The Salal Cedar Hemlock Integrated Research Program (SCHIRP) was initiated in the 1980s with the twin objectives of understanding the underlying causes of poor conifer regeneration on sites dominated by ericaceous shrubs and of recommending best practices for improving tree growth. This year SCHIRP research will consist of continued maintenance of long-term silvicultural trials established to assess the effects of fertilization on tree growth in different ericaceous-dominated sites. In addition, soil ecology research will address the effect of fertilization on the diversity of ectomycorrhizal fungi associated with hemlock, the potential for mycorrhizal fungi to form associations with both hemlock and salal, and test the hypothesis that excessive moisture, through its influence on the soil microbial community, is the fundamental cause of the poor tree growth on CH cutovers. By continuing this successful tradition of coupling silvicultural trials with cutting-edge ecological research, we will be able to provide recommendations for best management practices of these forest resources with an increased understanding of these ecosystems and factors affecting their sustainable productivity.
