Which characteristic is commonly found in areas of deteriorated rangeland?

The identification of short grasses, annuals, and weeds as a common characteristic of deteriorated rangeland is rooted in the ecological impacts that occur when rangeland health declines. In these areas, the loss of native perennial plants often leads to a decrease in vegetation cover and soil health. This deterioration can result from overgrazing, soil erosion, and invasive species taking hold.

When rangeland becomes compromised, the resilience of the ecosystem is weakened, allowing for the establishment of more opportunistic and less competitive plant species, such as annuals and weeds. Annual plants have a shorter life cycle and can quickly colonize disturbed areas, but they do not provide the same ecological benefits as perennial plants, including root structure that helps with soil stabilization and water retention.

Additionally, the presence of short grasses often indicates overgrazing, where desirable native grasses cannot establish or thrive due to continuous pressure from livestock or other herbivores. The transformation of the ecosystem towards these less desirable plant types is a clear signal of ecological degradation in the rangeland environment. Recognizing these signs is crucial for land management and restoration efforts.
