It is well known that fire suppression in forests has led to an increase in catastrophic forest fires. The same has been assumed to be true for fire suppresion in shrublands. However, a recent USGS study has found that urban sprawl -- not fire suppression -- is largely responsible for the wildfires that occur in the shrublands of southern and central-coastal California.

U.S. Geological Survey scientists of the Western Ecological Research Center will report on the effects of exotic animals on native plants in Channel Islands National Park at the 5th California Islands Symposium, in Santa Barbara, Calif., Mar. 29-Apr. 1.

Chemical contamination in San Francisco Bay has decreased since enactment of the Clean Water Act in 1970, but the bay is still suffering from "contaminant stress," according to a a U.S. Geological Survey chemist who has been analyzing the bay’s waters for 30 years.

From the Gold Rush of 1849 through the 1960’s, California produced about 3,300 tons of gold, or about one-third of all U.S. gold production, but it left a legacy of detrimental environmental effects whose damage may never be fully determined, according to Roger Ashley of the U.S. Geological Survey in Menlo Park, Calif.

The environmental effects of the California gold rush and the effects of earthquakes on the urban environment are two of the topics that will be covered by scientists from the U.S. Geological Survey at this week’s annual meeting of the American Association for the Advancement of Science (AAAS) at the Anaheim Convention Center, Anaheim, Calif., Jan. 21-26, 1999.

Sitting in the darkened cab of a pick-up truck on a California Central Valley back road, research biologist Joe Fleskes of the USGS Western Ecological Research Center strained to hear the faint "beep beep beep" from his radio-tracking receiver. Somewhere out in the foggy night, the radio signal was emanating from a small transmitter worn by one of 320 ducks and geese fitted with these monitoring d
