Events & Workshops
Join Kyle Mason from the Big Chico Creek Ecological Reserve to hear about the history of fire in Butte County, how it's been used, and why. Kyle will follow-up with a discussion of how fire management might look in the future.
Create a seasonal and local color palette from Northern California plant-based dyes with artist, designer, and educator Sasha Duerr. Together we’ll learn to “cook with color” and make a unique and biodiverse palette of botanically-dyed samples, finished take-home textiles exploring a range of surface design techniques in the process . . . and connect to a vibrant array of California fall colors.
There are many pests and diseases that cause decline in oak trees. This workshop will explore the common pests of oaks, including a discussion of the biology of the pests and common symptoms and signs of infection. In addition to the common pests, learn about a new and potentially devastating invader in California’s oak woodlands, the Mediterranean Oak Borer!
Ephemeral geophytes at high elevations are only available for study for five to six weeks after snowmelt and therefore are rarely investigated. From 2009 to 2021, Hal Mackey and Rob Schlising collected life history data on the closely related Dicentra uniflora and Dicentra pauciflora in the Cascade Range of northeastern Butte County, California, through field surveys and plantings. Join us to learn how these 16 years of data have provided insights into recovery times and persistence after major forest fires.

Join the authors of Firescaping Your Home: A Manual for Readiness in Wildfire Country to explore paradigms that get in the way of landscaping for defensible space or supporting native biodiversity. We will focus on psychological conventions in landscaping that often complicate the adoption of firesafe strategies, including foundation plantings, fences, wind patterns, and habitat fragmentation. We will wrap up with a discussion on support for biodiversity and fire insurance challenges.
Join us for a hands-on workshop to explore the identification, diversity, natural history, habitat and plant associations of our local native bee fauna. This workshop is open to all levels of “bee” experience!
The Siskiyou Crest has one of the highest concentrations of officially designated botanical areas on National Forest lands in the country. This presentation will take you on a photographic exploration of these unique Botanical Areas and highlight many of the rare and endemic species that grow in each area.

Join John Whittlesey, author of Plant Lovers Guide to Salvias to learn about the evolution and adaptation of salvias generally, their specific California habitats, and the pollinators with whom they co-evolved.
The Friends of the Ahart Herbarium (FOAH) is celebrating its 30th year of sustaining the Ahart Herbarium at Chico State! Your dedication is helping to build an endowment to secure the Herbarium's future. Our collection of almost 130,000 specimens, continues to serve scientists, students, and plant enthusiasts worldwide. In celebration our accomplishments, we invite you to the no-cost FOAH 30th Anniversary Phytoblitz and Picnic at the Vina Plains Preserve.
Celebrate California native plants! Submit your favorite California native plant photo for a chance to win $100.00 and a Friends of the Ahart Herbarium annual membership!
Herbarium specimens form an invaluable record of plant diversity and distribution. Join the Curator of the Ahart Herbarium, Lawrence Janeway, to hear about the importance of collecting plant specimens, how anyone can do it, and get some helpful hints on how you can ensure that what you collect is useful to the herbarium and researchers in general.
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 Naomi Fraga, Director of Conservation Programs at the California Botanic Garden, to learn about rare alkali wetland plants and her research supporting conservation of four at-risk species.
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?

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.”
