Cacti, Agaves, and Yuccas of California and Nevada

Thursday 5 February, 7.30 pm

Speaker: Stephen Ingram

Plant identification workshop 6-7.15 pm. Beginners welcome



California and Nevada are known for their astonishing array of plant life, and few components of this diverse flora are more intriguing than the cacti, agaves, and yuccas. These spiny succulents have long been a source of fascination for explorers, naturalists, and scientists. Stephen Ingram's multimedia presentation explores some of the unique attributes of the plants and highlights what makes them such intriguing components of our plant communities. With stunning images of their colorful blossoms and unusual growth forms, this program showcases a number of species that occur in California's deserts and coastal areas. Following the presentation, Stephen will sign copies of his recently published book that includes 262 color photographs, 16 botanical watercolors, and 5 range maps. His photos have been used in numerous books, magazines, and calendars.

Wednesday, February 11 Arc Ecology will hold a public meeting on its Candlestick-Hunters Point development project alternatives at the Bayview Opera House. Barbecue at 5:30 PM and the meeting at 6 PM. Do come if you can and invite all you can.



This is a very important issue for the southeast section of the city and for the whole city. This meeting is a good way to become informed of some of the important issues of this complex proposal.



Here are a few excerpts from the letter sent to the San Francisco Board of Supervisors by 15 environmental and neighborhood organizations:



Taking no action at this time will not delay this project. Legally, no project can proceed until a Final EIR is approved. We are asking you to withhold premature endorsement on this proposal because we believe it has some serious but easily remedied flaws.



We share the view of the City and the developer that this project is vitally important to the City and to the Bayview Community. It has the potential to:

* provide for a final and complete remediation of the last Superfund site in the City, the Hunters Point Naval Shipyard,
* provide new economic stimulus to the City and to the Bayview, an underserved and underdeveloped community,
* provide new housing for City residents of all income levels,
* provide significant park and recreation space essential for health and quality of life,
* help the City reach one of the major goals of its Sustainability Plan, to maintain and increase the City’s biodiversity,
* provide a model for addressing water issues such as recycling and stormwater treatment, and meeting the city goal of reducing potable water use by 10 million gallons/day by 2018.

However, we believe that as presently designed the project will not only fail to meet many of these goals as effectively as it should, it may even lead to negative impacts for some of these goals.



Arc Ecology has explored some alternate concepts for the project that we believe can greatly enhance the proposed plan. We are not suggesting that Arc’s concepts should necessarily be substituted for the Lennar proposal, although further study may suggest they be incorporated into the project. They do, however, illustrate ways the Lennar proposal fails to adequately address the issues cited above and demonstrates that viable alternatives exist that would better achieve the Proposition G goals of this development project.

We have another opportunity to help Burrowing Owls at Cesar Chavez Park - Saturday Feb 7



As most of you may know, temporary fencing was put up around the owls currently living at Cesar Chavez Park to allow more space between them and park users. While we are anticipating these owls to leave in a few weeks time, we want to take this opportunity for some public outreach. Thanks to Della Dash and the East Bay Conservation Committee, we now have informational brochures about the owls that we would like to pass out to park users.



Interested?

Join the East Bay Conservation Committee Board Chair, Phil Price at Cesar Chavez Park at the southeast entrance (at the entrance sign as Marina Boulevard forces you to turn left onto Spinnaker Way) at 10am this Saturday, February 7th. Heavy rain cancels. If you plan to attend, please email Phil at pnprice@creekcats.com, or call his cell phone at 510-909-8863. It is highly encouraged to email.

Mark your calendars to be part of the work party to put Hairstreak plants into our secondly-acquired D.P.W. lot along the corridor: the Aerial Staircase (directly across the first lot at 14th/Pacheco). Sunday, February 8th. 11:30. Stay as long as you can...or just for awhile. We will actually work at both sites, and the goal is to get as many plants as we have left into the ground this remaining planting season. We really had a fantastic time last time. It gets the neighbors out and asking "What is going on?" and that is the most rewarding outreach...when we talk about the butterfly.

9. Moth jams bat sonar

...a tiger moth called Bertholdia trigona "goes berserk," making a lot of noise above the range of human hearing when a hunting bat approaches. Bats rely on their natural sonar to locate flying moths in the dark, but in the lab, the bats rarely managed to nab one of these loud moths. When researchers disabled the moth's noisemaking organs, though, bats caught the moths in midair with ease and ate them..."the work is the first example of any prey item that jams biological sonar; when threatened these moths emit a steady, broadband sound. Insect-hunting bats and their moth prey have become a classic in the study of evolutionary arms races. This is warfare," (says the researcher).

