The Principal Species of Wood


Book Description

Excerpt from The Principal Species of Wood: Their Characteristic Properties The following is a brief untechnical presentation of general features characterizing economically important species of wood. It is the result of notes originally brought together from many already existing sources and later augmented, and verified so far as possible for the present use, by personal observation. The work of preparation has not been as simple as the result would indicate, and although great care has been taken to check each fact, errors do no doubt exist, although it is not believed that there are important ones. Engineers while writing upon woods have, save exceptionally, emphasized strength beyond most other properties. Other works for expert foresters or botanists are of necessity too special, voluminous, fragmental, or technical for the casual student. Some popular books on trees, as distinct from woods, are available. The present form is distinct from these and is intended for those who are not foresters or botanists, but who use woods or desire knowledge of their distinguishing properties. Allusions to trees, historical and other references, aside from those directly regarding woods, are made for completeness and in order to mark, distinguish, or separate the species.




Ecology and Management of Paper Birch and Black Cottonwood in Southern British Columbia


Book Description

Hardwoods have long been disposed of to create coniferous forests of high quality. Recently, there have been concerns that this policy is a mistake, not only because the demand for hardwoods is growing but because of the negative aspects of growing coniferous monocultures. This analysis examined hardwood inventory, ecology, management, and use issues through a summary of hardwood inventory in the Kamloops Forest Region, a field assessment of management practices and stand conditions in two subzones in the region, and a review of literature related to paper birch and black cottonwood, the predominant species in the productive subzones. The field assessment consisted of the sampling of regeneration stands younger than 20 years to identify management practices that were successful for hardwood, conifer, or mixedwood production. Immature-mature stands older than 20 years were sampled across a range of ecosystems to assess their stand structure, species composition, and growth and yield.
