This book could not have come at a better time. We stand at a crossroads, where honey bee losses and rental rates for pollination are on the rise, research is expanding our knowledge of native bees’ role in crop pollination, and growers are looking for pollination alternatives to improve crop security. Herein lies the heart of this book: It is a technical resource that brings together the latest advances in native and introduced bee management with a big-picture perspective on how to manage a farm for these pollinators’ greatest success.
Pollinators are essential to our environment. Seventy percent of the world’s flowering plants, including more than two-thirds of the world’s crop species, rely on pollinators to reproduce. The fruits and seeds from these crops are necessary for 30 percent of the foods and beverages we consume, and include the most nutritious and interesting parts of our diet: apples, watermelon, blueberries, carrots, broccoli, and almonds to name but a few. We also count on pollinators for the beef and dairy products that come from cattle raised on alfalfa. In 2000, growers in the United States were paid close to $20 billion for insect-pollinated crops. According to estimates, managed and wild native bee species, as well as nonnative leafcutter and mason bees, are responsible for close to a quarter of this value; honey bees are responsible for the rest