13. From Brent Plater, January 15:
"There is a development idea for more golf, among other things, south of Mori Point. I think the support for Sharp Park Golf Course from the Pacifica City Council is tied to the development proposals for the quarry: the Council's preferred plan for raising tax revenues for the city's depleted coffers is to develop the quarry and lure seniors, travelers, home-buyers, etc. with a golf 'asset' near by.

Pacificans: contact your public officials and tell them there is already too much golf in Pacifica, and we need to Restore Sharp Park!"

(I will get mail from outraged Pacificans, telling me that there is a shortage of golf in Pacifica.)

14. LTE, San Francisco Chronicle



Oppenheimer was not given his due at UC Berkeley

Editor: Thank you for the review of David Grubin's new documentary on Robert Oppenheimer. I watched it and agree that it is excellent. However, it did not answer the question that has troubled me for many years since coming to UC Berkeley as an undergraduate in 1967.



Why has the presence of one of the greatest physicists of the 20th century been virtually erased at Cal? Ernest Lawrence's name is everywhere, but Oppie's is absent except for an annual lecture series.



I attempted to answer this question in my dissertation/book Imperial San Francisco: Urban Power, Earthly Ruin. The conclusion I came to is a combination of Red Scare, anti-Semitism, public relations and the political economy of the Bomb.



Oppenheimer never got along with the boys in the Bohemian Club to which so many of the UC regents belonged and into which Lawrence was readily inducted. Lawrence was Nordic, all American and put tycoons at their ease; Oppie was not and did not. Oppie's politics were liberal; Lawrence's moved in the opposite direction as he increasingly consorted with the wealthy and powerful.



The regents have also long had a PR problem explaining why the University of California develops and promotes the most terrible weapons of mass destruction. Oppenheimer was known by everyone as the Father of the ABomb, Lawrence not so (though he should be remembered as co-father because his engineering expertise was necessary to refine U-235.) Thus, in the virtual shrine to Lawrence at the Heart of the Lawrence Hall of Science, there is only one photo of Oppenheimer and one mention of the Bomb.



Finally, the Bomb meant big money for those involved in masking it. The BNrookings Institution in 1998 estimated that the nuclear arms race has cost the nation $5.5 trillion, and some of that awresome sum went to the firms of regents for whom the nuclear arms race was a golden key to unlock the federal treasury. Lawrence himself went onto the boards of corporations heavily involved in the production of nuclear weaponry. Oppenheimer, of course, did not and was destroyed along with his brother, Frank, whom I knew when he was director of the Exploratorium.



I thought you would be interested in some of the local backstory to the Oppenheimer saga.

No convincing some folks

There aren't any. If you don't want to believe something, facts, no matter how compelling, won't convert you. Just look, for two examples, at those who don't accept that smoking is bad for you and those who reject Darwin in favour of divine creation.

Blame the economic crash on groupthink

Shooting the bankers won't do it. This crisis was born out of a capitulation to the tyranny of orthodoxy



..."We have involved ourselves in a colossal muddle, having blundered in the control of a delicate machine, the working of which we do not understand." The words are from 1930, not 2009, but John Maynard Keynes's comment is as true today. He attributed the failure to a lack of understanding. Until very recently we thought we had put that right: plenty of clever economists; many of the sharpest minds going into finance; every economic indicator meticulously tracked; information spilling out of every analyst. But we forgot that there is a massive gap between information and understanding. The latter requires judgment, and that depends on moral attributes such as courage and wisdom.



...(A professor) produced some fascinating analysis last year of testosterone and cortisol among City traders and showed how their abnormally high hormones resulted in increasingly risky, and ultimately stupid, behaviour. The average age of those trading billions of dollars was 26. It's basic stuff: young males take risks. But with the advent of yuppies in the late 1980s anyone over 45 on a trading floor was regarded as a loser; we handed over a pivotal role in our "delicate" economy to those only too happy to take huge risks with it...It was like putting kids at the controls of Ferraris: how can we be surprised at the monumental pile-up?



The voracious appetite to apportion blame is now gathering pace. Look at the history of the 1930s and such anger is to be expected, but we need to be very wary of indulging it...Dead bodies are the oldest form of sacrifice; far harder is to acknowledge that it was a collective systemic failure. Yes, some individuals were greedy, but many were simply behaving in ways that the system encouraged, and which the rest of us failed to stop.



Vengeance is a satisfying emotion, but it has a disturbing history of landing on bystanders. Rather, we need a collective reckoning and large slices of humble pie all round. As Hamlet says: "Use every man after his desert and who shall 'scape whipping?"

