Speaker - Sula Vanderplank
When California Plants Go South: Mediterranean Mexico
Sula will give an overview of the distribution of our California plants in northwestern Baja California, where the California Floristic Province meets the Vizcaino Desert to the south. She will address weather, range limits, endemism, and changes in the biogeography, phenology and phylogenetic affinities of the plants in this ecotone. She will provide a brief look at ongoing projects towards improving our understanding of the flora of this region and protecting it through various conservation initiatives.
Sula is also studying the unique plants that grow on shell middens left behind by the indigenous peoples of the region. Her Master’s research suggests that the flora of these middens is distinct from the surrounding areas and habitats, and warrants further research.
Further, Sula is part of a project to assemble an inventory of all the rare and endemic plants of the California Floristic Province portion of Baja California (i.e., the northwest area of the state). Collaborators in this project include Bart O’Brien (Rancho Santa Ana Botanic Garden), Jose Delgadillo (Universidad Autónoma de Baja California), Steve Junak (Santa Barbara Botanic Garden), Tom Oberbauer (AECOM), Jon Rebman (San Diego Natural History Museum), and Hugo Riemann (Colegio de la Fronterra).
Sula Vanderplank is a Biodiversity Explorer for the Botanical Research Institute of Texas. Her research has focused on the macroecology of Baja California, with an emphasis on plant distributions along the Pacific Coast of the state of Baja California and the adjacent islands. Sula also serves as Science Advisor for the Mexican land trust Terra Peninsular, through which she is involved in several collaborative projects relating to conservation in northwestern Baja California, with particular regard to the conservation of Maritime Succulent Scrub, an endangered habitat found nowhere else in the world. Collaboration with staff from Huntington Botanical Gardens and Club La Mision recently culminated in a field guide, Quail-Friendly Plants of North-West Baja California, to more than 120 plant species in this region.

Speaker - Christina Schaefer
Developing a Programmatic Monitoring Approach for
With increasing development pressure on Otay Mesa, a landscape that was historically dominated by vernal pool complexes, vernal pool restoration to mitigate for development projects is becoming very frequent on the mesa. To document the progress of vernal pool restoration projects over time, post-restoration monitoring methods compare data collected at the restored vernal pools (treatment) to data collected in natural vernal pool systems (i.e., control or reference sites). To minimize impacts on the remaining natural vernal pool complexes on Otay Mesa from multiple post-restoration monitoring surveys, the U.S. Fish and Wildlife Service suggested that a programmatic reference site be identified for all vernal pool restoration projects on the mesa. The vernal pool complex J-26 is one of the last remaining relatively intact complexes and was chosen to function as the programmatic reference site. Ms. Schaefer developed a programmatic monitoring program compatible with the data collection needs for vernal pool restoration projects. The data are being submitted to the San Diego Monitoring and Management Program multi-taxa database to be available for all entities that need reference data for their vernal pool restoration success monitoring.
Christina Schaefer is originally from Germany where she studied landscape ecology and resources management. As a restoration ecologist, she specializes in the restoration of vernal pools. Christina restored her first vernal pool in San Diego in 1992 with Dr. Ellen Bauder, and has planned and installed many vernal pool restoration projects since then. While preparing the Vernal Pool Conservation Strategy for the North County MSCP, she also assisted Dr. Bauder with data collection for the Hydro-geomorphic Model for vernal pools. Recently, she assisted SANDAG as expert advisor on the City of San Diego’s Vernal Pool Habitat Conservation Plan.

