Wilderness areas
in wyoming

The 1984 Wyoming Wilderness Act permanently protected 1.1 million acres of ecologically diverse, wild landscapes. The wilderness system in Wyoming encompasses roughly 3 million acres. However, 5 million acres of spectacular wild land, spanning deserts, forests, and plains, remains unprotected.  Our top priority is to defend the wilderness characteristics of wild, roadless lands and safeguard their potential for future wilderness designation. We work to protect Wyoming’s public wildlands by inspiring the public to appreciate wilderness and roadless areas and engaging the public in public land decisions.  

Wilderness Study areas

The Federal Land Policy and Management Act of 1976 directed the BLM to inventory and study its roadless areas for wilderness characteristics throughout the west. The WSAs depicted in this map are a result of that process. They are undeveloped lands that retain their primeval character and are managed to preserve their natural condition.

What is a  wilderness area?

In 1964, the Congress of the United States took a far-sighted action by passing the Wilderness Act, legally designating certain federal lands as Wilderness. Congress preserved these lands: “…in order to assure that an increasing population, accompanied by expanding settlement and growing mechanization does not occupy and modify all areas within the United States and its possessions, leaving no lands designated for preservation and protection in their natural condition”. The Wilderness Act prohibits roads, mining, timber cutting and motorized vehicles in these areas.
