Abstract

Ponderosa pine, the preferred species, accounted for only 15 percent of the residual coniferous reproduction in seed-tree cuttings. Logging slash was machine-piled to encourage pine regeneration. Slash piling reduced the percentage of plots stocked with conifers from 38 to 12 percent. It destroyed 90 percent of the youngest seedlings but only 27 percent of the saplings from 2.0 to 3.5 inches d.b.h.
