This book was released on 2005 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a project to assess the accuracy of two instruments for detecting wood decay in trees in order to assess their accuracy & applicability for collecting decay data in Ontario forests. The instruments tested were the Silbert Digital MicroProbe and the Resistograph F400. In general, both instruments measure & record the resistance encountered by a thin probe as it drills through wood. The use of these instruments was compared with visually measuring decay in 60 aspen logs and 71 sugar maple logs. The instruments were also used in boreal mixedwood & tolerant hardwood stands to determine their operability under field conditions.

This book was released on 1969 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2This guide has been prepared to help you estimate the extent and severity of discoloration and decay in northern hardwood trees. Though this certainly is not the last word on the subject, our research in this has progressed to the point where our findings, combined with the findings of others, can be put to practical use. By dissecting living trees and studying the organisms that infect them, we now know that discoloration and decay develop in certain definite patterns. And the patterns of discoloration and decay within the tree can be predicted from external signs. Discoloration and decay are the most serious defects of northern hardwood trees. In speaking of defect, we must distinguish between injury and damage. Injury harms the tree: damage lowers the quality of the wood. For example, a disease like vascular wilt may kill the tree but do no damage to the wood. But an insect like the cambium miner may do very little harm to the tree yet do great damage to the wood. The unseen damage done to a tree is important in the economics of forestry. Every operation in growing a tree, harvesting it, and converting it into products costs time and money. And after all the time and money have been spent on a tree, the product made from it may prove to be not worth the effort; and the tree might have been used more profitably for some other product that does not require high-quality wood. The increased use of veneer offers an illustration. A veneer log brings top prices. But its actual value may not become apparent till it is put on a lathe and peeled. A log that looks very good and sound to the core, may have minute streaks of discoloration scattered all through it, so that all the veneer it produces is badly streaked with defects. On the other hand, a log that has a rotten core surrounded by clear wood may produce the highest quality of veneer. So it is not so important how much discoloration and decay a tree has, but when these defects are in a tree. The pattern of the discoloration and decay- that's the important thing.S3.

Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this book was the desire to systematically organize the extant literature on the conservation of cultural property made of wood, from its beginnings before the Christian Era to the year 2000. Various published reviews and monographs, including Holzkonservierung (Wood Conserva tion) published by the senior author in 1988, have appeared over the years, especially in English and in German. They have provided exemplary treat merit of individual areas or aspects of wood conservation, but a comprehen sive, up-to-date exposition of historic and current developments has been lacking. The diverse professional fields of the authors, as well as their insights into methods of conservation and restoration of wood artifacts in Europe, North America, and Asia provided a solid basis for the success of this under taking. One of the goals during the examination of the literature was that not only well-known conservators and scientists from countries that are leaders in wood conservation should be represented, but that less well-known, often not as readily accessible contributions should also be included. Only in this manner was it possible to draw a comprehensive picture of the national and international state of wood conservation. The Art and Archaeology Technical Abstracts (AATA) of the Getty Institute were very helpful in our efforts to evaluate as many publications as possible.

This book was released on 2013-04-17 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood-destroying fungi play an important role in nature, because they are the only forms of life capable of reducing wood to its initial constituents. However, they can also be dangerous for people and property, as they can impair the stability and fracture-safety of trees. This book gives detailed information, based on new and original scientfic findings, on the examination and effects of the most important species of fungi associated with failure of infected urban trees. In addition, new ways are presented for predicting the advance of decay in the living tree. The subject is illustrated and made easily accessible by numerous colored photos of fungus fruit bodies, defect symptoms, and macroscopic and microscopic pictures of wood decay. A detailed introduction to the fundamentals of wood pathology provides a way into the subjects of applied mycology and tree care for readers without previous special knowledge. Francis W.M.R.
