The N-Judah, #6, #43, and #66 lines stop within 2 blocks.Before our programs, we take our speakers to dinner at Chang�s Kitchen, 1030 Irving Street,between 11th and 12th Avenues. Join us for good Chinese food and interesting conversation.Meet at the restaurant at 5:30 pm. RSVP appreciated but not required. If you wish to notify, pleasecall Jake Sigg at 415-731-3028.

SEPTEMBER 1, THURSDAY, 7:30 PMCamera Trapping California: Wildlife Study Stories From Across the Golden StateSpeaker: Ken Hickman; naturalist, camera trapper, wildlife researcherWhat are camera traps? These are sensor-triggered cameras that can last in the field for monthsand "digitally trap," i.e. photograph, the local wildlife.These capabilities are making them a go-totool for remote wildlife monitoring and surveying, while also creating new opportunities for wildliferesearch and educational outreach.In his talk, Ken will introduce the key concepts of camera trapping, and show its value as a wildliferesearch and monitoring method by taking us on a photographic tour of the animals, habitats, andeven a few plants, captured at his study sites across California which include Santa Cruz Mountains,Yuba Pass, Mono County, and the Carrizo Plain. You'll see badgers, burrowing owls, kangaroorats, kit foxes, pika, pygmy rabbits, mountain lions and mountain beavers. They are all presentedwith a sprinkling of the local plants and communities that they inhabit, hunt, and forage.Ken Hickman has a B.S. in physics from UC Santa Barbara with 20 years of experience in technologyand software. For the last 6 years he has been building homemade, high-quality camera traps foruse in wildlife studies and workshops with leading researchers, agencies and private land holdersin California. His cams have captured over 150 species of mammals and birds.

OCTOBER 6, THURSDAY, 7:30 PMPlanting a Wildlife and Pollinator Friendly Native GardenSpeaker: Don Mahoney, Ph.D.This program, presented with live material, will emphasize native plants that have proven to attractbutterflies and bees. Plants for butterfly larvae will be covered as well as plants for birds. Thebest times and techniques for planting will also be covered.Don Mahoney was born and raised in Nebraska and moved to California to attend the Universityof California at Berkeley, where he received a Ph.D.in 1984 in Wildland Resource Science. He has

worked at the Botanical Garden in San Francisco since that time and is currently Curator Emeritus in the process of retiring. He hastaught many classes on native plants over the years.

NOVEMBER 3, THURSDAY, 7:30 PMIsla de Cedros in Baja California: A Pacific IslandSpeaker: Michael UhlerLocated at the southernmost edge of the California Floristic Province, Isla de Cedros is an intriguing, wild, and beautiful island. Onthe highest points of this island persistent fog creates conditions suitable for plant speciesthat might otherwise be found much further north, where the annual rainfall amountsare significantly greater. Please join him on a pictorial journey of his latest visit toHuamalaguaor �The Island of Fogs.�Michael has been at the Regional Parks Botanic Garden, also known as �Tilden,� foreleven years. During this time he has been intrigued with plant biogeography andhas made many trips to the southernmost Pacific Islands of Baja California,Mexico to experience the land, the flora and fauna, and learn aboutthe people of this beautiful country and island.

SEPTEMBER 24, SATURDAY, 10 am � 12:30 pmGlen Canyon SpidersLeader: Darrell UbickSpiders are ubiquitous, but are usually hidden and hard to see.Fall is an especially good time to look, as the large orb weavers(family Araneidae) are almost certainly visible. At this time ofyear they are fully grown and females are ready to lay their eggs.Join Darrell Ubick, arachnologist at the California Academy ofSciences, to search for members of the genus Araneus, knownas pumpkin or shamrock spiders; Argiope, the garden spiders,whose webs have a striking zigzag pattern running top to bottom;and others. Meet behind the Glen Park Recreation Center wherethe lawn stops and the wild part of the canyon starts. This willbe an easy walk and is recommended for all ages. Contact: GailWechsler, wechslerifolia@gmail.com.

OCTOBER 8, SATURDAY, 10 am � 1 pmSan Bruno Mountain: Dairy Ravine and Cable RavineLeader: Doug AllshouseThese two north-facing ravines occupy most of the slope acrossfrom the main park entrance. Their names are tip-offs to theMountain�s past and present. The coastal scrub plant communities

here provide habitat for endangered butterflies despite the threatposed by eucalyptus plantings. From the Eucalyptus Loop we�llgo up the Dairy Ravine Trail to the Summit Loop and proceedto Kamchatka Point to look at two manzanitas, Arctostaphylosimbricata and A. uva-ursi forma suborbiculata, plus twohuckleberries, Vaccinium ovatum and a rare coastal occurrence ofV. cespitosum. Then it�s back down the Summit Loop above CableRavine to our starting point. Weather on the mountain is a boxof chocolates, so bring layers. Heavy rain postpones toOctober 22, and heavy rain on the 22nd cancels. Pay thefee ($6 per vehicle) at the entrance, then turn right at the stopsign, follow the road under Guadalupe Canyon Parkway, andmeet in the small parking area. Questions? Email Doug atdougsr228@comcast.net, or call or text him at 415-269-9967.

