A compact, user-friendly guide to ecologically significant animal species of the Northwest Coast. A keystone species is an organism that defines and supports an entire ecosystem, filling a vital ecological niche. Without these species, ecosystems would be radically altered or even collapse. This full-color, pocket-sized field guide by best-selling naturalist Collin Varner highlights fifty keystone birds, mammals, amphibians, insects, fish, shellfish, and mollusks found across the Pacific Northwest bioregion.
