When the sea otters disappear, why does their kelp forest habitat
disappear, too?
On the Pacific Coast of North America, sea otters play, dive, and hunt
for sea urchins, crabs, abalone, and fish in the lush kelp forests
beneath the waves. But there was a time when people hunted the otters
almost to extinction. Without sea otters to eat them, an army of hungry
sea urchins grew and destroyed entire kelp forests. Fish and other
animals that depended on the kelp were lost, too. But when people
protected the sea otters with new laws, their numbers began to recover,
and so did the kelp forests. Susannah Buhrman-Deever offers a
beautifully written account of a trophic cascade, which happens when the
removal of a single element affects an entire habitat. Asides that dig
deeper are woven throughout Matthew Trueman's dynamic illustrations,
starring a raft of charismatic sea otters. Back matter includes more
information about sea otters and kelp forests, including their
importance and current status, the effects of the international fur
trade on indigenous peoples, and a list of books and websites for
readers who wish to continue to explore.
