The U.S. Department of Agriculture unveiled a plan to manage the national forest system that would provide more flexibility in responding to modern stresses like climate change while also heading off lawsuits. But some environmental groups say (1) the plan's short on minimum standards to protect animals and watershed areas from harm, and (2) it requires buffer areas around streams and rivers critical to drinking water, but it doesn't specify the size of those areas or what activities could be precluded.
