In 1987 and 1988, spacing (precommercial thinning) was undertaken on three one-hectare blocks of interior B.C. lodgepole pine and two one- hectare blocks of Coastal Western Hemlock. Each block received four different treatments during spacing. The survival and development of live limbs on cut stumps are documented. Rep- and post-spacing stand densities, clearing-saw productivity and costs are also reported. This project was funded by the Canada/BC Forest Resources Development Agreement (FRDA) under agreement no. F-52-43-102 and FERIC.
