Book Description
Boreal mixedwood sites, an ecologically & economically valuable component of Ontario's forested landscape, are typically dominated by hardwoods soon after major disturbances such as clear-cutting. Alternative harvesting methods may help reduce the level of competition in the regeneration environment and enrich the conifer content. This report describes field trials in northern Ontario that tested approaches for maintaining or increasing the conifer component in hardwood-dominated stands. The report explains the context & rationale for the trials; documents the locations, designs, layouts, & methods to facilitate reassessment over the long term; and presents responses observed during the first three years of treatment.

Book Description
In this paper, allometry is defined as the proportional size relationship between two parts or attributes of a plant at a single point in time. The paper describes a project to test the effectiveness of crown characteristics for estimating tree growth potential of the main boreal mixedwood species. The investigation was carried out at four fire-origin boreal mixedwood stands in north-west Ontario and several allometric measurements were derived for sample trees (spruce, fir, aspen) at each site. Based on crown & bole allometry calculations, recommendations are made for managing component species in boreal mixedwood stands.

Book Description
This report describes a project to advance knowledge of boreal mixedwood management by testing techniques for achieving productive mixtures of conifers & hardwoods at operational scales. The project is applying treatments in aspen-dominated boreal mixedwood stands at two sites in north-east Ontario. Contrasting approaches are being compared (blended mixtures versus mosaics, partial cutting versus herbicide application, shade-tolerant versus shade-intolerant conifer regeneration) to help identify best practices. Treatment effectiveness is to be assessed by measuring regeneration growth, vegetation succession, soil nutrient dynamics, and changes in invertebrate populations. The report includes information on the site characteristics, treatments, pre- & post-harvest measurement methods, data analysis, knowledge transfer from the project, and project challenges & prospects.

Book Description
This document provides a brief, detailed summary of each presentation in the conference of Complex stand structures and associated dynamics: measurement indices and modelling approaches, in three-page popular summary format. Specifically, short, unedited syntheses were supplied by each author that summarize the essential information of the underlying research study, including scope, objectives, methods, results, references, and major conclusions. The primary purpose is to document the research studies presented for the benefit of the forest science and management communities and foster onsite discussion among conference participants.--Document.
