What comes to mind when you think of the winter holiday season? Do you think of evergreens and baking spices? Did you know that many of our native chaparral shrubs and forest trees are evergreen, and that native sages can remain fragrant for years after drying? Learn more about native plants while you create a holiday wreath, kissing ball, or garland!

Cottonwoods and willows are the most common riparian hardwood species in California and yet many of us have little idea of how to tell them apart. The goal of the workshop is to instill confidence about vegetative characteristics used in the identification keys in The Jepson Manual and familiarize participants with some of the most common willows in California.

Butterflies are among the most charismatic and easily identified pollinating insects. Join CSU, Chico entomology professor, Dr. Don Miller, to get an introduction to some of the butterfly species found in Butte County, with a special emphasis on their relationships with larval host plants. Dr. Miller will also be conducting the annual butterfly count at the Big Chico Creek Ecological Reserve on the day following the workshop and participants are welcome to join.

Grasses dominate many California landscapes, yet their identification presents a challenge to beginner and experienced botanists alike. This workshop will help you learn the morphological features and terminology used in The Jepson Manual keys so you can confidently key out those tricky species. Dried specimens of more than 20 genera and 45+ species will be provided for participants to key together as a group and as individuals.

The March 4th workshop is full, but we are offering a second Grass Identification workshop on Saturday, March 11, 2023, 9:00am – 4:30pm

Learn about the origins of color, work with select rock and plant samples, and take a local walk to learn about different species that can create exquisite colors for calligraphy, printing and painting. Each participant will learn paint grinding techniques, and take home a sample card of local colors, along with an instructional pamphlet on how to reproduce the process.

Join USDA Forest Service Ecologist Michelle Coppoletta to learn how the alteration of fire regimes is impacting important natural areas in California. Then join us for the Friends of the Chico State Herbarium annual meeting, including short presentations describing the research of the two 2019 Jokerst Award winners.

In the aftermath of fires, professionals are often asked to assess the health of trees within private and public lands. But making decisions on the health and probability of mortality in fire‐injured trees can be complicated. Join experts in the field to learn how to assess if a tree will survive fire related injuries, insect activity post‐fire, post‐fire decay and the potential hazards of decay.
International Society of Arboriculture Continuing Education Units are available for this workshop.

Is your native plant garden looking a little scruffy? This day-long workshop will cover the cultivation and maintenance of native plants in the garden. We will discuss planting, irrigation, pruning and some propagation of various trees, shrubs, herbaceous perennials and annuals. Presented by native plant experts John Whittlesey and Rob Schlising.

For many people the word “bee” is synonymous with the non‐native “honey‐ bee.” But there are many kinds of bees in nature, even within urban areas in northern California. This workshop will showcase native bees for people who like nature, and for those who are involved in land management and conservation. Presentations will range from basic and introductory to technical.

Physical river processes drive riparian ecology. This field-based workshop will examine riparian ecology along the middle Sacramento River from the perspective of flowing river water: How has flowing water determined the location of plant species across the floodplain; How has the flowing water shaped the physical structure of the vegetation. This year’s river flooding should give us a lot to explore and to discover about the riparian ecology of the middle Sacramento River.

This one‐day workshop will focus on identifying to genus the lichens of the lower Sierra Nevada/Cascade foothills. Led by Tom Carlberg, President of the California Lichen Society.

With around 800 species in California, the bryophytes (mosses, liverworts, and hornworts) are a fascinating, diverse, and ecologically important part of our native flora. The aim of this two‐day work‐ shop is to give participants the basic tools they will need to continue learning and enjoying the local bryophytes on their own.

Join botanical Illustrator Joan Keesey for this one day workshop focusing on accurate botanical drawing and graphite techniques.

Unfortunately we need to cancel the wreath workshop this year, but we hope you have a happy holiday season!

Join us for the Friends of the Chico State Herbarium’s Annual Meeting, including a special presentation by Jennifer Jewell, creator and host of the national award‐winning public radio program and podcast, Cultivating Place: Conversations on Natural History and the Human Impulse to Garden.
