The British Columbia Forest Practices Code (FPC) requires protection of fish-bearing river and stream reaches through riparian reserve zone strips. This paper reports on the application of Fine 2 beam mode RADARSAT multitemporal data to monitoring 65 riparian strips. Eleven Fine 2 beam mode RADARSAT images were acquired between 4 December 1996 and 24 March 1999; these were examined individually and as multi-temporal colour composites (MTCs) for strip-change detection. The 65 riparian strips have a total length of 24.4 km. Eighteen strips comprising 6.3 km (25.8%) are intact. The remaining 47 strips have holes of varying length. The measurement of holes shows that by November 1998, 5.56 km (30.5%) of the 18.2 km of the post-FPC strip length has been decimated by windstorms, and that overall, 7.785 km (31.85%) of the total strip length is decimated. Most decimated strips are found on till-based landforms.
