A compact, user-friendly field guide to 
50 of the most prominent and ecologically significant plant 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 trees, flowering plants, fruit-bearing plants, marine plants, and fungi found across the Pacific Northwest bioregion—including Douglas Fir, Sitka Spruce, Large-leafed Lupine, Wild Mint, Salal, Salmonberry, Marine Eelgrass, Red-belted Polypore , 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, and 
beachcombers, and draws awareness to the importance of conservation and 
protection of these crucial species.
