Age, Size and Regeneration of Old Growth White Pine at Dividing Lake Nature Reserve, Algonquin Park, Ontario


Book Description

The investigators determined the age, mode of regeneration, and diameter growth of white pine in an old growth stand near Dividing Lake, Algonquin Provincial Park. This report presents preliminary results of the investigation, conducted as part of a study to construct ring-width chronologies and to evaluate the role of fire in pine ecosystem regeneration. The results include age distribution, period of regeneration, regeneration class, and correlation between age and growth rate.




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.

Ontario's Old-growth Forests


Book Description

Who would have thought that dwarf cedar trees growing on the Niagara Escarpment could live to be nearly 2000 years old. Or that the small bonsai cedars lining the shorelines of the Canadian shield measure their ages in centuries. Old growth pine trees in Temagami are often over 10 stories tall, but these are young sprouts compared to trees of yesteryear, which were as much as 20 stories high. Ontario's old growth forests are fantastical and mysterious, but who knows where to find one. Most people in this province live within an hour's drive of an old growth forest, but do not know it. The ecology of these stands is engrossing. Fire scars on these trees, for example, provide an indisputable record of forest fire activity in Ontario. Small hemlock saplings, over 100 years old, have been growing at infinitesimal rates, waiting for a gap to open in the forest canopy.
