California lichens

February 25 – 26, 2023
Jesse Miller and Klara Scharnagl
UC Berkeley and Marin Municipal Water District Field Site

Lichens are all around us and they have fascinating stories to tell. This two-day workshop will focus on developing skills for identifying common Bay Area macrolichens (foliose and fruticose lichens) to genus. Students will learn to recognize and distinguish between pollution-tolerant lichen communities that we often see in cities and the more pristine communities that occur in places with high air quality. After taking this course you will be sure to observe lichens, big or small, almost everywhere you go!

Saturday morning will begin with an introductory classroom session where we will cover basic lichen anatomy and terminology and discuss the roles lichens play in ecosystems, such as supporting wildlife. Saturday afternoon will be spent exploring the UC Berkeley campus and the natural areas just uphill from campus. We will collect some material to bring back to the lab in the second part of Saturday afternoon in order to practice keying and identification.

On Sunday, the class will meet on the UC Berkeley campus and then caravan to Mount Tamalpais, meeting at the Rock Spring Trailhead parking lot, for a half-day field trip so that students can observe lichens in their natural habitats. Total hiking time will be approximately 2 hours, including about 2 miles of walking. The class will then return to UC Berkeley for the afternoon for one more classroom session.

Transportation: Personal vehicle required for field trip (carpooling possible).
Hiking: Easy but possibly in cold, wet, and windy conditions. Some uneven terrain.
Start/End: Saturday, 9:00 a.m. – Sunday, 5:00 p.m.

Flora of Clear Creek Management Area, San Benito County   —  

April 13 – 16, 2023
Ryan O′Dell and Amelia Ryan
Base camp will be located in Jade Mill Campground

This workshop will explore three primary areas in the Clear Creek Management Area, San Benito County, a rugged, remote area of California. Come prepared for stunning landscapes, harsh environments, unique plants, a few long drives, and the challenges of a remote camping workshop (with no water at base camp). We intend to visit the following areas (final itinerary will depend on weather and road conditions):

  1. The New Idria serpentine mass, centered around San Benito Mountain, is 30,000 acres and one of the largest serpentine areas in South Coast Ranges. Extensive natural moonscape barrens are a distinctive feature of the New Idria serpentine. The dominant vegetation types are serpentine chaparral and conifer forest. Vernal pool basins are also present. Note that this area contains Naturally Occurring Asbestos (NOA) and individual permits to enter will be required.
  2. San Benito Mountain peak is the highest in the Diablo Range at 5,267 ft and has expansive views to the north and west. The diverse geology and high topography (sky island) of San Benito Mountain supports several unusual and disjunct populations of species.
  3. Joaquin Rocks are pinnacles of sandstone on a high ridge east of San Benito Mountain and offer views of the San Joaquin Valley to the east. Like San Benito Mountain, the sky island of Joaquin Rocks also supports several unusual and disjunct populations of species.

This is a field-based workshop and our base camp will be some distance from the nearest services (King City - 34 miles; Coalinga - 37 miles). There will be no services available during the weekend and cell service is limited or non-existent. Field conditions will range from warm days to cool nights. Rain is possible, but not likely.

Accommodations: Camping at Jade Mill Campground. Possible overflow in Oak Flat Campground. These campgrounds have picnic tables, shade structures, and vault pit toilets. There is no water available at the campgrounds and each participant will need to provide their own water for the entire workshop.
Meals: Not provided. Participants must provide their own meals and drinks for the duration of the workshop.
Transportation: Personal vehicle (or a spot in the caravan) is required for the workshop. A sedan can make it to the campgrounds, but travel beyond there should be in a truck or SUV with good ground clearance. Please note that travel on the BLM roads is at your own risk.
Hiking: Moderate. Most of the points of interest (field stops) will be short hikes. Some areas will have stretches of steep slopes to ascend or descend.
Start/End: Thursday, 5:00 p.m. – Sunday, 12:00 p.m.

