CNPS is Hiring an Associate Director
As you may have heard, CNPS is hiring an Associate Director. Please help us get the word out to ﬁnd someone special who will help continue the great momentum we’ve built. Due to the great response so far, the hiring committee will begin reviewing applications early this month, so potential candidates should apply as soon as possible.
The Associate Director (AD) is a new leadership position. Under the direction of the Executive Director, the AD manages and enhances internal organization processes and infrastructure to ensure smooth and seamless operations that support CNPS’s ability to fulfill its mission. In the absence of the Executive Director, the AD assumes responsibility for directing the day to day operations of CNPS.
The AD provides key strategic leadership to the Executive Director (ED) by advising on issues of significant organizational importance and long-term sustainability. The AD is responsible for overseeing and monitoring financial practices, leading the budgeting process, managing human resources, and providing oversight of facilities and IT infrastructure. They will have broad latitude to shape this growing organization, including defining strategy and scoping/hiring new positions to help fulfill these important responsibilities. For the right person, one who sees how Californians can work together to celebrate and save our flora, this is a rare opportunity to make an enduring difference.

Conservation Committee Update
November was quiet as far as specific projects up for CNPS review, but there are several conservation issues growing in the background that will require our wary eye.
Price Canyon Trail (Proposed)
I attended and gave input to a scoping meeting for a proposed trail through Price Canyon from Edna to Pismo Beach. This will be a section of the bi-state Anza Trail, and would have to pass through the Arroyo Grande Oil Field. I commented against sections of trail that went through relatively undisturbed oak woodland and the habitat of Pismo clarkia rather than staying in areas that are currently disturbed. I find that there is a conflict between potential trail users wanting a pleasant “nature experience” and the need of nature to avoid the “human experience” as much as possible. The SLO Council of Governments are taking the lead, and at this time there is no money for any trail development and right-of-way issues are significant.
It is possible that the rampant development that has destroyed much of the older dune surfaces of the Nipomo Mesa might slow, due to newly revealed issues associated with water supply. The Northern Cities Management Area (basically the Five Cities minus Avila) are challenging Nipomo CSD’s continued issuance of building permits on the basis that the CSD is intercepting groundwater that would normally percolate from the Santa Maria valley toward the NCMA. Recently water tables in the area are dropping to the extent that sea water intrusion is a distinct possibility.
Veldt Grass Impact
A circa 1970 photo of the Nipomo Mesa oil refinery reveals the eucalyptus groves since removed for the Woodlands Development and the once vibrant dune scrub community seen above and below the tank farm. The area above the tank farm was the pride of the ‘Dune Mother’, Kathleen Goddard Jones, who called it Wild Almond Meadows. Dark dune shrubs cover the land in 1970 (left), almost vanished in the Google Earth 2013 image (right) due to competition with veldt grass and attempts to control it using livestock.
The following is an article from February 1993. It was chosen by the editor to spare me the choice since Bonnie and I were away in late October. We totally agree with his choice; we had totally forgotten about it. The repeat of this article reminds me that many species of oaks have been producing fewer and fewer offspring primarily due to habitat modiﬁcation and outright habitat loss. They are also probably being impacted by rising temperatures due to global climate change. It is also important to remember that oaks have been extremely important in the history of the human race. Various oak species have provided food, cork, charcoal, and lumber. A few species still do.
Dried Leaf Retention in Black Oaks
The idea for the cover was hatched out of a statement made by Bonnie while we were traveling to Yosemite Valley just before Christmas. She remarked that the dry, brown leaves and black trucks of the Sierra black oak (Quercus kelloggii) made a beautiful counterpoint to the white snow. This got me to thinking about the advantages that might accrue to a tree to keep its old, dead, dry leaves until spring of the following year. I had noticed this same phenomenon ﬁrst in the eastern black oak of my youth in Illinois (Quercus nigra). Two ideas came readily to mind. First, it might provide some advantage to the plant that would aid its survival in the Montane Mixed Coniferous Forest where the Sierra black oak most often occurs. Some herbaceous plants produce hard leaves (e.g., bracken fern, Pteridium aquilinum) that last through the winter; these have been shown to shade out seedlings of competing plants during early spring growth. Last season’s bracken leaves begin to break down shortly after the new, young shoots get a foot or so tall. However, it is hard for me to accept a similar explanation to account for trees retaining dead leaves. I can think of a number of disadvantages such as increasing wind resistance and holding more snow on the branches. Both should result in more broken branches.
Retaining dead leaves could merely be an artifact of its history. Its closest relatives are all evergreen oaks and include the island scrub oak (Q. parvula) and the coast and interior live oaks (Q. agrifolia and Q. wislizeni). This group of oaks is called the red or black oak group (Erythrobalanus) and differs from the other major group, the white oaks (Lepidobalanus), primarily by having the leaf veins extending beyond the margin of the leaf as fairly heavy, tawny bristles or spines, possessing dark gray to blackish smooth bark, having thin ﬂat acorn scales, generally taking two years to mature their acorn (exception the coast live oak) and having reddish-brown wood.
A third group of oaks is also found in California and these possess characters in combinations not found in the two major groups. All three groups include species of evergreen and deciduous oaks, but, as far as I know, only the deciduous black oaks retain many of their dead leaves for so long a time period.
Could it merely be a trait indicating a relatively recent origin of deciduous habit from the more general evergreen habit of the group? If my memory serves me right, both eastern and Sierran black oak leaves seem thicker and more leathery than one would expect for a deciduous tree.
What about the advantage of ﬂowering trees and shrubs from evergreen habit? Primarily it is due to the fact that the off season (cold and/or dry) is not always so cold and/ or dry as to preclude a leaf from functioning. There are short periods, even in the most severe of seasons, when conditions are favorable for metabolism and growth. Evergreen plants can take advantage of these short periods because their leaves are in place, whereas deciduous trees must forgo them since, by the time they could produce new leaves, the favorable period would have been long gone.
Of course, evergreen plants must pay the cost of maintaining and protecting these living leaves during times when conditions prevent them from functioning, a cost not required of deciduous trees and shrubs. In other words, whether a ﬂowering tree or shrub is evergreen or deciduous depends on the balance between cost of maintaining non-functional leaves versus the gain from being able to take advantage of short periods of moderate conditions. Thus, evergreen ﬂowering trees and shrubs tend toward coastal and/or low to mid elevations where severe conditions tend to be rare and of short duration. Evergreen conifers, on the other hand, are a different story which will have wait for another time.

