Early evidence from a suite of fertilization trials on northern Vancouver Island indicated that conifers growing on cedar-hemlock (CH) cutovers were severely deficient in nutrients, particularly N and P, and that fertilization might induce a sustaine

To test the hypothesis that fertilization with municipal biosolids causes a larger long-term tree growth response than fertilization with conventional chemical fertilizers, we measured the height and diameter of planted western redcedar (Thuja plicat

A study was established in coastal British Columbia to determine if repeated nitrogen (N) and phosphorus (P) fertilization negatively influences the reestablishment of salal (Gaultheria shallon Pursh) on cleared and burned cedarhemlock (Thuja plica

Selection of an appropriate silvicultural system that maintains productivity requires an understanding of the effects of harvest type on post-harvest changes in nitrogen availability. The effects on inorganic nitrogen availability and litter decompos

Possible mitigation of nitrate losses associated with clearcuts through harvesting smaller gaps was tested in a high-elevation forest of Engelmann spruce (Picea engelmannii Parry ex Engelm.) and subalpine fir (Abies lasiocarpa (Hook.) Nutt.). We meas

Cedarhemlock forests on Vancouver Island are primarily nitrogen limited and characterized by an under story dominated by the ericaceous shrub salal (Gaultheria shallon Pursh.). In 1984, an experiment was established on regenerating cedarhemlock f

The rate of mass loss of three standard substrates (pine needle litter, aspen leaf litter, and forest floor material) was measured in forests and adjacent clearcuts at 21 sites throughout British Columbia, to test the hypotheses that (i) rates of mas

The problem being addressed is the poor growth of regenerating western redcedar, western hemlock, amabilis fir and Sitka spruce on cutovers of coastal old-growth cedar-hemlock (CH) forests invaded by salal. The approach has been dual; a series of fie

Four commonly held beliefs about litter decomposition rates were tested in a suite of field experiments in British Columbia forests: (1) decomposition is slower in cold (northern and high-elevation) forests, (2) decomposition is faster in clearcuts t

This Stand Establishment Decision Aid (SEDA) for the Coastal Western Hemlock (CWH) biogeoclimatic zone is the first SEDA for the coastal region. We have focused on site series that have been studied since the early 1980s as part of the Salal Cedar He