Course fee: $515/$545

April 20 – 23, 2023
Linda Beidleman
Hastings Natural History Reservation and Monterey Bay field sites

Are you ready to jump into botanical detective work? With a working knowledge of common plant families and comfort in using taxonomic keys, identification can be an enjoyable challenge. This workshop introduces students to the flora of the Monterey area and the techniques used to identify plants of California. Emphasis will be on learning to recognize characteristics of the area’s plant families. We will practice keying plants in the field using the third edition of the book Plants of the San Francisco Bay Region: Mendocino to Monterey (Linda H. Beidleman and Eugene N. Kozloff, 2014). A general familiarity with morphological terms is helpful but not necessary; these will be reviewed during the introductory session. The majority of the workshop will be held outdoors.

Participants may drive up to 25 miles per day to the field sites and walk up to three miles each day (easy hiking). Please note that this is an introductory workshop, geared towards beginning botanists. Participants must purchase their own copy of the book.

Accommodations: Shared rooms with bunk beds located in different houses on the property. Tent camping sites will also be available.
Meals: Catered meals from dinner on Thursday through lunch on Sunday are included.
Transportation: Personal vehicle required for field trip (carpooling possible).

Flora of San Luis Obispo County   —  

April 20 – 23, 2023
Dave Keil
Based in San Luis Obispo with travel to local field sites

San Luis Obispo County is one of California's most diverse counties. Average annual rainfall varies from more than 50 inches in the coastal mountains to 6 inches or less on the Carrizo Plain. Habitats include coastal dunes and salt marshes, chaparral, coastal scrub, woodlands, forests, grasslands, and deserts. The County's flora comprises over 2000 species and includes numerous endemics. In early spring, wildflower displays often sprinkle the fields and woodlands with splashes of color. This field course will include an introductory overview of the County's features and vegetation followed by an all-day Friday trip from San Luis Obispo to the Carrizo Plain with various stops to investigate the plant life. On Saturday we will visit various coastal communities. Sunday morning will include a trip to the closed-cone forests of Cuesta Grade. Field lectures will include recent history, major plant communities, environmental factors that determine community distribution, recognition of common taxa, and other aspects of the County's diversity. Opportunities will be available to practice keying and try out the new San Luis Obispo County flora.

Accommodations: Participants are encouraged to stay in San Luis Obispo, CA or nearby areas.
Meals: Not provided.
Transportation: Personal vehicle required for field trips. Some roads are rocky and 2WD passenger cars are not advisable for all portions of the trip.
Hiking: Moderate.
Start/End: Thursday, 5:00 p.m. – Sunday, 12:00 p.m.

California Compositae   —  

May 6 – 7, 2023
Bruce G. Baldwin
UC Berkeley, Valley Life Sciences Building

Beginning with an overview of morphological characteristics of composites (family-wide), including a review of terms used in descriptions and keys, we will provide a synopsis of diversity within Compositae (also known as Asteraceae) and a brief introduction to recognition of tribes. Then, we will concentrate on identifying a wide diversity of spring–flowering composites, thereby gaining familiarity with the different group keys in the Jepson eFlora treatment and diving deeper into characteristics of the family. We hope this workshop will provide participants with botanical enthusiasm for California’s most species-rich family of vascular plants, which have an undeserved reputation for being especially difficult to understand. This workshop does not include a field trip. Familiarity with a dissecting microscope and experience using dichotomous keys is useful but not essential.

Start/End: Saturday, 8:30 a.m. – Sunday, 5:00 p.m.

Course fee: $315/$345

Plant Diversity Documentation   —  

May 12 – 14, 2023
Susan Fawcett
The Donald and Sylvia McLaughlin Natural Reserve, Lower Lake, CA

In the face of climate change, accelerating extinction, and conservation challenges, it has never been more important to document biodiversity. In this workshop participants will make museum-quality herbarium voucher specimens, contribute data to public biodiversity databases including iNaturalist and GBIF and hone plant identification skills leveraging both traditional resources and new technology. We’ll spend two nights in the heart of the inner North Coast Ranges, at the Donald and Sylvia McLaughlin Natural Reserve, which protects ~7,000 acres of diverse and rare habitats, including serpentine soils, and is nestled amidst thousands of acres of public land. Serpentine deposits cover one third of the reserve, creating habitat islands that support rare and endemic plants adapted to these harsh soils, and numerous associated endemic insects.

