FALL PLANT SALE

Saturday, October 4—Tree of Life Nursery

33201 Ortega Highway, San Juan Capistrano

PRESIDENT’S MESSAGE

 

Your Chapter Board held an all-day planning retreat on July 26th. We accomplished a great deal, and I want to thank Sandy and Pete DeSimone for hosting us at Starr Ranch Audubon Sanctuary, and the board members who gave up their day and continue to contribute so much to the chapter: Jefferson Birrell, Joan Hampton, Nancy Heuler, Sarah Jayne, Brad Jenkins, Celia Kutcher, Rich Schilk, Dan Songster, and our Rare Plant Committee expert botanists Dave Bramlet and Fred Roberts.

Dave spotted a rare tarweed at Starr Ranch while we were hiking in the morning before our meetings. He was so excited that he practically ignored the tarantula we saw in our path! It was later identified as Holocarpha virgata. We have launched a “blog” for the chapter at occnps.wordpress.com, and if you go internet surfing there you can see the stunning close-up photo that Bob Allen took of the unusual tarweed after he visited it on August 10th and collected voucher specimens.

As a result of the retreat, we have discussed our local conservation issues in some depth, come close to a final draft of chapter by-laws for adoption by the membership later in the year, discussed new and innovative ideas for publicity and our communications with members and the public, laid the groundwork for a native plant symposium in the spring, set several goals for the upcoming 12 months, and much more.

WE NEED YOU! Please set aside Saturday, October 4, 2008 on your calendars, and plan to be at Tree of Life Nursery for our fall plant sale. We would welcome your participation in any capacity – buying plants, volunteering for a 1/2 day or a couple of hours, or attending the free workshop at 9:30 am entitled “Myths (and Solutions!) of Gardening with Native Plants”. We will have volunteer opportunities available for all levels of knowledge about native plants, including beginners (all volunteers receive a special thank-you gift from Tree of Life); please call or email me to volunteer. Our workshop will be an informative and lively panel discussion where you can bring your questions, too. A percentage of all plant purchases benefits the chapter, and this is one of our major fund-raisers of the year. Don’t miss it!

NATURE WRITINGS

Thea Gavin

Here's a "poemsis trilineate" that I took from the pages of one of my favorite local history books, "The Shadows of Old Saddleback," by Terry Stephenson (published in 1948). This kind of literary borrowing is called a "found poem," and it's a fun exercise. I’d like to encourage fellow CNPS members to submit their own findings (something from the Jepson manual?) for the next newsletter.

Encino y Aliso

 

Live oaks and sycamores

rule the lower canyons,

lording it over their minor tenants.

CHAPTER MEETINGS

Thursday, September 18Engage: Being part of your Garden

Speaker: Mike Evans

Whether featured in a large garden, a small townhouse yard, or arranged in decorative pots on the patio, California native plants invite a unique connection for the people who will get close and observe. Native plant gardens offer much more than outdoor decoration and landscape greenery. The plants may evoke memories of hiking or camping, announce a change in seasons, or simply attract hummingbirds and butterflies into our busy lives. These types of gardens are truly alive and invite our participation.

In a traditional "ornamental" garden, the viewer may be detached, the feeling artificial. But in native gardens there is something that makes us curious yet content, something that makes us want to spend time there. In a native plant garden, we can engage and become an integral part, experiencing a special link to our nearby wildlands.

Enjoy this special evening as Mike Evans takes us into the heart of what a California garden should be. Become inspired as we go beyond design issues, basic plant descriptions, and water savings into the real California garden. Mike will, in his eloquent yet down to earth manner, show us why native gardens are so very important for us now, especially for kids growing up in an increasingly urbanized and technical environment.