Speaker - Mike Wilken
The Kumeyaay Indians (also ‘Iipay–Tiipay or Diegueño in the United States, or Kumiai in Mexico) have inhabited the landscapes of northern Baja California, Mexico, and southern California since long before European contact, originally making a living as mobile hunting, gathering, and fishing peoples in the region’s varied environments. The division of Kumeyaay territory in 1848 by two distinct nation states imposed on the region an international boundary as well as separate political and economic structures, cultures, and languages. Historical processes have reduced Kumeyaay territory and population, and transformed indigenous life-ways, yet a few elder Kumeyaay still speak their native language and maintain cultural knowledge of the environment.
This presentation will explore the questions of how contemporary ethnobotanical knowledge of Baja California’s Kumeyaay Indians makes new contributions to scientific research of diachronic human–plant interactions in the study area, and how this knowledge can inform Kumeyaay cultural and linguistic revitalization through its incorporation in interpretive exhibits. This information is a synthesis from interviews conducted with 16 Kumeyaay plant specialists, documenting Kumeyaay knowledge of traditional uses for 47 native plants as food, medicine, tools, construction materials, and ritual resources covering indigenous nomenclature, plant scheduling, harvesting, processing, and consumption, as well as cultural meanings associated with plants. Archaeological, historical, ethnographic, linguistic, and botanical literature to situate the Kumeyaay ethnobotanical data will be reviewed in a regional and diachronic context.
Mike Wilken is an anthropologist whose research and advocacy work with Native Baja Californians has explored traditional arts (pottery, basketry, oral narratives and song), ethnobotany, history, languages and cultural landscapes of the indigenous peoples of the northern Baja California region for over 30 years. He has worked closely with native artists and traditional authorities to foster cultural revitalization and sustainable community development.

Wildflowers of Orange County and the Santa Ana Mountains
In a bold new approach, this field guide presents wildflowers of cismontane southern California and some of the associated wildlife (guilds), making it much more than a traditional wildflower guide. It includes sections on geology, geography, flower parts, scientific names, plant communities, field safety, and places to go wildflower-watching, all accompanied by photographs and illustrations. In addition to common and not-so-common wildflower species, it presents rare plants not found in other field guides such as Munz’s onion; Braunton’s milkvetch; Encinitas baccharis; small-flowered morning-glory; heart-leaved pitcher-sage; chaparral beargrass; Allen’s daisy; Hammitt’s clay-cress; big-leaved crownbeard; and several unique button-celery, brodiaeas, mariposa lilies, spineflowers, tarplants, live-forevers, monkeyflowers, monardellas, navarretias, and phacelias. Guilds include milkweed, cactus, California sycamore, California buckwheat, California lilac, yucca, and cattail. Associated species include insects such as monarch butterfly, goldenbush borer beetle, snowberry clearwing moth, and native bees; and birds such as coastal California gnatcatcher, cactus wren, Anna’s hummingbird, and phainopepla.
The book (2013) is in paperback with durable cover; 10 x 7”; 500 pages; 2,300 color photos, 363 illustrations, 1 regional map, and 11 trail maps.
Bob Allen is an instructor, photographer, and entomologist/ botanist who specializes in pollination.

Speaker - Dr. Norrie Robbins
What is a native plant? When did it arrive? How do we know?”
Palynologists such as Dr. Norrie Robbins have a different view about native plants. Dr. Robbins studies the fossil spores and pollen grains of prehistoric plants in sedimentary rocks of different ages. These studies reveal that forests and plant species are ever-changing in response to climatic factors, diseases, tectonic changes, rising and falling sea levels, etc. Studies of more recent (historic) plant pollen and spores from cores drilled into soft sediments postulate on when “early people” may have arrived to our region, how they used and impacted native plant communities, and how these communities continued to change with the arrival of Europeans and other people. At this presentation, Dr. Robbins will examine questions exploring the relationship between native plants and “early people” such as: Did people arrive to California in boats 40,000 years ago planting seeds and plants from their homelands along the seashore which were important to their subsistence? Did the well-studied people who arrived in California 13,000 years ago plant seeds from their homelands to ensure important medicinal plants would be available to them? These questions are likely to spur lively discussions on what constitutes true “native plants” in our region.
Dr. Eleanora (Norrie) Robbins is a geologist, now adjunct faculty at San Diego State University, retired from the U.S Geological Service. As a Mesozoic Palynologist, Dr. Robbins studied the ever-changing plant communities in deep oil-exploration wells from the Atlantic Ocean. When she retired to San Diego, Dr. Robbins wanted to learn about the native vegetation and then became interested in the questions that will be discussed at this presentation.

