If you venture out into parks, farms and gardens with various flowering species, you are almost sure to see European honeybees flying about.  When we think of bees, those are the ones that usually come to mind.  But there are more than 1,600 native bee species in California alone, and many of those are threatened with extinction.  Krystle Hickman is a National Geographic Explorer, conservation photographer, and native bee expert who uses her photography to raise awareness about the decline of native bee species and their complex ecosystems.  Her new book, The ABCs of California Native Bees, a compendium of text about and stunning photos of native bees in their California habitats, has just been published by Berkeley's Heyday Books.  Learn how a conservation photographer goes about her work and how she finds those bees.
