Introduction to Bryophytes

March 4–5, 2017
Brent Mishler, Ken Kellman
UC Berkeley and Bay Area field sites

The bryophytes are a diverse group of small stature but large ecological impact. There are some 23,000 described species worldwide, making it the largest group of land plants except for the flowering plants. The group includes three phylogenetically distinct lineages: mosses, hornworts, and liverworts. The bryophytes are a “key” group in our understanding of how the modern land plants (comprising the three bryophyte lineages plus the vascular plants) are related to each other phylogenetically and how they came to conquer the land environment. Although the bryophytes display much diversity, a major limitation in the use of bryophytes as study organisms has been the lack of basic floristic, ecological, and alpha-taxonomic knowledge of the plants in many regions, of which California and the southwestern United States are the most poorly known in North America.

The first day, participants will learn about basic bryophyte biology, some simple but necessary microtechniques in the lab, and the basic structure of bryophytes along with taxonomically useful characteristics. The second day, after a morning lab session, the class will caravan to a field site and learn to identify major bryophyte groups and discuss and observe their general ecology and evolutionary features. Participants should be prepared to hike up to four miles on Sunday, in possibly wet weather conditions.

Poaceae   —  

May 6–7, 2017
Travis Columbus
UC Berkeley

“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 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 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. If conditions are favorable, we will go to the field on Sunday afternoon; most of this class will take place in a lab classroom.

Wetland Delineation

May 11–13, 2017
Terry Huffman
Rush Ranch and Livermore field sites

Wetlands are typically recognized as soggy portions of the landscape that are covered—often intermittently—with shallow water, have soils saturated with water, or have plants that look different from those in the surrounding areas. Scientific studies have shown that wetlands are essential to maintaining the biological, chemical, and physical integrity of the aquatic ecosystem. State and federal programs have been established that regulate impacts to wetlands as part of their overall water quality protection strategy. These agencies differ in how wetlands are defined and how they are geographically delineated.

This workshop will emphasize the definition and delineation method for wetlands used by the U.S. Army Corps of Engineers (Corps) and U.S. Environmental Protection Agency (USEPA) to define their jurisdiction under Section 404 of the Clean Water Act. Wetland definitions and delineation methods used by state and other agencies in California, including the California Coastal Commission (CCC), State Water Quality Control Board and its Regional Water Quality Control Boards (RWQCB), California Department of Fish and Wildlife (CDFW), U.S. Department of Agriculture, and U.S. Fish and Wildlife Service will also be discussed in comparison to wetland definitions and delineation methods used by the Corps and USEPA. Other types of aquatic habitats in addition to wetlands and how they are identified and delineated by the Corps, USEPA, and other state and federal agencies will also be discussed. The course offers a clear and concise explanation and comparison of wetland definitions and methods used by these agencies including the latest changes in methodology and approaches for determining jurisdictional boundaries; explanation of key terminology, and practical hands-on field experience for private consultants, agency personnel, attorneys, academics, and the general public who are involved with resource protection, impact assessment, environmental restoration, and/or seeking project authorization from the CCC, RWQCB, CDFW, or Corps. The course instructor’s primary method of instruction is “learning by doing” so prepare yourself to get dirty!

We will meet at Rush Ranch Thursday morning and afternoon for classroom lectures and training exercises that will acquaint participants with the various definitions, terminology, and delineation approach methodologies. We will spend Friday and Saturday in the field gaining real-world experience with the meanings of definitions and associated terminology through hands-on experience using the various wetland delineation methodologies, with analysis of results and field delineation of wetland-upland boundaries. This will include exploring how and why the various definitions and associated methodologies produce different results in terms of wetland area delineated. Class will be held rain or shine!

Presented in cooperation with the Solano Land Trust.

