The California Supreme Court on Monday said petitioners seeking to remove a subset of coho salmon from the state's endangered species list could present new evidence to argue the listing was wrong.
In a unanimous ruling, the court overturned a lower court decision that said efforts to remove the salmon and other species could only argue that the listing was no longer necessary.
The high court decision came in a lawsuit by Big Creek Lumber Co. and the Central Coast Forest Association, which includes forest landowners. They filed a petition to remove a subset of coho salmon from the state's endangered species list, arguing that the listing was wrong because the fish were not native to the area and were introduced and maintained there artificially using hatcheries.
The fight was over coho salmon in streams south of San Francisco. The Fish and Game Commission listed those salmon as endangered in 1995.
Environmental groups were keeping a close eye on the case to see whether the court would rule on the native species argument. It did not do that and instead sent the case back to the appeals court for that determination.
"We don't accept that they are not native fish just because they are hatchery raised," said Lisa Belenky, a senior attorney at the Center for Biological Diversity, which filed a brief in the case.
