"The Ivory-Billed Woodpecker of Rare Wildflowers" This is a photo that botanists in the 20th century never thought would exist. Mount Diablo buckwheat was believed extinct after 1930 before its spectacular rediscovery on the mountain in 2005. In 2016 came an even more startling find: millions of seedlings on a slope in Black Diamond Mines Regional Preserve. David Rains Wallace tells the story in the July-September issue of Bay Nature. | Photo by Lech Naumovich, Golden Hour Restoration Institute
