Abstract
This study tests the applicability of using an Integrated Resource Management (IRM) strategy for more effectively managing riparian zones along electric transmission Rightofways (ROWs). A literature search revealed that while there is an extensive body of information about the importance of riparian zones in creating and maintain aquatic habitat, there has been no research conducted on the effects of transmission powerline vegetation management on riparian zones in British Columbia (BC). Further, an apparent management contradiction exists because electric utilities traditionally manage vegetation on ROWs by cutting all tall trees, whereas in most other situations, tall growing riparian communities are being preserved or restored. In response to this the primary research question for this study is "Is it possible for riparian zone function to be integrated with current vegetation management practices along electric transmission ROWs in BC?" To investigate the problem 12 separate sites across the BC Hydro transmission facility were studied. Variables were selected as indicators of four separate, but functionally related riparian ecosystem functions; energy flow, stream hydrology, bank stability and habitat complexity. Site data was collected, processed and then each case was described and evaluated independently before trends were compared between sites. Vegetation management practices were investigated by reviewing BC Hydro's documents and by conducting guided interviews with BC Hydro staff. Trends between ecosystem function and vegetation management activities were then compared to the literature to complete analysis. The key findings of the study are that traditional vegetation maintenance activities appear to have mixed, site sensitive impacts on the riparian ecosystem functions studied. BC Hydro is implementing a management process designed to integrate site specific issues and varied technical information into workplans. As a result, most of the conditions necessary for integrating riparian function with electric transmission ROWs maintenance are present in BC. Recommendations are provided which describe the remaining conditions necessary for a successful IRM approach to this issue. Hence, the project links IRM theory to a case study example and describes a set of parameters necessary to more effectively manage riparian zones along electric transmission corridors. |
