Abstract: | This study investigated the relationship between measured environmental impact and tourists' perception of it, at ten sites in Central Australia. A positive relationship between annual visitation to a site and measurable impact was found, despite the small amount of tourism impact in the area. Tourists' perception of impact varied in degree. A majority identified relevant environmental threats (tourism or introduced species), while a smaller proportion suggested management options to address track spreading, the major impact identified by this study. Overall, environmental conditions were rated lower at sites with a higher intensity of impacts, reflecting some tourists' ability to distinguish impacts. |
