AbstractPlant communities in the Great Basin are highly susceptible to invasion by hosts of alien annual species. Highly competitive native annuals did not evolve in the Great Basin to occupy a low seral situation created by intensive grazing. The introduced annual species have been the shadows of domestic livestock since the beginning of agriculture. The alien annuals have highly developed breeding systems which permit adaptation to changing environments.
