Op-Ed: Send in the sea otters to help save California's North Coast (via latimesopinion)
Kelp forests are a crucial California marine ecosystem. From kelp’s floating canopies to its “holdfast” roots, the giant seaweed — algae, actually — supports greater biodiversity and sequesters more carbon than a redwood grove, while also protecting our coastline from the full force of Pacific storms. Kelp forests shelter fin fish, shellfish, whales, seals, octopuses and sharks — more than 1,000 animal and plant species in all.
Perhaps 300,000 sea otters once thrived along the north Pacific Rim, from Japan to Baja, until humans hunted them almost to extinction in the 19th century. They’ve rebounded since they were fully protected in the U.S. 50 years ago, and in California they’ve recolonizedWhy not farther north? Possibly because they can’t make it past a burgeoning white shark population.
Since the sea star die-off, the quarter-sized purple urchins have run amok, especially off the Sonoma and Mendocino coast, devouring kelp and replacing the complex near-shore kelp forest habitat with “urchin barrens” — a seabed carpeted with pastel pin cushions.divers — some volunteers and some paid by the state and private donors — have organized efforts
Letting otters expand their range on their own is ideal, but relocating them is possible. It could start with 10 or 12 — a sea otter SWAT team — from what’s estimated to be a California population of about 3,000. In fact, U.S. Fish and Wildlife has years of experience relocating the marine mammals with varying success, often at the behest of the fishing industry, which tends to view otters as competition.
