What impact does grazing have on Nebraska's range land?

Grazing can have significant effects on Nebraska's rangeland, particularly when it is not managed properly. When livestock graze on vegetation, they can help maintain the health of the ecosystem by controlling plant growth and promoting biodiversity. However, if grazing intensity is too high or there is inadequate recovery time for grazed areas, it can lead to soil compaction and erosion. The removal of plant cover exposes soil to wind and water erosion, which can degrade land productivity and water quality.

Properly managed grazing, on the other hand, can enhance soil health by allowing for nutrient cycling and fostering the growth of a variety of plant species. In this way, grazing can be a tool for ecological management, helping to maintain the balance in the ecosystem when done sustainably.

Other options do not accurately reflect the complexities of grazing's impact. Suggesting that grazing has no effect undermines the significant interactions between grazing livestock and the environment. Claiming that it is always beneficial ignores the fact that poor management can lead to harmful outcomes. Lastly, attributing the primary impact of grazing to urban development overlooks the specific ecological consequences it has on rangeland itself.
