Description
California’s trees are more than landmarks on the landscape—they are living archives.
Rooted in place, they carry stories of fire and ice, drought and abundance, human care and human harm. From ancient conifers clinging to alpine ridges to flowering trees shaping valleys and deserts, these species tell the long, intertwined story of land and people.
Rooted In California invites you into that story.
Led by botanists and storytellers Matt Ritter, Michael Kauffmann, and historian Jared Farmer, this five-part webinar series blends clear, accessible science with field experience, history, and deep-time perspective.
Together, we’ll learn how to recognize California’s native trees, understand the forces that shaped them, and consider what responsibility we carry as the next chapter in their lives.
What You Can Expect
- A guided journey through California’s native trees
- Clear, approachable science focused on identification, ecology, and adaptation
- Stories rooted in field experience, cultural history, and deep time
- Visual learning tools including photos, range maps, and practical ID tips
- Live Q&A and conversation each session
- A deeper sense of connection, stewardship, and place
Part 1 — What Is a Tree?
March 2 with Matt Ritter & Michael Kauffmann
An opening session that defines what makes a tree a tree—biologically, ecologically, and culturally—while setting the tone for curiosity, wonder, and connection.
Part 2 — Conifers in Detail: Giants, Ancients, and Endemics
March 9 with Michael Kauffmann
A deep dive into California’s extraordinary conifer diversity, exploring adaptations to fire, fog, snow, and drought, and meeting some of the oldest and rarest trees on Earth.
Part 3 — Flowering Trees in Detail
March 16 with Matt Ritter
An exploration of California’s broadleaf trees, from oaks and maples to desert specialists, with a focus on identification, form, and seasonal rhythms.
Part 4 — Elderflora: Trees, Time, and Memory
March 23 with Jared Farmer
This session slows the clock. Trees live across multiple tempos—annual rings, centuries-old trunks, millennia-old lineages. Through the concept of chronodiversity, we explore how long-lived trees connect ecology, culture, and ethics across deep time.
Part 5 — Big Trees of California
March 30 with Matt Ritter & Michael Kauffmann
A culminating session celebrating California’s biggest trees and forests, reflecting on their legacy, vulnerability, and what it means to care for giants yet to come.
