Robson Provincial Park serves as a destination for local, regional, and international visitors while also conserving representative and unique natural resources. Trends such us increasing urbanization, globalization, affluence, and changing values toward nature have radically increased the popularity, the importance and the number of parks of protected areas like Mt. Robson Provincial Park. Research, commencing in the 1970s, indicates that large numbers of visitors threaten backcountry recreation resources within the park. Park staff have responded with increasing management attention in high-use areas, and implementing visitor restrictions. This thesis uses a systematic approach to evaluate the effectiveness of facility and visitor management in resolving impacts to backcountry resources. Specifically, it compares a high-use/ management trail (Berg Lake Trail) to a low-use/management trail (Mt. Fitzwilliam Trail). An integrated, multi-parameter survey established 71 paired plots where data was collected on 32 indicators of trail related resource conditions, management features, and locational/ ecological attributes. While trail width and the proliferation of soeial trails increased with use, other impaets, such as vegetation trampling, and trail incision did not increase with the number of visitors. Some impact indicators, such as wet muddy sections, and exposed rocks and roots, improved with use, a key indication that management, locational and ecological factors are important considerations for managing backcountry resources. These findings are ineorporated into a new model for managing backcountry recreation resources.

Robson Provincial Park Gate 165 Vll Acknowledgements There are a number of people whose assistance and support should be acknowledged. First, my supervisor Sanjay Nepal provided vital guidance throughout the process. I enjoyed working with you and I will always remember the conversations on the road and in the backcountry. The members of my supervisory committee, John Shultis, for being a long-term mentor, friend and teacher since 1994, and Lito Arocena for reviewing the thesis and providing vital comments on the quantitative data and soils. The staff at the Ministry of Water Land and Air Protection in Prince George and at the park also provided background information and logistical support. The National Science and Engineering Research Council funded this work. I would also like to thank the founders of Mount Robson Provincial Park (the second park in BC) for their forethought in conserving the area for future generations to enjoy, and study. Lastly, I would like to thank my wife Laura, for initially supporting my decision to return to university and her continuous support throughout the process.