DECEMBER 3, SATURDAY, 11 am � 3:30 pmMontara Mountain Manzanitas in FallLeader: Mike VaseyWe return to Montara Mountain to round out four seasons ofobserving manzanitas in a coastal chaparral plant community,this time with mature fruit to help us distinguish between species.We also expect to see the inflorescences that have been on holdfor months in an immature state finally blooming or about tobloom. Mike Vasey is a coauthor of the excellent Field Guide toManzanitas, available at store.cnps.org. Serious rain willpostpone this trip to December 10.

The Yerba Buena Native Plant Saleis an opportunity to find a great many native plant species thataren�t readily available at garden centers. Our focus and offerings,as always, will be native plants local to our chapter area: SanFrancisco and northern San Mateo County, including Montara andSan Bruno Mountains. These are the species already adapted toour area�s climate, soils, and habitats--and are also important toour local fauna.

Some of the plants for sale will have been grown by chaptervolunteers from seeds, cuttings, or divisions-- from garden plantsor other sources from our chapter area. Great efforts are made tolearn the provenance of the plants at our sale, as we understandthe importance of maintaining a local gene pool.

Growing locally native plants is an important way to:Attract pollinators, including native bees, butterflies, moths,and birds-for your pleasure and their benefitProvide for endangered species (such as by growing host andnectar plants for the Green Hairstreak butterfly)Enhance corridors for native wildlifeUse less water (and less energy pumping that water)Save money on utility billsReduce the use of fertilizers and pesticidesHave a beautiful, colorful, lively gardenInspire your neighbors to do the same!

Sponsored by the Miraloma Park Improvement Club

To assist with your plant selections, you will find:

A plant list of our 2016 offerings on our websiteprior to the saleArticles and links on �Gardening with Natives��alwayson our websiteto their general plant community of originSigns indicating the plant type, habit, size, soil preferences,and wildlife interest for each speciesPhotos of the flower and/or form of each plantVolunteers with native gardening expertise offering advice

In addiiton to plants we also offer:Books used and new, large selection of note cards, and botanicalposters for purchaseBeautiful T-Shirts, totes, and aprons for purchase

Common SandasterCorethrogyne filaginifoliaby Michael Wood

It really should still be here. It used to be here.But no one has seen it in a long time.

Common sandaster is another one of thoseplants that transports me to my roots,surveying the sandy coastal slopes at the edgesof San Diego�s maritime chaparral, coastalscrub and Torrey Pine woodlands. Back then,the species was divided into 12 varieties, andthe one I was looking for, Del Mar sandaster(C. f. var. linifolia) was considered a rare andthreatened San Diego endemic. This varietyis still included on the CNPS inventory of rareand endangered plants and is still included onthe State�s list of special vascular plants, despitethat the fact that all of the varieties have beenconsolidated into a single, polymorphic specieswith no infraspecific taxa. Be that as it may,common sandaster is a real gem and always atreat when I come across it, which is not veryoften in the Bay Area.

Common sandaster is a member of thesunflower family (Asteraceae), a familycomprised of some 1500 genera and 23,000species found in nearly every corner of theworld. North America alone is host to 418genera and 2,413 species, where it makes upthe most taxonomically diverse family in theflora of North America north of Mexico. TheNorth American members of the family arefound from the high Arctic tundra and polardeserts to the scrub of the Sonoran Desert,and from alpine habitats to salt marshes.

If you�re an old timer, or a retro-botanistinterested in plant taxonomy as it was practicedbefore the modern era of DNA sequencing,you might associate members of the sunflowerfamily with the artificial tribes to which theywere once assigned. If so, then telling you thatcommon sandaster is in the AstereaeTribemight be meaningful. Other locally occurringmembers of this tribe include coyotebrush(Baccharispilularis), mock heather(Ericameriaericoides), the gumplants (Grindeliaspp.), San Francisco lessingia(Lessingiagermanorum), goldenaster(Heterothecasessiliflora ssp. bolanderi), seasidedaisy (Erigeronglaucus), the goldenrods(Solidagospp.), and others.Worldwide, thereare some 170 genera and 2800 species in thistribe, with 77 genera and 719 speciesoccurring in North America.

The genus Corethrogyne is monotypic, meaningthat it is comprised of a single species. Thismight surprise you as there are three specieswith a total of 14 varieties listed in Munzeand Keck (1973), 12 of which belong to C.filaginifolia. All of those varieties, with all ofthe variations in morphologies and habitataffinities they represent, have been condensedinto a single species now. That might make

many of you cheer for joy, as we�re accustomedto taxonomy becoming only more complex.I have mixed feelings.

