H.R. 39. This bill determined the fate of the last great wilderness in North America. The Senate Energy Committee reported a bill far weaker than the House bill, and conservationists tried to strengthen it on the Senate floor. The vote is on the Jackson amendment to table (and thus kill) the Hart-Chafee amendment, which would have protected an additional 14.5 million acres as national wildlife refuges. These areas included an expanded Arctic National Wildlife Range, which is vital habitat for Alaska's largest remaining Caribou herd, and protection of the Yukon Flats marshes, one of the most important nesting areas in North America for migratory water birds. The Carter administration supported the amendment and opposed this motion to kill it. July 22, 1980. Rejected 33-64. NO was the correct vote.
