Lawrence constructed a twenty-eight mile fence enclosing over twenty thousand acres of private, state and federal lands in an area of south central Wyoming known as the Red Rim.
The land in this area is owned in the familiar "checkerboard" pattern as the result of the federal land grant to the Union Pacific Railroad.
Lawrence has fee title or permission to fence from the title owner of the private sections and has grazing permits on the federal and state sections. The fence enclosed 15 sections, or approximately 9,600 acres of unreserved public domain. However, the fence was constructed entirely on private lands, except where it crosses the common corners of state and federal sections.
Lawrence grazes his cattle on the Red Rim during the spring and summer months for about 60 days. But during the winter, portions of the Red Rim provide critical range for Wyoming pronghorn antelope. The fence Lawrence constructed, however, was antelope-proof, denying antelope access to this critical winter range. The winter of 1983 was unusually severe (even for Wyoming) and the testimony to the district court indicated that antelope collected against the fence and starved in an unsuccessful attempt to reach the Red Rim.
The government brought this action under a statute adopted by Congress in 1885, the Unlawful Inclosures of Public Lands Act, 43 U.S.C. §§ 1061 to 1066 ("UIA"), seeking an order compelling removal of the fence or modification to allow free and unrestricted access by pronghorn antelope to the enclosed public lands.
The Wyoming and National Wildlife Federations were joined as intervenors and moved for a preliminary injunction to have portions of the fence removed before the winter of 1985. At the hearing on the motion for a preliminary injunction, the district court consolidated the matter into a full hearing on the merits pursuant to Fed.R.Civ.P. 65(a)(2). At the conclusion of the hearing, the court orally granted the preliminary injunction, ordering Lawrence to remove certain portions of the fence within 10 days and to remove the entire fence or modify it to conform with Bureau of Land Management ("BLM") standards within 60 days. A few days later, the district court entered a final judgment and order directing that the entire fence be removed or modified. Lawrence appeals from the district court's order.
