IDAHO — A federal judge halted a large logging project near Yellowstone National Park because he said the US Forest Service submitted plans that made it impossible to judge how it would affect critical grizzly bear habitat. The 16,500-acre project located in the Custer Gallatin National Forest would have allowed the US Forest Service to select timber and build roads for logging. But without offering specifics, the project only pledged that its plans would consider the total distance of the roads and not exceed certain parameters in acreage size, designed to protect critical bear habitat. However, Judge Donald Molloy said that the plans amounted to giving the Forest Service permission and trusting that it would be compliant later. He also said that the plans also made it difficult to judge how the logging project would impact grizzly habitat.
