The 2024 Park Fire impacted a diverse range of woodland and forest habitats, including the Beaver Creek Pinery, a unique old-growth forest shaped by frequent fires. Join US Forest Service Research Ecologist Eric Knapp to learn about the factors that allowed the Pinery to withstand historical fires and how his research may inform forest management strategies under today’s fire climate.
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 workshop is to give participants the basic tools they will need to continue learning and enjoying the local bryophytes on their own.
Fire is an integral process in many California Ecosystems which have largely been shaped through Indigenous fire stewardship. In this presentation, Dr. Don Hankins will illustrate the interconnected nature of Indigenous knowledge to shape ecocultural relationships through fire stewardship to restore ecosystems and enhance climate and social resilience.
Back by popular demand! Learn more about California native plants while you create a unique holiday wreath. Many of our native chaparral shrubs and forest trees are evergreen, and can remain fragrant for years after drying. Join us for an afternoon of creativity and good cheer!

Join Aaron Sims, Director of the Rare Plant Program for the California Native Plant Society (CNPS) to celebrate five decades of rare plant conservation and the people that make it possible.
During the first portion of this pictorial reminisce (All Things Botanical, May 16, 2024), John Dittes introduced us to Lowell, retired rancher and farmer, renowned Northern California botanist and plant collector, and namesake of the Herbarium at CSU Chico. We learned of Lowell’s early days, growing up on The Peter Ahart Ranch, and how he became the accomplished botanist we know today. We’ll continue from there, enjoying photos and stories of botanical projects, Northern California landscapes, and interesting people met along the way, from 2013 to present.
Dr. Frankie will touch on a variety of topics that illustrate his concern for pollinator conservation: The use of bee hotels (pros and cons), collecting pollinators, data basing of collections and value of museums, bee conservation and the need for citizen action. He will also discuss developing pollinator habitat gardens and native versus non-native plants in these gardens.
Forest 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 trees can be complicated. There are many factors to assess and this workshop will present information to aid in the assessment of the health of trees, particularly California native conifers and oaks. Workshop participants will be shown examples in the field of the most common native forest insects and diseases that impact local forest health.
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.
Nevada County and the cross-section of the Sierra Nevada it spans offer diverse habitats and a diverse set of plant species that inhabit them. For the first time, a true Flora of Nevada County is in the works. Join Shane Hanofee to hear about the process of making a flora, the botanical history of Nevada County, and some exciting discoveries made in the production of this work.
Join monkeyflower expert Steve Schoenig on an exploration into the beauty and diversity of monkeyflowers (genus Diplacus, Erythranthe, Mimetanthe). Steve will provide hands-on advice for the—sometimes tricky—identification of monkeyflowers and give an overview of the fantastic diversity of mokeyflowers in the state.
Please join Calflora’s Executive Director Cynthia Powell to learn about new Calflora tools for native plant professionals, gardeners, and enthusiasts! How can you better use this incredible resource to learn more about regional plants?
Join us as we reminisce on the botanical works and travels of renowned Northern California botanist and plant collector Lowell Ahart, in accompaniment of John and his life and business partner, Josephine. Seasoned botanists and those “new to botany” alike will enjoy this story and visual overview of the landscapes explored, botanical discoveries made, and interesting people met along the way.
Sorry, this workshop is full.
A group considered difficult by many people, the 90+ California manzanitas are actually easy to identify once you understand the characters and how they vary. Join authors Tom Parker and Mike Vasey to learn about this iconic group of Western North American plants.
Every year, thousands of visitors traverse North Table Mountain Ecological Reserve in Butte County, California. Most are drawn to the spectacular patterned displays of native wildflowers that peak for a few weeks during each spring. Which species are responsible for these displays? And how do the climate, geology, and hydrology of the Table Mountain mesa combine to create these striking floral designs? Learn from our speaker, Samantha (Sam) Hillaire, who is a co-author of the popular field guide, “Wildflowers of Table Mountain, a Naturalist’s Guide.”

Andrea Craig will take you on a tour of the rugged, remote, and richly biodiverse landscape of the Lassen Foothills. This conservation story will focus on Dye Creek Preserve and is about getting to know an elusive volcanic landscape, with over a century of grazing and development, and the diversity that has persevered.
Through soil seedbank studies ‘lost’ vegetation may be rediscovered, past composition highlighted, resiliency potential established and future trajectory imagined. Join Chico State Masters student Kaylie DeLuca to hear about her research on the seedbank of a restored meadow in Lassen Volcanic National Park.

Learn more about native plants while you create a holiday wreath, kissing ball, or garland!
Bumble bees are among the most charismatic, noticeable (visible and audible!), as well as critically important pollinating insects. In this talk, John Whittlesey will share photos taken over the last 8 years of bumble bees while weaving a discussion of their life history along with anecdotes of “living with bumble bees,” ending the talk with plants to plant if you too would like to invite bumble bees to live in your garden.

Join author and radio host Jennifer Jewell to explore how the power of gardens and gardeners can be viewed through a lens of seeds, and the general state of seeds in our gardened lives: how they grow, where they grow, who grows them, who sells and/or controls them, and their care up and down the seedsheds of our world.
Join Travis Columbus, Research Scientist at the California Botanic Garden, to learn about Eriogonum, one of the most diverse genera of California native plants.
