This report reviews the nature of wind damage in forest stands and relates that damage to the silvicultural systems used or being developed for management of boreal mixedwoods. The report gives detailed consideration to the approaches for minimizing wind damage in released white spruce understory specific to the two-stage harvesting and silvicultural system. The review addresses the individual tree stability, stand stability, and external stability factors such as site characteristics, topography, windiness of the region, and sheltering effects of adjacent stands, and relates these to a framework for recognizing high-risk sites and stands. The report also discusses principles of wind damage management in the context of designing silvicultural systems with incremental wind protection levels.

The primary objective of the study was to test a series of innovative silvicultural treatment packages designed to create mixtures of hardwoods and conifers while monitoring changes in ecological and silvicultural indicators of sustainability. The effects of wind damage on residual trees were monitored at the Stand Level Adaptive Management (SLAM) study site east of Cochrane, Ontario. The goals of this component of the study were to quantify and compare the effects of wind damage between partially harvested and unharvested portions of stands after harvest and to determine their influence on achieving the silvicultural objectives of the partial harvest treatment. Here the authors report the amount and distribution of wind damage in the residual stands at 1, 2, and 4 years after harvest and discuss the effects of this damage on the potential to achieve the desired silvicultural objectives. Specifically, they were interested in the effects of harvest treatments, tree species, direction of fall, stem rot, and stem form on the number and percent of wind damaged trees.--Document.

Forests and any other trees outside the forest play a relevant role all three great UN conventions on Climate Change, on Biodiversity, and on Combating Desertification. The policy processes to implement the measures in these conventions on sub-national, national, regional and international level are extremely complex. And that complexity comes, among other factors, from a blend of different sectoral and national interests, from a large number of scientifically not yet entirely resolved issues and a wide range of different biophysical, social, cultural and political conditions all over the world. The 3rd International DAAD Workshop on “Forests in Climate Change Research and Policy: The Role of Forest Management and Conservation in a Complex International Setting” held in Dubai and Doha along the conference of the parties (COP18) from 28st November to 2nd December had a strong focus on the role of forests and their management in context of international conventions and recent international and national policy. The volume contains 20 papers that are grouped under the topics The Role of Forests and their Management under Climate Change, International Policy Processes, Technical Issues on Remote Sensing, and Country Cases on Forest Management under Climate Change.

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.

Summarises the potential use of alternative silvicultural (harvesting) systems on the productivity of boreal mixedwood forests. Begins with an overview of the ecology of boreal mixedwoods, including physical environment, stand dynamics, and landscape ecology; then provides detailed reviews of modified clear-cutting systems (including strip cutting, patch cutting, and seed-tree cutting), shelterwood systems, and selection systems (including group selection and individual tree selection). Also briefly discusses the environmental considerations that are associated with these systems (effects on soil, water resources, wildlife, and aesthetics). Concludes with a discussion of areas of uncertainty in the application of alternative systems and the perceived problems that have limited their use in boreal mixedwoods.
