National forest (United States)

[5] The bill was the result of concerted action by Los Angeles-area businessmen and property owners who were concerned by the harm being done to the watershed of the San Gabriel Mountains by ranchers and miners.

There was a plan to develop around 190 million acres of protected National Forests in order to increase logging, grazing, and energy resources.

[1] The National Historic Preservation Act requires the Forest Service to identify, investigate, and protect cultural resources on lands it manages.

Land management of these areas focuses on conservation, timber harvesting, livestock grazing, watershed protection, wildlife, and recreation.

There are management decision conflicts between conservationists and environmentalists and natural resource extraction companies and lobbies (e.g. logging & mining) over the protection and/or use of national forest lands.

Additional conflicts arise from concerns that the grasslands, shrublands, and forest understory are grazed by sheep, cattle, and more recently, rising numbers of elk and mule deer due to loss of predators.
