Question

What is the diff between United States National Forest Service, and Bureau of Land Management?

Answer 1

The short answer is that the Forest Service manages public lands in national forests.  The Bureau of Land Management manages commercial forests on public lands.

Answer 2

Both agencies are part of the Department of Interior.  The U.S. Forest Service is under a different branch than the Bureau of Land Management.  

The U.S. Forest Service is actually a part of the USDA.  It is concerned with "fish and wildlife and parks".  The Bureau of Land Management is concerned with "land and minerals management".  

Sometimes the two divisions work together.  An example is the Santa Rosa and San Jacinta Mountains National Monument in California.

Answer 3

The Bureau of Land Management, with immense holdings in the arid west as well as a large section of western Oregon, is part if the Department of the Interior. The BLM holds very little land east of the Rocky Mountains. Its initial purpose was disposal (sale and settlement) of the public domain. Today it operates mostly to encourage the use of its land by agriculture, mostly for livestock grazing, logging, mining, and (a distinctly last place activity) recreation. Although conservation is part of its mandate, it is usually not concerned with preservation.

The Forest Service is part of the Department of Agriculture, and most of its holdings are designated National Forests. They include lands in many of the states, including states east of the Rockies. Some of the land in the East has been acquired through purchase or retrocession from states or private individuals and firms. Forest management is supposed to yield "the greatest good for the greatest number over the longest time."  In practice that means cutting forests as fast as possible, especially in areas of virgin forests in the western US.
