We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the San Francisco Bay-Delta distinct population segment (Bay Delta DPS) of longfin smelt as endangered or threatened and to designate critical habitat under the Endangered Species Act of 1973, as amended (Act). After review of the best available scientific and commercial information, we find that listing the longfin smelt rangewide is not warranted at this time, but that listing the Bay-Delta DPS of longfin smelt is warranted. Currently, however, listing the Bay-Delta DPS of longfin smelt is precluded by higher priority actions to amend the Lists of Endangered and Threatened Wildlife and Plants. Upon publication of this 12-month finding, we will add the Bay-Delta DPS of longfin smelt to o...

It's pretty serious, partly because (the decline) was not expected to be so severe," says Peter Moyle, a professor of fish biology at the University of California at Davis, and a leading authority on Delta fish. "The fact that it's among multiple species suggests it's some problem with the ecosystem, with the whole food web. No one is sure what's putting Delta fish in peril. One suspect is water project pumps, which are powerful enough to reverse normal currents in the Delta. CalFed and other water managers have been experimenting with the timing of water exports to reduce impacts on fish. Most of the exports previously occurred in spring, when the finger-sized Delta smelt were upstream in the estuary and would often get ground up in the pumps. Water managers tried moving the exp...

Beyond a critical point, the collective body of a unique kind of mammal or bird or amphibian or tree cannot be salvaged, no matter the first aid rendered. Wilson suggests the time has come to rename the "environmentalist" view the "real-world" view, and to replace the gross national product with the more comprehensive genuine progress indicator, estimating the true environmental costs of farming, fishing, grazing, mining, smelting, driving, flying, building, paving, computing, medicating, and so on.
