SEEDBED AREA TOTAL SEEDLINGS (SURFACE1 (PINE, SPRUCE & FIR, ALL NATURAL) Figure 6.--!The percentage of naturaZ regeneration occurring on various seedbed k-gpes on a northern Rocky Mountain ecosystem; data derived from Day and Duff3 (1965). CONCLUSIONS A forest manager should know that many important aspects of soil qua1 i ty depend directly on microbial activity, and that this activity is supported to varying deqrees (dependent on temperature and- moisture gradient) by soil organic components. -~hek- fore, managing the soil for organic matter diversity, i .e., preserving or cresting a variety of-microsites, would usually be the method of choice: In no case should soil disturbance, organic matter accumulations, or depletions be extreme over large areas.
