Cedar-hemlock forests on Vancouver Island are primarily nitrogen limited and characterized by an understory dominated by the ericaceous shrub salal (Gaultheria shallon Pursh.). In 1984, an experiment was established on regenerating cedar-hemlock forests to determine the effects of nitrogen and phosphorus (N + P) fertilization and vegetation control on conifer growth. It was hypothesized that these treatments would not only stimulate tree growth, but also improve nutrient supply, stand productivity, and site quality. To test this hypothesis, tree height growth, canopy closure, salal biomass, foliar and forest floor N and P concentrations, and seedling growth on forest floor were measured 10-13 years after treatment. Both salal control and fertilization increased tree growth and canopy cover, and reduced salal biomass. However, only fertilized plots showed changes in site quality measurable 10-13 years following N + P application. Hemlock foliar P concentrations, forest floor total N and P levels, and hemlock height increments were higher in these plots. Forest floors from the fertilized plots also supported greater growth of conifer seedlings. These results suggest that sustained changes to site quality may be achieved with N + P fertilization of cedar-hemlock forests. [ABSTRACT FROM AUTHOR]

Determines the contribution of old-growth and senescent forest stands regenerated through clear-cutting to the biodiversity of wet boreal fir stands in eastern Quebec because overmature stands are becoming scarce in that region. Comparisons of the structure and composition of nonvascular plant communities (mosses, hepatica, lichens, and saprophytic fungi) of old-growth forests with those of mature or senescent fir stands harvested 60 years ago; How the structural diversity of senescent second-growth fir stands becomes similar to that of old-growth stand because of mortality within the overstory; Findings suggest these structural characteristics favour the development of diversified nonvascular plant communities, especially wood-inhabiting species found on slightly decomposed woody debris and soil-inhabiting species that colonize disturbed soils.

Presents an study to analyze aerial photographs in order to assess changes in vegetation composition and distribution in the montane ecoregion of Jasper National Park, in the Rocky Mountains of Alberta, Canada. Use of a quantitative approach for assessing relative vegetation change in repeat ground photographs; Consideration of grasslands, shrub, juvenile forest, and open forests; Findings that the coniferous species is dominant.

Investigates relationships between a network of 53 ring-width chronologies developed from low-elevation stands of Douglas-fir and ponderosa pine in the southern Canadian Cordillera and monthly, seasonal, and annualized climatic parameters (precipitation, temperature, and Palmer Drought Severity Index (PDSI)) using correlation analyses. Details of the study; Results; Discussion of the potential for reconstructing annual (and (or) summer) precipitation for sites across the region.

Reports on changes in terrestrial vertebrate communities from pre- to post-harvest in experimentally created buffer strips (20, 100, 200, and 800 m wide) in a boreal mixedwood forest in Alberta, Canada. Focus on the utility of forested buffer strips as reserves for forest species in managed landscapes; Observations on abundance of small mammals, amphibians, and forest-dependent bird species; Conclusion that 20?100 m buffers would not serve as reserves for forest songbirds in managed landscapes.