Intermediate Bryology: February 21–22, 2009

We will work towards genus recognition of all California mosses and liverworts, and use more advanced keys than those used in the beginner's class. Emphasis will be on the bryoflora of the central coast, but participants are encouraged to bring their own collections to work on. Course fee ($235/$260)



Grimmia: February 28–March 1, 2009

The genus Grimmia is the most diverse and abundant group of moss to inhabit the higher and dryer parts of western North America. However, Grimmia species have the reputation of being notoriously difficult to recognize. This workshop will introduce a series of tables that can be used to identify species. Course fee ($235/$260)

18. Feedback



Siobhan Ruck:

As someone who's spent hundreds - no, thousands - of hours watching hawks and ravens flying in the Marin Headlands (often together), I must take issue with the characterization of the raven as imitating a hawk's flight. Hawks are great, but I have never seen them pull off the elegant rolls and playful flourishes of ravens. Perhaps they could do so, but it doesn't seem to enter their minds. No, the raven is in a class by itself as a superb aerialist, and would only imitate a hawk for the pure sport of messing with our minds.



Dominik Mosur:

Hi Jake, I thought you might be interested in the fact that the WRENTIT looks to be staging a comeback of sorts in San Francisco.



When I first started birding the City in 2001 WRENTITS were known to remain only on Bayview Hill and occasionally one would be reported

from the coastal bluffs over Baker Beach in the Presidio.



In 2007 Wrentits were recorded for the first time at the East Wash (behind Legion of Honor) and were apparently breeding again on the

bluffs in the Presidio for at least a couple of years. Last year (2008) there were several reports of Wrentits from Glen Canyon, and Josiah Clark observed one carrying food at Lobos Creek a site they had previously been absent from (that by the way also underwent major restoration work!)



Saturday 1/31, while on a lunchbreak from the Randall I drove up to Twin Peaks reservoir to get away from the off-leash dogs that plague our Natural Area at Corona Heights. I was floored to find a pair of Wrentits quietly foraging in the scrub on the south side of the reservoir.



According to a number of sources Wrentits don't disperse very far from the site where they are hatched (I've seen figures from 500 yards to a

mile with availability and type of habitat present no doubt playing a part in this).



I think it's really exciting that a bird species which is obligate to native vegetation zones like coastal scrub and chaparral (which continue to be destroyed in CA at a rapid pace) appears to be actually expanding its range here in the city, especialy considering that at one time it was thought that its extirpation was inevitable.

Thanks for the report, Dominik. I wonder if its reappearance could be connected to the restoration work going on by agencies and by volunteers?



Alan Hopkins:

Jake, People who are intrested in Crows, Ravens, and Jays and our urban wildlife will want to read "Crow Planet: Finding Our Place in the Zoopolis" by Lyanda Lynn Haupt. Actually, it’s a good read for anyone interested in the urban/wildlife issue. It should be out in July.

Ravens not only cause problems for the Tortoise but also for our Western Snowy Plovers, Marbled Murrelets as well as other birds such as Olive-sided Flycatcher that are all but gone from the City.

I don’t have the totals from this year’s (2008-9) San Francisco Christmas Bird Count but here are some numbers to show how Crows, Ravens and Jays have increased in the area:

Steller’s Jay 1983= 8, 2008= 44

Scrub Jay 1983= 78, 2008= 202

American Crow 1983= 9, 2008= 295

Common Raven 1983= 14, 2008= 564

Thanks, Alan, and especially for the data. I worked as a gardener in Golden Gate Park from 1959 on, and these birds, with the exception of the scrub jay, were not there before the 1970s. I remember how startled I was to see my first raven, then later a crow. That must have been in the 1970s or early '80s. They have been steadily increasing since, and they are now overwhelmingly present. I can't look out my window without seeing several. And I didn't see a Steller's jay until the last 10-15 years. The first time I saw one (in my backyard oak tree) I was so excited I had to telephone someone to exclaim about it.



Preying on desert tortoise is also new; ravens never used to inhabit the desert. I've heard reports of their extending their ranges into areas where they'd never been before. All these, as you know, are just symptoms of the profound changes wrought by man.



Doug Allshouse:

Jake, Ah, the yin and yang of the raven, so perfectly touched upon by you. Observing ravens in flight is a delight to behold--their pure joy of being airborne. Their most common partners in their fun of flight are any species of buteo hawks, especially red-tailed and red-shouldered hawks around here. The raven is so superior in flight to those buteos that it's no wonder they love to harass them, just for the fun of it. I've seen red-tails get so frustrated when screaming at them doesn't work that they will barrel-roll over on their backs (in flight) and extend their talons to try and intimidate the black wonders. NOT HAPPENING!! As for their propensity of raiding nests, you can say the same for all the corvids with the jays leading the pack by sheer numbers alone.



