Providing An OASIS For Threatened Salmon

Bringing sensitive wildlife back from the brink is no easy task. 

Slow and steady is the approach for the people working to help coho salmon populations recover in Oregon. 

The people of the OASIS program (Oregon Adult Salmonid Inventory and Sampling) cover a lot of distance and endure some tough conditions just to get accurate fish counts. 

Un-Damming The Salmon

EXTRA: Watch the dam demolition.

Before we fully understood anadromous fish, the kind that swim upstream to spawn, we put a lot of obstacles between them and their spawning grounds. 

Dams big and small went up on creeks and rivers, preventing fish passage. 

Now many dams are coming down, including one on Cottonwood Creek in Tehama County. 

U.S. Fish and Wildlife oversaw the project, which returns five miles of stream to spawning habitat.

It's a mouthful to say or spell "ichthyophthirius multifiliis," so most people just pronounce it "ick." 

Long or short, it's the name for a disease capable of killing fish by the thousands in the drought-stressed Klamath River

And there's evidence of a significant ich infestation in the river again this year.

Rains finally came to the region recently. 

And now they're leaving. 

Which means we're essentially back to where we were a few weeks ago: looking at a drought, likely a severe one. 

The Earth Law Center and other groups warn of stream flows too low for salmon and other fish to survive this year.

There is general agreement that the region's streams need a bit more help to be truly friendly places for fish. 

But there's plenty of disagreement over HOW to provide that help. 

Take the Trinity River in California.

For years, museum conservators and paleontologists have yearned for a way to duplicate fragile fossils without damaging them. Now scientists with the University of Oregon say they have found a way to do just that, with the help of a relatively inexpensive 3-D printer.

Pot Versus Fish In California Waters

Marijuana versus the environment: who ever would have seen that coming? 

But the first hurts the second, at least when illegal growing operations trash the landscape and nearby waterways.
