Who We Are

The Botanical Club of Wisconsin, the state's only organization dedicated to the study of our native flora, was founded in 1968 by John Thomson as an affiliate of the Wisconsin Academy of Sciences, Arts and Letters. The BCW serves the interests of amateur and professional botanists toward the common goal of learning more about our state's plant biodiversity.

BCW Winter Events


Botanical Foray Plant ID/Processing Workshop!

Saturday December 4th at the Wisconsin State Herbarium from 9:00 am to 1:00 pm.

This past summer, the Botanical Club of Wisconsin and the Wisconsin State Herbarium held their third Wisconsin Botanical Foray. During the Foray, we collected over 900 plant specimens, and now we could use your help! The specimens must be sorted and then their field identifications must be verified. In addition, some specimens that have been verified already need to be mounted. Come and give us a hand! All levels of botanical knowledge are welcome! There will be tasks that anyone can help with, and we will provide training. It will be a great opportunity to look at plants in the middle of winter and increase your plant ID skills!


The event will take place on Saturday December 4th at the Wisconsin State Herbarium from 9:00 am to 1:00 pm. Join us for an hour or for the entire time. Covid-19 protocols will be followed. Masks must be worn at all times while in the herbarium.


Please RSVP as we will limit the number of participants to 20.


Contact Mary Ann Feist (mfeist@wisc.edu; 608 890-1427) with any questions or to RSVP.
