In this workshop you will learn to identify plants in 15 common families, which account for over 5,000 taxa – more than 70% of the plant diversity in CA! Together we’ll cover plant parts/terms in the classroom and get hands-on field experience in the Santa Monica Mountains. Read on for details.

Objectives

Target Audience: This workshop will be taught at a beginner level and is open to anyone interested in learning about or improving their knowledge of plant terminology and the characteristics of common plant families, and becoming competent at plant keying using the Jepson Manual and online resources. Those just entering the world of plant identification will benefit from learning the diagnostic characteristics of the most important plant families in CA. Those with prior plant identification experience will be able to refresh their skills and increase their proficiency with more difficult groups such as the Poaceae (grasses) and Asteraceae (sunflowers). Emphasis will be placed on common groups of plants in Southern CA; however, information learned in this class will be readily applicable throughout CA and the world.

Full Description: This is a 3-day introductory workshop. We will begin by teaching basic plant morphology with a focus on the structures necessary for plant ID. Participants will learn the specialized terminology necessary to identify plants in 15 common CA plant families. These families contain more than 5000 taxa, which account for more than 70% of the plant diversity in CA. Learning the characteristics of these plant families will reduce the amount of time required to key many plants to genus and species. We will utilize live material and taxonomic keys to better understand morphology in each family. Scientific names, along with common names, will be used throughout the workshop. The class will include 2 days of classroom presentations and exercises and one full day in the field in the Santa Monica Mountains. Common native families, genera, and species will be covered, including species in conifer forest, oak woodland, montane chaparral, and meadows.

To earn a certificate of completion, participants must pass an optional quiz at the end of the workshop focusing on identifying common plant structures, sight ID of families covered, and effective use of taxonomic keys for plant ID.

Participants will learn:

  • Basic plant morphology terminology
  • How to recognize 15 families of vascular plants encompassing 70% of the plant diversity in CA
  • How to identify some common tree, shrub, and herbaceous species by sight
  • Tips for remembering the differences between similar plant families and species
  • How to use dichotomous keys for plant identification including The Jepson Manual, 2nd Edition
  • Additional resources available to help identify plants

The following plant families will be covered: Apiaceae (parsley), Asteraceae (sunflower), Brassicaceae (mustard), Caryophyllaceae (pink), Cyperaceae (sedge), Ericaceae (heather), Fabaceae (pea), Lamiaceae (mint), Onagraceae (evening primrose), Orobanchaceae (broomrape), Poaceae (grass), Plantaginaceae (plantain), Polemoniaceae (phlox), Polygonaceae (buckwheat), Rosaceae (rose).

Venue: Classroom portions of this workshop will be held at the CSU Channel Islands Boating Center, located at 3880 Bluefin Circle, Oxnard, CA 93036, in classroom 2. Field exercises will take place nearby in the Santa Monica Mountains. Additional details will be provided to registered participants about a week before the workshop.

About the Santa Monica Mountains: The Santa Monica Mountains provide habitat for an exceptional amount of biodiversity in close proximity to the Los Angeles metropolitan area. We will visit a variety of habitats during our time in the field including oak woodland, riparian forest, and chaparral. We will search out a number of rare Dudleya (liveforever) spp. and locally endemic Navarretia ojaiensis (Ojai navarretia). The Santa Monica Mountains are an excellent place for beginners to learn common families and genera, and for more advanced students of the CA flora to hone their skills.

Materials & Requirements

Please bring...

  • Hand lens, metric ruler
  • Clipboard, field notebook, pencils, scotch tape, bags for collecting plant material
  • Sturdy shoes/boots, hat, weather-appropriate field clothing (e.g. protection from rain, sun, heat/cold, insects, etc.)
  • The Jepson Manual, 2nd Edition (optional, but highly recommended)
  • Packable lunch for Wednesday, plenty of water and snacks for all 3 days

Materials Provided: CNPS will provide handouts, dissecting microscopes, technical references, and online resources. We will send some advance materials on plant structure terminology.

Physical Requirements: Participants should be physically able to walk up to a mile at a time on narrow and uneven paths, along roads, and trails, and remain outside for up a total of 8 hours. The workshop will be held rain or shine. We will likely spend most of our time between sea level and 2,000 feet in elevation. We will spend approx. 33% of the time in the field.
