What are federal rangelands?
Federal rangelands in the United States are rangelands managed by the federal government. Rangelands are defined as composed primarily of grasses or shrub like vegetation suitable for grazing. This includes a diversity of different land cover types in the United States. In the US, 43% of rangelands are owned by the federal government.
The US Forest System is one department that handles rangeland management but there are others as well. You can read more about rangeland management in the US here and about non-federal rangelands here.
