What are three ways that the yellow star thistle costs Californians money?

Yellow star thistle costs Californians money through its negative impact on agriculture, as it can outcompete native forage species and reduce the productivity of livestock grazing lands. Additionally, it increases management and control costs for landowners and government agencies tasked with eradicating or controlling its spread. The weed also affects recreational areas, leading to decreased tourism and outdoor activities, which can further impact local economies.