Mike Evans is the Co-owner of Tree of Life Nursery in San Juan Capistrano. Besides being a long time member and supporter of OC-CNPS, Mike is affiliated with numerous conservation, horticultural and botanical organizations. He is past president (2005) of the International Plant Propagators Society, and past president (2001) of the California Society for Ecological Restoration and recipient with Tree of Life nursery of the CNPS State Horticulture Award (2007). With his experience in native plant production, design, landscaping, and ecological restoration, Mike is an advocate for a California that deserves to look like the true “California.”

Tree of Life Nursery was established in 1976 and is now the largest native plant supplier in California. The 40-acre nursery produces a high quality line of California natives on the historic Rancho Mission Viejo in San Juan Capistrano. More than 500 species and varieties of native plants are grown in various container sizes. Tree of Life provides plants for landscaping and ecological restoration at the wholesale level, and to the general public through Casa ‘La Paz’ where plants and books are on display for retail sales. The nursery website, www.CaliforniaNativePlants.com provides information on the use of native plants in the garden. The Tree of Life Nursery catalog, entitled “Plants of El Camino Real,” is used as a planning tool for horticultural professionals and garden enthusiasts working with native plants.

Thursday, October 16-- Challenges of Controlling Invasive Wildland Weeds in Southern California

Speaker: Bill Neill

The damage caused to our natural ecosystems and local plant habitats by invasive plants is extensive. In fact, when considering loss of rare and endangered native flora, wildland weeds are ranked second only to outright habitat destruction! In Orange County we have several principal invaders that spread like disease through our county’s parks and wildlands.

Many invasive species form monocultures (dense stands of one plant) that push out native species and reduce food and shelter needed by native wildlife, including our endangered species. Some, like Giant Reed, clog creeks and thereby increase the risk of flooding during winter storms. Others, like Scotch Broom, Eucalyptus, and Pampas Grass, increase fuel loads with their flammable mass and thus dramatically increase the incidence of fire. In almost all cases these aggressive weeds are bad for California’s wildlands, Orange County included.

So how do we try to solve this problem? Prevention, discovery, early detection, and rapid response against invasive plants are excellent first steps.

Bill’s presentation will focus on the fight against tamarisk, castor bean, Ailanthus (Tree of Heaven), Spanish Broom and Arundo (Giant Reed). He will also touch on how “chemophobia” over herbicide use has hampered invasive weed control on local and regional scales.

Bill Neill has been a point man in the weed wars of Orange County and surrounding areas for many years. He serves as our chapter’s Invasive Exotics chair, is a charter member of Cal-IPC (California Invasive Plant council), and has been eradicating and controlling many of the worst wildland weeds for decades.

For more information on Bill and his work in the Orange County wildlands, read Joan Hampton’s article in the OC-CNPS Chapter January/February 2006 newsletter.

CONSERVATION REPORT

ENDANGERED SPECIES ACT UNDER ATTACK, AGAIN! The Secretary of the Interior has proposed potentially devastating changes to long-standing regulations implementing the Endangered Species Act (ESA). These changes would drastically weaken the interagency consultation provision of ESA—widely considered its most important and effective provision.

Under current regulations, federal agencies must consult with scientists at the Fish and Wildlife Service or the National Marine Fisheries Service to determine whether a federal project is likely to harm endangered species or habitat. Such interagency consultation ensures that federal projects are independently reviewed by federal wildlife experts, so that project modifications can be made as appropriate to avoid impacts. In the overwhelming majority of consultations, federal projects move forward with few or no significant changes.

The new regulations would:
- In effect exempt thousands of federal activities from review under ESA.
- Eliminate the checks and balances of independent review.
- Limit which effects can be considered harmful.
- Prevent consideration of a project's contribution to global warming.
- Set an inadequate 60-day deadline for federal wildlife experts to evaluate a project--in the instances when they are invited to participate--or else the project gets an automatic green light.
- Enable large-scale projects to go unreviewed as a whole by dividing them into hundreds of small projects.

Another proposed rule change would limit protection of a species only to where it is currently found. Under the current rule a species has protection in its entire historical range. However many endangered species have lost substantial portions of that range. For example: under the proposed changes, prior to being reintroduced, the California condor would only have been listed in zoos.

