Climate Linked to "Silent Streams"?

Memo to anglers: If you’re wondering why they’re not biting, it may be because they’re not there. Little noticed this week was a report from the U.S. Geological Survey, detailing the staggering losses that freshwater fish species have suffered across the U.S. The report describes nearly 40% of North America’s freshwater fishes as “imperiled.” The figure represents a 92% increase over a similar survey done in 1989 by the American Fisheries Society, which participated in the new report. USGS director Mark Myers cited loss of habitat and invasive species as primary causes for the decline but noted that “climate change may further affect these fish.” The news is worse for California, as topping the Survey’s at-risk list are “salmon and trout of the Pacific Coast and western mountain regions.”

Release of the report followed by one day Terry Root’s keynote presentation at the California Climate Change Conference, in which the Stanford researcher warned of a catastrophic loss of trout habitat in California, due in part to climate change.
