Book Description
This report describes the results of a reconnaissance-level field study to determine the occurrence of natural white pine regeneration on three areas in northwestern Ontario. The areas included Devon Township in a 90-year-old mixedwood stand containing white pine, red pine, and trembling aspen; Sibley Peninsula in a 140-year-old white pine stand 33 years after an experimental harvesting trial; and Greenwood Lake under a fully stocked 200-year-old white pine stand, in adjacent 10-year-old clearcuts planted or seeded to jack pine, and under a partially cut, naturally regenerating white pine stand 10 years after cutting.

Book Description
Documents the geographical distribution and silvicultural history of white pine in north-western Ontario and discusses future prospects for the species, including management and harvesting strategies. Databases related to current inventories of white pine are compiled and presented in a variety of formats. In addition, silvicultural records and other field surveys undertaken since 1948 are summarised.

Book Description
This study represents an analysis of regeneration processes for eastern white pine (Pinus strohus L.). The objective is to develop an integrated approach to evaluate the influence of factors that, alone and in combination, determine regeneration outcomes. This study is composed of three sections. The first chapter is a literature review of white pine regeneration dynamics. The purpose is to present a process for understanding the regeneration process of a single species and present a conceptual approach to integrated evaluation of influential variables. Six interrelated ecological factors (seed tree density, competition, disturbance, seedbed conditions, soils, and damage agents) were identified and their impact on the regeneration process is evaluated. A conceptual model of the integration approach and two examples of how this approach can be utilized in assessing regeneration operations are presented.

Book Description
Summarizes results of a study conducted to investigate species composition, stand structure, and rate of ingress of natural regeneration during the first 20 years following clear-cutting by the tree-length logging method in north- western Ontario. In 1990 and 1991, 96 plantations in that region were assessed, with the following data collected for planted trees and natural regeneration: tree species, site, seedbed type, height, and density. Some plots were destructively sampled to determine total tree age in order to estimate the rate of ingress of natural regeneration. Results have relevance for predicting the probability of occurrence and density of natural regeneration, and for the timing of regeneration surveys.

Book Description
Increased throughput of carbon-based fossil energy, the destruction of Earth’s forests, and other land use changes have resulted in ever higher levels of waste in the form of greenhouse gases—as well as a diminished capacity of the planet to absorb and store those wastes. This means that to avoid catastrophic global warming and maintain the habitability of Earth by protecting essential soil and water resources, we will need to not only reduce emissions, but also increase carbon storage in the land system. Biosequestration and Ecological Diversity: Mitigating and Adapting to Climate Change and Environmental Degradation discusses ways to remove greenhouse gases from the atmosphere and build soil by changing the way people use and manage land. Principles and Practices for Better Land Management Examining biosequestration in social, economic, and political context, the book reviews recent scientific evidence on climate change and global ecological degradation and explains how the carbon cycle has been transformed by destructive land use practices, such as deforestation and the burning of fossil fuels. It describes the principles of biosequestration and restorative land management practices and discusses the potential of carbon storage. The author offers specific examples of inexpensive, proven practices that build soil, protect scarce water resources, and enhance ecological diversity. He also identifies conservation policies that provide technical assistance and financial resources for ecological protection and restoration. How You Can Help Mitigate Climate Change with a Little Piece of Land Restorative land use and land management practices are critical components of any comprehensive strategy for mitigating and adapting to climate change and global environmental degradation. This book explains how anyone who owns or manages land—from an apartment to a city lot to a farm, forest, park, or even a golf course—can help protect and enhance the biological sequestration of carbon.

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.