These changes will almost certainly result in detrimental impacts to special-status species and habitats and an increased tendency to overlook opportunities to avoid such impacts. These are the most significant changes to regulations implementing ESA in more than 20 years. But just 30 days have been allowed for public comment, not the traditional 90, and emailed comments will not be accepted. And, because these regulations are administrative rather than legislative, they won't need the approval of Congress.

ACTION NOW: Snail-mail a letter to Secretary Dirk Kempthorne, Department of the Interior, 1849 C Street, N.W., Washington DC 20240. Reiterate the above points and request that the public comment period be extended to its traditional 90 days. As of now, the public comment period ends September 15. CC your Congressman and Senators.

CNPS SUES FOREST SERVICE, AGAIN! Several years ago CNPS joined other enviro groups in litigation protesting the Forest Service’s proposed Land Management Plan for the four southern California Forests (Los Padres, Angeles, San Bernardino and Cleveland, totaling 3.5 million acres). Our litigation finally prevailed in spring 2008, whereupon the Forest Service (FS) denied our protest summarily.

CNPS and six other groups have taken up the option to sue the FS for a better plan. The new suit says that the 4 Forests Plan, adopted by the FS in 2005, ignores meaningful protections for environmental resources that are critical to ensure thriving populations of wildlife and healthy forests, and allows damaging resource extraction and recreation uses. The other plaintiffs are: the Center for Biological Diversity, Los Padres ForestWatch, Sierra Club, Defenders of Wildlife, Wilderness Society and California Wilderness Coalition. They are being represented by attorneys from the group Earthjustice.

Garden Making California! Style

Explore the opportunities and constraints of garden making California-style at Gardening Under Mediterranean Skies VI: California! Saturday, October 11, 2008. This one day symposium, co-sponsored by Pacific Horticulture magazine and The Mediterranean Garden Society in concert with their international Annual General Meeting, offers a rare opportunity to meet gardeners from other Mediterranean climates of the world. The symposium will take place in stunning Monterey, the first California state capitol and a region rich in history and breathtaking beauty. Gardens have always been an important part of the developed landscape of this region where they compete for attention with the dramatic natural landscape of mountain and coastline, forest and dune.

David Fross, founder of Native Sons Nursery in Arroyo Grande, will present a morning session entitled “An Overview of California Landscape and Flora” followed by “The History of California Gardens” presented by Russell Beatty, Professor Emeritus of Landscape Architecture and Environmental Planning at UC Berkeley and a consulting landscape architect in Santa Cruz, CA. Issues challenging California garden makers today will also be the focus of lively discussion.

Complementing these programs will be an afternoon tour of gardens in Carmel and the Carmel Valley (including gardens by Michelle Comeau and Bernard Trainor) that demonstrate a clear response to the region’s Mediterranean climate. The day’s events will conclude with an evening lecture by Bart O’Brien, from the Rancho Santa Ana Botanic Garden and editor of Fremontia, entitled “Garden Jewels from the California Flora”.

For further details or to register for this exciting event please visit the symposium website at http://regonline.com/medskiesvi or call the Pacific Horticulture office in Berkeley at (510) 849-1627

Beginner’s Corner: “If it ain’t broke, don’t fix it”?

By Joan Hampton

THE DILEMMAS: Why has Yucca whipplei (Chaparral Candle) been renamed Hesperoyucca whipplei, and why is it in the Agave family instead of the Liliaceae? What is the difference between a dicot (dicotyledon) and a eudicot? Why were the Milkweeds (Asclepiadaceae) merged into the Dogbane Family (Apocynaceae) and the Chenopodiaceae into the Amaranthaceae? Many of the Scroph species have a family resemblance to one another, but most of them have now been reassigned to other families, such as the unfamiliar Phrymaceae, the new home for the Monkey Flower. Why are they doing this to us? And by the way, who is this “they”?

Let’s explore the why and the how, and identify some resources to help navigate the new system.

