À propos de ce livre

A compact, user-friendly field guide to

50 of the most prominent and ecologically significant animal species of

the west coast, from British Columbia to Northern California.

A

keystone species is an organism that defines and supports an entire

ecosystem, filling a vital ecological niche. Without these species, the

ecosystem would be radically altered or even collapse. This pocket-sized

field guide by bestselling naturalist Collin Varner highlights 50

keystone birds, mammals, amphibians, insects, fish, shellfish, and mollusks found across the Pacific Northwest bioregion—including the American

Crow, Bald Eagle, American Beaver, California Sea Lion, Sea Otter,

Orca, Coyote, Grizzly Bear, Giant Pacific Octopus, Chinook Salmon,

Pacific Tree Frog, Pacific Banana Slug, Mixed Bumblebee, and more.

Each entry features clear photography, etymology, descriptions, habitat

information, risks and warnings. This convenient and easy reference is

perfect for casual walkers, hikers, campers, beachcombers, sailors,

paddlers, and whale watchers, and draws awareness to the importance of

conservation and protection of these crucial species.
