Prescott, C.E. and L.L. Blevins, 1999. The Salal Cedar Hemlock Integrated Research Program (SCHIRP): management through understanding. For. Chron. 75: 447-451.

The Salal Cedar Hemlock Integrated Research Program was initiated in 1983 to establish the best operational means for improving the productivity on cutovers of coastal old-growth cedar/hemlock [Thuja plicata/Tsuga heterophylla] forests invaded by salal (Gaultheria shallon) on Vancouver Island. An additional objective was to determine the underlying causes of poor growth in regenerating conifers, including Sitka spruce [Picea sitchensis]. An overview is given of the project management.