A taxonomist is a person who attempts to arrange or classify organisms in some kind of logical order. The most famous early one was the Swedish naturalist Carl Linnaeus (1707-1778), who classified plants by the numbers of the various flower parts. He also originated the use of Latin binomial names. While later taxonomists constructed systems that were more sophisticated, they still largely relied on characteristics that were visible to the naked eye or through a light microscope.

THE CURRENT SYSTEM: Popular local checklists and wildflower guides in current use are typically based on the 1993 edition of The Jepson Manual: Higher Plants of California edited by James Hickman, which in turn is based largely upon the work of taxonomist Arthur John Cronquist. Evolutionary lineage factors into his system, but it also relies on structural similarities. Cronquist’s system is visually accessible, and we naturally like it that way—because we ourselves are visual, botanizing out in the hinterlands with nothing more sophisticated than a hand lens. Certainly, there are fine distinctions that require a microscope for diagnosis, but for the most part, the naked eye and hand lens will do.

According to the online edition of Jepson, the Angiosperm Phylogeny Group (APG), was developed “by bringing together researchers from major institutions world-wide.” The 29 botanical taxonomists who collaborated on the project “sought to provide a stable point of reference.…This system deals mostly with higher ranks and, as there are still severe limits to our knowledge, a firm classification is not possible in all cases.” The results were published in 1998 and an updated version, APG II, in 2003. It is not the final word however.

The online version of Jepson (http://ucjeps.berkeley.edu/interchange/I_treat_indexes.html) is gradually being revised according to the APG system, “to recognize only groups in which all members have evolved from a single, common ancestor (i.e., to recognize only monophyletic groups), insofar as is practical and to the extent that data bearing on this matter are available.”

This means that looking at evolution as a branching tree, it attempts to identify nodes where each new “child” plant split off from its ancestors, creating a new lineage. Each of those descendants must share specified characteristics with its ancestor, or the group has no validity. The monocots, for example, include familiar families such as palms, lilies, grasses and irises. They share characteristics such as parallel leaf veins and three-parted flowers with their unknown monocot ancestor.

Surprisingly however—and this is a major departure from Cronquist—the dicots are not a monophyletic group. A majority of them—called eudicots or true dicots—do comprise a monophyletic group, but well-known local species such as California Bay Laurel (Umbellularia californica) and Yerba Mansa (Anemopsis californica) are misfits, and hence considered outcasts.

Some of the most significant new discoveries have come from studies of plant cells, using electron microscopes and data obtained from tools such as chemical analyses.

Plant cells themselves have an interesting history. They evolved from primitive precursors that lived underwater or in hostile, anaerobic environments. At some point, those primitive cells ingested certain bacteria, with which they formed a symbiotic relationship. Mitochondria (singular: mitochondrion), the earlier symbionts, are structures responsible for respiration, converting molecules of fuel into energy. Plant cells can contain hundreds or thousands of them, wriggly little structures located where needed around the cell. A later addition was the chloroplast, derived from cyanobacteria (blue-green algae). This is the site of photosynthesis, converting light into sugar and chemical energy. Neither of these structures (organelles) is able to survive independently any longer, existing only as internal endosymbionts.

The largest volume of DNA in a plant cell is located in the nucleus. But chloroplasts and mitochondria also have chromosomes, inherited from each of their separate bacterial ancestors. In each of these, the chromosomes look and behave differently from one another and from nuclear DNA. These varied types of DNA offer valuable clues about plant evolution, precisely because of their disparate origins.

What contribution have fossil discoveries made to the study of plant evolution? There are several problems—and not just environments unfavorable for fossil preservation. First, preservation of soft parts—such as flowers, roots and stems—is rare. Secondly, unlike the s-l-o-w, even glacial pace of evolution (which Darwin referred to as “change over time”) plants can adapt and change rapidly, even within the span of a human lifetime.

