My Colby-Sawyer Experience

“My classes stress the interconnectedness of knowledge. A recent Fulbright fellowship provided the opportunity to work with undergraduate and graduate students at Kyoto Seika University in Japan. My teaching at Colby-Sawyer College is enhanced thanks to this experience.”
Fine and Performing Arts Professor Jon Keenan

Welcome to the Desert Herbarium!
This is a herbarium consisting of flora that grows in the desert. Unlike locations where water is abundant, the desert receives an average of less than 10 inches of rain annually. Combined with intense heat, deserts can be one of the harshest places for life to exist. Desert flora has evolved over millions of years to cope with such extremes. The pictures shown on this herbarium were collected by students and instructors of the Desert Communities class.
A click on the common name will take you to the plant's individual page where you will find pictures as well as descriptive information.
