Paperback. Condición: New. Print on Demand. This fascinating book investigates the extensive damage and loss caused by wood-rotting fungi in western white pine stands, particularly those found in British Columbia, Oregon, Washington, Idaho, and Montana. The author delves into the different types of fungi responsible for this damage, revealing that Trametes pini is the most prevalent and destructive. Butt rot caused by Polyporus schweinitzii and root rot caused by Fomes annosus are also discussed. Detailed studies of the fungi's behavior show that they primarily attack older trees, with infection typically starting around 50 years of age. The author also examines the influence of environmental factors, such as soil moisture and elevation, on the severity of the damage. Importantly, the book highlights the economic implications of this issue, estimating a loss of millions of board feet of timber due to decay. To combat this, the author proposes control measures, including proper tree marking and removal of infected materials, to prevent further spread and protect the remaining healthy trees. This book serves as a valuable resource for foresters, landowners, and anyone interested in understanding and mitigating the impact of wood-rotting fungi on western white pine stands. Its insights are crucial for preserving the health and productivity of these ecologically and economically significant forests.