Lodging: not provided
Meals: Not Provided—participants must bring sack lunch each day
Transportation: Driving personal vehicles up to 75 miles per day required

Butterflies: Biology, Behavior, and Identification

May 20–21, 2017
Peter Oboyski
UC Berkeley

Butterflies are conspicuous insects familiar to anyone who has walked outdoors on a sunny day. While some species have become rare or threatened due to habitat loss, many are ubiquitous in both urban and rural landscapes. Their caterpillars feed externally on plants, often sequestering toxins from their host plants to aid in their own defense. In this workshop, through classroom presentations, discussion, and hands-on activities we will explore the diversity of butterflies, their life cycles and host plants, behaviors, and identification, with a special focus on California and the Bay Area. We will then tour the Essig Museum of Entomlogy, including the now extinct Xerces blue butterfly, then head to the field to spot caterpillars and butterflies. We will also discuss how to promote butterflies in your own neighborhood by providing resources for both larvae and adults.

Course Fee: $250/$280

Exploring the Yolla Bolly–Middle Eel Wilderness   —  

July 13–16, 2017
Julie Kierstead Nelson, Heath Bartosh
Yolla Bolly Wilderness–Middle Eel Wilderness

The coast ranges of California are a patchwork of difficult to access, public and private lands that include: high and low elevation ecosystems; a variety of longitudinal and latitudinal gradients; a complex assemblage of bedrock and soil types; a myriad of climate regimes; and many areas where different floristic regions (and subregions) converge. All of these factors drive a high level of diversity. Due to the inaccessibility of the coast ranges they harbor many under-collected localities.

The Yolla Bolly–Middle Eel Wilderness is an area of the high North Coast Range of California that is lightly visited and poorly known botanically. We will be venturing into the northern end of the wilderness, in Tehama County on the Shasta–Trinity National Forest, to explore and document the flora. We will hike into a group camp site on the first day while our gear is packed in by mule! The first evening we will explore the area around our camp and begin compiling a plant list. The next two days will be spent on day hikes to nearby areas, potentially including Black Rock, North Yolla Bolly (disjunct location of foxtail pine, Pinus balfouriana), Cedar Basin (southernmost location of aspen in the Klamath/Coast Ranges), and Pettijohn Basin. Plant ID, assisted by the instructors, will be done throughout the day and back at camp in the evenings. Participants will have the opportunity to collect and press specimens for donation to California herbaria.

Note: this workshop is a four day/three night back-country camping trip. Participants are expected to bring the required gear listed below (and sent out on the packing list) and should be comfortable spending the full duration of the workshop in a remote campsite with no access to cell phone reception or amenities.

Lodging: Group camp set-up with full kitchen
Provisions: Simple, camping-style, communal meals will be provided; water is available but participants must be prepared to purify their own water
Required Gear: Backpacking tent, sleeping bag, bear canister, water purification system (filter, tablets or Steri-pen)
Hiking: Moderate to occasionally strenuous

Tejon Ranch in August: Late–Season Treasures of the Tehachapis

August 3–6, 2017
Neal Kramer, Nick Jensen, Maynard Moe
Tejon Conservancy and Tejon Ranch

The 270,000 acre Tejon Ranch, located in Kern and Los Angeles counties, is the largest contiguous private property in California and, until recently, was largely inaccessible to the public. It is a region of great biological diversity that lies at the confluence of five biogeographic provinces (Sierra Nevada, Great Central Valley, Coast Ranges, Transverse Ranges, and Mojave Desert) and four floristic regions. As such, this area is a haven for pristine vegetation, rare and endemic species, ancient oak trees, and intact watersheds.

In 2008, an agreement was made between the Tejon Ranch Company, the owner of the property, and five major environmental groups that up to 90% of the property (~240,000 acres) will be protected through conservation easements managed by the Tejon Ranch Conservancy.

This workshop will introduce participants to the biogeography and summer flora of the Tejon Ranch. Depending on road conditions, we will explore a variety of grassland, scrubland, woodland, forest, and desert communities. Tejon Ranch is home to many special-status plant species and we expect to see some of these, including the Tehachapi buckwheat (Eriogonum callistum), which is endemic to the ranch. If we are lucky, we may even see California condors flying overhead.).

