Canada ABSTRACT The Inland Temperate Rainforest (ITR) o f British Columbia is a globally unique ecosystem containing areas of high biodiversity, including ancient cedar stands in the upper Fraser River valley. The forest is located in a region historically focused on the economic values of timber. Increased research about and recreational use o f the forest, however, has demonstrated a wider array o f forest values that is yet to be fully documented. The purpose of this research is to document the breadth of forest values surrounding the ancient cedar stands to gain a better understanding o f the significance of this globally unique forest. Through content analysis, as well as surveys conducted in two communities in the ITR, data were collected from trail users, the public, and local residents. Results reveal a broad set o f forest values that inform the ongoing debate currently surrounding the best and highest use o f the ancient cedar stands.

ACKNOWLEDGEMENTS Thank you to the head that helped me formulate my greatest ideas, to the eyes that read every last word of this thesis, to the hands that held me through jo y and frustration, and to the heart that believed in me, unwaveringly, every step o f the way. This would have not been possible without you. Thank you to my mother, my brother, my sister, and my grandparents for loving me so much that I had the confidence to take on this huge project. Thank you to my supervisor for introducing me to the cedars, for bringing a clear mind to an often messy state o f ideas, and for always answering the phone willing to help. Thank you to my committee members for caring about my work. Thank you to my friends, Reza, Heather, and Eric, for being by my side as I explored this northern wilderness, and for making me laugh, often uncontrollably, under the pressure o f this degree. Thank you to Hugh and Kathy, Steve and Nikky, and Nowell, for accepting me into your homes and your hearts, for accommodating me throughout my research, and for inspiring me to feel the unique presence of your forests and your communities. Finally, thank you to the Caledonia Ramblers for their dedication and selfless effort in the creation and maintenance of the Ancient Forest Trail - a pillar o f outdoor recreation in the Robson Valley that visitors continue to enjoy year after year. Chapter 1 INTRODUCTION 1.1 Research Question The Inland Temperate Rainforest (ITR) is a globally unique wetbelt ecosystem located in east-central British Columbia, Canada (B.C.) (Figure 1). Unlike the coastal temperate rainforests for which B.C. is most well-known, the ITR is located more than 500km inland, along the western slopes o f the interior mountains. Few forests in the world parallel its biodiversity value (ILMB 2008), which makes it an important habitat for many threatened or endangered species ranging from mountain caribou to canopy lichens and old-growth (OGF) or ancient forests (Stevenson et al. 2011). Though this rainforest has likely been discovered several times over by First Nations peoples, early European settlers, and loggers, it has only recently been discovered for its ecological and recreational values, especially in the old-growth forests, making it a popular destination for research and outdoor activity. Figure 1. Location of Prince George and McBride in British Columbia 1 Specific hotspots for biodiversity exist within the moist, wet, and very wet Interior Cedar-Hemlock (ICH) subzones o f the ITR, where stands o f old-growth cedar trees are able to reach ages up to 1,000 years or more (B.C. Forest Professional Magazine 2010). A particularly rich ICH subzone is located in the upper Fraser River valley, concentrated between the communities o f Prince George and McBride (see Figure 2). This area supports one of the largest remaining areas o f ancient western redcedars in B.C.’s Interior (B.C. Forest Professional Magazine 2010). Figure 2.