This workshop will be especially valuable to those working on biological inventories, those hoping to document floristic diversity for research, conservation, and fun, or those hoping to practice the art and science of plant identification, collecting, and photography in a unique setting.

To fully participate in this workshop, please bring a laptop computer. We’ll be using Microsoft Word, Microsoft Excel, and the iNaturalist smartphone app and website (if you don’t have a smartphone, a digital camera will work). Please also download iNaturalist the app before arriving at the field station. And, lastly, please bring a plant press, pen, and clippers if you have them.

Accommodations: Bunkrooms (sleeping 3 to 5 people per room) and shared bathrooms. A campsite with four cabin-tents (2 beds per tent) will also be available (approximately 0.5 miles from the field station). There will also be space to set up your own tent if you prefer. The campground has picnic tables and composting toilets. There is no drinking water at the campground. Non-potable water for washing is available.
Meals: Provided by a caterer.
Transportation: Personal vehicle required for field trips (carpooling possible).

Sky Island Flora of the White Mountains   —  

July 13 – 16, 2023
Jim Morefield, Dylan Neubauer, and Marty Purdy
White Mountain Research Center, Bishop and Crooked Creek

The White Mountains are located at the southwest corner of the Great Basin floristic region, and their geologic and habitat diversity, high relief (spanning 3,950-14,246 feet elevation), and proximity to the Sierra Nevada and Mojave Desert all contribute to an unusually rich and well-documented flora of over 1,100 taxa. They are also known for the oldest living trees, the highest point in Nevada, and the third highest peak in California. By mid-July, the subalpine and alpine floras are coming into their peak blooming periods.

Through driving tours (up to 50 miles in a day) and easy to moderate hikes (up to 4 miles), participants will have the opportunity to explore the southern half of the White Mountains, observing and identifying diverse plants and learning to recognize various geologic and ecologic settings that influence species distributions and adaptations. Thursday morning, we will start from Bishop and stop at several points up the elevation gradient to our weekend base station at Crooked Creek (10,000 feet). Friday and Saturday will be spent visiting wetland and upland sites in various geologic settings at elevations up to 13,000 feet, depending on seasonal conditions. Sunday morning will include additional field time before our final lunch stop as we leave the mountains.

COVID-19: All participants will be required to be vaccinated and fully boosted.

Accommodations: Shared dormitories with bathrooms (participants must bring their own linens). The Crooked Creek field station is at 10,000 feet and some of the field sites are a little higher. To prepare for the conditions of high elevation, participants are encouraged to spend the Wednesday before the workshop at an intermediate elevation.
Meals: Provided by field station.
Transportation: Personal vehicle required for field trip. Vehicles must have good clearance and sturdy tires (including spare!). High clearance 4x4 with extra passenger space preferred. Carpooling is encouraged.
Hiking: Easy to moderate (but at high elevation). If we go up any steep and/or rocky hillsides, it will be slow while we look at plants, and the distances will be fairly short.
Start/End: Thursday, 10:00 a.m. (in Bishop) – Sunday, 12:00 p.m.

Course fee: $650/$680

Introduction to Poaceae   —  

November 3 – 5, 2023
J. Travis Columbus
Virtual workshop

“I am the grass; I cover all.” —Carl Sandburg, “Grass”

Prominent in plant communities throughout California, the grass family, Poaceae, is the state’s second most diverse plant family (after Asteraceae). Its California members include cool-season and warm-season species, annuals and perennials, natives and exotics, and widespread dominants and rare endemics. This workshop will provide a better understanding of this ubiquitous, species-rich family. Participants will be instructed in detail on the vegetative and reproductive features of grasses. Aspects of anatomy, physiology, and ecology will also be addressed. Most of our time will be spent learning to use the identification keys in the second edition of The Jepson Manual. Special attention will be given to difficult couplets and taxa. In addition, participants will learn how to identify common genera by using diagnostic characteristics.

