Tulare Lake – how one naturalist “fell in love” with his favorite part of the world

This speaker series is a “welcome home” for Rob Hansen, former COS Biology and Ecology professor for 35 years.  After 55 years spent studying the natural history (the ecosystems and the biota) of Central California, Rob enjoys every opportunity to share his passion about Tulare Lake and the Tulare Lake Basin when he leads field trips, teaches classes, writes articles, and makes presentations about his favorite part of the world (what Rob likes to refer to by its historical name, the “Tulare Valley”).  Before his COS career, Rob served for 9 years as biologist and wildlife preserve manager with The Nature Conservancy of California.  During that time, he was land steward for 7 major habitat types on nearly 5,000 acres of wildlife habitat at 6 wildlife preserves in the Tulare Lake Basin.

Intro will be given by Barbara Brydolf

Mark Arax has been called a “21 st Century John Steinbeck” for his books that pry open the soul of California. A writer of essays, history, biography and journalism, he is a two-time winner of the California Book Award and a recipient of Stanford University’s William Saroyan International Prize for Writing. His most recent work, “The Dreamt Land: Chasing Water and Dust Across California”, a national bestseller, has been hailed by critics as one of the most important books ever written about the West. The New York Times has named “The Dreamt Land” and one of Mark’s previous books, “The King of California: J.G. Boswell and the Making of a Secret American Empire,” to a short list of California’s best literature over the past 150 years.