Ecological Importance and Conservation of Native Bees in Southern California
Recent research estimates that over 85% of all terrestrial plant species are pollinated at least in part by animals. As pollination is a crucial process in the life cycle of plants, global declines in pollinator diversity have elicited considerable attention. Native bees are the most important pollinators in temperate ecosystems and are known to decline in the face of disturbances such as habitat loss and degradation. In recent decades, widespread development in Southern California has threatened the rich plant and pollinator communities in this biodiversity hotspot. However, despite growing conservation concerns for both native plants and native bees, little is currently known regarding how disturbances to bee communities affect the reproduction of native plants in non-managed ecosystems.
California harbors one of the richest bee communities on earth, with an estimated 2,000 native bee species, and potentially 600 of these in San Diego. Representing a wide range of sizes, nesting strategies, foraging patterns, and social behaviors, these native bee species now occur in habitats fragmented by urbanization and they coexist with the introduced super-generalist honey bee, which dominates many ecosystems. This presentation will focus on the diversity, natural history, and conservation of native bee species in San Diego, as well as discuss ongoing research to evaluate the state of pollination services in fragmented coastal sage scrub habitats in our area.
Keng-Lou James Hung is primarily an insect ecologist, but has developed a passion for the ecology and conservation of native plants through his recent work on plant-pollinator interactions. James studied bee ecology during his undergraduate at Dartmouth College and now continues this research as a PhD student at UC San Diego.

Defending the Rarest of the Rare: Habitat Restoration and Research in Support of Chorizanthe orcuttiana at Naval Base Point Loma (NBPL)
Chorizanthe orcuttiana (Orcutt’s spineflower) is an inconspicuous annual in the Polygonaceae, and is endemic to extreme coastal San Diego County. It was presumed extinct for many years until a small population was re-discovered in Encinitas in the early 1990s. Between 1997 and 2003, three populations were located on NBPL. The Soil Ecology and Restoration Group (SERG) at San Diego State University began habitat enhancement projects in 2000 to protect this species, which have continued to the present. These projects have mainly been concerned with the removal of non-native species, including iceplant (Carpobrotus edulis), acacia (Acacia sp.), and natal grass (Melinis repens). Removal of iceplant at the second population in 2003 resulted in over 200 Orcutt’s spineflower individuals surviving in 2005, and the site has continued to support this species since.
Other SERG activities in support of Orcutt’s spineflower have included annual monitoring, both of the plant and its habitat; installation of erosion control materials and native shrubs; and site maintenance. In recent years, SERG research efforts have focused on GIS mapping to determine other potential population sites on NBPL and Cabrillo National Monument; surveying these potential sites for Orcutt’s spineflower; and pollination biology.
Michelle Cloud-Hughes is a botanist and restoration ecologist with the SERG since 1997. She began working with Chorizanthe orcuttiana in 1998, and has been the SERG Project Manager for the Orcutt’s spineflower projects at NBPL since 2006.

City Heights Vision: An Urban Community Connected to
City Heights is primed to become a national model of community-based revitalization that is uniquely grounded in education, environment, and recreation arising from a highly urbanized, densely populated, low-income, and nature-deficient community. While this area faces significant challenges, its assets are immeasurable. City Heights is one of the most diverse neighborhoods in the nation and is host to rich cultural resources.
Two major projects will affect this vision: the “Living Lab” and the “City Heights Canyon Loop Trail.” The Living Lab will be located at the head of Manzanita Canyon and provide a focal point where the community engages in authentic science and conservation to understand how the world works and how they can make a difference. The Loop Trail will seamlessly integrate the urban and natural environments through a connected neighborhood and canyon trail system.

The Plants of Baja California: Diverse, Beautiful, & Fascinating
The Baja California peninsula is a narrow strip of land stretching for approximately 1,300 km in length and ranging from 45 km to 240 km in width. Its geographic position, latitudinal span, and topographic heterogeneity have conferred a diverse assemblage of weather regimes including a Mediterranean-type, winter rainfall climate; extreme arid, hot desert conditions; and tropical, summer rainfall patterns. In addition, the region's biogeographic history and physiognomy have resulted in a wide range of vegetation types including coastal sage scrub, chaparral, oak woodland, conifer forest, many desert scrub types, and tropical deciduous forest. The peninsula is also characterized by the presence of several islands varying in distance (<1 km to 240 km) from its coast, which are located in the Gulf of California (Sea of Cortés) and the Pacific Ocean. This piece of land and its adjacent islands support a wealth of species diversity in many different plant families. It is estimated that the flora consists of more than 4,000 plant taxa with approximately 30% of these known only from (endemic to) the Baja California region. Many of the plants from the peninsula and its islands are distinctive and stretch the imagination in respect to plant form and structure including the bizarre Boojum Tree/Cirio (Fouquieria columnaris), the giant Elephant Cactus/Cardón (Pachycereus pringlei), and elephant trees (Pachycormus discolor and Bursera spp.).
Jon P. Rebman, Ph.D., has been the Mary and Dallas Clark Endowed Chair/Curator of Botany at the San Diego Natural History Museum (SDNHM) since 1996.

