The Mysterious World of the Bull Kelp Forest

A mesmerizing tour of our underwater forests and what they can teach us.

Offshore and out of sight to most beachgoers on the North Pacific coast is a wondrous habitat: the bull kelp forest. Each year, tiny bull kelp saplings explode into sixty-foot "redwoods," until winter storms tear them loose and fling great tangles of wrack on the shore. While they flourish, these underwater forests harbor abalone, salmon, and rockfish, and they entreat cormorants and murrelets to hunt among their thrumming canopies. Meanwhile, sea otters and sunflower sea stars gorge on spiny urchins who, if left to run rampant, will devour a kelp bed down to barren wasteland. In The Mysterious World of the Bull Kelp Forest, Josie Iselin profiles thirteen species--with stylish illustrations from Ellen Litwiller--to be our ambassadors to this undersung world. She explores how their interspecies dramas play out in eight coastal regions, from Central California to Alaska, exploring instances of interdependent, compromised, and resilient coastal ecosystems. An array of sea creatures feature in these pages, as well as shorebirds that connect land and sea. Land-dwelling humans are also deeply implicated in this saga--by turns beneficiaries, agents of harm, and stewards of these subtidal sanctuaries.
