A tiny minnow that lives only in backwaters in Oregon's Willamette Valley is the first fish to be formally removed from Endangered Species Act protection because it is no longer in danger of extinction.
U.S. Fish and Wildlife Service Director Dan Ashe is scheduled to make the announcement Tuesday afternoon at a wildlife refuge outside Corvallis.

The action comes 22 years after the 3-inch-long fish was first listed as an endangered species, and five years after it was upgraded to threatened.
Paul Henson, state director for Fish and Wildlife, said the Oregon chub demonstrates that a lot of species can be brought back from the brink of extinction, if key needs are met, such as a safe place to live, even in an urban landscape.
"This doesn't mean that all of a sudden it's hands off, and we never need to do anything for them," Henson said. "But we can at least put them back in the group of species that need attention, but don't need to go into the emergency room of the (Endangered Species Act)."
The Oregon chub had practically disappeared from the Willamette Valley as the swampy backwaters and beaver ponds it depends on were drained to control flooding and create farms and cities over the past century and a half. Those that survived became easy prey for non-native predators, such as bass and bullfrogs.
Restoring the chub has focused on working with private, tribal and public landowners to protect and restore ponds and backwaters the fish needs to thrive, transplanting fish to expand its range and population, protecting them from predators, and altering dam releases to resemble natural river flows. A range of state and federal agencies, tribes, conservation groups and private landowners joined in the work.
Saving the chub faced fewer major obstacles than higher-profile species, such as salmon, which have been harmed by major economic forces, such as logging, hydroelectric dams, and urban development.
John Auer, a financial adviser, said he was initially concerned when Oregon chub were found in a beaver pond on the 900-acre farm outside Monmouth that has been in his family since the end of World War II. But it soon became clear that it was far enough from farming operations that it would not affect them. He added that he signed a safe harbor agreement with Fish and Wildlife, essentially requiring him not to poison the fish or fill in the pond.
The agency proposed the delisting a year ago after establishing 80 different populations around the Willamette Valley.
Formal notice the Oregon chub will be removal from Endangered Species protection is to appear in the Federal Register on Wednesday, Fish and Wildlife spokeswoman Elizabeth Materna said.
