This 2013 photo provided by the California Department of Fish and Wildlife shows a department environmental scientist holding a dead juvenile Coho salmon found in Little Larabee Creek in Humboldt County, Calif. Federal biologists have identified the free-wheeling marijuana industry in the Emerald Triangle of Northern California and Southern Oregon as a key threat to salmon in danger of extinction. The final recovery plan for threatened coho salmon in the region was published Tuesday, Sept. 30, 2014 in the Federal Register. It calls for getting a better handle on how much water pot growers illegally withdraw from creeks where young fish struggle to survive, and minimizing it.
