Grizzly bears are a very high profile species and integrating their requirements within intensively managed forested landscapes is a significant challenge and under intense public and professional scrutiny locally, nationally, and internationally. This project capitalizes on 25 continuous years of research that has radio monitored >140 different grizzly bears to: 1) compare grizzly bear habitat use, behaviour and population characteristics during the first pass of timber harvesting and a major gas exploration program (1978-1985), the period between timber harvesting (1986-1999), and during second pass of timber harvest (2000-2006), 2) test grizzly bear avalanche chute management guidelines, 3) work with managers to implement results into the various scales of land-use planning and development plus continue to publish in peer-reviewed journals and in conference proceedings and maintaining a high profile on international committees and groups such as the IUCN bear specialist group and the International Association for Bear Research and Management
