Creating Inks and Watercolors from Locally Sourced Plants and Minerals

Learn about the origins of color, work with select rock and plant samples, and take a local walk to learn about different species that can create exquisite colors for calligraphy, printing and painting. Each participant will learn paint grinding techniques, and take home a sample card of local colors, along with an instructional pamphlet on how to reproduce the process.

Fire‐Injured Trees: Predicting Mortality and Assessing Hazard

***This Workshop is Full***

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.

Introduction to Willow Identification

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.

Riparian Ecology along the Middle Sacramento River

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.
