In the Fault Zone

April 01, 2006 by Horst Rademacher

On April 18, 1906, a massive earthquake centered just west of San Francisco ruptured the earth from Humboldt to San Juan Bautista. While the more dramatic traces of this 7.8 temblor may be hard to find one hundred years later, the tectonic forces that moved the earth that day are still relentlessly shaping our young […]

Deep Water Corals in Monterey Bay

Sempervirens Fund Purchase

April 01, 2006 by Aleta George

At the turn of the last century, when a forest fire broke out in the Santa Cruz Mountains, writer Josephine Clifford McCrackin helped start a campaign that led to the formation of the Sempervirens Club, which has […]

Threatened Steelhead

April 01, 2006 by Aleta George

In late December 2005, the National Marine Fisheries Service (NMFS) reaffirmed the threatened status of Central California Coast steelhead trout (Oncorhynchus mykiss), including steelhead in Bay Area streams. NMFS added that the Central Coast steelhead population—first listed as threatened under the Endangered Species Act in 1997—is “likely to become endangered within the foreseeable future.” Courtesy […]

Happy Trails

April 01, 2006 by Cindy Spring

The single-track trail along the creek looks quite inviting: just wide enough for hiking, with no fallen limbs or nasty briars sticking out, a canopy overhead. It all seems so natural. But Melvin Johnson knows better. As operations coordinator for the East Bay Conservation Corps, he oversees a dozen crews that maintain trails in the […]

On April 18, 1906, a massive earthquake centered just west of San Francisco ruptured the earth from Humboldt to San Juan Bautista. While the more dramatic traces of this 7.8 temblor may be hard to find one hundred years later, the tectonic forces that moved the earth that day are still relentlessly shaping our young and active landscape, carrying us towards another cataclysm in the near future.

On The Move

April 01, 2006 by Doris Sloan

All of the familiar landforms we see here in the Bay Area—ridges, cliffs, lakes, and even San Francisco Bay itself—are products of the same titanic encounters between tectonic plates that produce our frequent quakes. Through a geologist’s trained eye, we learn to interpret the signs these forces have left on the land around us.

Letter from the Publisher

April 01, 2006 by David Loeb

I was working at my computer at the Bay Nature office in Berkeley the other day when I was interrupted by a short, sharp jolt. I looked around at the others working in the office: “Did you just feel that?” It turns out there had been a 3.4 quake centered two miles southwest of Orinda. […]

On the Beaten Path

April 01, 2006 by Bill O’Brien

Trails are the main way we access most of the Bay Area’s diverse and abundant open space. Despite that, it’s easy to forget that trails have to be planned and built by someone. However, for the East Bay Regional Park District, which has over 1,000 miles of trails, this is a full-time job. At places like the newly-opened Brushy Peak Regional Preserve, trail planners must balance people’s desire for access with the needs of native plants and animals.

Squawk of the Auklet

April 01, 2006 by Michelle Hester

Not many people get to visit Año Nuevo Island—you need a rubber boat, a strong stomach, and a research permit. But sea lions haul out here in droves, and hundreds of seabirds—including rhinoceros auklets—come to breed on its few wind-swept acres. Today, erosion is threatening the auklets’ deep burrows, so researchers are working to restore this critical breeding site for these strange-looking seabirds.
