Tree
Author: David Suzuki
Publisher: Greystone Books Ltd
ISBN: 1771644206
Category : Nature
Languages : en
Pages : 153
Book Description
The story of a single tree, from the moment the seed is released from its cone until, more than five hundred years later, it lies on the forest floor as a nurse log, giving life to ferns, mosses, and hemlocks, even as its own life is ending. In this unique biography, David Suzuki and Wayne Grady tell story that spans a millennium and includes a cast of millions but focuses on a single tree, a Douglas fir, Tree describes in poetic detail the organism’s modest origins that begin with a dramatic burst of millions of microscopic grains of pollen. The authors recount the amazing characteristics of the species, how they reproduce and how they receive from and offer nourishment to generations of other plants and animals. The tree’s pivotal role in making life possible for the creatures around it — including human beings — is lovingly explored. The richly detailed text and Robert Bateman’s original art pay tribute to this ubiquitous organism that is too often taken for granted. Revised edition with a foreword by Peter Wohlleben, author of The Hidden Life of Trees.

Silvicultural Research and the Evolution of Forest Practices in the Douglas-fir Region
Author:
Publisher:
ISBN:
Category : Douglas fir
Languages : en
Pages : 176
Book Description
Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.
