Invasive plants often outcompete co-occurring natives, in part due to higher photosynthetic capacity. However, it remains unclear whether these advantages arise from evolutionary shifts after introduction or reflect preadaptation in their native range. In this talk, Dr. Griffin-Nolan presents a large-scale home-away comparison of 27 invasive species (and 17 co-occurring native species) across temperate forest and field habitats on three continents.

UC Jepson Herbarium volunteer and researcher Vanessa C. Stevens has been organizing and curating the collection of California botanist, Mary E. Pulsifer Ames (1843-1902).  Specimens in the Ames collection range from 120 to 150 years old, and include vascular plants, marine algae, and cryptograms collected in California, the continental United States and around the world.  Vanessa is working to integrate this collection into the University and Jepson Herbaria, housed at UC Berkeley.

We hear about prescribed fires, forest thinning projects, and post-fire restoration projects. But how do people actually choose when and where these projects should happen? And, in a changing and much-changed world, how should we decide if they're even good or not? Wolfy will discuss the challenges, compromises, and new ways of seeing that resulted from some ecological restoration projects she took on.

Join land managers from CSU, Chico’s Big Chico Creek Ecological Reserve (BCCER) to hear about management and research projects happening on the reserve in the wake of the 2024 Park Fire. They will present ongoing projects, including longer term post-fire management planning, post-fire research and monitoring, prescribed fire reentry, and spring and oak savannah restoration projects. They will also highlight some of the new botanical discoveries on the BCCER after the fire.

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.

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.

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.

Here is some background on ecocultural stewardship in a paper that Dr. Hankins published in PNAS: Climate resilience through ecocultural stewardship

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.

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.”
