In response to concerns over the influence of visitor activities on site ecosystem health, natural resource managers have expressed an interest in predictive models that might be able to identify affected sites before deleterious impacts have occurred. Hadwen, Arthington and Mosisch (2003) developed one such predictive model, known as the Tourist Pressure Index or TPI. Their TPI aimed to predict visitor numbers to significant sites (pristine lakes) on the World Heritage Listed Fraser Island (Queensland, Australia). In this study, we sought to apply the TPI model to sites on Fraser Island and developed thresholds for Early Warning and Management Action that can be used by natural resource managers to respond to site use before they become degraded from excessive visitor use.
