註釋
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.
