Forest Landscape Ecology
Landscape ecology has generated a wealth of knowledge that could enhance forest policy, but little of this knowledge has found its way into practice. This the first book to introduce landscape ecologists to the discipline of knowledge transfer. The book considers knowledge transfer in general, critically examines aspects that are unique to forest landscape ecology, and reviews case studies of successful applications for policy developers and forest managers in North America.
Simulation Modeling of Forest Landscape Disturbances
Forest landscape disturbances are a global phenomenon. Simulation models are an important tool in understanding these broad scale processes and exploring their effects on forest ecosystems. This book contains a collection of insights from a group of ecologists who address a variety of processes: physical disturbances such as drought, wind, and fire; biological disturbances such as defoliating insects and bark beetles; anthropogenic influences; interactions among disturbances; effects of climate change on disturbances; and the recovery of forest landscapes from disturbances—all from a simulation modeling perspective. These discussions and examples offer a broad synopsis of the state of this rapidly evolving subject.
Emulating Natural Forest Landscape Disturbances
What is a natural forest disturbance? How well do we understand natural forest disturbances and how might we emulate them in forest management? What role does emulation play in forest management? Representing a range of geographic perspectives from across Canada and the United States, this book looks at the escalating public debate on the viability of natural disturbance emulation for sustaining forest landscapes from the perspective of policymakers, forestry professionals, academics, and conservationists. This book provides a scientific foundation for justifying the use of and a solid framework for examining the ambiguities inherent in emulating natural forest landscape disturbance. It ackn...
Red Lake District Black Spruce Aerial Seeding Trial, Fifth Year Results
Aerial seeding as an alternative technique for black spruce regeneration has largely been discontinued in Ontario due to a general failure to produce adequately stocked stands. However, recent trials have led to the development of new prescriptions for aerially seeding black spruce. This report describes a trial designed to examine the effectiveness of these prescriptions in conjunction with two types of site preparation in the Red Lake District. The site chosen was an upland black spruce/jack pine stand situated on deep, gently rolling, fresh to moist silt to silty sand. Fifth year results are presented in terms of seedling densities, comparison between aerially seeded and non-seeded control blocks, comparison between sites prepared using the two methods, and percentage of seedlings in the aerially seeded block that were attributed to the aerial seeding operation.
A Review of Published Knowledge on Post-fire Residuals Relevant to Ontario's Policy Directions for Emulating Natural Disturbance
Fire intensity within forest fires varies as weather and site conditions change, leaving live forest patches, and individual trees, as well as dead structure as standing trees and downed stems. Such remnant structure from pre-burn forests are collectively known as post-fire residuals. This review of the literature is focused on establishing the state of knowledge on post-fire residuals as relevant to directions in Ontario's Forest management guide for natural disturbance pattern emulation (NDPE). It covers information reported for boreal North America, captured from reports that are published and universally accessible. The report includes a description of the methodological steps followed in searching, reviewing, and synthesizing literature; definitions and descriptions of post-fire residuals; abundance and variability of specific types of post-fire residual structure; and associations of post-fire residual structure with forest cover, site conditions, and fire behaviour. It also identifies knowledge gaps and uncertainties about aspects of post-fire residual structure that are relevant to the NDPE guide directions.--Includes text from document.
Evolving Challenges and Changing Expectations for Forestry Extension and Technology Transfer
This document contains summaries of paper presented at the International Union of Forest Research Organizations (IUFRO) conference, which was held on September 21-26, 2008 at Matawa and Ottawa, ON. Paper topics include the role of forestry extension and technology transfer as well as best practises for sustainable management of areas under public or private forest land ownership.
Black Spruce Advance Growth
Advance growth generally refers to stems of layer or seed origin, suppressed at time of logging, which are highly clumped and uneven in height and age. The possibility of integrating advance growth with other silvicultural techniques is a viable option for black spruce since seeding or planting is expensive and desired stocking levels are not always achieved. This paper presents a study that documented the abundance, distribution, and vigour of pre- and post- harvest advance growth in black spruce mixedwood and black spruce-moss sites in north-western Ontario. The study objective was to investigate attributes of advance growth by site type and its potential as a silvicultural option for resource managers in that region. Results are presented of advance growth density, stocking, and selected growth data collected from 36 black spruce stands ranging in age from 50 to 160 years.
