Hard rock mining results in extensive land disturbance due to mineral extraction and residual mine waste. This talk addresses identification of above- and below-ground metrics that correlate with vegetation establishment patterns to develop guidance for predicting tipping points for vegetation success or failure on mine waste sites. We have created the University of Arizona Center for Environmentally Sustainable Mining to partner with Arizona copper companies to enable use of these metrics for comprehensive assessment of revegetation strategies under diverse conditions.
