In the highly seasonal semi-arid North American sagebrush steppe, physical disturbance changes not just the alpha diversity of the community, but also the beta and phylogenetic beta diversity. Fire disturbance by itself does not have such an effect. Physical disturbance much more than fire fundamentally changes the plant biodiversity that is available to regenerate a plant community postdisturbance in much of the sagebrush steppe.
