Fall on the Yukon Flats National Wildlife RefugeThe Yukon Flats National Wildlife Refuge encompasses most of the Yukon Flats.Aspen forest in Yukon Flats National Wildlife Refuge
The area is a major waterfowl breeding ground, and after a proposal to flood the Yukon Flats via a dam on the Yukon River was turned down, the Yukon Flats were deemed worthy of protection.
On 1 December 1978, US President Jimmy Carter designated the Yukon Flats as a National Monument on the basis of the Antiquities Act of 1906. In the course of the Alaska National Interest Lands Conservation Act of December 2, 1980, the area boundaries were changed after political criticism and the status was downgraded to that of a wildlife refuge. It is the third-largest National Wildlife Refuge in the United States, although it is less than one-half the size of either of the two largest, the Arctic National Wildlife Refuge, or the Yukon Delta National Wildlife Refuge.[1] The refuge is administered from offices in Fairbanks.
