Ethnobotany

Wednesday, June 8
1-4pm

Many of the plants which we ignore on our walks in the woods actually played an important part in the everyday lives of North American indigenous people. And many people are surprised to learn what they considered as delicacies, such as grubs, baby birds, grasshoppers. Roger will also talk about how they used various trees for housing and weapons as well as the challenges of foraging for their livelihood. Among this seemingly primitive existence, indigenous people knew how to make aspirin, which they used for headaches and soothing aches and pains encountered at the "office."

About the instructor: Roger Nibler has been conducting tours at Hoyt Arboretum since 1987. Roger's particular area of interest is the many uses of plants by the Native North Americans. He also enjoys giving survival tips regarding plants to eat and avoid for those who might get lost in the woods with minimal gear. 

 Limited to 15 people. $15/member, $20/non-member.  Registration is required. Sign up below via Paypal, or contact Becky Schreiber at (503) 823-1649.
