24 April 2012 Species Spotlight—Sea Otters Posted by: Heidi Ridgley | Leave a comment | Share: Sea otters frolic off the coast of California. With their expressive faces and soft, furry bodies, sea otters exude charisma. But when it comes to survival, cute and cuddly doesn’t always cut it. As few as 2,800 sea otters call California’s waters home. The population descends from a single remaining colony of about 50 hidden amid the crags of Big Sur, out of sight from fur hunters who nearly wiped out the world’s entire population by the early 1900s. Today they are at risk from pollution-caused disease, oil spills and fishing gear. But even in such small numbers, these marine mustelids—related to weasels, ferrets and minks—have a profound influence on the marine ecosystem, keeping crucial kelp forests healthy by eating urchins that can overgraze. The otters’ diverse diet includes clams, crabs and mussels, which they cleverly crack open with a rock—every otter keeps one tucked away in a chest pouch. Unlike most of their blubbery brethren, sea otters have fur—the densest of any mammal at up to 1 million hairs per square inch—to keep the chilly waters at bay. Because they can’t afford a bad hair day, much time is spent grooming their “do.” If their fur becomes soiled, it’s no longer waterproof and they can freeze to death. That’s one reason oil spills are so lethal. Despite these amazing adaptations, California sea otters still need our help to keep their heads above water—so they can frolic and we can be charmed throughout this century and into the next.

Two Too Many Development Projects in the Ivanpah Valley While these projects most definitely directly impact a species that has been identified as threatened and is dependent on the habitat where they would be built, Silver State South and Stateline’s approval is most troubling for a bigger reason. You see, this isn’t just an issue for the Ivanpah Valley. Developers and agencies need to be conscious of how and where they plan energy projects all across the country. They need to look at renewable energy planning with a landscape-wide lens, understanding that building in the right places and making an effort to minimize environmental impacts from the start are essential.