Ravens got so good at pulling up the plastic trash bags lining the cans with their beaks in the picnic area at San Bruno Mountain that the county installed bear-proof receptacles. I remarked to the rangers that if the ravens ever figure out how to gain access to the trash, the human race can take a step down on the evolutionary ladder. Good stuff, Doug



Not many will be interested in an academic, quantifiable, take on ravens, but if you are:

Re: Item number 4 in your news letter, “life on man”- the classic book on this is The Life that Lives on Man. I forget the name of the author; I was going to Google it, but avoided doing so after reading further down in the newsletter. The book is fascinating, though it made me itchy reading it.



On Feb 1, 2009, at 12:10 PM, Young, Karl wrote:

Re. "...They see a propensity to religion as a natural human characteristic, like a propensity to language.

I'll raise you one; why not a study of the human propensity towards complete explanations. Though I'm a big fan of science and not of sacred cows I do see a bit of irony in the pride that certain people take in the ability of science to debunk, while failing to reflect on possible evolutionary causes of the need for rational explanation. "Prodding, measuring, and explaining" seem to be very powerful methods but I'm ignorant of any real "explanation" of the relationship between nature and human "understanding" of it (or maybe re. another item in this edition of Nature News, microbial understanding of it !).

Yah, Karl, I think I agree with you. As you and I know, there are a lot of 3rd-rate (and possibly 4th-rate) scientists, and your statements certainly apply to some of the work done in the name of science.

19. Evolution



Balls and brains

The quality of a man’s sperm depends on how intelligent he is, and vice versa



There are few better ways of upsetting a certain sort of politically correct person than to suggest that intelligence (or, rather, the variation in intelligence between individuals) is under genetic control. That, however, is one implication of a paper about to be published in Intelligence by Rosalind Arden of King’s College, London, and her colleagues. Another is that brainy people are intrinsically healthier than those less intellectually endowed. And the third, a consequence of the second, is that intelligence is sexy. The most surprising thing of all, though, is that these results have emerged from an unrelated study of the quality of men’s sperm.



…Alternatively (or in addition) it may be that intelligence is one manifestation of an underlying, genetically based healthiness. That is a view held by many evolutionary biologists, and was propounded in its modern form by Geoffrey Miller of the University of New Mexico, who is one of Ms Arden’s co-authors (and, as it happens, her husband). These biologists believe intelligence, as manifested in things like artistic and musical ability, is such a reliable indicator of underlying genetic fitness that it has been chosen by members of the opposite sex over the millennia. In the ensuing arms race to show off and get a mate it has been exaggerated in the way that a peacock’s tail is. This process of sexual selection, Dr Miller and his followers believe, is the reason people have become so brainy.



…Brainy men, it seems, do have better sperm. By implication, therefore, they have fitter bodies over all, at least in the Darwinian sense of fitness, namely the ability to survive, to attract mates and to produce offspring…To him that hath, in other words, shall be given. Unfortunately for the politically correct, Dr Miller’s hypothesis looks stronger by the day.

Sir: Journalists struggling to find a fitting epitaph for the Bush presidency could do worse than quote HL Mencken: "As democracy is perfected, the office of president represents, more and more closely, the inner soul of the people. On some great and glorious day the plain folks of the land will reach their heart's desire at last and the White House will be adorned by a downright moron."

John Brennan, Surrey Hills, Victoria, Australia



Sir: In Lost Eden you say that "they discovered a rich ecology". In what form? Two stone tablets? Ecology is the science that explains the interaction between organisms and environment. What the team really discovered was probably a rich and varied ecosystem.

Dag Tangen, Oslo, Norway



(I almost never use the word ecology, precisely because it is used improperly. It is a fuzzy term, and people who use it don't have a clear idea of what they mean. The dictionary defines it as the study of organisms and their relation to each other and to their surroundings. I have found that substituting 'ecosystem(s)' almost always expresses the thought. The term's misuse is so widely used and entrenched that it's unlikely it can ever be set straight. Other terms suffering a similar fate:



coup de grace: Most people pronounce it as though it's spelled 'gras'. So instead of meaning "stroke of mercy" (ie, putting something out of its misery), it would mean "stroke of fat". Correct pronunciation of "grace" is "grahss".



forte: 'Forte' is a French word, meaning strength or strong points, therefore it is pronounced fort. Yet few people know this, and pronounce it fort-ay, which is the Italian pronunciation of a word spelled the same but with a different meaning: loud. Pronounce it correctly and people look at you funny.



pristine: immaculate, perfect, in mint condition, as new, unspoiled, spotless, flawless, clean, fresh, new, virgin, pure, unused, according to the dictionary. There is no place on Earth to which you can apply that term, not even Antarctica. Yet it is used casually to apply to very degraded areas, such as scraps of original landscape in San Francisco having a modest percent cover of native plants but heavily infested with invasive plants. I even occasionally encountered it in scientific reports, and most scientists are very scrupulous in choosing and ordering words.



(More examples to come. Can you contribute some?)
