers at the Conservancy’s native seed farm. This event is a great way to learn more about OC CNPS, IRC, and the work each organization is doing to conserve, protect, and restore native wildflowers in Orange County. The 8-acre native seed farm currently grows 45 local plant species, each providing seed used to support ecological restoration locally. Expect many of them to be in full bloom for this event, which will be opened by brief presentations from OC CNPS and Conservancy staff, followed by a picnic lunch. After lunch, guests are invited to stroll the grounds at their own pace, or join a guided walking tour, on which they’ll learn about some of the amazing local flora being grown on the farm. OC CNPS will also be presenting on various local engagement opportunities, including information about field trips and their upcoming native garden tour. If you enjoy native wildflowers, good people, and outdoor fun, this event is for you! Parking is limited and carpooling is recommended. Please RSVP at www.letsgooutside.org.
Silverado Canyon & Maple Springs Truck Trail, after the Burn – Mar 12
UPDATE: The forest service gate will likely be closed, due to road conditions further down the way. However, it is a short walk to the edge of the former burn area. The weather looks great. See you Sunday.
Most everyone who enjoys the outdoors in Orange County also knows Silverado Canyon, one of the deepest and longest canyons in the Santa Ana Mountains. On this trip we will explore much of the area that was burned in a 1,600 acre fire during Sept. of 2014. Annuals wildflowers have been abundant here over the past two springs, but are now giving way to successional herbs and shrubs. From the base in Silverado Canyon, we will hike up the switchbacks of the old fire road as far as the group decides, perhaps all the way to Bedford Peak (3,800 feet) at about 3.5 miles with a 1,900 foot elevation gain. Along the way, expect to see early spring wildflowers such as Phacelia, Eucrypta, Lupinus, etc. Also expect an abundance of showy Penstemon and bush poppy (Dendromecon rigida) towards the end of our hike.
Meet 8 am at the large Forest Service gate at the far end of Silverado Canyon Road. (5.75 miles off Santiago Cyn. Rd.). Leader: Jonathan Frank.
Free and open to all. This trip does require a USFS Adventure Pass! (more info.) Physical Difficulty: Strenuous. Plant Intensity: Medium. Time: 3-5 hours.
Baker Canyon, Irvine Ranch Natural Landmarks – Fri, Mar 17, RSVP through IRC website
A Friday trip! Between Silverado Canyon and Black Star Canyon, Baker Canyon is a very special place, well insulated and protected from much of the outside world. A part of the Irvine Ranch Natural Landmark, it is off limits to most public access, except for a few days each year, so this is a special opportunity to explore an excellent natural area with other like-minded people. Enjoy views of the Santa Ana Mountains, as well the wildflowers and plants of oak-shaded Baker Canyon and the ridges above as you learn why so many different plants and animals call this place home. Plants that may be blooming at this time of year include 3 types of Ceanothus, Fritillaria biflora (Chocolate Lily) and Harpagonella palmeri (Palmer's Grapplinghook). This will be a 3-4 mile loop hike beginning with a gradual climb to a final elevation of 1370 ft. (elevation gain about 460 ft.), with beautiful views at the top. This event requires reservations made through the IRC website: http://letsgooutside.org/. Check the website 1-2 months prior to the event to book your reservation. There is a cap on the number of participants, first come-first serve. Leader: Diane Etchison.
