The fate of reintroduced wolves in Yellowstone National Park and central Idaho is on the line today as introductory arguments are heard today in a case before the 10th US Circuit Court of Appeals. Two years ago, a federal judge in Wyoming ruled that the Interior Department’s reintroduction program violated the Endangered Species Act, and ordered that the two reintroduced populations be removed. He later stayed his order while the environmental group Defenders of Wildlife appealed the decision. The American Farm Bureau, representing the interests of area ranchers, is hoping that the appeals court upholds the earlier ruling, while the feds and greens are banking otherwise.
