Mason Bee Revolution: How the Hardest Working Bee Can Save the World--One Backyard at a Time.The national media regularly features dire stories on honeybee colony collapse and its danger to our food supply. But there's another, unsung bee that has the potential to save the planet—the mason bee. Mason Bee Revolution explains how docile, hard-working, solitary mason bees (and their compatriots, the leafcutter bees) are even more productive pollinators than honeybees, and keeping them can be a fun, easy, backyard hobby for gardeners, conservationists, foodies, and families everywhere. ; ; Why these bees? Bee pollination is critical for about 80 percent of US agricultural crops, increasing crop value by an estimated $15 billion annually. Since 2006, nearly a third of all honeybee hives have been lost each year, due to parasites, pesticides, habitat loss, climate change, and a newer malady called Colony Collapse Disorder.