Lodging: Participants have the option to stay in dorm-style rooms (limit 11) at the Bloom House on Tejon Ranch property for an additional $30/night or camp on the adjacent Bloom House property (with access to house kitchen and bathrooms) for no additional cost.
Meals: Not provided; shared kitchen available on site for food storage and preparation
Transportation: Personal vehicles with 4WD recommended but not required
Hiking: Moderate
Start Time: Thursday afternoon

Compositae   —  

August 12–13, 2017
Bruce Baldwin, John L. Strother
UC Berkeley

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 and a brief introduction to recognition of tribes. Then, we will concentrate on identifying the diversity of summer/fall—flowering composites that go unnoticed by spring-oriented botanists and will consider their evolutionary relationships and natural history. We hope this workshop will provide participants with botanical enthusiasm for California’s second spring, well after the last of the early-season bloom fades. This workshop does not include a field trip. Familiarity with a dissecting microscope and experience using dichotomous keys is useful but not essential.

Experience required: Some previous plant identification

Climate Change in California: Past, Present, and Future

September 23, 2017
Cynthia Looy, David Ackerly, Ivo Duijnstee
UC Berkeley

This course will begin with an overview of what drives climate change now and what has driven it in the recent past. We will then discuss the physics of the greenhouse effect and our planet’s energy budget. Moving on, we will leave the present for a Deep Time perspective on climate, ranging from the extreme cold 650 million years ago to the end-Permian hot house. Before lunch, we end closer to home with the climate oscillation of the recent ice ages (last few millions of years) and its effect on North American floras.

In the afternoon, we will examine the impacts of climate change on society and environment focusing on California, and consider actions at the local, regional and state level to address these challenges. Participants will be asked to consider likely impacts in their own communities and how to balance competing demands, for example increasing protection from sea level rise vs. heat waves, or 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.

Insect–Induced Plant Galls of California   —  

October 7, 2017
Kathy Schick, Diane Erwin, Joyce Gross
UC Berkeley

Plant galls provide a fascinating array of color and texture on many of the plants in our California landscape. Galls, growths of plant cells that are not normal plant organs, can be induced by a number of organisms. The most numerous as well as most beautiful and intriguing are those induced by insects. Two insect families are found only in plant galls: Cynipidae (gall wasps) and Cecidomyiidae (gall midges or gnats). Plant galls also host a whole ecology of other insects, including herbivorous inquilines and carnivorous parasitoids like the wasp family Ormyridae, which is found only in plant galls. Most of these organisms are too small for us to see, so that the only thing we notice is the colorful gall growth itself.

In this workshop, we will start by exploring the diversity of extant insect-induced plant galls and the community of species found within them. Our study will begin with a series of lectures covering gall induction, development, plant host specificity, and inducer life histories using Joyce Gross' excellent photographic images of galls and gall insects. We will then take a short campus field trip to learn how to find galls. Back in the classroom, we will dissect galls under microscopes to examine their intricate structures and view the occupiers. We will wrap up with discussion about the evolution of the plant host-plant gall interrelationships with examples from fossil galls.

Co-sponsored by the Essig Museum of Entomology and the University of California Museum of Paleontology.

Blue Oak Ranch Reserve, Mt. Hamilton, California

This course will get you started in GIS software and cover fundamentals in geography, mapping, GPS (global positioning systems) units and land cover, and other spatial data. Working in a modern internet-accessible lab as well as in the field, we will learn how to use GIS (or geographic information system desktop application), where to get freely available data, and how to make maps. This workshop will focus on the spatial technology necessary to answer questions about biodiversity, conservation, ecology and related fields. The goal of this workshop is to provide context on how GIS programs can be used to maximize projects for plant scientists and consultants working with field or historic data. Participants will learn how to make field maps and, depending on group familiarity with GIS, analyze data within the program. This course will use Quantum GIS, a free, open-source GIS program that is mac or PC compatible.

Lodging: Shared dormitories (included in course fee)
Provisions: None; shared kitchen available for food storage and prep
Requirements: Laptop with internet access and pre-installed Quantum GIS which is available for WIN, MAC and Linux OS. Make sure you have administrative privileges on your computer. Smartphone and GPS are optional, useful tools as well.
