Palo Alto: Restoration effort benefits steelhead trout in San Francisquito Creek
The hard-luck steelhead trout of San Francisquito Creek will have one less obstacle to surmount once the storms of winter set the stage for their annual spawning runs. A construction team has removed a century-old concrete barrier from a section of the creek in El Palo Alto Park on the Palo Alto-Menlo Park border, restoring the streambed to a more natural course. The roughly 40-foot-wide structure, known as a weir, had acted at times as a dam, trapping the federally threatened fish on either side.
Study documents cigarette environmental hazards
The pollution caused by cigarette butts, along with massive deforestation from cutting down trees for wood to dry and fire cure tobacco, means smoking is seen more and more as an environmental problem. It’s a problem that’s on the rise, with an estimated 5.6 trillion cigarettes smoked annually, and more smokers in the developing world every day. “Cigarette smoking is a full service health hazard,” said Dr. Thomas Novotny, a scientist formerly at UCSF and UC Berkeley who is now a professor at San Diego State’s Graduate School of Public Health. “It’s also a full-service environmental hazard.”

Warming climate could transform Bay Area parks and open space
By the end of the century, the Bay Area’s landscape could look more like Southern California’s, raising tough questions for land managers trying to preserve the region’s protected lands. It may not be an official record, but by some accounts, more open space has been preserved in the San Francisco Bay Area than in any other major U.S. metropolitan area. More than a million acres are permanently protected from development – that’s almost one-third of the 4.5 million acres that make up the 10-county region. Now, with temperatures on the rise, land managers and scientists are beginning to ask how the Bay Area’s landscape will withstand climate change. As plants and animals are forced to shift, some of the Bay Area’s iconic parks and vistas could look dramatically different.

Don’t Lather, Don’t Rinse, Don’t Repeat
Microbeads, found in many cosmetics, are the latest addition to the marine plastics problem. Yes: You may be dirtying our waters every time you clean your face. In the summer of 2012, when they set out to measure levels of plastic pollution in the Great Lakes, a team of researchers expected to find lots of bottles, six-pack rings, and plastic bags. They expected, too, to discover plenty of microplastics: those minuscule pieces of free-floating plastic that typically result from the degradation of much larger pieces. But these researchers were unprepared for just how much micro-size trash they would discover. Some of the samples they collected from Lakes Huron, Superior, and Erie indicated the presence of as many as 450,000 bits per square kilometer—twice as many as had ever been recorded.

Ospreys taking a liking to San Francisco Bay
Although ospreys can be found worldwide, until recently there had been no record of their using the San Francisco Bay for anything other than wintering grounds. This nesting season, however, dozens of young ospreys took their first dives through the San Francisco Bay air and caught their first fish in its waters.
Ospreys go south for the winter and spend the breeding season in higher latitudes. In the past, they would pass up the San Francisco Bay to nest farther north. “If you look at the range route for opreys now it looks like ospreys come down the Pacific coast and the nesting and breeding range stops somewhere just north of San Francisco,” said Allen Fish of the Golden Gate Raptor Observatory (GGRO).
