Book Description
Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Book Description
"Common Bees of Western North America, a companion guide to our recently published Common Bees of Eastern North America, is the first species-level photographic field guide to the most commonly seen bees in the western United States and Canada. Identifying bees by species is challenging even for taxonomists. This book walks readers through the process of bee identification using breathtaking high-resolution color photos that highlight the unique characteristics of each species, making identification easier. Each species will be presented through multiple images highlighting key identifying marks, as well as silhouette images depicting the actual size of the species. Key identification features, size, phenology, floral preference, nesting, and related species will be described with range maps for every species. The book will close with a taxonomic key to bee genera of the western United States and Canada"--