Note: This is a virtual workshop. Each participant will be sent a box of grass samples to work with during the workshop. Participants need access to a computer, Zoom, and a dissecting microscope.

Experience required: Some previous plant identification.
Start/End: Friday, 9:00 a.m. – Sunday, 3:00 p.m.

Mushrooms and Mycorrhizae of Mendocino   —  

December 8 – 10, 2023
Klara Scharnagl and Teresa Sholars
Albion Biological Field Station, Albion, and surrounding field sites

The north coast of California is considered to be one of the best places in North America to find both large numbers and diversity of fungi. We will be dealing primarily with the fleshy reproductive structures that most of us recognize as ″mushrooms.″ Mendocino and Fort Bragg, in the heart of mushroom territory, are ideal locations for this introduction to the systematics and ecology of California mushrooms. Through lectures, slides, and keying, we will emphasize the family and generic characteristics needed for identification. Both in the laboratory and in the field, students will learn some of the common, edible, and toxic mushrooms found in the area. Many of the mushrooms we will encounter are mycorrhizal: we will introduce students to the biology and ecology of mycorrhizal fungi, including their interactions with plants and host specificity. Two main references will be used in the class:

  1. Mushrooms of the Redwood Coast: A Comprehensive Guide to the Fungi of Coastal Northern California (2016) by Noah Siegel and Christian Schwarz. Ten Speed Press
  2. California Mushrooms (2015) by Dennis E. Desjardin, Michael G. Wood, and Frederick A. Stevens. Timber Press

The following are also very helpful: Mushrooms of the Pacific Northwest (2009), by Steve Trudell and Joe Ammirati; Mushrooms Demystified (1986) by David Arora, is a good reference but has out of date nomenclature (names and classification).

Accommodations: Shared rooms with bunk beds.
Meals: Catered (vegetarian) meals from dinner on Friday through breakfast on Sunday are included.
Transportation: Personal vehicle required for field trip (carpooling possible).
Hiking: Easy but possibly in cold, wet, and windy conditions.
Start/End: Friday, 1:00 p.m. – Sunday, 12:00 p.m.

Course fee: $535/$565

Biodiversity challenges: Floristics, taxonomy, and phylogenetics

February 11, 2023
Bruce Baldwin

Floristic studies provide a detailed inventory of the plants occurring in a particular area. Phylogenetics, the study of evolutionary relationships among organisms and taxonomy, the science of classifying organisms, come together in reference guides such as The Jepson Manual and the online Jepson eFlora. This workshop will review taxonomic changes in the Jepson eFlora, the phylogenetic bases for the revisions, and describe evidence for the changes.

Start/End: Saturday, 1:00 p.m. – 5:00 p.m.

Course fee: $25

Spatial phylogenetics

March 11, 2023
Brent Mishler and Israel Borokini

Spatial phylogenetics uses the geographical ranges of taxa, along with a corresponding phylogeny, to take an evolutionary view of biodiversity. This method shifts the focus from species alone to the whole tree of life. Areas with unique concentrations of biodiversity can be discovered, evolutionary and ecological processes that generate patterns of biodiversity can be studied, and conservation priorities on the landscape can be established. This workshop will start from the basics and build up the concepts, methods, and applications of spatial phylogenetics.

Start/End: Saturday, 1:00 p.m. – 5:00 p.m.

Course fee: $25

Fungal communities, their dynamics, and their interactions with plants

March 25, 2023
Tom Bruns and Else Vellinga

Fungi are diverse and critical components of all terrestrial ecosystems, but, unlike plants and animals, the roles and behaviors of fungi are often poorly known. This workshop will start with a brief introduction to fungi and the ways that their unique morphologies allow them to interact with their environments and play unique roles. Three types of fungal communities will be discussed in more depth: 1) ectomycorrhizal communities that form mutualistic associations with the roots of many temperate trees; 2) wood decay communities that form parasitic, commensalistic, and saprobic interactions with trees, and 3) dung communities that form saprobic interactions and are exquisitely adapted to colonize rich resources that are unpredictably deposited in time and space.

