Applying Crown and Bole Allometry to Management of Boreal Mixedwood Species


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.

Forest Biometrics


Book Description

Forest Biometrics presents the methods of mathematical statistics and biometrics that are significant to forestry. This book explores other fields related to forestry, which are explained with the help of a large number of practical examples. Organized into 25 chapters, this book starts with an overview of the variety of data that play a significant role in forest management, including the age of trees, the damage caused by storms, the fluctuation of timber prices, bark beetle infestation, and timber volume. This text then examines the factors that are responsible for a random distribution of the values in biological experimentation. Other chapters consider the important advantages of sample surveys compared to complete enumerations, include cheaper samples, wider applicability, quick results, and greater accuracy. The final chapter deals with the factors to be considered in determining the best time for harvesting of timber. This book is a valuable resource for students, research project leaders, and practical workers.

Ecology and Recovery of Eastern Old-Growth Forests


Book Description

The landscapes of North America, including eastern forests, have been shaped by humans for millennia, through fire, agriculture, hunting, and other means. But the arrival of Europeans on America’s eastern shores several centuries ago ushered in the rapid conversion of forests and woodlands to other land uses. By the twentieth century, it appeared that old-growth forests in the eastern United States were gone, replaced by cities, farms, transportation networks, and second-growth forests. Since that time, however, numerous remnants of eastern old growth have been discovered, meticulously mapped, and studied. Many of these ancient stands retain surprisingly robust complexity and vigor, and forest ecologists are eager to develop strategies for their restoration and for nurturing additional stands of old growth that will foster biological diversity, reduce impacts of climate change, and serve as benchmarks for how natural systems operate. Forest ecologists William Keeton and Andrew Barton bring together a volume that breaks new ground in our understanding of ecological systems and their importance for forest resilience in an age of rapid environmental change. This edited volume covers a broad geographic canvas, from eastern Canada and the Upper Great Lakes states to the deep South. It looks at a wide diversity of ecosystems, including spruce-fir, northern deciduous, southern Appalachian deciduous, southern swamp hardwoods, and longleaf pine. Chapters authored by leading old-growth experts examine topics of contemporary forest ecology including forest structure and dynamics, below-ground soil processes, biological diversity, differences between historical and modern forests, carbon and climate change mitigation, management of old growth, and more. This thoughtful treatise broadly communicates important new discoveries to scientists, land managers, and students and breathes fresh life into the hope for sensible, effective management of old-growth stands in eastern forests.




Vegetation Monitoring


Book Description

This annotated bibliography documents literature addressing the design and implementation of vegetation monitoring. It provides resources managers, ecologists, and scientists access to the great volume of literature addressing many aspects of vegetation monitoring: planning and objective setting, choosing vegetation attributes to measure, sampling design, sampling methods, statistical and graphical analysis, and communication of results. Over half of the 1400 references have been annotated. Keywords pertaining to the type of monitoring or method are included with each bibliographic entry. Keyword index.







Dynamics, Silviculture and Management of Mixed Forests


Book Description

The capacity of mixed forests to mitigate climate change effects by increasing resilience and lowering risks is pinpointed as an opportunity to highlight the role of tree species rich forests as part of complex socio-ecological systems. This book updates and presents the state-of-the-art of mixed forest performance in terms of regeneration, growth, yield and delivery of ecosystem services. Examples from more than 20 countries in Europe, North Africa and South America provide insights on the interplay between structure and functionining, stability, silviculture and optimization of management of this type of forests. The book also analyses the role of natural mixed forests and mixed plantations in the delivery of ecosystem services and the best modelling strategy to study mixed forest dynamics. The book is intended to serve as a reference tool for students, researchers and professionals concerned about the management of mixed forests in a context of social and environmental change.




First Order Fire Effects Model


Book Description

A First Order Fire Effects Model (FOFEM) was developed to predict the direct consequences of prescribed fire and wildfire. FOFEM computes duff and woody fuel consumption, smoke production, and fire-caused tree mortality for most forest and rangeland types in the United States. The model is available as a computer program for PC or Data General computer.
