The LA County Board of Supervisors will consider whether or not to approve the proposed Centennial development next Tuesday, December 11.
Although this project is located in LA County, we believe this is an issue that impacts all of California, both in terms of our biodiversity and the precedent it sets for sprawl at the Wildland Urban Interface. Tejon Ranch is one of the most biodiverse areas of California, containing 14% of California’s native flora and a third of our native oaks. What’s more, it’s situated in a high fire hazard severity zone, putting future residents in harm’s way. We are advocating for the conservation of this land in its entirety.
Bill Deneen, long time CNPS member, Hoover Awardee, and champion of the Guadalupe-Nipomo Dunes died at the age of 93 in September. Bill taught biology at Santa Maria High School for 25 years, during which time he became a passionate advocate for the environment. He worked with Kathleen Goddard Jones and others to keep a nuclear power plant from being built in the Nipomo Dunes, which he loved with a deep passion. Later he was arrested from ‘crossing the blue line’ at protests against the re-siting of the power plant at Diablo Canyon, earning him the title of ‘ecohooligan’ which he wore proudly for the rest of his life. In recent years he opposed the use of OHVs in the dunes, and was on the enemies list of the local OHV community. He founded an Environmental Award which he gave out to encourage conservation action, and in a touching moment in his failing last years was given his own award by his admirers. In a sort-of-goodbye party in 2015 held at the Dana Cultural Center, he received accolades from friends and family to notable politicians like then-Assemblyman Katcho Achadjian and Congresswoman Lois Capps. Capps called Bill a ‘national treasure’. Older members of the chapter will remember the many field trips he led into the dunes, and his fierce sense of humor. Bill… we will miss you… and thanks.
You have probably wandered the nursery isles looking for the ever more popular native plants being sold. Do you ever consider how those plants have been propagated? Many, if not most, native plants in the nursery trade are propagated by cuttings. The nursery person knows what the plant will look like and behave like. And (more…)

There is a weed removal initiative underway called the South Central Coast Invasive Species Eradication Project. Funded by the Wildlife Conservation Board and matching partners the $600K project joins CalIPC with multiple partners in a merged region of San Luis Obispo County and Santa Barbara County with help from the Weed Management Area of San Luis Obispo County. This effort is targeting weeds with a realistic chance of eradicating 95% of their populations in five years.
The sea lavenders are at threat to Cordlylanthus maritimus ssp. maritimus – salt marsh bird’s beak and Suaeda californica -California seablite. They have appeared along the boardwalk in Morro Bay State Park In the Guadalupe-Nipomo Dunes. Russian wheatgrass can take over areas that are habitat for Atriplex leucophylla – Saltbush, Beach-Bur, Red Sand-Verbena and Dunedelion.
The agencies eradicating the weeds will track their progress through CalWeedMapper that CalIPC arranged. Partners will meet annually to report on progress.

The cover drawing and article for this issue of the OBISPOENSIS was written and drawn by Alice Meyer. She was a very active member (and first Hoover Award Recipient in the 1970 and 80’s. She is the one who named our newsletter, OBISPOENSIS, and served as its editor (and typist) for the many years. She is also responsible for setting up the first successful chapter plant sales as well as recruiting our current Plant Sale Chair. She didn’t restrict herself to CNPS. She was also active in the Morro Bay Audubon to which she submitted a number of articles entitled “MEET A NATIVE PLANT’. Below is one of those articles. It was chosen since milkweeds are so important in the conservation of the Monarch butterfly and is being encouraged as a garden plant. Members of this genus serve as the primary food source for Monarch butterfly larva. While eating the milkweed leaves, the larva incorporate the milkweed toxins into their bodies and its these milkweed toxins that protect the Monarch larva from most predators.
I do need to mention a taxonomic update. In her first paragraph Alice places the milkweeds in the taxonomic family, Asclepiadaceae. This was where it was placed up until the 1990’s. Today the two families of milky sapped species [milkweeds (Asclepias) and dogbanes (Apocynum)] have been combined into the single family, Apocynaceae. Milkweeds are primarily temperate in distribution while the dogbane relatives are primarily tropical. Classical taxonomic work always accepted these two families as very closely related. Modern taxonomic studies (including DNA work) have discover the relationships to be intertwined which required their unification into a single family. A number of these formally separated but closely related families have now been combined.
MEET A NATIVE PLANT Asclepias eriocarpus
Milkweed is a perennial plant of the milkweed family (Asclepidiaceae) family. The species shown is common in the Coast Ranges, Sierra Foothills south to Coastal Southern California from 100 to 2000 ft. The species shown is Asclepias eriocarpa (as-KLEP-i-as aor-ee-CARP-a). Monarch butterflies lay their eggs on this plant. The plants are erect and sturdy from 18-36” tall, with leaves 3-4” long, in whorls of 3 or 4 leaves. These are covered with fine hairs, which make them look and feel like flannel. Stems and leaves contain a milky juice, a form of latex.
The clusters of flowers appear in May at the ends of stems between the leaves. The structure of the flowers is very unusual. The corolla is cut into 5 petals. These are turned down so the hide the calyx. The stamens stalks are joined into a tube and the five ‘hoods’ are attached to the base of the column; this is the ‘crown’ of corona, and in this species the crown is pink or purplish. It is actually the nectary of the flower. The flower and its stem is creamy white. In the center of the flower is a fleshy column or tube formed by the stalks of the stamens, capped by the stigma, hiding the two tubes of styles leading down to the ovaries.
The pollen in each anther-cell is a waxy mass of different anthers and adjacent masses of different anthers are attached to a cleft gland. This resembles tiny saddle-bags, clipped together, and if a bee catches her foot in the cleft she may pull out and fly away with two pollen masses to fertilize another flower. To do this, she must get her foot caught in the cleft of another flower.
The probabilities of a bee catching a foot in the cleft of two different flowers, first to collect the pollen sacs, then to deposit them in another flower is so remote that this is called ‘lottery pollination’. When a flower is pollinated its stem enlarges and the petals fall off. The calyx remains at the base of the downy seed pod which becomes 3 to 4” long and the remains of the hoods hang on to the tip of the pod for time. When the pod is ripe, and dry, it splits lengthwise, revealing neat rows of seeds, each with a parachute of fine hairs attached. As soon as the these hairs are dry, the seeds will fly away on the wind to be dispersed. Flowers that have not been pollinated along with their stems, wither and fall away.

On July 15, 2015, Governor Jerry Brown signed the bill designating lace lichen, Ramalina menziesii, the California State Lichen.
The law takes effect January 1, 2016, making California the first state to recognize a lichen as a state symbol. Lace lichen joins the California poppy as the state flower and the grizzly bear as the state animal.
The California Lichen Society promotes the appreciation, conservation, and study of California lichens, and has posted a beautiful article about our new state lichen on their website: http://californialichens.org/state-lichen/
CALS sees this designation as an important step in increasing public awareness of the significant roles that lichens play in our natural environment. Calling attention to lichens by recognizing one of them as the California State Lichen creates an opportunity for us to learn about and celebrate the things that make California special.
