The William Main Seminar Series in Forestry and Natural Resources was established in 1986. The program honors its namesake, a graduate of Berkeley's forestry program, and longtime friend of Cal and its forestry program. William Main was, until his death in 1981, a community leader and president of the Main Industries, Inc. in Bieber, California. In 1986 his wife, Berkeley graduate Rocky Main, and the couple's sons inaugurated the Main lecture series to provide a forum for exploring topical issues in forestry and natural resource management. The Main series has always attracted a diverse group of people. Past series have focused on the Quincy Library Group, conservation of the northern and California spotted owl, impacts of forestry practices on California's Native American communities, as well as discussion of several ballot initiatives on a broad range of natural-resource issues. The Main series provides a rare opportunity for students, both undergraduate and graduate, to ask direct questions of leaders in their field, both in a formal classroom setting and later in the day, over dinner at the Berkeley Faculty Club. This program exists because of the incredible generosity of the Main Family.