Start/End: Saturday, 1:00 p.m. – 5:00 p.m.

Course fee: $25

Deep Time: Paleobotany and plant evolution

August 26, 2023
Cindy Looy

This course will serve as an introduction to the evolution of plants and terrestrial ecosystems. We will follow the evolution of major plant groups from the invasion of land to the end of the Paleozoic (252 million years ago). One ecosystem we are going to focus on is the iconic Carboniferous peat swamps. These communities covered vast areas of what is now the US and represent the last forest biome dominated by spore plants instead of seed plants. You will get acquainted with the groups that inhabited these wetlands and the unusual conditions that facilitated their prominence, and you will learn how we reconstruct these inhabitants and their communities in incredible detail. In addition, we will interpret how major environmental changes unfolded across landscapes in the past and how plants have shaped the outside of our planet.

Start/End: Saturday, 1:00 p.m. – 5:00 p.m.

Course fee: $25

Life on the edge: Extreme environments, climate change, assisted migration, and refugia

September 9, 2023
David Ackerly

This course will provide an introduction to the science of climate change and how California’s native flora has responded to a changing climate over multiple time scales. We will examine the emergence of the Mediterranean-climate zone and the biogeographic assembly of the native flora, the evidence from the pollen record on how California vegetation responded to oscillations of the ice age, the stewardship of California’s landscape by Native Americans, and the interactions of climate, land use, and colonization since the arrival of European and American settlers.

In the second half of the workshop, we will examine the methods and models used to project the impact of future climate change in California, focusing on plant biodiversity. We will then discuss the state’s commitment to ′30x30′ (conserving 30% of California’s lands and waters by 2030), and how conservation efforts are adapting to the effects of climate change. Participants will be asked to consider likely impacts in their own communities and how to address concerns about equity of access to parks, housing, and transportation, and how to manage parks to achieve biodiversity conservation in a changing environment. Come prepared with your own questions about climate change for fruitful group discussion on the topic.

Start/End: Saturday, 1:00 p.m. – 5:00 p.m.

Course fee: $25

Seeing the Forest for the Trees: California ecology and conservation in the 21st century

September 16, 2023
Gregory Arena

With all its incredible diversity, the flora of California is the legacy of a myriad of biotic and abiotic forces. A walk in the woods and fields is not only an opportunity to experience the splendors of our natural world, but to witness the story of how life has adapted and transformed across time. Through this course we will investigate the astounding wealth of plant life and ecosystems found in the greater Bay Area by exploring a mosaic of natural history, living and non-living environmental factors that underlie ecological theory, and how this story presents itself in the physical form. We'll also consider plants and their environment in a context of anthropogenic impacts such as climate change, habitat fragmentation, invasive species, and what this means for conservation and land management.

Start/End: Saturday, 1:00 p.m. – 5:00 p.m.

Course fee: $25

Documenting Botanical Diversity: observations, specimens and field sketching

September 30, 2023
Susan Fawcett

As climate changes and biodiversity losses accelerate, species occurrence data become increasingly valuable, and are critical for informing conservation policies and priorities. In this course, we will focus on some of the uses of Big Data in biodiversity research and how citizen scientists can contribute to our collective knowledge by making excellent observations using tools like iNaturalist. In addition to taking photos, making herbarium specimens and sketching plants in the field are both great ways to gain intimate familiarity with a plant. I will cover some basic techniques using iNaturalist, Microsoft Excel, Microsoft Word, and Google Maps to: 1) create maps for finding organisms in the field; 2) automate data collection for specimens using iNaturalist, 3) use Word and Excel to make herbarium specimen labels from iNaturalist observation data, and 4) cover best practices for specimen preparation. Lastly, I provide some tips for plant ID and discuss the joys and benefits of field sketching.

Start/End: Saturday, 1:00 p.m. – 5:00 p.m.