Great News! Fall is here and the rains have ﬁnally started. There are so many things we could discuss this month but I would like to focus on how to prepare for what could be a very wet winter.
Manage erosion on slopes
Covering slopes with mulch would be a good idea. There are basically two types of mulch out there. Some let rain water penetrate such as fresh tree chips, recycled wood chips, and walk on bark. Other mulches such as gorilla hair or cedar bark, hold water tightly and do not allow it to penetrate, hence stopping soil erosion. Just remember, if you have plants on a steep slope, remove gorilla hair two feet from around the plants’ trunks. This will allow rainwater to penetrate the area and water the plants’ roots. If your plans are to suppress weed growth on a level area, apply any other mulch four inches thick. It is not necessary to use gorilla hair. Remember to keep chips one foot away from trucks to prevent root rot.
Control water molds and root fungi
There’s a higher likelihood of having water borne pathogens affect drought-stricken plants during rainy months. These pathogens are easily spread by excess water so it’s important to remember that pooling water can spread a pathogen from a sick plant to a healthy one. If you have any plants that appear to be dying from drought stress, you would be wise to not allow water to run or pool there. Come spring, if the plant appears to be completely dead remove it immediately. If green growth appears, wait and see if it recovers.
Prune for high winds
Winter storms usually bring quite a bit of wind. A tree’s or shrub’s branches must allow the wind to pass threw or it will blow over. If you have any plants in need of thinning, fall is a great time . The nights have gotten cooler and plants are starting to go dormant. Consult gardening books for tips on how to thin your trees and shrubs. The goal is to allow wind to penetrate and blow threw the branches without destroying the general shape of your tree or shrub.
From Suzette and me, thanks to all of you who came and volunteered at this year’s plant sale. We had a great time and we really appreciated your help. Until I see you at our next meeting, Happy Gardening!

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.
We Encourage Your Input at our Next Board Meeting
The Board of Directors of the CNPS San Luis Obispo Chapter will hold its bi-monthly meeting on November 19th, 2015 from 6:00 to 7:30 pm.
This meeting is held in the Pavilion at the San Luis Obispo Botanical Garden, 3450 Dairy Creek Rd, SLO (located in Choro Regional Park across Hwy 1 from Cuesta College).
CNPS members are encouraged to attend the meeting to observe discussions and give input.
As one drives around in September, brilliant yellows, cheerful whites, subtle pinks, and even chartreuse greet us from bushes and roadsides. Except for the bright red leaves on Poison Oak, Toxicodendron diversilobium, few of our lower elevation natives have the brilliant red, orange, and yellow leaves that festoon mountains and eastern areas, yet many of our fall ﬂowers and leaves have their own unique if subtle charm. This is when our fall-blooming DYC’s come into their own.
Even the lowly Coyote Brush, Baccharis pilularis, one of the few dioecious, shrubby, non-showy composites that I know of, has its “Fifteen minutes (or 1-2 months) of fame.” The subtle yellow staminate ﬂowers of the male plant, aka “Mr. Fuzzy-Wuzzy,” shine with pride, and are quite fragrant, especially in bright sunshine.
The white, powder-puff plumes and smaller blossoms of the female plants, aka “Mrs. Fuzzy-Wuzzy,” greet those who have the eyes to see them. This is indeed the season of yellow ﬂowers. Prominent are the “diaspora” members of the Haplopappus genus, i.e., the various Golden Bushes, Hazardia, Ericameria, and Isocoma spp. The Mock Heather, Ericameria ericoides, looks as if its tops were spray painted. The tarweeds, Hemizonia, Centromadia, Deinandra, and Madia spp., Rabbit Brushes, Ericameria and Chrysothamnus spp., Goldenrods, Solidago spp., and Telegraph Weed, Heterotheca grandifolia, also greet the viewer.
White is represented by both ﬂowers and plumes. Various Lessingia spp. bloom in the fall including one appearing late enough to be known as the “Christmas Daisy.” A few late-blooming Buckwheats, Eriogonum spp., Morning Glories, Calystegia spp., and Mexican Elderberries, Sambucus mexicana, are evident. The Dandelion-like plumes of the composites, the pheasant feather-like plumes of the Western Mountain Mahogany, Cercocarpus betuloides, and the ﬂuffy plumes of the Cottonwoods, Populus spp., also liven the fall vegetation.
Pink is seen in the Twiggy and other Wreath Plants, Stephanomeria spp., maturing Buckwheats, Eriogonum spp., and the ubiquitous Naked Ladies, Amaryllis belladonna. But chartreuse? This is found in the rare but, in places, locally abundant Seaside Birdsbeak, Cordylanthus rigidus ssp. littoralis. A spectacular display can be seen on State Route 1 between Vandenberg Village and Allan Hancock College, where Deer Creek crosses the highway. Ah yes, beauty is in the eye of the beholder.
As plant lovers we should not only see our subtle fall beauty, but should be sharing this vision with others. Check Field Trips for our mid-October Burton Mesa Chaparral tour at the La Purisima Mission.