When a plant evolves, forming a new species (speciation), the older version can either disappear, or can continue to coexist with the new. If a species undergoes a series of changes in a relatively short period of time, there may be too few relics of the intermediate form left to leave evidence. (This, of course, is grist for those who argue that the absence of intermediate forms “proves” that they never existed.)

But there are two hard, durable structures that often do survive: seeds and pollen grains. They are important in different ways. Remember that plants did not develop in a vacuum. To the contrary, they evolved in tandem with insect, bird and mammal pollinators, and with physical and biological agents of seed dispersion. Thus, fossil sites where seeds or pollen are found can enable archaeologists to reconstruct prehistoric environments.

From the Columbia Electronic Encyclopedia:

Although pollen grains are microscopic in size and are thus visible to the human eye only in quantity, they are so diversified in appearance that plants are often identifiable by their pollen alone, e.g., by pathology. The waxy outer covering...is marked by characteristic patterns of ridges, spines, and knobs.

And

Pollen's…outer sheath affords it some resistance to the rigours of the fossilisation process that destroy weaker objects; it is also produced in huge quantities. As such, there is an extensive fossil record of pollen grains, often disassociated from their parent plant. The discipline of palynology [from the Latin word for dust] is devoted to the study of pollen, which can be used…to gain information about the abundance and variety of plants alive—which can itself yield important information about paleoclimates.

In the past, when the best diagnostic tool was a light microscope, only larger seeds could be analyzed. Given that they can range from the size of a dust particle (e.g. epiphytic orchids of the tropical rain forest) to the foot-long seeds of the coco-de-mer palm tree, many could not be examined in detail. But with the discovery of the electron microscope, the tiniest fossils could now be analyzed—and what a wealth of information! In addition to size, seeds come in a wide assortment of shapes, colors, patterns and textures. Furthermore, seeds contain the embryo of the developing plant, and this is the basis for embryology, another valuable resource for tracing evolutionary descent.

There are other uncertainties in determining evolutionary pathways.

Evolution can be bi-directional, muddying the picture. A plant may evolve from free petals to fused petals for example, then revert back to free petals. Furthermore, since plants hybridize much more easily than animal species, a later, evolved form may back-cross with an earlier one. Furthermore, where fossil evidence reveals a series of evolutionary steps (say, A, B, C, D, E), it may not be possible to determine whether the sequence began with A or with E (E, D, C, B, A). Whew!

Letters to the Editor


Dear Editor:

This is in response to Chuck Wright's letter to the editor in the July/August issue of the OC CNPS newsletter...

It is very heartening to read of Chuck's enthusiasm for removing non-native weeds in our local wild places. If more people felt as Chuck did then surely our local wilderness areas would have fewer invasives!

I just wanted to respond with one word of caution, though (well, eight words)—If you don't know it, don't pull it! There are many, many native plants that grow in our wild open spaces that LOOK like non-native plants, but really are native. In my experience I've seen well-meaning volunteers remove Giant Wild Rye thinking that it was Arundo. There are native mustards and thistles that look just like the non-native versions. Sometimes only a botanist can tell them apart. Also, when removing "weeds," always make sure that you have permission and guidance from the land manager.

Back to Natives Restoration, in a cooperative agreement with the United States Forest Service in the Cleveland National Forest, leads a free nine month long hands-on training course for restoration volunteers. Participants learn how to remove invasive non-native plant species using tools rather than herbicides. They learn how to keep themselves and others safe in the field, how to manage restoration volunteers, and how to identify native and non-native plants. Individuals interested in attending the next series of classes, which begin on September 27, can download a registration form at www.backtonatives.org/usfs.htm. Volunteers from all wildland agencies, organizations and non-profits are welcome to participate, and then share their new knowledge and skills with others.

Thank you!

And speaking of Back to Natives…

This organization is involved in many habitat restoration and environmental education projects in Orange County. It needs and deserves a broad base of financial support to continue these efforts. Visit their website www.backtonatives.org to find out how you can help.
