Restoration of relict Garry oak (Quercus garryana) ecosystem along the Colquitz River: A study conducted in Cuthbert Holmes Park Saanich BC, Canada

  • Edmund Strachan University of Victoria


The focus of this study is to restore an area underneath the Garry Oak (Quercus garryana) canopy by utilizing cutting, trimming and thinning techniques in an attempt to mimic natural successional processes. The objective is to open-up the shrub layer, which may increase the potential for native species colonization. Prior to the restoration activity, site surveys and monitoring were conducted by E. Strachan in an urban forested area located within Saanich. BC, on the traditional territories of the Esquimalt and Songhees First Nations. Vegetation surveys were conducted in the summer and fall season to identify native and invasive plant communities found in the area. Based on observations, the study found limited native vegetation, potentially due to the overcrowded invasive vegetation found in the shrub layer. In addition, previous restoration initiatives were discussed to identify ways to increase public participation and build strong relationships with community leaders, which is recommended for future restoration activities.
