DOWNLOAD EBOOKOregon white oak savannas and woodlands represent a biological and cultural legacy in the Pacific Northwest. Many Oregon white oak stands are deteriorating owing to invasion and eventual overtopping by Douglas-fir or other conifers. Releasing the shade-intolerant oak trees from overtopping conifers can often restore these oak stands. When planning a release operation, there are many factors to consider such as timing and intensity of release, which trees to select for release, and management of the understory. A carefully executed oak release can minimize damage to oak trees, and followup treatments may reduce the spread of invasive plants. This guide answers the most commonly asked questions related to oak release.

DOWNLOAD EBOOKTwelve-year-old Douglas-fir saplings on the Mad River Ranger District, Six Rivers National Forest, Califomia were released by cutting competing vegetation in a 9-foot radius to test the timing and efficacy of this method in plantations older than 1 those in which such work traditionally is done--the I first 5 years. Nine years after release, the average stem diameter (3.60 inches or 9.14 cm) of released Douglas-fir saplings, taken at 12 inches (30 cm) above mean groundline, differed significantly from that of mntrol saplings (2.98 inches or 7.57 cm)(p 0.05), although the average height did nor differ (p 0.05). In spite of this finding, the stem diameter of released saplings was 40 percent less than that needed to comply with regional Forest Service growth objectives. Cost of release averaged $428 per acre or $1058/ha in 1978 dollars.

DOWNLOAD EBOOKNEW YORK TIMES BEST SELLER • From the world's leading forest ecologist who forever changed how people view trees and their connections to one another and to other living things in the forest—a moving, deeply personal journey of discovery “Finding the Mother Tree reminds us that the world is a web of stories, connecting us to one another. [The book] carries the stories of trees, fungi, soil and bears--and of a human being listening in on the conversation. The interplay of personal narrative, scientific insights and the amazing revelations about the life of the forest make a compelling story.”—Robin Wall Kimmerer, author of Braiding Sweetgrass Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; her TED talks have been viewed by more than 10 million people worldwide. In this, her first book, now available in paperback, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths--that trees are not simply the source of timber or pulp, but are a complicated, interdependent circle of life; that forests are social, cooperative creatures connected through underground networks by which trees communicate their vitality and vulnerabilities with communal lives not that different from our own. Simard writes--in inspiring, illuminating, and accessible ways—how trees, living side by side for hundreds of years, have evolved, how they learn and adapt their behaviors, recognize neighbors, compete and cooperate with one another with sophistication, characteristics ascribed to human intelligence, traits that are the essence of civil societies--and at the center of it all, the Mother Trees: the mysterious, powerful forces that connect and sustain the others that surround them. And Simard writes of her own life, born and raised into a logging world in the rainforests of British Columbia, of her days as a child spent cataloging the trees from the forest and how she came to love and respect them. And as she writes of her scientific quest, she writes of her own journey, making us understand how deeply human scientific inquiry exists beyond data and technology, that it is about understanding who we are and our place in the world.

DOWNLOAD EBOOKThis book is dedicated to international cooperation, understanding and peace. It is the end result of several years of cooperative work between scientists of three countries: the United States, Germany, and Portugal. The work presented, however, draws from a much broader base, hopefully achieving the objective of NATO Advanced Research Workshops, which have been established to allow and stimulate the exchange of new ideas and the synthesis of information by scientists of NATO countries. The tasks of the workshop were several; to review established methodologies that have provided insight into ecosystem function and adaptations of plants in mediterranean climate zones; to examine new methodologies that have recently been applied in ecological studies and have provided new types of information; to summarize recent studies in mediterranean regions of plant water relations, photosynthesis and production, mineral nutrition, plant growth and development, and response to fire; to stimulate in particular an exchange of information among scientists of European Mediterranean countries; and to discuss means by which all of these objectives might be even more effectively achieved in the future through cooperative international research efforts. This variety of themes is clearly evident in the layout of the book. Held in Sesimbra, Portugal in October of 1985, the workshop took place in a ..