October was, thank goodness, another quiet month as far as development project review was concerned.
I attended and gave input to in what appeared to be an interesting project being conducted by the Corps of Engineers concerning coast erosion and beach sand management along the coast, and supposedly issues such as rising sea level. This is being performed on behalf of the SLO Council of Governments. My disappointment cannot be overstated. I was present at scoping meetings a year ago, and now find a year later that they have paid no attention to the effects of rising sea level on habitat and people around Morro Bay, and when I asked about their consultation with the National Estuary Program, their people didn’t even know we had such a program, or that the Corps did studies on sedimentation in Morro Bay. In their economic evaluation they considered only the economic value of beach attendance by the public and not erosion and stuff like the possible long-term risk to coastal properties. No wonder New Orleans flooded.
In other water related issues, the continued downward trends on the elevation of the groundwater surface along the coast south of Pismo Beach may be close to putting the groundwater- supported coastal lakes such as Black Lake at risk. The once-impressive peat wetlands of Black Lake Canyon just east of Highway 1 were drained and destroyed in the 1980s as springs dried up, and now the fate of the other wetlands is in question. I mention this as water use in the Nipomo Mesa area and the allocation of groundwater is becoming the subject of litigation between water management agencies.
Native Plants in the Landscape – Cultivating the natural beauty of the Central Coast
This is a photographic tour of California Native Plant use in the landscapes of Madrone Landscapes over the last 38 years.
Madrone Landscapes has been designing, installing and maintaining gardens throughout San Luis Obispo County, emphasizing California Native plant use, since 1977. Rick Mathews is founder and president of Madrone Landscapes, Design-Build Maintenance ﬁrm, based in Atascadero.
As a landscape contractor for nearly four decades, Mathews has incorporated the use of California native plants since the 1970s. The wisdom of this approach has repeatedly become apparent, through several drought cycles. Madrone continues to favor natives in their designs, as this presentation will convey.
Thursday, November 5, 2015, 7:00 p.m. Meet at the Veterans Hall, 801 Grand Avenue, San Luis Obispo.

Drawing by Bonnie and article by Dr. Malcolm McLeod below appeared in the November, 1991 Obispoensis.
When you read it you will see lots of similarities with our current drought situation as well as the much hoped for possibilities of an excellent rain year. Yea, el Niño! If we get the rain, we just may have a once a decade or so treat to witness. We can only hope. Malcolm was a long-time member of our chapter who served several years as out chapter president. He served many years as our rare plant coordinator. Malcolm mentions many names of people who came to see this rare event. They are a whose who of local last generation including naturalist-rancher Eben McMillan and botanists Clare Hardham and Clifton Smith. In 1991, the Carrizo Plains area was not yet a National Monument but a Natural Area administered by the Bureau of Land Management and the Nature Conservancy. It’s the presence of this species, as well as number of other plant and animal species, that aided in it being designated a National Monument in 2001 by President Bill Clinton.

Dear SLO rare plant enthusiast:
SLO County will have a visitor from the CNPS state office, Mona Robison. She was recently hired by CNPS to coordinate the State’s Rare Plant program (see attachment). Prior to CNPS, Mona has had a rich and diverse involvement with CA native plants. (more…)
Earlier this year, SLO city officials approached CNPS with the idea of restoring the deteriorated riparian habitat, which runs through the downtown adjacent to the Mission Plaza, with California native species. Our local chapter has embraced this project with great enthusiasm. (more…)
