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. Pre-and post spacing stand densities, clearing-saw productivity and costs are also reported.
