Which of the following statements regarding rangelands in the United States is TRUE? Group of answer choices Public rangelands in the U.S. are managed by the National Park Service with a preservation mandate and thus cannot be used for grazing private livestock. The condition of U.S. rangelands which declined starting in the 1930s, at the time of the Dust Bowl, have continued to be on the decline largely due to the lack of federal legislation. Approximately 50% of the total land area in the United States is rangeland, and most of it is located east of the Mississippi. Restoration of degraded rangeland in the U.S. is a slow and costly process but effective as a result of techniques that include seeding in places where plant cover is sparse or absent, conducting controlled burns to suppress shrubby plants, constructing fences to allow rotational grazing, and controlling invasive weeds.
