This document presents a synoptic assessment of stream and riparian conditions in the Bowron River watershed, conducted 20-30 years after extensive salvage logging. The study investigates the long-term impacts of harvesting, prompted by a spruce beetle outbreak in the 1970s and 80s, on stream health and surrounding riparian areas, which are crucial for ecological balance. Using the Routine Riparian Effectiveness Evaluation, the assessment compares current conditions to historical watershed assessment procedure rankings, revealing that while some recovery has occurred, the lack of mature vegetation in riparian zones continues to significantly impact stream characteristics, particularly the supply of large woody debris whcih is vital for stream morphology and fish habitat. The authors conclude by offering guidance statements to improve forest management practices, emphasizing the importance of riparian buffers, proper road deactivation, and minimizing soil compaction to mitigate ongoing adverse effects.

This research models the impact of forest harvesting on peak streamflows in a small, snow-dominated watershed in British Columbia. Using a sophisticated hydrological model, the study simulated various clearcutting scenarios to understand how the removal of forest cover influences the magnitude and frequency of high flow events. The findings indicate that forest harvesting consistently increases peak flows, with larger, less frequent events showing a more significant response, though the predicted increases were less than 50% even with complete forest removal. The study highlights the importance of watershed characteristics like topography and size in determining the extent of these changes and emphasizes the ongoing need for research to improve water resource management in forested areas.

This paper details a study examining how different forestry practices, specifically partial cutting methods like group selection and irregular group shelterwood, impact the survival and growth of planted lodgepole pine and interior spruce seedlings. The research compared these outcomes to those in clearcut areas, with the overarching goal of identifying silvicultural systems that can maintain suitable habitat for northern caribou, which rely on terrestrial and arboreal lichens found in these forests. By analyzing seedling survival and growth over five years in relation to different harvesting techniques, the study aimed to determine if partial cutting could effectively regenerate desired tree species while minimizing negative effects on critical caribou forage. The findings provide insights into balancing timber harvesting with the ecological needs of threatened caribou populations in this region.
