A talk by Al Keuter LOCATION:Los Altos Library Orchard Room\, 13 S.

Thi s talk will focus on understanding the recent historical identities of the surviving Santa Clara County oaks.\nBesides learning about the oaks that su rround us, Al will also talk about these and other oak mysteries:\n\n - Whe re does the blue oak group fit into the red/golden/white oak scheme? (So ch romatically confusing!!)\n\n - Are native California oaks super-closely rel ated to oaks anywhere else in the world, or are they something special?\n\n - Is it tricky to apply a specific scientific name to a California oak tre e?

Norris Center for Natural History at the University of California, Santa Cruz, he has generated 40,000+ images, and made 900 collections of fruit and leaves from more than 500 oak trees in 38 California counties.

Of the approximately 600 species of oaks worldwide, roughly 21 are nat ive to California, organized into three groups: the red oaks (sometimes cal led black oaks), the golden oaks (or intermediate oaks), and the white oaks . This talk will focus on understanding the recent historical identities of the surviving Santa Clara County oaks.

Besides learning about the oa ks that surround us, Al will also talk about these and other oak mysteries:

  • Where does the blue oak group fit into the red/golden/white oak scheme? (So chromatically confusing!!)

  • Are native Califo rnia oaks super-closely related to oaks anywhere else in the world, or are they something special?

  • Is it tricky to apply a specific sci entific name to a California oak tree? (Spoiler alert: can be!)

    • Please join Al as he shares parts of his journey examining the many mysteries of California oaks.