It is often said that California shrublands are adapted to fire. However, this deceptively simple statement hides a wealth of important detail. As a start, there are many different strategies for surviving fire. Some plant species have tough root systems, and quickly resprout after fire. Other species have smart seeds that detect the passage of fire, and only germinate when the coast is clear. Yet it is a mistake to say that these species are adapted to fire. Really, they are not adapted to fire itself, but to patterns of fire, known as fire regimes. With the coming of modern society, urban development, and the resulting population boom, the Southern California fire regime has changed, and this change has dangerous consequences for California landscapes. One way to help protect native landscapes is through outreach. By doing outreach through play, we can simultaneously engage both hearts and minds, and be more effective agents of positive change.

Speaker - Fred RobertsThe live forevers, members of the genus Dudleya, are a popular and easily recognized group of succulent plants. They have been assigned to one of three groups depending on whether their flowers are united into a tube or open and star-like, originate from underground corms or form rosettes of either flattened or finger shaped leaves. Of the about 45 species are found in southwestern North America. About 25 percent of these are found in San Diego County. If you expand that area to include mainland Los Angeles, Orange, Riverside, and northern Baja California south to Cabo Colonet, the region includes well over half of all known species. Many live forevers are narrow endemics often found in dramatic settings along cliffs, sea bluffs, and vanishing landscapes. If you have seen them in flower, you know they are a delight to find and observe. Tonight, join Fred Roberts, the Chapter Rare Plant Botanist, as he tells us about this interesting group of plants. Learn something about which habitats we can expect to find them, their rarity status, the characters used to separate them, and the diversity of forms growing within our region.
Fred Roberts previously worked as an Assistant Herbarium Curator at UC, Irvine and a botanists for the US Fish and Wildlife Service but is now an botanical consultant, author, and artist. Fred is better known for his work on Orange County plants and oaks but he has always had a passion for the genus Dudleya.

Join us to discover and explore what led Everett Ruess to write, "During the last few weeks, I've have been having the time of my life. Much of the time I feel so exuberant that I can hardly contain myself. The colors are so glorious, the forests so magnificent, the mountains so splendid, and the streams so utterly, wildly, tumultuously, effervescently joyful that to me at least, the world is a riot of intense sensual delight." We all have stories to tell about why a favorite natural place, a particular species, or our personal alchemist inspires us. It's time to consider those stories, to rejoice in the lessons nature can offer, and embrace the wildness within.

Speaker - Dr. G. Timothy Gross
This presentation will examine what archaeologists have found in the archaeological record in the San Diego region that informs us about the use of native plants. Stone and ceramic artifacts give clues to plant use, and the remains of plants help to fill in the story. Charred seeds, charcoal, pollen and phytoliths give information on plants used by prehistoric Native Americans, as well as those used in the historic period. Although food is the most often considered aspect of ethbnobotany, other aspects of plant use such as their use as building material, firewood, and mastics will also be discussed. The San Diego area will be compared to other areas like the Southwest and Great Basin where much more detail is preserved in the archaeological record about the interaction of plants and humans.
Dr. Gross earned his bachelor's in Anthropology from San Diego State University. His masters and doctorate are from Washington State University. He has been involved in the archaeology of the Western US for over 40 years. He teaches at the University of San Diego and consults for Ecology and Environment, Inc.
January 17, 2012
The presentation will focus on two main topics. The first is SDCL’s proposal to dedicate approximately 10,000 acres of city-owned land for permanent open space and parkland. His second topic will be about aspects of their Canyon Enhancement Planning (CEP) Committee, created in 2009, as a guide for community stakeholders that facilitates a systems approach for integrating our natural open spaces with the fabric of the urban environment. These aspects include visual and physical canyon access, restoration, preservation, environment-based education and ecologically sensitive recreation. The pilot for the program is Manzanita Canyon in City Heights and the on-the-ground benefits are already materializing.