Common sandaster is a perennial herb orsubshrub, spreading from a central base andgrowing up to 3 feet) tall. Stems are typicallydensely white-tomentose, giving the plantsan almost ghost-like appearance when foundon sandy sites. Leaves are alternate, 1-7 incheslong, linear to spoon-shaped, entire to toothed,and hairy. Leaves may be sessile or with awinged petiole, and with or without sunkenor stalked glands. The inflorescences ofcommon sandaster consist of one or moreradiate heads in a cyme-like cluster. Theattractive flower heads produce 10-43 rayflowers varying in color from white, to pink

to purple, with a center of yellow disk flowers.The involucres are hemispheric to bell-shaped,top-shaped, or cylindric, with 30-90phyllariesin 3-9 series, often spreading or withspreading tips, reflexed in age. Floweringoccurs July through November. The flowersof common sandaster serve as nectar sourcesfor a wide variety of butterflies and it is thehost plant for the northern checkerspotbutterfly (Chlosynepalla).

As I mentioned, common sandaster was oncecomprised of 12 varieties. These wereassociated with a wide variety of habitats, soiltypes, geographic ranges and elevations. Now,all of those varieties have been subsumed intoa single wide-ranging taxon. As such, commonsandaster is associated with coastal scrub,chaparral, grassland, foothill woodland, andforest habitats from sea level to 8500 feet inelevation. It is found on coastal slopes, sandy

flats and slopes, stabilized coastal dunes, dryrocky canyon slopes, and even on serpentinebarrens. The geographic range of commonsandaster stretches from southwestern Oregonto northern Baja California, Mexico. It hasbeen reported from 34 of the State�s 58counties, from coastal counties north of theBay Area, and across the breadth of Californiafrom the Bay Area southward.

In the San Francisco Bay Area, commonsandaster is, well, not so common. It is notconsidered a locally significant plant in theEast Bay (Lake, 2010), occurring in theBerkeley Hills, Mt. Diablo and the HamiltonRange (Ertter and Naumovich, 2013). It isknown from nine areas in San Mateo and SantaClara counties (Corelli, 2011), and in SantaCruz County, where it is considered a locallysignificant species, it is known from threedisparate regions (Neubauer, 2013).

In our chapter�s area, common sandaster wasrecorded historically from shallow rocky soilson Potrero Hill, serpentine slopes aboveHunters Point, and sandy hills near LakeMerced (Howell et al., 1958). Collectionshave been made at the Presidio (1893), PotreroHill (1892), and Hunters Point (1928 and1957). It has not been collected since.Somewhat surprisingly, common sandasterhas never been reported as occurring on SanBruno Mountain.

There is an unconfirmed report of commonsandaster occurring at Fort Funston in a dataset compiled by the Golden Gate NationalRecreation Area (Wood, 2014). If true, thiswould represent the only extant occurrenceof the species at the north end of the SanFrancisco Peninsula. A concerted effort torelocate the species there is warranted. Despitethe presence of suitable habitat for commonsandaster in the Presidio, on San BrunoMountain, and numerous other locales in theCity, no populations of the species remain.

Common sandaster has been assigned theranking of A2 as a locally significant species(Wood, 2015). This is a good species to be onthe lookout for, being readily recognizable. Itis also an excellent candidate for reintroductionto suitable sites in the City. Be sure to let meknow if you find it! Happy hunting.

NATURAL RESOURCES MANAGEMENT PLAN FINAL EIRTO BE RELEASED SOON

URGENT! We Need Your Help: A Date has FINALLY been setfor a joint hearing before the combined SF Planning and Recreation& Park Commissions about the Natural Resources ManagementPlan (NRMP, formerly known as SNRAMP))

When: Thursday Sept 29, time TBA (but almost certainly startingduring the day)Where: City Hall, room TBA. More exact information will becirculated via the chapter Google Group as it becomes available.

What will happen at the Sept 29 hearing (in a nutshell): (1) Planning staff who oversaw preparation of the EnvironmentalImpact Report (EIR) and RPD staff who know the NRMP, thesubject of the EIR, will make presentations, and answer questionsposed by Commissioners. (2) After possibly hours of public comment from thoseopposed to, or supportive of, certification and/orapproval of the management plan, the PlanningCommissioners will vote on a motion to certify the Final EIR,meaning they judge the analysis of possible environmental impactsof the Management Plan to be sufficiently complete and accurate. (3) The RecPark Commissioners will vote on a motion to approvesome version of the Management Plan. This will mean, in principle,that RPD can then finally start implementing the Plan. (But seeCaveats below.)

