Discusses the improvement of understanding of the role of soil invertebrates in the break-down of litter, cycling of nitrogen, and growth of seedlings in forests of British Columbia. Presence of millipedes in the microcosms of forest floor; Increase of inorganic nitrogen release in the presence of fauna; Rate of breakdown of forest litter.

Tests whether nitrogen (N) cycling in stands of a single tree species increased with increasing mineral soil nitrogen capital. Estimation of N cycling rates in nine stands of Douglas fir; Net N mineralization rate in forest floor; Estimation of carbon and N turnover rates from the litterfall and forest ratio floor.

Investigates long-term effects of nitrogen fertilization on nitrogen availability in coastal Douglas-fir in southeastern Washington. Nitrogen mineralization rates in forest floors; Estimates of nitrogen turnover rates from litterfall/forest floor ratio; Absence of nitrogen fertilization effect on nitrogen cycling.

Presents a study that determined factors limiting the early survivorship of Thuja plicata on northern Vancouver Island, British Columbia. Method of the study; Results and discussion; Conclusion.
