The stands of sagebrush resulting from the disappearance of alfa grass face significant changes in their structure. The density and linear recovery rate per unit area are the main parameters describing the dynamics of these stands. These structural parameters are well correlated. The disparity between the recorded values indicates the existence of significant heterogeneity in these stands. This descriptive study underlines the complexity of the setup mode of the studied species.
