Twelve combinations of mechanical site preparation and herbicide levels were tested in an NSR (not satisfactorily restocked) backlog area in the boreal region of British Columbia. This report discusses 4-year microclimate data, installation and maintenance of the monitoring system, seedling survival and growth, and vegetation responses. Results showed that plowing was best for increasing soil temperature, especially in combination with herbicide; winter shearblading was poorest. Site preparation affected seedling growth, with the plowing treatment performing the best. Competing aspen was controlled best with glyphosate applied two growing seasons after mechanical site preparation. Reed grass competition was reduced most by plowing.
