Thompson voted for President Bush's Healthy Forests Initiative, which some environmentalists saw as a preference to the timber industry. He has disappointed some environmentalists with votes against limits to new commercial logging roads in Alaska's Tongass National Forest and against limits to hunting bears over bait. He was also one of only 30 Democrats to vote against an amendment to maintain roadless areas protected under the Roadless Rule. Thompson received an A+ rating for his 100% voting record from the American Wilderness Coalition in 2004.
