Lectures on the natural world at Quarryhill Quarryhill Botanical Garden

Saturday July 23rd -

Three award-winning speakers will present their thoughts on the future of our rich biological heritage this summer at Quarryhill Botanical Garden in Glen Ellen.

June 25 – “Saving Plants: What Can Botanical Gardens Contribute?” with Peter H. Raven, President Emeritus of the Missouri Botanical Garden.

We depend on plants for our food and many of our medicines, for cleansing the air we breathe, and for the beauty they bestow on our lives. Learning about and saving them are things we can do now, but will be ever more difficult in the future in our increasingly crowded and polluted world. Let us resolve to do the best we can while there is still time, for the benefit of ourselves and those who follow us.

July 23 – “Wilson’s Landscapes, 100 Years On” with Tony Kirkham, head of the Arboretum, Royal Botanic Gardens, Kew.

Following in the footsteps of the great English plant hunter, E. H. Wilson, Mark Flanagan and Tony Kirkham examined changes, 100 years later, in the rugged mountains of western China, home to so many of our most beloved garden plants.

Aug. 20 – “How To Avoid The Sixth Mass Extinction: Ethical Dimensions,” with Paul R. Ehrlich, Bing Professor of Population Studies, Department of Biological Sciences, Stanford University.

With Earth’s sixth great mass extinction upon us, not enough is being done and time is short for the most vulnerable of the world’s wild birds and mammals. Thousands of populations have already disappeared, other populations are dwindling daily, and soon our descendants may live in a world containing but a minuscule fraction of the birds and mammals we know today.

All talks begin at 5:30 p.m. Each lecture costs $25 for members, $35 for nonmembers. Sign up for all three and receive a 10 percent discount. To purchase tickets, go to or call 996-3166.
