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.
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.
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.

Have you ever wondered how plants are grouped into families?
Join botanists Linnea Hanson and Emily Meigs Doe to learn how to more easily identify the plants you are interested in.
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.
This workshop has been postponed. Check back soon for a new date.
Learn about the origins of color, work with select rock and plant samples, and take a local walk to learn about different species that lend themselves to exquisite color.