What YOU can do: (1) Put Sept. 29 on your calendar. If at all possible, plan to beat the hearing and to speak in favor of Certification and Approval. (2) Attend meetings TBA before Sept 29 to learn more and tohelp develop suggested talking points for those making publiccomment, either in person. or by email or phone. (3) If you can�t make it on Sept 29, follow instructions (to besent out via the Chapter Google group) on how to contact theCommissions to register your support. (4) ADD YOUR EMAIL ADDRESS TO THE CHAPTERGOOGLE GROUP LIST AT THE SEPTEMBER MEMBERPROGRAM (OR EMAIL RACHEL KESEL atyerba.buena.cnps.chapter@gmail.com) SO WE CANCONTACT YOU WITH MORE INFO!

Note: The Sept 29 hearing will be very long and will attract ahuge crowd. There are many who are opposed to the ManagementPlan for various reasons; they will show up to speak against certifyingthe EIR and/or in opposition to approving the Management Plan.It is super important that there be more supporters of the Planthan opponents attending. Strategies on how to minimize timespent at the hearing will be communicated to those on the GoogleGroup email list and/or who attend the meetings described in (2)under �What you can do�.

Caveats: (1) All involved expect that certification of the EIR will beappealed. This means at some point, probably before the end ofthe year, there will be a hearing at the Board of Supervisors atwhich the appellants will try to make a case that the EIR is notaccurate, is not complete, or both. SO IT IS LIKELY THAT OURJOB WILL NOT BE DONE AS OF SEPT. 29.WHEN THE TIMECOMES, WE WILL NEED PEOPLE TO CONTACT

SUPERVISORS WITH COMMENTS URGING THEM TO DENYTHE APPEAL, and to show up at the hearing to make publiccomment. (2) If the appeal is denied it is likely there will be a lawsuit.In other words, this may be a protracted battle. The goal is tosupport RPD�s efforts to start actually implementing theManagement Plan for their Natural Resources.

THANK YOU IN ADVANCE FOR HELPING. This is a hugeenvironmental issue; CNPS chapter members have been involvedfor years. Getting the management plan finally approved andimplementation started will be a massive victory for those whosupport the concept of preserving biodiversity in SF�s city parksand understand this means the natural resources in those parksneed to be managed.

For more information, contact Linda Shaffer, Chapter LegislativeChair, (ljshaffer1@comcast.net) or Jake Sigg, Chapter ConservationChair, (jakesigg@earthlink.net).

THREAT TO THE CRYSTAL SPRINGS WATERSHEDThe issue of unrestricted recreational access to the Crystal SpringsWatershed is scheduled for the San Francisco Board of SupervisorsLand Use & Transportation Committee on Monday September 12. Our chapter is part of a coalition of environmental groups thatoppose this opening for a large number of reasons having to dowith damage to the natural resources--but also for the importantmatter of protecting our drinking water. The meeting begins at1.30 in City Hall, but at time of writing we don't know where itwill be on the agenda.

Your attendance is urgently requested, as the Open the Watershedgroup, including mountain bikers, will be there in force and theSupervisors need to understand that there is great concern abouttaking this drastic step. Background information and breakingdevelopments will be provided by emailing Jake Sigg:jakesigg@earthlink.net

SAN FRANCISCO COMMISSION ON THE ENVIRONMENTSan Francisco has earned plaudits for its Integrated Pest ManagementProgram, the first in the nation, enacted in 1996. It has beenemulated by dozens of public agencies nationwide, and receivedthe 2006 National IPM Achievement Award. San Francisco'sapproach to screening pesticides has now been adopted by the U.S.Green Building Council.

The Department of the Environment takes direction from themayor-appointed Commission on the Environment. The presentCommission has several new members who want to further tightenan already strict pesticide policy, and what it proposes goes beyondthe science. Proposed changes threaten the work of the City'sNatural Resources Division (formerly Natural Areas Program).The Division is severely understaffed, and new restrictions wouldfurther burden it, without compensating benefits.

At our request, a large group turned out for the March Commissionmeeting and talked eloquently regarding biodiversity and theimportance of preserving it. It was impressive, and we are askingfor turnout when it comes back to the Commission at its meetingon November 2 at 5 pm in City Hall. It would be helpful if youcan come. Please email jakesigg@earthlink.net for more informationand for any changes in meeting schedule.

CNPS PARTNERSHIP WITH SAN FRANCISCORECREATION AND PARK DEPARTMENTFor almost 20 years CNPS has partnered with the RecPark NaturalAreas Program every Wednesday from noon to 3 pm. This is avery rewarding activity and is the best way to get to know nativeplants and wildlife and get an intimate glimpse of ecologicalprocesses. No longer will you have to wonder about why youshould care whether plants are native or not. Participants findareas and plants they didn't even know existed squirreled away inodd corners of this endlessly-varied city. And we always have fun. If you are able to come during weekdays, emailjakesigg@earthlink.net.
